Hi there! We're excited to have you as a contributor.
Have questions about this document or anything not covered here? Create a topic using the [AAP tag on the Ansible Forum](https://forum.ansible.com/tag/aap).

## Things to know prior to submitting code
- All code submissions are done through pull requests against the `devel` branch.
- You must use `git commit --signoff` for any commit to be merged, and agree that usage of --signoff constitutes agreement with the terms of [DCO 1.1](./DCO_1_1.md).
- Take care to make sure no merge commits are in the submission, and use `git rebase` vs `git merge` for this reason.
- If collaborating with someone else on the same branch, consider using `--force-with-lease` instead of `--force`. This will prevent you from accidentally overwriting commits pushed by someone else. For more information, see [git push docs](https://git-scm.com/docs/git-push#git-push---force-with-leaseltrefnamegt).
- If submitting a large code change, it's a good idea to create a [forum topic tagged with 'aap'](https://forum.ansible.com/tag/aap), and talk about what you would like to do or add first. This not only helps everyone know what's going on, it also helps save time and effort, if the community decides some changes are needed.
- We ask all of our community members and contributors to adhere to the [Ansible code of conduct](http://docs.ansible.com/ansible/latest/community/code_of_conduct.html). If you have questions, or need assistance, please reach out to our community team at [codeofconduct@ansible.com](mailto:codeofconduct@ansible.com)
## Setting up your development environment
Our team uses [VS Code](https://code.visualstudio.com/) with the [Golang extension](https://marketplace.visualstudio.com/items?itemName=golang.Go) installed for our development environments. The instrustions below will show how to set up an environment using this tool set.
### Fork and clone the Receptor repo
If you have not done so already, you'll need to fork the Receptor repo on GitHub. For more on how to do this, see [Fork a Repo](https://help.github.com/articles/fork-a-repo/).
### Development Requirements
- [Git](https://git-scm.com/book/en/v2)
- [Golang](https://go.dev/doc/install)
- [kind](https://kind.sigs.k8s.io/docs/user/quick-start/)
- [make](https://www.gnu.org/software/make/manual/make.html)
### Build and Run the Development Environment
#### Building Receptor
`make build-all`
#### Building container images
```bash
python -m venv .venv
source .venv/bin/activate
pip install build
make container
```
#### Running tests
`make test`
## What should I work on?
We have a ["good first issue" label](https://github.com/ansible/receptor/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22) we put on some issues that might be a good starting point for new contributors.
Fixing bugs and updating the documentation are always appreciated, so reviewing the backlog of issues is always a good place to start.
## Submitting Pull Requests
Fixes and Features for Receptor will go through the Github pull request process. Submit your pull request (PR) against the `devel` branch.
Here are a few things you can do to help the visibility of your change, and increase the likelihood that it will be accepted:
- No issues when running linters/code checkers
- No issues from unit tests
- Write tests for new functionality, update/add tests for bug fixes
- Make the smallest change possible
- Write good commit messages. See [How to write a Git commit message](https://chris.beams.io/posts/git-commit/).
We like to keep our commit history clean, and will require resubmission of pull requests that contain merge commits. Use `git pull --rebase`, rather than
`git pull`, and `git rebase`, rather than `git merge`.
Sometimes it might take us a while to fully review your PR. We try to keep the `devel` branch in good working order, and so we review requests carefully. Please be patient.
When your PR is initially submitted the checks will not be run until a maintainer allows them to be. Once a maintainer has done a quick review of your work the PR will have the linter and unit tests run against them via GitHub Actions, and the status reported in the PR.
## Reporting Issues
We welcome your feedback, and encourage you to file an issue when you run into a problem.
## Getting Help
If you require additional assistance, please submit your question to the [Ansible Forum](https://forum.ansible.com/tag/aap).

[](https://sonarcloud.io/summary/new_code?id=ansible_receptor)
Receptor is an overlay network intended to ease the distribution of work across a large and dispersed collection of workers. Receptor nodes establish peer-to-peer connections with each other via existing networks. Once connected, the Receptor mesh provides datagram (UDP-like) and stream (TCP-like) capabilities to applications, as well as robust unit-of-work handling with resiliency against transient network failures.
See the readthedocs page for Receptor at:
## Terminology and Concepts
* _Receptor_: The Receptor application taken as a whole, that typically runs as a daemon.
* _Receptorctl_: A user-facing command line used to interact with Receptor, typically over a Unix domain socket.
* _Netceptor_: The networking part of Receptor. Usable as a Go library.
* _Workceptor_: The unit-of-work handling of Receptor, which makes use of Netceptor. Also usable as a Go library.
* _Node_: A single running instance of Receptor.
* _Node ID_: An arbitrary string identifying a single node, analogous to an IP address.
* _Service_: An up-to-8-character string identifying an endpoint on a Receptor node that can receive messages. Analogous to a port number in TCP or UDP.
* _Backend_: A type of connection that Receptor nodes can pass traffic over. Current backends include TCP, UDP and websockets.
* _Control Service_: A built-in service that usually runs under the name `control`. Used to report status and to launch and monitor work.
## How to Get It
The easiest way to check out Receptor is to run it as a container. Images are kept on the Quay registry. To use this, run:
```bash
[docker|podman] pull quay.io/ansible/receptor
[docker|podman] run -d -v /path/to/receptor.conf:/etc/receptor/receptor.conf:Z receptor
```
## Use as a Go library
This code can be imported and used from Go programs. The main libraries are:
* _Netceptor_:
* _Workceptor_:
See the `example/` directory for examples of using these libraries from Go.
## Use as a command-line tool
The `receptor` command runs a Receptor node with access to all included backends and services. See `receptor --help` for details.
The command line is organized into entities which take parameters, like: `receptor --entity1 param1=value1 param2=value1 --entity2 param1=value2 param2=value2`. In this case we are configuring two things, `entity1` and `entity2`, each of which takes two parameters. Distinct entities are marked with a double dash, and bare parameters attach to the immediately preceding entity.
Receptor can also take its configuration from a file in YAML format. The allowed directives are the same as on the command line, with a top-level list of entities and each entity receiving zero or more parameters as a dict. The above command in YAML format would look like this:
```bash
---
- entity1:
param1: value1
param2: value1
- entity2:
param1: value2
param2: value2
```
## Python Receptor and the 0.6 versions
As of June 25th, this repo is the Go implementation of Receptor. If you are looking for the older Python version of Receptor, including any 0.6.x version, it is now located at .

## Purpose
The Kubernetes worker (`kubernetes.go`) enables Receptor to execute work units by creating and managing Kubernetes pods. This component provides a way to run containerized workloads in Kubernetes clusters.
### Core Capabilities
The Kubernetes worker provides:
1. **Creating Kubernetes pods** on demand with specified container images and commands
2. **Streaming input data** to the pod via stdin
3. **Capturing output** (stdout/stderr) from the pod via Kubernetes log streaming or TCP
4. **Managing pod lifecycle** from creation through completion, handling both success and failure scenarios
### Use Cases
The Kubernetes worker can execute any containerized workload, making it suitable for running custom scripts, batch jobs, data processing tasks, or any containerized service that accepts stdin and produces stdout/stderr.
One notable use case is **Ansible Automation Platform (AAP)**, which uses this Kubernetes worker to execute Ansible playbooks in Kubernetes clusters. AAP's Controller service submits work units to Receptor, which then uses this Kubernetes worker to execute them in pods, providing scalability, isolation, and resource management capabilities.
For more details on how work is submitted to Receptor, see:
- [Receptor Work Submit Flow](./receptor_work_submit_flow.md)
## Overview
The Kubernetes worker (`KubeUnit`) implements the `WorkUnit` interface to execute work by:
1. Creating Kubernetes pods with specified container images/commands
2. Streaming stdin data to the pod
3. Streaming stdout/stderr logs from the pod
4. Monitoring pod lifecycle and handling completion/failures
Two streaming methods are supported:
- **Logger Method**: Uses Kubernetes log streaming API for stdout/stderr (recommended for K8s >= 1.23.14)
- **Stdin streaming**: Uses SPDY protocol via Kubernetes attach API (similar to `kubectl attach`)
- **Stdout streaming**: Uses Kubernetes logs API with automatic reconnection support
- **TCP Method**: Pod connects back via TCP (legacy, simpler but less robust)
**What is SPDY?** SPDY is a deprecated HTTP/2 precursor protocol that Kubernetes uses for streaming operations like `kubectl exec` and `kubectl attach`. The SPDY executor creates a multiplexed connection to the Kubernetes API server that allows bidirectional streaming to/from containers. Receptor uses the Kubernetes client-go library's `remotecommand.NewSPDYExecutor()` to create these connections for streaming stdin to pods.
## Architecture Components
### Core Structures
- **KubeUnit**: Main work unit implementation for Kubernetes
- **KubeExtraData**: Stores pod configuration (image, command, namespace, etc.)
- **KubeAPIWrapper**: Wrapper around Kubernetes client-go for testability
- **KubeWorkerCfg**: Configuration object for command-line setup
### Key Interfaces
- **KubeAPIer**: Interface for Kubernetes API operations (allows mocking for tests)
- **WorkUnit**: Base interface that KubeUnit implements

