Get live stdout of a running container

Hi,

I need to run a long time command in a container and print the stdout/stderr in live.

From what I have done so far I have to wait the end of the execution before being able to see the output logs.

For example, in the above code, I would like to be able to see "hello" before waiting the end of the 20secs:

import docker
client = docker.from_env()
container = client.containers.run('python:alpine', '''python -c "
                                import time; 
                                print('hello'); 
                                time.sleep(20); 
                                print('OK')"''',
                               detach=True, remove=True)

Many thanks for your help.

Start with the containers.run call in the issue and reproduce the detached-container example to observe when stdout and stderr become available. Trace the existing container output or logging path, then make live output available before the command exits; the example should show "hello" before the 20-second delay and "OK" afterward.
