Asynchronous Python client for Python Portainer.

## About

This is an asynchronous Python client for the [Portainer API](https://docs.portainer.io/api-docs/). It is designed to be used with the [Portainer](https://www.portainer.io/) container management tool.
This package is a wrapper around the Portainer API, which allows you to interact with Portainer programmatically.

In it's current stage it's still in development and not all endpoints are implemented yet.

## Installation

```bash
pip install pyportainer
```

### Example

```python
import asyncio

from pyportainer import Portainer


async def main() -> None:
    """Run the example."""
    async with Portainer(
        api_url="http://localhost:9000",
        api_key="YOUR_API_KEY",
    ) as portainer:
        endpoints = await portainer.get_endpoints()
        print("Portainer Endpoints:", endpoints)


if __name__ == "__main__":
    asyncio.run(main())
```

More examples can be found in the [examples folder](./examples/).

## Image Update Watcher

`pyportainer` includes a built-in background watcher that continuously monitors your Docker containers for available image updates. It polls Portainer at a configurable interval, checks each running container's local image digest against the registry, and exposes the results for easy consumption.

### Basic usage

```python
import asyncio
from datetime import timedelta

from pyportainer import Portainer, PortainerImageWatcher


async def main() -> None:
    async with Portainer(
        api_url="http://localhost:9000",
        api_key="YOUR_API_KEY",
    ) as portainer:
        watcher = PortainerImageWatcher(
            portainer,
            interval=timedelta(hours=6),
        )

        watcher.start()

        await asyncio.sleep(30)  # Let the first check complete

        for (endpoint_id, container_id), result in watcher.results.items():
            if result.status and result.status.update_available:
                print(f"Update available for container {container_id} on endpoint {endpoint_id}")

        watcher.stop()


if __name__ == "__main__":
    asyncio.run(main())
```

### Configuration

| Parameter     | Type          | Default  | Description                                       |
| ------------- | ------------- | -------- | ------------------------------------------------- |
| `portainer`   | `Portainer`   | —        | The Portainer client instance                     |
| `endpoint_id` | `int \| None` | `None`   | Endpoint to monitor. `None` watches all endpoints |
| `interval`    | `timedelta`   | 12 hours | How often to poll for updates                     |
| `debug`       | `bool`        | `False`  | Enable debug-level logging                        |

### Results

`watcher.results` returns a dictionary keyed by `(endpoint_id, container_id)` tuples. Each value is a `PortainerImageWatcherResult` containing:

- `endpoint_id` — the endpoint the container belongs to
- `container_id` — the container ID
- `status` — a `PortainerImageUpdateStatus` with:
  - `update_available` (`bool`) — whether a newer image is available in the registry
  - `local_digest` (`str | None`) — digest of the locally running image
  - `registry_digest` (`str | None`) — digest of the latest image in the registry

You can also inspect `watcher.last_check` to get the Unix timestamp of the most recent completed poll, or update `watcher.interval` at runtime to change the polling frequency.

### Callbacks

Register a callback to be notified automatically after each poll cycle rather than polling `watcher.results` yourself. Both sync and async callables are supported:

```python
from pyportainer.watcher import PortainerImageWatcherResult


async def on_result(result: PortainerImageWatcherResult) -> None:
    if result.status and result.status.update_available:
        print(f"Update available for {result.container_id}")


watcher.register_callback(on_result)
# Later, to remove it:
watcher.unregister_callback(on_result)
```

Callbacks receive one `PortainerImageWatcherResult` per container per cycle. Exceptions raised inside a callback are logged and do not stop the watcher.

## Event Listener

`pyportainer` also includes a `PortainerEventListener` that maintains a streaming connection to the Docker events endpoint. Unlike the image watcher, it reacts in real time as events occur; container starts, stops, crashes, image pulls, and more.

### Basic usage

```python
import asyncio

from pyportainer import Portainer, PortainerEventListener
from pyportainer.listener import PortainerEventListenerResult


async def on_event(result: PortainerEventListenerResult) -> None:
    print(f"[endpoint {result.endpoint_id}] {result.event.type} {result.event.action}")


async def main() -> None:
    async with Portainer(
        api_url="http://localhost:9000",
        api_key="YOUR_API_KEY",
    ) as portainer:
        listener = PortainerEventListener(
            portainer,
            event_types=["container"],  # only container events
        )
        listener.register_callback(on_event)
        listener.start()

        await asyncio.sleep(60)

        listener.stop()


if __name__ == "__main__":
    asyncio.run(main())
```

### Configuration

| Parameter            | Type                | Default   | Description                                                     |
| -------------------- | ------------------- | --------- | --------------------------------------------------------------- |
| `portainer`          | `Portainer`         | —         | The Portainer client instance                                   |
| `endpoint_id`        | `int \| None`       | `None`    | Endpoint to listen to. `None` listens to all endpoints          |
| `event_types`        | `list[str] \| None` | `None`    | Docker event types to filter on. `None` means all types         |
| `reconnect_interval` | `timedelta`         | 5 seconds | How long to wait before reconnecting after a dropped connection |
| `debug`              | `bool`              | `False`   | Enable debug-level logging                                      |

Connections are automatically re-established after transient errors. Authentication errors stop the listener for the affected endpoint without retrying.

### Querying past events

Use `get_recent_events` to fetch a bounded list of past events without starting a persistent listener:

```python
from datetime import UTC, datetime, timedelta

events = await portainer.get_recent_events(
    endpoint_id=1,
    since=datetime.now(UTC) - timedelta(hours=1),
)
```

Or stream events in real time directly with `get_events`:

```python
async for event in portainer.get_events(endpoint_id=1, filters={"type": ["container"]}):
    print(event.action, event.actor.id)
```

## Contributing

This is an active open-source project. We are always open to people who want to
use the code or contribute to it.

We've set up a separate document for our
[contribution guidelines](CONTRIBUTING.md).

Thank you for being involved! :heart_eyes:

## Setting up development environment

The simplest way to begin is by utilizing the [Dev Container][devcontainer]
feature of Visual Studio Code or by opening a CodeSpace directly on GitHub.
By clicking the button below you immediately start a Dev Container in Visual Studio Code.

[![Open in Dev Containers][devcontainer-shield]][devcontainer]

This Python project relies on [UV][poetry] as its dependency manager,
providing comprehensive management and control over project dependencies.

### Installation

Install all packages, including all development requirements:

```bash
uv sync --all-groups && pre-commit install
```

_UV creates by default an virtual environment where it installs all necessary pip packages_.

### Pre-commit

This repository uses the [pre-commit][pre-commit] framework, all changes
are linted and tested with each commit. To setup the pre-commit check, run:

```bash
uv run pre-commit install
```

And to run all checks and tests manually, use the following command:

```bash
uv run pre-commit run --all-files
```

### Testing

It uses [pytest](https://docs.pytest.org/en/stable/) as the test framework. To run the tests:

```bash
uv run pytest
```

To update the [syrupy](https://github.com/tophat/syrupy) snapshot tests:

```bash
uv run pytest --snapshot-update
```