## Key Features
### Resilience Mechanisms
1. **Automatic Reconnection**: Logger method automatically reconnects on stream disconnection
2. **Retry Logic**: Fibonacci backoff for transient errors, with no retry limit for EOF with Running state
3. **Duplicate Detection**: Timestamp-based log line deduplication during reconnections
4. **Timeout Handling**: Configurable timeouts for pod pending state
5. **Graceful Degradation**: Falls back to no-reconnect method for older Kubernetes versions
6. **Long-Running Job Support**: Continues attempting reconnection indefinitely when EOF occurs with Running containers (handles 4-hour log stream timeouts)
### Configuration Flexibility
1. **Multiple Auth Methods**: kubeconfig, incluster, or runtime
2. **Runtime Overrides**: Allow dynamic image/command/params/pod specification
3. **Stream Method Selection**: Choose logger or TCP method
4. **Rate Limiting**: Configurable QPS and burst for API calls
5. **Timeout Configuration**: Environment variables for timeouts and retry counts
## Configuration Options
### Environment Variables
- `RECEPTOR_KUBE_TIMEOUT_START`: Base timeout for retries (default: 1s, max: 1m)
- `RECEPTOR_KUBE_RETRY_COUNT`: Number of retries (default: 5, max: 100)
- `RECEPTOR_KUBE_SUPPORT_RECONNECT`: Enable/disable/auto reconnect (default: enabled)
- `RECEPTOR_KUBE_CLIENTSET_QPS`: API rate limit QPS (default: 100)
- `RECEPTOR_KUBE_CLIENTSET_BURST`: API rate limit burst (default: 10x QPS)
- `RECEPTOR_KUBE_CLIENTSET_RATE_LIMITER`: Rate limiter type (never/always/tokenbucket)
### Worker Configuration
```yaml
- work-kubernetes:
workType: k8s-worker
namespace: default
image: my-image:latest
command: /bin/sh
params: -c
authMethod: incluster
streamMethod: logger
allowRuntimeCommand: false
allowRuntimeParams: true
deletePodOnRestart: true
```
## Work States
1. **WorkStatePending (0)**: Initial state, connecting to Kubernetes or creating pod
2. **WorkStateRunning (1)**: Pod running, streaming data
3. **WorkStateSucceeded (2)**: Work completed successfully. Determined by:
- Exit code 0, OR
- Exit code != 0 but termination reason is "Completed" or "Error" (indicates normal program completion with error)
4. **WorkStateFailed (3)**: Work failed. Determined by:
- Exit code != 0 AND termination reason indicates interruption (OOMKilled, Evicted, etc.), OR
- Other errors occurred during execution (stream errors, pod failures, etc.)
5. **WorkStateCanceled (4)**: Work was canceled, pod deleted
## Error Scenarios and Handling
This section documents how the Kubernetes worker handles various error conditions. Understanding these scenarios is critical for debugging production issues and ensuring reliable job execution.
### Kubernetes API Errors
#### Kube API Timeout
**What happens:**
- Timeouts occur during API calls (Get, Create, Watch, GetLogs)
- The underlying `client-go` library uses the context timeout if provided
- If `podPendingTimeout` is configured, pod readiness checks will timeout
- Watch operations timeout when the context is canceled
**Current handling:**
- ✅ **Pod creation**: Uses `context.WithTimeout()` if `podPendingTimeout` is set. Returns error if timeout exceeded
- ✅ **Pod readiness wait**: `UntilWithSync()` respects context timeout. Returns timeout error
- ⚠️ **API calls without explicit timeout**: Relies on context cancellation or underlying HTTP client timeouts
- ⚠️ **Retry logic**: Retries use Fibonacci backoff but may continue indefinitely if context isn't canceled
**Impact:** Jobs will fail with timeout error. Pod may remain in pending state.
#### Kube API Connection Refused
**What happens:**
- Cannot connect to Kubernetes API server (server down, network issues, firewall)
**Current handling:**
- ❌ **No explicit retry**: Connection errors during `connectToKube()` are returned immediately
- ❌ **No retry in CreatePod()**: TODO comment mentions adding retry logic but not implemented
- ✅ **Retry in log stream**: `kubeLoggingConnectionHandler()` retries up to `GetKubeRetryCount()` times with simple delay (not Fibonacci)
- ✅ **Retry in Get pod**: When resuming, retries 5 times with 200ms delay
- ✅ **Retry in log reconnection**: Main loop retries getting pod with Fibonacci backoff
**Impact:** Initial connection failure causes immediate job failure. However, transient connection issues during execution are retried.
#### Kube API Domain Name Cannot Be Resolved
**What happens:**
- DNS resolution fails for Kubernetes API server hostname
**Current handling:**
- ❌ **No explicit handling**: Treated same as connection refused
- ⚠️ **Error propagation**: Error from `BuildConfigFromFlags()` or `InClusterConfig()` bubbles up to `connectToKube()` which returns error immediately
**Impact:** Job fails at startup with DNS resolution error.
#### Kube API Returns Malformed Payload
**What happens:**
- API server returns invalid JSON/YAML or unexpected response structure
**Current handling:**
- ⚠️ **Partial handling**: Pod YAML/JSON decoding errors are caught in `CreatePod()` and returned
- ❌ **Watch/list responses**: No explicit validation of malformed API responses
- ❌ **Log stream responses**: No validation of log stream format
- ⚠️ **Error propagation**: Depends on `client-go` library to handle malformed responses
**Impact:** Likely to cause panics or unexpected behavior. Partial protection for pod spec decoding.
#### Kube API TLS Error
**What happens:**
- TLS handshake fails, certificate validation errors, certificate expired
**Current handling:**
- ❌ **No explicit handling**: TLS errors from `client-go` are propagated as-is
- ⚠️ **Error location**: TLS errors occur during `NewForConfig()` or API calls
- ⚠️ **Certificate validation**: Handled by `client-go` based on `rest.Config` TLS settings
**Impact:** Job fails with TLS error. No retry logic for TLS errors.
#### Kube API Is Too Old
**What happens:**
- Kubernetes version doesn't support required features (e.g., log stream timestamps, certain API versions)
**Current handling:**
- ✅ **Version detection**: `ShouldUseReconnect()` checks server version via `Discovery().ServerVersion()`
- ✅ **Graceful degradation**: Falls back to no-reconnect logging method for older versions
- ✅ **Compatibility check**: `IsCompatibleK8S()` validates version >= 1.23.14 for reconnect support
- ⚠️ **Feature detection**: Only checks for reconnect support. Other version-dependent features not explicitly checked.
**Impact:** Automatically falls back to legacy method. Should work on older versions.
#### Kube API Is Too New
**What happens:**
- Kubernetes version introduces breaking changes or new required fields
**Current handling:**
- ⚠️ **Limited handling**: `client-go` version compatibility should handle most cases
- ❌ **No explicit new version detection**: Assumes `client-go` handles newer API versions
- ⚠️ **API version negotiation**: Handled automatically by `client-go`
**Impact:** May work if `client-go` supports it, or may fail with API errors.
#### Kube API Authentication Error
**What happens:**
- Invalid kubeconfig, expired tokens, insufficient permissions, wrong namespace
**Current handling:**
- ✅ **kubeconfig errors**: Caught in `connectUsingKubeconfig()`, errors returned immediately
- ✅ **in-cluster errors**: `InClusterConfig()` errors caught
- ❌ **No retry**: Authentication errors are not retried (correctly, as they won't resolve)
- ⚠️ **Permission errors**: API calls return `apierrors.IsForbidden()` which propagates through error handling
- ⚠️ **Token expiration**: No token refresh logic; tokens from kubeconfig expected to be valid
**Impact:** Job fails immediately with authentication error. No automatic token refresh.
### Pod Lifecycle Errors
#### Pod Cannot Be Scheduled
**What happens:**
- No nodes available, resource constraints, node selectors/affinity rules prevent scheduling
**Current handling:**
- ✅ **Watch detects**: `podRunningAndReady()` watches for pod phase changes
- ⚠️ **Timeout handling**: If `podPendingTimeout` is set, pending pods timeout
- ⚠️ **No explicit unscheduled detection**: Doesn't specifically check `pod.Status.Conditions` for `PodScheduled: False`
- ⚠️ **Error message**: Returns generic error from `UntilWithSync()` timeout
**Impact:** Job fails with timeout if pod never schedules. Error message may not clearly indicate scheduling issue.
#### Pod Is Killed
**What happens:**
- Pod evicted due to node pressure, node shutdown, manual pod deletion via kubectl
**Current handling:**
- ✅ **Watch detects deletion during startup**: `podRunningAndReady()` watches for pod events and returns `NotFound` error if `watch.Deleted` event received while waiting for pod to become ready
- ✅ **Watch detects pod phase failures**: Returns `ErrPodFailed` if pod enters `PodFailed` phase, `ErrPodCompleted` if pod enters `PodSucceeded` phase before ready
- ⚠️ **Deletion during execution handled indirectly**: When pod is deleted during job execution:
1. Log stream closes (EOF received)
2. Subsequent `Get()` calls to retrieve pod status return errors (likely `NotFound`)
3. After retries are exhausted (default 5 retries at kubernetes.go:384-406), the job fails with error "Error getting pod X/Y. Error: pods 'X' not found"
4. No explicit `IsNotFound()` check to distinguish pod deletion from other API errors
- ⚠️ **No explicit eviction detection**: Does not check pod conditions or events for eviction-specific signals (e.g., `pod.Status.Reason == "Evicted"`)
- ⚠️ **Generic error handling**: Pod-level failures (eviction, node shutdown) are detected through watch phase changes or API Get() errors, not through specific eviction events
**Impact:** Pod deletion/eviction is detected but reported as generic API errors ("Error getting pod"). Error messages may not clearly indicate whether the pod was deleted, evicted, or experienced another failure. Handling is indirect, relies on watch events (during startup) or API errors (during execution) rather than explicit pod condition checks.
### Container Execution Errors
#### Container Executing Work Is Killed
**What happens:**
- Container running the work is killed or terminates abnormally:
- **OOMKilled**: Container exceeded memory limit (container-level event, not pod-level)
- **SIGKILL/SIGTERM**: Container killed by runtime or scheduler
- **Container runtime issues**: containerd/CRI-O failures
- **Image issues**: Container crashes on startup
**Current handling:**
- ✅ **Container state monitoring**: When EOF received on log stream, `KubeLoggingWithReconnect()` gets fresh pod status and examines container state
- ✅ **Terminated state detection**: Checks `containerState.Terminated` to determine if container has stopped
- ✅ **Exit code inspection**: Reads `containerState.Terminated.ExitCode` to determine exit status
- ✅ **Reason classification**: Checks `containerState.Terminated.Reason` field and uses a whitelist approach:
- **Whitelist reasons** `["Completed", "Error"]`: Container ran to normal completion (even if it exited with error code)
- **All other reasons** (OOMKilled, Evicted, etc.): Execution was interrupted abnormally
- ✅ **Work state determination logic**:
- Exit code 0 → WorkStateSucceeded
- Exit code != 0 + reason in whitelist (`"Completed"` or `"Error"`) → WorkStateSucceeded (normal program completion with error)
- Exit code != 0 + reason NOT in whitelist (e.g., `"OOMKilled"`, `"Evicted"`) → WorkStateFailed and sets `stdoutErr`
- ✅ **Error marking**: Sets `stdoutErr` only if execution interrupted (not for normal error completions)
- ✅ **Last line capture**: Attempts to write last line from log stream before container termination
- ✅ **Detailed logging**: Logs exit code, termination reason, and termination message for all non-zero exits
**Impact:** Container-level terminations are properly detected and classified. Work state determined by both exit code AND termination reason. This correctly distinguishes between:
- Programs that exit with non-zero status intentionally (marked as succeeded if reason is "Completed"/"Error")
- Containers killed by OOM, eviction, or other interruptions (marked as failed)
**Note:** OOMKilled is a **container-level event** that appears in `containerState.Terminated.Reason`, distinct from pod-level eviction events.
#### Other Containers in Pod Are Killed
**What happens:**
- Sidecar containers or init containers fail or are killed
- **Note**: Multi-container pods are only possible when using custom pod specs (Pod parameter). In normal mode (Image/Command/Params), the pod is created with a single container named "worker", so sidecars and init containers are not possible.
**Current handling:**
- ⚠️ **Limited detection**: Only checks `WorkerContainerName` container
- ⚠️ **No sidecar monitoring**: Doesn't check status of other containers in `pod.Status.ContainerStatuses`
- ⚠️ **No init container monitoring**: Doesn't check `pod.Status.InitContainerStatuses`
- ⚠️ **Pod phase impact**: If sidecar/init failures cause pod to fail, pod phase change is detected via watch
- ⚠️ **Init container failures**: May prevent pod from reaching Ready state, detected as timeout during `podRunningAndReady()` watch
**Impact:**
- If worker container unaffected by sidecar failure, job continues normally
- If pod fails due to sidecar/init failure, detected indirectly via pod phase (PodFailed) or timeout waiting for Ready state
- No visibility into which sidecar/init container caused the failure - only that the pod failed
- Custom pod specs allow multiple containers and init containers, but normal mode creates single-container pods only
### Invalid Input Handling
#### Invalid PodTemplate Provided
**What happens:**
- Invalid YAML/JSON, missing required fields, invalid container names, incompatible spec provided in pod template
**Current handling:**
- ✅ **YAML/JSON decoding**: Errors caught in `CreatePod()` when decoding `ked.KubePod`
- ✅ **Worker container validation**: Checks that container named "worker" exists
- ✅ **Required fields**: Kubernetes API validates pod spec during `Create()` call
- ⚠️ **Partial validation**: Only validates worker container exists, not other aspects
- ❌ **No pre-validation**: Invalid specs discovered only when creating pod
**Impact:** Job fails at pod creation with validation error. Error message includes decoding or validation details.
### Long-Running Job Scenarios
#### Job Running for 40+ Hours
**What happens:**
- Very long-running jobs that exceed normal timeouts and log stream limits
**Current handling:**
- ✅ **4-hour log stream timeout**: Kubernetes API closes log streams after 4 hours
- ✅ **Automatic reconnection**: `KubeLoggingWithReconnect()` detects EOF and reconnects with `sinceTime` to avoid duplicates
- ✅ **Timestamp-based deduplication**: `ProcessLogLine()` uses timestamps to skip duplicate lines
- ✅ **Context cancellation handling**: Checks `context.Canceled` during log reading
- ✅ **EOF with Running state**: When EOF is detected but container is still Running, the system continues attempting to reconnect indefinitely (no retry limit) using Fibonacci backoff. This handles both cases: 4-hour log stream timeouts and rapid state transitions to terminated.
- ✅ **Fibonacci backoff**: Uses `GetNextFibonacciValues()` for retry delay calculations (capped at 400 to prevent excessive delays, max sleep duration of 5 minutes)
- ⚠️ **No job timeout**: No maximum job duration enforced by Receptor itself
- ⚠️ **Context cancellation**: Depends on external context cancellation (e.g., from the work submission client)
**Impact:** Jobs can run indefinitely if context not canceled. Log streams automatically reconnect every 4 hours. When EOF occurs with a Running container, the system continues attempting reconnection indefinitely rather than failing, which improves handling of long-running jobs and 4-hour timeout scenarios.
#### Context Cancellation
**What happens:**
- Context is canceled, triggering cleanup of the work unit
- **Important distinction**:
- **Pod startup failures** (before execution begins): `Cancel()` IS called automatically
- **Errors during execution** (after pod running): Errors do NOT cancel context - they just mark job as failed and set error details
- **Context cancellation during execution**: Only from explicit user action or Receptor shutdown, NOT from execution errors
**Cancellation triggers:**
- ✅ **User cancels work**: Via `receptorctl work cancel `
- ✅ **User releases work**: Via `receptorctl work release ` (calls `Cancel()`)
- ✅ **Pod startup failure**: When `CreatePod()` fails (e.g., ErrPodFailed, ErrImagePullBackOff) - automatic cleanup
- ⚠️ **Receptor shutdown**: SIGTERM/SIGINT to the Receptor process (if signal handler cancels contexts)
- ❌ **NOT triggered by execution errors**: Container failures, OOMKilled, log stream errors, etc. do NOT cancel context - they mark job as failed but don't trigger `Cancel()`
**Current handling:**
- ✅ **Context check in log reading**: Detects `context.Canceled` and marks job as failed if not already in terminal state
- ✅ **Context propagation**: Uses `kw.GetContext()` throughout for cancellation propagation
- ✅ **Cancel() method**: Deletes pod via Kubernetes API and marks as `WorkStateCanceled`
- ⚠️ **No graceful shutdown**: No attempt to wait for current operation to complete or allow pod to finish
- ⚠️ **Immediate pod deletion**: Pod is deleted immediately, may interrupt running job and lose partial output
**Impact:**
- Job marked as `WorkStateCanceled`
- Pod deleted from Kubernetes cluster
- Partial output may be lost if job was mid-execution
- For user-initiated cancellation, this is intentional behavior
- For pod startup failures, this is automatic cleanup to remove failed pods
### Log and Disk I/O Errors
#### Log Returned by Kube API Is Too Long
**What happens:**
- Very large log outputs that exceed memory or streaming buffer limits
**Current handling:**
- ✅ **Streaming approach**: Uses streaming reads (`bufio.NewReader`) not loading all logs into memory
- ✅ **Line-by-line processing**: Processes one line at a time
- ⚠️ **No size limits**: No explicit maximum log size limits
- ⚠️ **Disk space**: Depends on available disk space for stdout file
- ⚠️ **Memory**: Should be safe due to streaming, but very long individual lines may cause issues
**AAP Controller capacity checks:**
- ✅ **Memory**: AAP controller checks memory capacity before starting jobs via `mem_capacity` algorithm
- Jobs stay in "pending" state if insufficient memory capacity available
- Reserves ~100MB per fork + 2GB for system services
- ❌ **Disk space**: AAP controller does NOT check disk space before starting jobs
- No pre-flight validation of available disk space
- Jobs can start successfully then fail mid-execution when disk fills
- Work units write stdout to disk without size limits until disk is full
**Impact:** Large logs should work due to streaming, but **disk space exhaustion is a real operational risk**. Jobs will fail with "no space left on device" errors if disk fills during execution. Monitor disk usage on execution nodes, especially `/var/lib/awx` and `/tmp`.
#### Cannot Write Logs to Disk
**What happens:**
- Disk full, permission errors, filesystem errors when writing stdout file
**Current handling:**
- ✅ **Error detection**: Checks `stdout.Write()` errors
- ✅ **Error propagation**: Sets `stdoutErr` and logs error
- ✅ **Job failure**: Marks job as failed when write error occurs
- ⚠️ **No retry**: Write errors are not retried (assumed to be persistent)
- ⚠️ **Partial writes**: If write fails mid-stream, partial data may be in file
**Impact:** Job fails immediately on write error. Partial logs may be present in stdout file.
### Known Unknowns
These scenarios either have unclear handling or require further investigation:
1. **API Server Network Partitions**: What happens if network partitions between Receptor and API server during job execution?
**What happens:**
- Network connectivity is lost between Receptor and the Kubernetes API server (routing issues, network maintenance, infrastructure failures)
- API calls fail with connection refused or timeout errors
- Receptor cannot observe pod state changes during the partition
**Current handling:**
- ✅ **Retry logic**: `KubeLoggingWithReconnect()` retries getting the pod with Fibonacci backoff (default 5 retries, max 100)
- ⚠️ **Limited retries**: With default settings (5 retries, 1s base timeout), total retry time is approximately 12-15 seconds. Partitions longer than this cause job failure
- ⚠️ **Eventual consistency**: If the partition occurs while the pod transitions from Running to Terminated, Receptor may miss the state change and fail the job even if the pod completed successfully
- ⚠️ **No infinite retry**: Retries are finite (default 5, max 100), so long partitions will cause job failure even if the pod is still running or completes successfully
**Impact:** Network partitions longer than the retry window (default ~15 seconds) will cause job failure, potentially even if the pod completes successfully during the partition. The retry logic helps with transient issues but cannot handle extended partitions.
2. **Pod Template Mutations**: What if pod spec is mutated after creation by admission controllers or webhooks? (Unknown: Original spec used, mutations not tracked)

