docker-py: How to get exit code returned by process running inside container?
My python script uses docker-py to launch a docker container as follows:
client = docker.from_env()
result = client.containers.run(
image="my-prog-image:latest",
command=["/etc/my-prog/configs.ini"],
auto_remove=True,
network_mode="host",
)
As documented docker-py: containers, the client.containers.run(...) method returns container. How can I retrieve exit code returned by my-prog running inside container?

result.wait() should wait for the container to run to completion, then return its exit code.
However, you'll probably hit some trouble with this since you specify auto_remove=True but do not specify detach=True. run() without detach=True will run the container to completion, then the auto_remove=True option will delete the container, and at that point the status code doesn't exist any more. You might split these steps up explicitly:
client = docker.from_env()
container = client.containers.run(
image="my-prog-image:latest",
command=["/etc/my-prog/configs.ini"],
detach=True,
)
result = container.wait()
container.remove()
(In Docker CLI terms, you've done docker run --rm ... and then are trying to find the container's result with docker ps -a, but the container is gone; I suggest changing it to docker run -d ... without --rm, checking the docker ps output, and then manually docker rm the container. Actually, there's even a docker wait CLI command but it's rarely used.)
