@Marvin is it possible to clear docker containers that are created by flow runs and deployed via docker image?

It looks like the documentation and GitHub issues don't provide a direct solution for clearing Docker containers that are created by flow runs and deployed via a Docker image in Prefect. However, you can manage and clean up these containers by integrating Docker CLI commands or using Docker SDK in your flows to programmatically remove containers once the flow runs are completed. Here is a general approach using Docker SDK in Python: 1. Install Docker SDK for Python:

sh
    pip install docker

2. Add cleanup tasks to your flow: In your Prefect flow, you can add tasks to list and remove Docker containers that match certain criteria.

python
    from prefect import task, Flow
    import docker

    @task
    def remove_docker_containers():
        client = docker.from_env()
        containers = client.containers.list(filters={"ancestor": "your-docker-image"})
        for container in containers:
            container.stop()
            container.remove()

    @task
    def your_flow_task():
        # Your flow logic here
        pass

    with Flow("Docker Cleanup Flow") as flow:
        result = your_flow_task()
        cleanup = remove_docker_containers(upstream_tasks=[result])

    flow.run()

This script will stop and remove all containers that were created from the specified Docker image once the flow's main task completes. Adjust the filter criteria as needed to match your use case. For more information on Prefect flows and tasks, please see Prefect Documentation. For more details on Docker SDK for Python, refer to Docker SDK Documentation. By managing Docker containers in this way, you can ensure that resources are cleaned up appropriately after each flow run.