Based on the command: `receptorctl --socket /tmp/control.sock work submit --node execution cat -l hello -f`
This document provides a technical analysis of how Receptor executes work submissions. Receptor is a distributed mesh networking system used by Ansible Automation Platform (AAP) to execute tasks across multiple nodes. When you submit work (like running a command) to a remote execution node, this flow shows how it passes through 4 architectural layers (Python CLI → Control Service → Work Service → Command Worker) from submission to execution and results retrieval.

Exit code = 0
ReceptorCtl->>CtrlSocket: Close websocket connection
ReceptorCtl->>User: Command completed successfully (exit 0)
```
## Key Components
### 1. ReceptorCtl (Python)
- **File**: `receptorctl/receptorctl/cli.py`, `receptorctl/receptorctl/socket_interface.py`
- **Function**: Command-line interface and socket communication
- **Key Classes**: `ReceptorControl`, CLI command handlers
### 2. Control Service (Go)
- **File**: `pkg/controlsvc/controlsvc.go`
- **Function**: Protocol handler for control socket connections
- **Key Functions**: `RunControlSession()`, command routing
### 3. Work Service (Go)
- **File**: `pkg/workceptor/controlsvc.go`, `pkg/workceptor/workceptor.go`
- **Function**: Work unit management and execution
- **Key Functions**: `ControlFunc()`, `AllocateUnit()`, `Start()`
### 4. Command Worker (Go)
- **File**: `pkg/workceptor/command.go`
- **Function**: Executes shell commands as work units
- **Key Functions**: `Start()`, `commandRunner()`
## Work States
1. **WorkStatePending (0)**: Initial state, waiting to start
2. **WorkStateRunning (1)**: Currently executing
3. **WorkStateSucceeded (2)**: Completed successfully
4. **WorkStateFailed (3)**: Failed with error
## Configuration
The `cat` work type is configured via YAML:
```yaml
- work-command:
workType: cat
command: cat
```
This registers a command worker that executes the `cat` shell command when work of type "cat" is submitted.
## Developer Debugging Walkthrough
This section provides specific breakpoint locations and debugging steps to follow the code execution through the codebase.
### Prerequisites
- Set up your development environment with Go and Python debuggers
- Build receptor with debug symbols: `make build-dev` or `go build -gcflags="all=-N -l"`
- **Important**: Install receptorctl in editable/development mode so Python breakpoints work:
```bash
cd receptorctl
pip install -e .
```
This creates a link to your source code instead of copying it, allowing the debugger to hit breakpoints in your workspace files.

### Debugging Steps with VSCode
#### 1. Setup launch.json Configuration
Create or update `.vscode/launch.json` with the following configurations:
```json
{
"version": "0.2.0",
"configurations": [
{
"name": "Debug Receptor Control Node",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${workspaceFolder}/cmd/receptor-cl/receptor.go",
"args": [
"--config",
"${workspaceFolder}/test-configs/control.yml"
],
"env": {},
"showLog": true
},
{
"name": "Debug Receptor Execution Node",
"type": "go",
"request": "launch",
"mode": "debug",
"program": "${workspaceFolder}/cmd/receptor-cl/receptor.go",
"args": [
"--config",
"${workspaceFolder}/test-configs/execution.yml"
],
"env": {},
"showLog": true
},
{
"name": "Debug ReceptorCtl",
"type": "debugpy",
"request": "launch",
"module": "receptorctl.cli",
"cwd": "${workspaceFolder}/receptorctl",
"args": [
"--socket",
"/tmp/control.sock",
"work",
"submit",
"--node",
"execution",
"cat",
"-l",
"hello",
"-f"
],
"console": "integratedTerminal",
"justMyCode": false,
"env": {
"PYTHONWARNINGS": "ignore::RuntimeWarning"
}
}
],
"compounds": [
{
"name": "Debug Control + Execution Nodes",
"configurations": [
"Debug Receptor Control Node",
"Debug Receptor Execution Node"
],
"stopAll": true
}
]
}
```
#### 2. Start Debugging
**Important**: Before debugging, ensure receptorctl is installed in editable mode (see Prerequisites above). This is required for Python breakpoints to work.
1. **Launch Both Nodes Together**:
- Open VSCode Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
- Select "Debug: Select and Start Debugging"
- Choose "Debug Control + Execution Nodes" compound configuration
- Both receptor nodes will start with debugger attached
- Wait for nodes to be ready (watch for "control service listening" in debug console)
2. **Set Breakpoints for Diagram 1 (Work Submission)**:
**Python breakpoints:**
- `receptorctl/receptorctl/cli.py` - `submit()` function
- `receptorctl/receptorctl/socket_interface.py` - `submit_work()` function
**Go breakpoints:**
- `pkg/controlsvc/controlsvc.go` - `RunControlSession()`
- `pkg/workceptor/controlsvc.go` - `ControlFunc()` (submit case)
- `pkg/workceptor/workceptor.go` - `AllocateUnit()`
- `pkg/workceptor/command.go` - `Start()`
- `pkg/workceptor/command.go` - `commandRunner()`
3. **Set Breakpoints for Diagram 2 (Results Retrieval)**:
**Python breakpoints:**
- `receptorctl/receptorctl/socket_interface.py` - Results retrieval code (after work submission)
**Go breakpoints:**
- `pkg/workceptor/controlsvc.go` - `ControlFunc()` (results case)
- `pkg/workceptor/workceptor.go` - `GetResults()`
- `pkg/workceptor/controlsvc.go` - `ControlFunc()` (status case)
4. **Debug ReceptorCtl Client**:
- After receptor nodes are running and ready, start the Python debugger
- Select "Debug ReceptorCtl" configuration from the debug dropdown
- The command will execute and hit breakpoints in both flows sequentially
5. **Step Through Execution**:
- Use VSCode debug controls (Continue, Step Over, Step Into, Step Out)
- Watch the call stack across both Go processes
- Inspect variables in the Debug sidebar
- Observe the data flow:
- **First flow**: Submission → Execution → Completion
- **Second flow**: Results retrieval → Status check → Exit
### Key Variables to Watch
- **In receptorctl**: `worktype`, `node`, `payload_data`, `commandMap`
- **In control service**: `cmdBytes`, `jsonData`, `cmd`, `params`
- **In work service**: `workNode`, `workType`, `workParams`, `worker`
- **In command worker**: `cw.command`, `cw.baseParams`, `cmd`
- **In command runner**: `command`, `params`, `unitdir`, `status`
### Log Analysis
Enable debug logging to see the full flow:
Look for these log patterns:
```bash
# "Client connected to control service"
# "Work unit created with ID"
# "Running: PID"
# "Streaming results for work unit"
This walkthrough allows developers to trace the complete execution path from CLI input to command execution and result output.

