@Marvin if in my flow.py file I run a container and then I want to tail all the logs that are from the container I run in the flow.py how to make sure that all logs are tailed (streamed) and not cut off

It appears that Prefect's current implementation has difficulty streaming logs directly from Docker containers within a flow. Specifically, the

get_docker_container_logs

function might face issues due to how the output is decoded, as discussed in this GitHub issue. Based on the available information, here are a few suggestions you might consider: 1. Manually Configure Log Streaming: You can implement a custom function to stream logs from the container using Docker's Python SDK. Here’s a simplified example:

python
   import docker
   from prefect import task, Flow
   import time
   
   @task
   def run_container_and_stream_logs(image_name: str):
       client = docker.from_env()
       container = client.containers.run(image_name, detach=True)
       
       for log in container.logs(stream=True):
           print(log.decode('utf-8'))
   
   with Flow("docker-log-streaming") as flow:
       run_container_and_stream_logs("your-docker-image")
   
   flow.run()

2. Logging into Files: A workaround could be directing container logs to files and then reading those files within your flow tasks. 3. Contributions and PRs: Since there is interest in supporting this feature, consider contributing to Prefect's repository to enhance the

get_docker_container_logs

function for better handling of log streaming. For optimal results, keep an eye on any updates to the relevant issues or community threads. Here’s an important issue for reference: GitHub Issue #12939.
