Description

When I run my docker image normally like so

docker run -v ..... {DOCKER_IMAGE}

I get my log/stdout in the terminal as expected. But running like so:

docker_client = docker.from_env() docker_client.containers.run(DOCKER_IMAGE, None, environment=[f'foo={self.profile}'], volumes={...,}, auto_remove=True, stderr=True, stdout=True) # No stdout

Seems to suppress output. How can I get the log output while it's running? Can I stream the docker container run?

Right now I'm doing this:

docker_client.containers.run(DOCKER_IMAGE, None, environment=[f'foo={self.profile}'],  volumes={...,}, auto_remove=True, stderr=True, stdout=True, detach=True) 
for line in container.logs(stream=True):
       logger.info(line.strip().decode('utf8'))

But the problem is that this removes stdout and stderr, it'll all just be info.

Research direction

Start with the Python API entry points shown in the report: docker.from_env(), containers.run(), and container.logs(stream=True). Compare the behavior of attached and detached runs, including stderr=True and stdout=True. Done means container output can be streamed while retaining the distinction between stdout and stderr.