Receptor welcomes community contributions! See the :ref:`dev_guide` for information about receptor development.
-------------
Pull requests
-------------
Contributions to Receptor go through the Github pull request process.
An initial checklist for your change to increase the likelihood of acceptance:
- No issues when running linters/code checkers
- No issues from unit/functional tests
- Write descriptive and meaningful commit messages. See `How to write a Git commit message `_ and `Learn to write good commit message and description `_.
===============
Release process
===============
Before starting the release process verify that `make test` and `go test tests/goroutines/simple_config.go` tests pass.
Maintainers have the ability to run the `Stage Release`_ workflow. Running this workflow will:
- Build and push the container image to ghcr.io. This serves as a staging environment where the image can be tested.
- Create a draft release at ``_
After the draft release has been created, edit it and populate the description. Once you are done, click "Publish release".
After the release is published, the `Promote Release `_ workflow will run automatically. This workflow will:
- Publish ``receptorctl`` to `PyPI `_.
- Pull the container image from ghcr.io, re-tag, and push to `Quay.io `_.
- Build binaries for various OSes/platforms, and attach them to the `release `_.
.. note::
If you need to re-run `Stage Release`_ more than once, delete the tag beforehand to prevent the workflow from failing.

---------
Debugging
---------
^^^^^^^^^^^
Unix Socket
^^^^^^^^^^^
If you don't want to use receptorctl to control nodes, `socat ` can be used to interact with unix sockets directly.
Example:
.. code-block:: bash
echo -e '{"command": "work", "subcommand": "submit", "node": "execution", "worktype": "cat", }\n"Hi"' | socat - UNIX-CONNECT:/tmp/control.sock
-------
Linters
-------
All code must pass a suite of Go linters.
There is a pre-commit yaml file in the Receptor repository that points to the linter suite.
It is strongly recommmended to install the pre-commit yaml so that the linters run locally on each commit.
.. code-block:: bash
cd $HOME
go get github.com/golangci/golangci-lint/cmd/golangci-lint
pip install pre-commit
cd receptor
pre-commit install
See `Pre commit `_ and `Golangci-lint `_ for more details on installing and using these tools.
-------
Testing
-------
^^^^^^^^^^^
Development
^^^^^^^^^^^
Write unit tests for new features or functionality.
Add/Update tests for bug fixes.
^^^^^^^
Mocking
^^^^^^^
We are using mockgen to generate mocks for our unit tests. The mocks are living inside of a package under the real implementation, prefixed by ``mock_``. An example is the package mock_workceptor under pkg/workceptor.
We use go generate to generate our mocks. To generate all the mocks in receptor:
.. code-block:: bash
make generate
To add a mock to go generate you will need to add a line to the `generate.go` file in the root of the repository.
In order to genenerate a mock for a particular file, run:
.. code-block:: bash
mockgen -source=pkg/filename.go -destination=pkg/mock_pkg/mock_filename.go
For example, to create/update mocks for Workceptor, we can run:
.. code-block:: bash
mockgen -source=pkg/workceptor/workceptor.go -destination=pkg/workceptor/mock_workceptor/workceptor.go
After validating the mockgen command generates the mocks correctly you can add this command to the `generate.go` file.
To remove a mock you will need to remove the associated line in the `generate.go` file.
Then the following commands to generate a fresh set of mocks:
.. code-block:: bash
make generate-clean
make generate
^^^^^^^^^^
Kubernetes
^^^^^^^^^^
Some of the tests require access to a Kubernetes cluster; these tests will load in the kubeconfig file located at ``$HOME/.kube/config``. One simple way to make these tests work is to start minikube locally before running ``make test``. See https://minikube.sigs.k8s.io/docs/start/ for more information about minikube.
To skip tests that depend on Kubernetes, set environment variable ``export SKIP_KUBE=1``.
^^^^^^^^^
Execution
^^^^^^^^^
Pull requests must pass a suite of unit and integration tests before being merged into ``devel``.
``make test`` will run the full test suite locally.
-----------
Source code
-----------
The following sections help orient developers to the Receptor code base and provide a starting point for understanding how Receptor works.
^^^^^^^^^^^^^^^^^^^^^
Parsing receptor.conf
^^^^^^^^^^^^^^^^^^^^^
Let's see how items in the config file are mapped to Golang internals.
As an example, in tcp.go
.. code-block:: go
cmdline.RegisterConfigTypeForApp("receptor-backends",
"tcp-peer", "Make an outbound backend connection to a TCP peer", TCPDialerCfg{}, cmdline.Section(backendSection))
"tcp-peer" is a top-level key (action item) in receptor.conf
.. code-block:: yaml
tcp-peers:
- address: localhost:2222
``RegisterConfigTypeForApp`` tells the cmdline parser that "tcp-peer" is mapped to the ``TCPDialerCfg{}`` structure.
``main()`` in ``receptor.go`` is the entry point for a running Receptor process.
In ``receptor.go`` (modified for clarity):
.. code-block:: go
cl.ParseAndRun("receptor.conf", []string{"Init", "Prepare", "Run"})
A Receptor config file has many action items, such as ```node``, ``work-command``, and ``tcp-peer``. ``ParseAndRun`` is how each of these items are instantiated when Receptor starts.
Specifically, ParseAndRun will run the Init, Prepare, and Run methods associated with each action item.
Here is the Prepare method for ``TCPDialerCfg``. By the time this code executes, the cfg structure has already been populated with the data provided in the config file.
.. code-block:: go
// Prepare verifies the parameters are correct.
func (cfg TCPDialerCfg) Prepare() error {
if cfg.Cost <= 0.0 {
return fmt.Errorf("connection cost must be positive")
}
return nil
}
This simply does a check to make sure the provided Cost is valid.
The Run method for the ``TCPDialerCfg`` object:
.. code-block:: go
// Run runs the action.
func (cfg TCPDialerCfg) Run() error {
logger.Debug("Running TCP peer connection %s\n", cfg.Address)
host, _, err := net.SplitHostPort(cfg.Address)
if err != nil {
return err
}
tlscfg, err := netceptor.MainInstance.GetClientTLSConfig(cfg.TLS, host, "dns")
if err != nil {
return err
}
b, err := NewTCPDialer(cfg.Address, cfg.Redial, tlscfg)
if err != nil {
logger.Error("Error creating peer %s: %s\n", cfg.Address, err)
return err
}
err = netceptor.MainInstance.AddBackend(b, cfg.Cost, nil)
if err != nil {
return err
}
return nil
}
This gets a new TCP dialer object and passes it to the netceptor ``AddBackend`` method, so that it can be processed further.
``AddBackend`` will start proper Go routines that periodically dial the address defined in the TCP dialer structure, which will lead to a proper TCP connection to another Receptor node.
In general, when studying how the start up process works in Receptor, take a look at the ``Init``, ``Prepare``, and ``Run`` methods throughout the code, as these are the entry points to running those specific components of Receptor.
^^^^
Ping
^^^^
Studying how pings work in Receptor will provide a useful glimpse into the internal workings of netceptor -- the main component of Receptor that handles connections and data traffic over the mesh.
``receptorctl --socket /tmp/foo.sock ping bar``
The control-service on `foo` will receive this command and subsequently call the following,
**ping.go::ping**
.. code-block:: go
func ping(nc *netceptor.Netceptor, target string, hopsToLive byte) (time.Duration, string, error) {
pc, err := nc.ListenPacket("")
``target`` is the target node, "bar" in this case.
``nc.ListenPacket("")`` starts a new ephemeral service and returns a ``PacketConn`` object. This is a datagram connection that has a WriteTo() and ReadFrom() method for sending and receiving data to other nodes on the mesh.
**packetconn.go::ListenPacket**
.. code-block:: go
pc := &PacketConn{
s: s,
localService: service,
recvChan: make(chan *messageData),
advertise: false,
adTags: nil,
connType: ConnTypeDatagram,
hopsToLive: s.maxForwardingHops,
}
s.listenerRegistry[service] = pc
return pc, nil
``s`` is the main netceptor object, and a reference to the PacketConn object is stored in netceptor's ``listenerRegistry`` map.
**ping.go::ping**
.. code-block:: go
_, err = pc.WriteTo([]byte{}, nc.NewAddr(target, "ping"))
Sends an empty message to the address "bar:ping" on the mesh. Recall that nodes are analogous to DNS names, and services are like port numbers.
``WriteTo`` calls ``sendMessageWithHopsToLive``
**netceptor.go::sendMessageWithHopsToLive**
.. code-block:: go
md := &messageData{
FromNode: s.nodeID,
FromService: fromService,
ToNode: toNode,
ToService: toService,
HopsToLive: hopsToLive,
Data: data,
}
return s.handleMessageData(md)
Here the message is constructed with essential information such as the source node and service, and the destination node and service. The Data field contains the actual message, which is empty in this case.
``handleMessageData`` calls ``forwardMessage`` with the ``md`` object.
**netceptor.go::forwardMessage**
.. code-block:: go
nextHop, ok := s.routingTable[md.ToNode]
The current node might not be directly connected to the target node, and thus netceptor needs to determine what is the next hop to pass the data to. ``s.routingTable`` is a map where the key is a destination ("bar"), and the value is the next hop along the path to that node. In a simple two-node setup with `foo` and `bar`, ``s.routingTable["bar"] == "bar"``.
**netceptor.go::forwardMessage**
.. code-block:: go
c, ok := s.connections[nextHop]
c.WriteChan <- message
``c`` here is a ``ConnInfo`` object, which interacts with the various backend connections (UDP, TCP, websockets).
``WriteChan`` is a golang channel. Channels allows communication between separate threads (Go routines) running in the application. When `foo` and `bar` had first started, they established a backend connection. Each node runs the netceptor runProtocol go routine, which in turn starts a protoWriter go routine.
**netceptor.go::protoWriter**
.. code-block:: go
case message, more := <-ci.WriteChan:
err := sess.Send(message)
So before the "ping" command was issued, this protoWriter Go routine was already running and waiting to read messages from WriteChan.
``sess`` is a BackendSession object. BackendSession is an abstraction over the various available backends. If `foo` and `bar` are connected via TCP, then ``sess.Send(message)`` will pass along data to the already established TCP session.
**tcp.go::Send**
.. code-block:: go
func (ns *TCPSession) Send(data []byte) error {
buf := ns.framer.SendData(data)
n, err := ns.conn.Write(buf)
``ns.conn`` is net.Conn object, which is part of the Golang standard library.
At this point the message has left the node via a backend connection, where it will be received by `bar`.
Let's review the code from `bar`'s perspective and how it handles the incoming message that is targeting its "ping" service.
On the receiving side, the data will first be read here
**tcp.go::Recv**
.. code-block:: go
n, err := ns.conn.Read(buf)
ns.framer.RecvData(buf[:n])
Recv was called in protoReader Go routine, similar to the protoWriter when the message sent from `foo`.
Note that ``ns.conn.Read(buf)`` might not contain the full message, so the data is buffered until the ``messageReady()`` returns true. The size of the message is tagged in the message itself, so when Recv has received N bytes, and the message is N bytes, Recv will return.
**netceptor.go::protoReader**
.. code-block:: go
buf, err := sess.Recv(1 * time.Second)
ci.ReadChan <- buf
The data is passed to a ReadChan channel.
**netceptor.go::runProtocol**
.. code-block:: go
case data := <-ci.ReadChan:
message, err := s.translateDataToMessage(data)
err = s.handleMessageData(message)
The data is read from the channel, and deserialized into an actual message format in ``translateDataToMessage``.
**netceptor.go::handleMessageData**
.. code-block:: go
if md.ToNode == s.nodeID {
handled, err := s.dispatchReservedService(md)
This checks whether the destination node indicated in the message is the current node. If so, the message can be dispatched to the service.
"ping" is a reserved service in the netceptor instance.
.. code-block:: go
s.reservedServices = map[string]func(*messageData) error{
"ping": s.handlePing,
}
**netceptor.go::handlePing**
.. code-block:: go
func (s *Netceptor) handlePing(md *messageData) error {
return s.sendMessage("ping", md.FromNode, md.FromService, []byte{})
}
This is the ping reply handler. It sends an empty message to the FromNode (`foo`).
The FromService here is not "ping", but rather the ephemeral service that was created from ``ListenPacket("")`` in ping.go on `foo`.
With ``trace`` enabled in the Receptor configuration, the following log statements show the reply from ``bar``,
.. code-block:: bash
TRACE --- Received data length 0 from foo:h73opPEh to bar:ping via foo
TRACE --- Sending data length 0 from bar:ping to foo:h73opPEh
So the ephemeral service on `foo` is called h73opPEh (randomly generated string).
From here, the message from `bar` will passed along in a very similar fashion as the original ping message sent from `foo`.
Back on node `foo`, the message is received receive the message where it is finally handled in ping.go
**ping.go::ping**
.. code-block:: go
_, addr, err := pc.ReadFrom(buf)
.. code-block:: go
case replyChan <- fromNode:
.. code-block:: go
case remote := <-replyChan:
return time.Since(startTime), remote, nil
The data is read from the PacketConn object, written to a channel, where it is read later by the ping() function, and ping() returns with the roundtrip delay, ``time.Since(startTime)``.

Creating a basic 3-node network
###############################
In this section, we will create a three-node network.
The three nodes are: foo, bar, and baz.
`foo -> bar <- baz`
foo and baz are directly connected to bar with TCP connections.
foo can reach baz by sending network packets through bar.
***********************
Receptor configurations
***********************
1. Create three configuration files, one for each node.
``foo.yml``
.. code-block:: yaml
- node:
id: foo
- control-service:
service: control
filename: /tmp/foo.sock
- tcp-peer:
address: localhost:2222
- log-level:
level: debug
...
``bar.yml``
.. code-block:: yaml
---
- node:
id: bar
- control-service:
service: control
filename: /tmp/bar.sock
- tcp-listener:
port: 2222
- log-level:
level: debug
...
``baz.yml``
.. code-block:: yaml
---
- node:
id: baz
- control-service:
service: control
filename: /tmp/baz.sock
- tcp-peer:
address: localhost:2222
- log-level:
level: debug
- work-command:
workType: echo
command: bash
params: "-c \"while read -r line; do echo $line; sleep 1; done\""
allowruntimeparams: true
...
2. Run the services in separate terminals.
.. code-block:: bash
./receptor --config foo.yml
.. code-block:: bash
./receptor --config bar.yml
.. code-block:: bash
./receptor --config baz.yml

Getting started with Receptor
#############################
Receptor is an overlay network that distributes work across large and dispersed collections of worker nodes.
Receptor nodes establish peer-to-peer connections through existing networks.
Once connected, the Receptor mesh provides datagram (UDP-like) and stream (TCP-like) capabilities to applications, as well as robust unit-of-work handling with resiliency against transient network failures.

Ansible Receptor documentation
###############################
Receptor is an overlay network intended to ease the distribution of work across a large and dispersed collection of workers. Receptor nodes establish peer-to-peer connections with each other via existing networks. Once connected, the receptor mesh provides datagram (UDP-like) and stream (TCP-like) capabilities to applications, as well as robust unit-of-work handling with resiliency against transient network failures.

*******************
Installation guide
*******************
Download and extract precompiled binary for your OS and platform from `the releases page on GitHub `_
Alternatively, you can compile Receptor from source code (Golang 1.23+ required)
.. code-block:: bash
make receptor
Test the installation with the following commands:
.. code-block:: bash
receptor --help
receptor --version
The preferred way to interact with Receptor nodes is to use the ``receptorctl`` command line tool
.. code-block:: bash
pip install receptorctl
``receptorctl`` will be used in various places throughout this documentation.

- Adds a Receptor parameter in key=value format.
* - ``-f``, ``--follow``
- Keeps Receptorctl to remain attached to the job and displays the job results.
* - ``-l``, ``--payload-literal <>``
- Uses the value of ``<>`` as the literal unit of work data.
* - ``-n``, ``--no-payload``
- Sends an empty payload.
* - ``--node <>``
- Specifies the Receptor node on which the work runs. The default is the local node.
* - ``-p``, ``--payload <>``
- Specifies the file that contains data for the unit of work. Specify ``-`` for standard input (stdin).
* - ``--rm``
- Releases the work unit after completion.
* - ``--signwork``
- Digitally signs remote work submissions to standard output (stdout).
* - ``--tls-client <>``
- Specifies the TLS client that submits work to a remote node.
* - ``--ttl <>``
- Specifies the time to live (TTL) for remote work requests in ``##h##m##s`` format; for example ``1h20m30s`` or ``30m10s``. Use the ``receptorctl work list`` command to display units of work on Receptor nodes and determine appropriate TTL values.

Receptor Roadmaps
=================
The ``Receptor`` team develops a roadmap for each major Receptor release.
The latest roadmap shows current work; older roadmaps provide a history of the
project. We don't publish roadmaps for minor or subminor versions. So 2.0 and
3.0 have roadmaps, but 2.1.0 and 2.10.1 do not.
We incorporate team and community feedback in each roadmap, and aim for further
transparency and better inclusion of both community desires and submissions.
Each roadmap offers a *best guess*, based on the ``Receptor`` team's experience
and on requests and feedback from the community, of what will be included in a
given release. However, some items on the roadmap may be dropped due to time
constraints, lack of community maintainers, and so on.
Each roadmap is published both as an idea of what is upcoming in ``Receptor``,
and as a medium for seeking further feedback from the community.
You can submit feedback on the current roadmap by:
- Creating issue on GitHub in `ansible/receptor repository `_
Go to `Ansible forum `_ to join the community discussions.

Kubernetes Environment Variables
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following environment variables can be used to configure Kubernetes worker behavior:
.. note::
The environment variable ``RECEPTOR_OPEN_LOGSTREAM_TIMEOUT`` has been replaced with ``RECEPTOR_KUBE_TIMEOUT_START``. The new variable controls the initial sleep duration for all Kubernetes API retry operations using Fibonacci backoff, not just log stream timeouts.
.. list-table:: Kubernetes Environment Variables
:header-rows: 1
:widths: auto
* - Variable
- Description
- Default value
- Valid range
- Type
* - ``RECEPTOR_KUBE_TIMEOUT_START``
- Initial timeout duration between Kubernetes API retry attempts. Valid time units: "ns", "ms", "s", "m", "h"
- 1s
- Any valid duration up to 1m
- string (duration)
* - ``RECEPTOR_KUBE_RETRY_COUNT``
- Number of retry attempts for Kubernetes API operations. Uses exponential backoff with Fibonacci-like sequence.
- 5
- 1-100
- int
**Important Notes:**
- **Fibonacci Backoff**: Retry delays increase by Fibonacci increments. For example, with ``RECEPTOR_KUBE_TIMEOUT_START=1s``, retry delays will be: 1s, 2s, 3s, 5s, 8s, etc.
- **Timeout Start Limit**: ``RECEPTOR_KUBE_TIMEOUT_START`` values exceeding 1 minute will be capped at the maximum of 1 minute.
- **Maximum Sleep Duration**: Individual sleep durations are capped at 5 minutes to prevent extremely long waits.
- **Performance Impact**: High retry counts can result in very long wait times. Consider the total time impact when setting these values.

Connecting nodes
================
.. contents::
:local:
Connect nodes through Receptor backends.
TCP, UDP, and websockets are currently supported.
For example, you can connect one Receptor node to another using the ``tcp-peers`` and ``tcp-listeners`` configuration options.
Similarly you can connect Receptor nodes using the ``ws-peers`` and ``ws-listeners`` configuration options.
.. image:: mesh.png
:alt: Connected nodes as netceptor peers
foo.yml
.. code-block:: yaml
---
version: 2
node:
id: foo
log-level:
level: Debug
tcp-listeners:
- port: 2222
bar.yml
.. code-block:: yaml
---
version: 2
node:
id: bar
log-level:
level: Debug
tcp-peers:
- address: localhost:2222
fish.yml
.. code-block:: yaml
---
version: 2
node:
id: fish
log-level:
level: Debug
tcp-peers:
- address: localhost:2222
If we start the backends for each of these configurations, this will form a three-node mesh. Notice `bar` and `fish` are not directly connected to each other. However, the mesh allows traffic from `bar` to pass through `foo` to reach `fish`, as if `bar` and `fish` were directly connected.
From three terminals we can start this example by using the container we provide on quay.io
.. code-block:: bash
podman run -it --rm --network host --name foo -v${PWD}/foo.yml:/etc/receptor/receptor.conf quay.io/ansible/receptor
.. code-block:: bash
podman run -it --rm --network host --name bar -v${PWD}/bar.yml:/etc/receptor/receptor.conf quay.io/ansible/receptor
.. code-block:: bash
podman run -it --rm --network host --name fish -v${PWD}/fish.yml:/etc/receptor/receptor.conf quay.io/ansible/receptor
Logs from `fish` shows a successful connection to `bar` via `foo`.

Configuring backends
--------------------
``redial`` If set to true, receptor will automatically attempt to redial and restore connections that are lost.
``cost`` User-defined metric that will be used by the mesh routing algorithm. If the mesh were represented by a graph node, then cost would be the length or weight of the edges between nodes. When the routing algorithm determines how to pass network packets from one node to another, it will use this cost to determine an efficient path.
``nodecost`` Cost to a particular node on the mesh, and overrides whatever is set in ``cost``.
in foo.yml
.. code-block:: yaml
tcp-listeners:
- port: 2222
cost: 1.0
nodecost:
bar: 1.6
fish: 2.0
This means packets sent to `fish` have a cost of 2.0, whereas packets sent to `bar` have a cost of 1.6. If `haz` joined the mesh, it would get a cost of 1.0 since it's not in the nodecost map.
The costs on both ends of the connection must match.
For example, the ``tcp-peers`` configuration on ``fish`` must have a cost of ``2.0``, otherwise the connection will be refused.
in fish.yml
.. code-block:: yaml
tcp-peers:
- address: localhost:2222
cost: 2.0

=========================
Recptor out-of-the-box has the ability to support complicated networking environments including edge networks.
.. contents::
:local:
Consider the following environment:
.. image:: edge.png
:alt: Network diagram with netceptor peers to edge network
Configurable-Items
-------------------
Receptor encapsulates the concepts of `below-the-mesh` and `above-the-mesh` connections. Please refer to :doc:`tls` for a better understanding of these networking layers.
If a particular node in a network has higher than normal latency, we allow the users to define a finely-grained idle connection timeout value for any given Receptor node. This will help Receptor keep `below-the-mesh` tcp connections alive. Receptor will monitor backend connections for traffic and will timeout any connection that hasn't seen traffic for a period of time. Once the connection is dropped, a new connection is formed automatically.
If a connection timeout occurs, the users can expect to see a message like this in their receptor logs.
.. code-block:: text
DEBUG 2022/04/07 12:48:56 Sending initial connection message
ERROR 2022/04/07 12:48:56 Backend sending error read tcp 10.26.5 0.239:27199->10.102.21.131:35024: i/o **timeout**
To circumvent this scenario from happening, users can leverage the `maxidleconnectiontimeout` parameter in their configuration files.
`maxidleconnectiontimeout` A user-defined parameter in the configuration file that will set the `below-the-mesh` tcp connection timeout.
The configuration files for the diagram above are listed below.
foo.yml
.. code-block:: yaml
---
version: 2
node:
id: foo
maxidleconnectiontimeout: 60s
log-level:
level: Debug
tcp-listeners:
- port: 2222
bar.yml
.. code-block:: yaml
---
node:
id: bar
maxidleconnectiontimeout: 60s
log-level:
level: Debug
tcp-peers:
- address: localhost:2222
fish.yml
.. code-block:: yaml
---
node:
id: fish
maxidleconnectiontimeout: 60s
log-level:
level: Debug
tcp-peers:
- address: localhost:2222
*Note* - All Receptor nodes in the mesh must define a `maxidleconnectiontimeout` value, if this value is consumed on ANY node. The effective `maxidleconnectiontimeout` value is the minumum value between all the nodes in the mesh.

Firewall Rules
==============
Receptor has the ability to accept, drop, or reject traffic based on any combination of the following:
- ``FromNode``
- ``ToNode``
- ``FromService``
- ``ToService``
Firewall rules are added under the ``node`` entry in a Receptor configuration file:
.. code-block:: yaml
# Accepts everything
node:

User guide
*******************
This guide describes how to use receptor in multiple environments and uses the following terms:
.. glossary::
backend
A type of connection that receptor nodes can pass traffic over. Current backends include TCP, UDP and websockets.
backend peers
A node connected to another through receptor backends.
control node
A node running the receptor control service.
control service
A built-in service that usually runs under the name `control`. Used to report status and to launch and monitor work.
netceptor
The component of receptor that handles all networking functionality.
netceptor peers
A receptor node directly connected to another receptor node.
node
A single running instance of receptor.
node ID
An arbitrary string identifying a single node, analogous to an IP address.
receptor
The receptor application taken as a whole, which typically runs as a daemon.
receptorctl
A user-facing command line used to interact with receptor, typically over a Unix domain socket.
workceptor
The component of receptor that handles work units.

Interacting with nodes
======================
.. contents::
:local:
The ``control-service`` allows the user to issue commands like "status" or "work submit" to a receptor node.
foo.yml
.. code-block:: yaml
---
version: 2
node:
id: foo
log-level:
level: debug
tcp-listeners:
- port: 2222
control-services:
- service: control
filename: /tmp/foo.sock
bar.yml
.. code-block:: yaml
---
version: 2
node:
id: bar
log-level:
level: debug
tcp-peers:
- address: localhost:2222
control-services:
- service: control
If ``filename`` is set, receptor will create a unix domain socket. Use receptorctl to interact with the running receptor node via this domain socket (using "--socket"). The control service on `bar` does not have a ``filename`` set, but can be connected to using the "connect" command, as shown in the :ref:`connect_to_csv` section.
The "status" command will display helpful information about mesh, including known connections, routing tables, control services, and work types.
.. code-block:: console
$ receptorctl --socket /tmp/foo.sock status
Node ID: foo
Version: 0.9.8.dev57-0.git20210722.4d0310f

System Memory MiB: 15876

foo control Stream 2021-07-22 23:29:34 - -
bar control Stream 2021-07-22 23:32:35 - -
ReceptorControl
----------------
For a more programmatic way to interact with receptor nodes, use the ReceptorControl python class.
.. code-block:: python
from receptorctl import ReceptorControl
r = ReceptorControl("/tmp/foo.sock")
r.simple_command("work list")
.. _connect_to_csv:
Connect to control service
---------------------------
Use the "connect" command to connect to any receptor control service running on the mesh. From here, issue a series of commands and examine the output, without disconnecting.
.. code-block:: console
$ receptorctl --socket /tmp/foo.sock connect bar control
Receptor Control, node bar
This will result in a bridged connection between the local domain socket on `foo`, and the control service listener from `bar`.
One can also connect to the locally running control service in a similar manner
.. code-block:: console
$ receptorctl --socket /tmp/foo.sock connect localhost control
Receptor Control, node foo
"localhost" is a special keyword that tells receptor to connect to its own control-service. "localhost" can be used in all other control service commands that expect a node ID.
Once connected to a control service, one can issue commands like "status" or "work list" and get JSON-formatted responses back.
Keep in mind that a "work submit" command will require a payload. Type out the payload contents and press ctrl-D to send the EOF signal. The socket will then close and work will begin. See :ref:`user_guide/workceptor:workceptor` for more on submitting work via receptor.
.. _control_service_commands:
Control service commands
--------------------------
A ``control-service`` can accept commands in two formats; a space-delimited string or JSON. In some cases, JSON accepts arguments that are not supported in the string format and are marked with `json-only` in the table below.
String example:
.. code-block:: console
work submit bar echoint
JSON example:
.. code-block:: json
{
"command":"work",
"subcommand":"submit",
"node":"bar",
"worktype":"echoint"
}
For 2-word commands like ``work submit`` the first word is the "command", and the second word is the "subcommand"
The order of the parameters (from left to right) in the following table matter, as they are the order expected when issuing commands in string format.
.. list-table::
:widths: 15 25 50
:header-rows: 1
* - command
- required parameters
- optional parameters
* - status
-
-
* - reload
-
-
* - ping
- target
-
* - traceroute
- target
-
* - work list
-
- unitid
* - work submit
- node, worktype
- tlsclient (`json-only`), ttl (`json-only`)
* - work cancel
- unitid
-
* - work release
- unitid
-
* - work force-release
- unitid
-
* - work results
- unitid, startpos
-
The above table does not apply the receptorctl command-line tool. For the exact usage of the various receptorctl commands, type ``receptorctl --help``, or to see the help for a specific command, ``receptorctl work submit --help``.
Reload
-------
In general, changes to a receptor configuration file do not take effect until the receptor process is restarted.
Any action items related to receptor backend connections can be reloaded, without a receptor restart. These include:
.. code-block:: text
tcp-peers
tcp-listeners
ws-peers
ws-listeners
udp-peers
udp-listeners
local-only
Changes can include modifying, adding, or removing these items from the configuration file.
After saving the configuration file to disk, connect to a control service and issue a ``reload`` command for the new changes to take effect.
.. code-block:: console
receptorctl --socket /tmp/foo.sock reload
This command will cancel all running backend connections and sessions, re-parse the configuration file, and start the backends once more.
This allows users to add or remove backend connections without disrupting ongoing receptor operations. For example, sending payloads or getting work results will only momentarily pause after a reload and will resume once the connections are reestablished.

===============
.. contents::
:local:
Workceptor has the ability to launch Kubernetes pods to perform work.
foo.yml
.. code-block:: yaml
---
version: 2
node:
id: foo
log-level:
level: Debug
tcp-listeners:
port: 2222
control-services:
- service: control
filename: /tmp/foo.sock
work-kubernetes:
- worktype: kubeit
authmethod: kubeconfig
allowruntimeauth: true
allowruntimepod: true
allowruntimeparams: true
kubeitpod.yml
.. note::
You might need to set ``tcp-listeners``, ``tcp-peers``, or ``local-only`` before you can start the control service. See https://github.com/ansible/receptor/issues/518
.. code-block:: yaml
apiVersion: v1
kind: Pod
metadata:
generateName: myapp-pod-
labels:
app: myapp
spec:
containers:
- name: worker
image: busybox
command: ['sh', '-c', 'echo The Pod is running && sleep 6 && exit 0']
restartPolicy: Never
Note: at least one of the containers in the pod spec must be named "worker". This is the container that stdin is passed into, and that stdout is retrieved from.
First, we need the receptor control service running in order to be able to start a kubernetes work unit.
.. code-block:: sh
$ receptor -c foo.yml
DEBUG 2022/01/17 10:05:56 Listening on TCP [::]:2222
INFO 2022/01/17 10:05:56 Running control service control
INFO 2022/01/17 10:05:56 Initialization complete
Now we can submit a kubernetes work unit.
.. code-block:: bash
$ receptorctl --socket /tmp/foo.sock work submit kubeit --param secret_kube_config=@$HOME/.kube/config --param secret_kube_pod=@kubeitpod.yml --no-payload
Result: Job Started
Unit ID: FfpQ4zk2
``secret_kube_config`` The contents of kubeconfig file. The "@" tells receptorctl to read in a file name and pass the contents on.
``secret_kube_pod`` The contents of a pod definition. The "@" tells receptorctl to read in a file name and pass the contents on.
Runtime params
---------------
Additional parameters can be passed in when issuing a "work submit" command, using "--param" in receptorctl. These params must have the correct ``allowruntime*`` fields specified in the ``work-kubernetes`` definition.
.. list-table::
:widths: 25 50 25
:header-rows: 1
* - param
- description
- permission
* - kube_image
- container image to use
- allowruntimecommand
* - kube_command
- command container should run
- allowruntimecommand
* - kube_params
- parameters to pass into kube_command
- allowruntimeparams
* - kube_namespace
- kubernetes namespace to use
- allowruntimeauth
* - secret_kube_config
- kubeconfig to authenticate with
- allowruntimeauth
* - secret_kube_pod
- pod definition
- allowruntimepod
* - pod_pending_timeout
- allowed duration for pod to be Pending
- allowruntimeparams
``pod_pending_timeout`` is provided as a string, for example 1h20m30s or 30m10s.

===========
Receptor supports mutual TLS authentication and encryption for above and below the
mesh connections.
.. contents::
:local:
Configuring TLS
---------------
Add ``tls-servers`` and ``tls-clients`` definitions to Receptor configuration files.
``foo.yml``
.. code-block:: yaml
---
version: 2
node:
id: foo
log-level:
level: Debug
tls-servers:
- name: myserver
cert: /full/path/foo.crt
key: /full/path/foo.key
requireclientcert: true
clientcas: /full/path/ca.crt
tcp-listeners:
- port: 2222
tls: myserver
Defining ``tls-servers`` has no effect, but it can be referenced elsewhere in the Receptor configuration file.
In the preceding configuration snippet, ``tls`` in the ``tcp-listeners`` is set to use ``myserver``.
In general, ``tls-servers`` should be referenced anywhere Receptor is expecting an incoming connection, such as ``*-listeners`` backends or on the ``control-services``.
Similarly, ``tls-clients`` should be referenced anywhere Receptor is expecting to make an outgoing connection, such as ``*-peers`` backends or in ``receptorctl`` (the command-line client for Receptor).
``bar.yml``
.. code-block:: yaml
---
version: 2
node:
id: bar
log-level:
level: Debug
tls-clients:
- name: myclient
rootcas: /full/path/ca.crt
insecureskipverify: false
cert: /full/path/bar.crt
key: /full/path/bar.key
tcp-peers:
- address: localhost:2222
tls: myclient
``myclient`` is referenced in ``tcp-peers``. Once started, `foo` and `bar` will authenticate each other, and the connection will be fully encrypted.
Generating certs
-----------------
Receptor supports X.509 compliant certificates and provides a built-in tool to generate valid certificates.
Running and configuring Receptor with the ``cert-init``, ``cert-makereqs``, and ``cert-signreqs`` properties creates certificate authorities, make requests, and sign requests.
``makecerts.sh``
.. code-block:: bash
#!/bin/bash
mkdir -p certs
receptor --cert-init commonname="test CA" bits=2048 outcert=certs/ca.crt outkey=certs/ca.key
for node in foo bar; do
receptor --cert-makereq bits=2048 commonname="$node test cert" dnsname=localhost nodeid=$node outreq=certs/$node.csr outkey=certs/$node.key
receptor --cert-signreq req=certs/$node.csr cacert=certs/ca.crt cakey=certs/ca.key outcert=certs/$node.crt
done
The preceding script will create a CA, and for each node ``foo`` and ``bar``, create a certificate request and sign it with the CA.
These certificates and keys can then create ``tls-servers`` and ``tls-clients`` definitions in the Receptor configuration files.
Pinned certificates
--------------------
In a case where a TLS connection is only ever going to be made between two well-known nodes, it may be preferable to
require a specific certificate rather than accepting any certificate signed by a CA. Receptor supports certificate
pinning for this purpose. Here is an example of a pinned certificate configuration:
.. code-block:: yaml
---
version: 2
node:
id: foo
tls-servers:
- name: myserver
cert: /full/path/foo.crt
key: /full/path/foo.key
requireclientcert: true
clientcas: /full/path/ca.crt
pinnedclientcert:
- E6:9B:98:A7:A5:DB:17:D6:E4:2C:DE:76:45:42:A8:79:A3:0A:C5:6D:10:42:7A:6A:C4:54:57:83:F1:0F:E2:95
tcp-listeners:
- port: 2222
tls: myserver
Certificate pinning is an added requirement, and does not eliminate the need to meet other stated requirements. In the above example, the client certificate must both be signed by a CA in the `ca.crt` bundle, and also have the listed fingerprint. Multiple fingerprints may be specified, in which case a certificate matching any one of them will be accepted.
To find the fingerprint of a given certificate, use the following OpenSSL command:
.. code-block:: bash
openssl x509 -in my-cert.pem -noout -fingerprint -sha256
SHA256 and SHA512 fingerprints are supported. SHA1 fingerprints are not supported due to the insecurity of the SHA1 algorithm.
Above the mesh TLS
-------------------
Below-the-mesh TLS deals with connections that are being made to an IP address or DNS name, and so it can use normal X.509 certificates which include DNS names or IP addresses in their ``subjectAltName`` field.
Above-the-mesh TLS deals with connections that use Receptor node IDs as endpoint addresses, which require generating certificates that include Receptor node IDs as names in the ``subjectAltName`` extension.
You can use the ``otherName`` field of ``subjectAltName`` to specify Receptor node IDs.
The ``otherName`` field accepts arbitrary names of any type, and includes an ISO Object Identifier (OID) that defines what type of name this is, followed by arbitrary data that is meaningful for that type.
Red Hat has its own OID namespace, which is controlled by RHANANA, the Red Hat Assigned Names And Number Authority.
Receptor has an assignment within the overall Red Hat namespace.
If you use TLS authentication in your mesh, the certificates OIDs (1.3.6.1.4.1.2312.19.1) will be verified against the `node.id` specified in the configuration file. If there is no match, the Receptor binary will hard exit. To avoid this check, visit the `Skip Certificate Validation`_ section for more details.
Skip certificate validation
----------------------------
You can turn off certificate validation by adding a `skipreceptornamescheck` key-value pair to your configuration. Depending on the specifics of your environment(s), you may need to add the ``skipreceptornamescheck`` key-value pair to the configuration file for `tls-server`, `tls-config`, or both.
The default behavior for this option is `false` which means that the certificate's OIDs will be verified against the node ID.

==========
.. contents::
:local:
Workceptor is a component of receptor that handles units of work.
``work-commands`` defines a type of work that can run on the node.
foo.yml
.. code-block:: yaml
---
version: 2
node:
id: foo
log-level:
level: Debug
tcp-listeners:
- port: 2222
control-services:
- service: control
filename: /tmp/foo.sock
work-commands:
- workType: echoint
command: bash
params: "-c \"for i in {1..5}; do echo $i; sleep 1; done\""
bar.yml
.. code-block:: yaml
---
version: 2
node:
id: bar
log-level:
level: Debug
tcp-peer:
address: localhost:2222
control-services:
- service: control
work-commands:
- worktype: echoint
command: bash
params: "-c \"for i in {1..10}; do echo $i; sleep 1; done\""
- workType: echopayload
command: bash
params: "-c \"while read -r line; do echo ${line^^}; sleep 3; done\""
Configuring work commands
--------------------------
``worktype`` User-defined name to give this work definition
``command`` The executable that is invoked when running this work
``params`` Command-line options passed to this executable
Local work
-----------
Start the work by connecting to the ``control-services`` and issuing a "work submit" command
.. code-block:: bash
$ receptorctl --socket /tmp/foo.sock work submit echoint --no-payload
Result: Job Started
Unit ID: t1BlAB18
Receptor started an instance of this work type, and labeled it with a unique "Unit ID"
Work results
-------------
Use the "Unit ID" to get work results
.. code-block:: bash
receptorctl --socket /tmp/foo.sock work results t1BlAB18
1
2
3
4
5
6
7
8
9
10
Remote work
------------
Although connected to `foo`, by providing the "--node" option the work can be started on node `bar`.
The work type must be defined on the node it is intended to run on, e.g. `bar` must have a ``work-command`` called "echoint", in this case.
.. code-block:: bash
$ receptorctl --socket /tmp/foo.sock work submit echoint --node bar --no-payload
Result: Job Started
Unit ID: 87Vwqb6A
Remote work submission ultimately results in two work units running at the same time; a local work unit and the remote work unit. These two units have their own Unit IDs. The local work unit's goal is to monitor and stream results back from the running remote work unit.
Sequence of events for remote work submission
- `foo` starts a local work unit of work type "remote". This is a special work type that is built into receptor.
- This work unit attempts to connect to `bar`'s control service and issue a "work submit echoint" command. From `bar`'s perspective, this is the exact same operation as if a user connected to `bar` directly and issued a work submit command. `bar` is not aware that `foo` is the one that issued the command.
- Once submitted, `foo` will stream work results back to itself and store it on disk. It also periodically gets the ``work status`` of the work running on `bar`. Status includes information about the work state and the stdout size.
- `foo` continues streaming stdout results until the size stored on disk matches the StdoutSize reported in `bar`'s status.
.. _work_payload:
Payload
--------
in `bar.yml`
.. code-block:: yaml
- workType: echopayload
command: bash
params: "-c \"while read -r line; do echo ${line^^}; sleep 5; done\""
Here the bash command expects to read a line from stdin, echo the line in all uppercase letters, and sleep for 3 seconds.
Payloads can be passed into receptor using the "--payload" option.
.. code-block:: bash
$ echo -e "hi\ni am foo\nwhat is your name" | receptorctl --socket /tmp/foo.sock work submit echopayload --node bar --payload - -f
HI
I AM FOO
WHAT IS YOUR NAME
"--payload -" means the payload should be whatever the stdin is, which is piped in from the "echo -e ..." command.
Note: "-f" instructs receptorctl to follow the work unit immediately, i.e. stream results to stdout. One could also use "work results" to stream the results.
Runtime Parameters
-------------------
Work commands can be configured to allow parameters to be passed to commands when work is submitted:
.. code-block:: yaml
work-commands:
- workType: listcontents
command: ls
allowruntimeparams: true
The ``allowruntimeparams`` option will allow parameters to be passed to the work command by the
client submitting the work. The contents of a specific directory can be listed by passing the paths
to the receptor command as positional arguments immediately after the ``workType``:
.. code-block:: bash
receptorctl --socket /tmp/foo.sock work submit --node bar --no-payload -f listcontents /root/ /bin/
/bin/:
bash
sh
/root/:
helloworld.sh
Passing options or flags to the work command needs to be done using the ``--param`` parameter to
extend the ``params`` work command setting. The ``--all`` flag can be passed to the work command this way:
.. code-block:: bash
receptorctl --socket /tmp/foo.sock work submit --node bar --no-payload -f --param params='--all' listcontents /root/
.
..
.bash_logout
.bash_profile
.bashrc
.cache
helloworld.sh
Work list
----------
"work list" returns information about all work units that have ran on this receptor node. The following shows two work units, ``12L8s8h2`` and ``T0oN0CAp``
.. code-block:: bash
$ receptorctl --socket /tmp/foo.sock work list
{'12L8s8h2': {'Detail': 'exit status 0',
'ExtraData': None,
'State': 2,
'StateName': 'Succeeded',
'StdoutSize': 21,
'WorkType': 'echoint'},
'T0oN0CAp': {'Detail': 'Running: PID 1700818',
'ExtraData': {'Expiration': '0001-01-01T00:00:00Z',
'LocalCancelled': False,
'LocalReleased': False,
'RemoteNode': 'bar',
'RemoteParams': {},
'RemoteStarted': True,
'RemoteUnitID': 'ATDzdViR',
'RemoteWorkType': 'echoint',
'TLSClient': ''},
'State': 1,
'StateName': 'Running',
'StdoutSize': 4,
'WorkType': 'remote'},
Notice that ``T0oN0CAp`` was a remote work submission, therefore its work type is "remote". On `bar` there is a local unit ``ATDzdViR``, with the "echoint" work type.
Work cancel
------------
Cancel will stop any running work unit. Upon canceling a "remote" work unit, the local node will attempt to connect to the remote node's control service and issue a work cancel. If the remote node is down, receptor will periodically attempt to connect to the remote node to do the cancellation.
Work release
-------------
Release will cancel the work and then delete files on disk associated with that work unit. For remote work submission, release will attempt to delete files both locally and on the remote machine. Like work cancel, the release can be pending if the remote node is down. In that situation, the local files will remain on disk until the remote node can be contacted.
Work force-release
--------------------
It might be preferable to force a release, using the ``work force-release`` command. This will do a one-time attempt to connect to the remote node and issue a work release there. After this one attempt, it will then proceed to delete all local files associated with the work unit.
States
---------
A unit of work can be in Pending, Running, Succeeded, or Failed state
For local work, transitioning from Pending to Running occurs the moment the ``command`` executable is started
For remote work, transitioning from Pending to Running occurs when the status reported from the remote node has a Running state.
Signed work
------------
Remote work submissions can be digitally signed by the sender. The target node will verify the signature of the work command before starting the work unit.
A *single* pair of RSA public and private keys is created offline and distributed to the nodes. Distribute the public key (PKIX format) to any node that should receive work. Distribute the private key (PKCS1 format) to any node that needs authority to submit work.
The following commands can be used to create keys for signing work:
.. code-block:: bash
openssl genrsa -out signworkprivate.pem 2048
openssl rsa -in signworkprivate.pem -pubout -out signworkpublic.pem
in `bar.yml`
.. code-block:: yaml
# PKIX
work-verification:
publickey: /full/path/signworkpublic.pem
- workType: echopayload
command: bash
params: "-c \"while read -r line; do echo ${line^^}; sleep 5; done\""
verifysignature: true
in `foo.yml`
.. code-block:: yaml
# PKCS1
work-signing:
privatekey: /full/path/signworkprivate.pem
tokenexpiration: 30m
Tokenexpiration determines how long a the signature is valid for. This expiration directly corresponds to the "expiresAt" field in the generated JSON web token. Valid units include "h" and "m", e.g. 1h30m for one hour and 30 minutes.
Use the "--signwork" parameter to sign the work.
.. code-block:: bash
$ receptorctl --socket /tmp/foo.sock work submit echoint --node bar --no-payload --signwork
Units on disk
--------------
Netceptor, the main component of receptor that handles mesh connectivity and traffic, operates entirely in memory. That is, it does not store any state information on disk. However, Workceptor functionality is designed to be persistent across receptor restarts. Work units might be running commands that could take hours to complete, and as such needs to store some relevant information on disk in case the receptor process restarts.
By default receptor stores data under ``/tmp/receptor`` but can be changed by setting the ``datadir`` param under the ``node`` action in the config file.
For a given work unit, receptor will store files in ``{datadir}/{nodeID}/{unitID}/``.
Here is the receptor directory tree after running ``work submit echopayload`` described in :ref:`work_payload`.
.. code-block:: bash
$ tree /tmp/receptor
/tmp/receptor
├── bar
│ └── NImim5WA
│ ├── status
│ ├── status.lock
│ ├── stdin
│ └── stdout
└── foo
└── BsAjS4wi
├── status
├── status.lock
├── stdin
└── stdout
The main purpose of work unit ``BsAjS4wi`` on `foo` is to copy stdin, stdout, and status from ``NImim5WA`` on `bar` back to its own working directory.
``stdin`` is a copy of the submitted payload. The contents of this file is the same on both the local (`foo`) and remote (`bar`) machines.
.. code-block:: bash
$ cat /tmp/receptor/bar/NImim5WA/stdin
hi
i am foo
what is your name
``stdout`` contains the work unit results; the stdout of the command execution. It will also be the same on both the local node and remote node.
.. code-block:: bash
$ cat /tmp/receptor/bar/NImim5WA/stdout
HI
I AM FOO
WHAT IS YOUR NAME
``status`` contains additional information related to the work unit. The contents of status are different on `foo` and `bar`.
.. code-block:: bash
$ cat /tmp/receptor/bar/NImim5WA/stdout
{
"State":2,
"Detail":"exit status 0",
"StdoutSize":30,
"WorkType":"echopayload",
"ExtraData":null
}
.. code-block:: text
$ cat /tmp/receptor/foo/BsAjS4wi/stdout
{
"State":2,
"Detail":"exit status 0",
"StdoutSize":30,
"WorkType":"remote",
"ExtraData":{
"RemoteNode":"bar",
"RemoteWorkType":"echopayload",
"RemoteParams":{},
"RemoteUnitID":"NImim5WA",
"RemoteStarted":true,
"LocalCancelled":false,
"LocalReleased":false,

A decorator intended to be used by Receptor plugins in conjunction with
entrypoints typically defined in your setup.py file::
entry_points={
'receptor.worker':
'your_package_name = your_package_name.your_module',
}
``your_package_name.your_module`` should then contain a function decorated with
``plugin_export`` as such::
@receptor.plugin_export(payload_type=receptor.BYTES_PAYLOAD):
def execute(message, config, result_queue):
result_queue.put("My plugin ran!")
You can then send messages to this plugin across the Receptor mesh with the directive
``your_package_name:execute``
Depending on what kind of data you expect to receive you can select from one
of 3 different incoming payload types. This determines the incoming type of the
``message`` data type:
* BYTES_PAYLOAD: This will give you literal python bytes that you can then read
and interpret.
* BUFFER_PAYLOAD: This will send you a buffer that you can read(). This buffer
will be automatically closed and its contents discarded when your plugin returns.
* FILE_PAYLOAD: This will return you a file path that you can open() or manage
in any way you see fit. It will be automatically removed after your plugin returns.
For more information about developing plugins see :ref:`plugins`.

Receptorctl is a front-end CLI and importable Python library that interacts with Receptor over its control socket interface.
## Setting up nox
This project includes a `nox` configuration to automate tests, checks, and other functions in a reproducible way using isolated environments.
Before you submit a PR, you should install `nox` and verify your changes.
> To run `make receptorctl-lint` and `receptorctl-test` from the repository root, you must first install `nox`.
1. Install `nox` using `python3 -m pip install nox` or your distribution's package manager.
2. Run `nox --list` from the `receptorctl` directory to view available sessions.
You can run `nox` with no arguments to execute all checks and tests.
Alternatively, you can run only certain tasks as outlined in the following sections.
> By default nox sessions install pinned dependencies from `pyproject.toml`.
## Checking changes to Receptorctl
Run the following `nox` sessions to check for code style and formatting issues:
* Run all checks.
```bash
nox -s lint
```
* Check code style.
```bash
nox -s check_style
```
* Check formatting.
```bash
nox -s check_format
```
* Format code if the check fails.
```bash
nox -s format
```
## Running Receptorctl tests
Run the following `nox` sessions to test Receptorctl changes:
* Run tests against the complete matrix of Python versions.
```bash
nox -s tests
```
* Run tests against a specific Python version.
```bash
# For example, this command tests Receptorctl against Python 3.12.
nox -s tests-3.12
```
## Updating dependencies
Update dependencies using `uv` as follows:
1. Add or modify packages in `pyproject.toml` under `dependencies` or `optional-dependencies`.
2. Regenerate the lock file from the `receptorctl` directory:
```bash
uv lock
```
> The `uv.lock` file pins all dependencies with cryptographic hashes for reproducible installs.
> Commit the updated `uv.lock` file along with your `pyproject.toml` changes.

All test files and test tools can be found on this directory.
```java
.
|-- artifacts : "receptor-tester.sh builds output"
|-- environments : "Controlled environments for testing"
| |-- container : "Containerfile recipe"
| `-- vagrant : "VM recipe"
`-- functional : "Functional test files"
|-- cli
|-- lib
`-- mesh
```
## Tests
1. Functional tests and correspondent docs can be found here: [./functional/README.md](./functional/README.md)
## Tools
There are two parts of Receptor tools. Each one is used for different scenarios.
Requirements:
- podman
- make
### receptor-tester
All features will be showed on `help` argument:
```bash
./receptor-tester.sh help
# Command list:
# list-dirs - list all available tests directories
# list-files - list all available tests files
# run - run a specific test
# run-all - run all tests. Returns 0 if pass
# help - Displays this help text
```
List all available tests:
```bash
# list all available tests directories
./receptor-tester.sh list-dirs
# ./functional/mesh
# ./functional/cli
# ./functional/lib/utils
# List all available tests files
./receptor-tester.sh list-files
# ./functional/mesh/mesh_test.go
# ./functional/mesh/work_test.go
# ./functional/mesh/tls_test.go
# ./functional/cli/cli_test.go
# ./functional/lib/utils/utils_test.go
```
Run tests:
```bash
# run a specific test
./receptor-tester.sh run ./functional/cli/cli_test.go
# run all tests
./receptor-tester.sh run-all
```
### Makefile
Build artifacts (receptor and receptorctl) based on latest source code.
The container recipe used can be found at `environments/container`.
```bash
# Build artifacts
make artifacts
```
Container commands can be used in conjunction with `make artifacts` or isolated to run ad-hoc commands inside a controlled environment.
```bash
# Rebuild container image used
# by `make artifacts`
make container-image # OR
make container-image-base
# Jump into a container created from
# the same container image used by
# `make artifacts`
make container-shell-base
```
If you're using Windows or macOS, the following commands can be useful to create a virtual machine and play aroung with containers inside there.
Requirements:
- vagrant
```bash
# Creates a Vagrant VM
make vm # OR
make vm-create
# SSH into VM
make vm-shell
# Destroy VM
make vm-destroy
# Reapply Ansible playbook into VM
make vm-provision
```

This document will serve as a reference for how the upstream receptor tests
work. This will cover both high level and low level details of how the tests
are setup and run including the assumptions being made and the best way to
add tests going forward.
## Test Dependencies
The following are needed to run the integration tests:
* `receptor` must be in your path, I have symlinked `~/bin/receptor` to the
`receptor` binary in my repo so my current dev build is always in my path.
* `lsof` is used to check if processes are bound to the right ports
* In order to run the kubernetes integration tests you must have a running
kubernetes and a `~/.kube/config` that has access to the default namespace
as the kubernetes tests will expect they can run there. To skip kubernetes
tests set `SKIP_KUBE=1` in your environment.
* In order to run the receptorctl tests you must have python3, virtualenv, and
pip installed. The `receptorctl-tests` make target will setup a virtualenv
for the tests.
* `openssl` must be installed on the system in order for the cli tests to run
properly.
## CLI Tests
The cli tests are found in `functional/cli/cli_test.go`. The intention for
these tests is to validate that the cli handles flags correctly. For example
the flags that take bools correctly interpret their input as bools and those
that take maps are able to take a string of json and convert it to a map.
These tests are fairly simple because of this and wont be a large focus of this
document.
## Mesh Tests
The mesh tests are found in `functional/mesh/`. These tests are the most
complicated and provide the most value. They test that the receptor mesh works
as expected, nodes can connect to eachother, route packets, start work, etc. In
many cases this is where tests should be added.
Each test launches its own mesh by using yaml or the in language specification
and calling a helper function to build a mesh based on that mesh definition.
These meshes can be built in 3 ways:
* As part of the test process (LibMesh and LibNode)
* As new processes using the cli (CliMesh and CliNode)
* As containers using docker or podman (ContainerMesh and ContainerNode)
In most cases the CliMesh is appropriate and almost all existing tests use it.
The LibMesh was made to allow for testing receptor as an imported library into
other golang projects and was used to find some bugs, however at this point it
is unclear when/if receptor will be used in this way. The LibNodes also dont
support all receptor features as the mesh building code must manually import
the right functions and call them to setup the receptor node. For these 2
reasons the LibMesh should probably be avoided unless you know what you want to
test is using receptor as a importable library. Finally the ContainerMeshes are
essentially CliMeshes wrapped in a container. The initial intention was to use
these to simulate various network conditions using tc (which is supported in
the mesh definition and building for ContainerMeshes), and I have used them
for that purpose in somewhat manual ways, but no existing automation uses them.
One thing to note is all nodes in the mesh for our test suite are always of the
same type, you cannot mix CLINodes with LibNodes, I decided to keep that
separation for simplicity however in practice there's no reason this cant be
done.
Another thing to consider is when running tests in parallel we make some
assumptions to make this easier to reason about so nodes dont try use
overlapping ports.
LibNodes select their own ports by asking the OS to give them an unused port.
ContainerNodes and CLINodes use a shared port pool and reserve ports to use.
However it is possible from the time it is reserved to the time the process
starts that another process could grab that port, we are unable to prevent
this. The most likely scenario that could cause this is running LibNodes and
CLI/ContainerNodes at the same time. To reduce the chance of this we only
run 1 test binary at once, however the various tests in that binary can run
in parallel.
Mesh logs are saved to a unique directory in `/tmp/receptor-tests/` based on
the name of the test. All the config files required to start the nodes are
also stored in this directory, this makes it easy to navigate to and debug
nodes when a test fails.
## Automation
The receptor tests run in github actions and must pass before merging a PR.
There is a make `ci` target that does linting, building, and runs the receptor
tests as well as the receptorctl tests, this is what github actions runs.
The github actions run in a docker container that is built nightly and uploaded
to the github image registry. The tests also start a minikube k8s cluster for
testing the k8s integration. If the tests fail, we collect all the node logs
for each test mesh and archive it however we do not have a way to generate
a junit test report and archive that.

This example creates two receptor nodes, called `arceus` and `celebi`.
## Diagram
The `ctl.sh` script (equivalent to `receptorctl`) sends the message to Celebi through an unix domain socket `socks/celebi.sock`, then Celebi forwards that message to Arceus through the docker-compose network.
## Commands
```bash
# Build and run
docker-compose up -d
# Destroy and cleanup
docker-compose down
rm -rf ./socks/
# Run commands on receptorctl
./ctl.sh
# Examples
./ctl.sh ping celebi
./ctl.sh ping arceus
```
## Config files
Celebi socket is exposed:
Full Celebi config file can be found here: [configs/celebi.yaml](configs/celebi.yaml)
```yaml
...
- control-service:
service: control
filename: /socks/celebi.sock
```
Arceus port is exposed:
Full Arceus config file can be found here: [configs/arceus.yaml](configs/arceus.yaml)
```yaml
...
- tcp-listener:
port: 2223
...
```
