socket.gethostname() method for python docker lib returns hostname() for old

[Valleymu]

I have this method running in docker container

import docker

def register_container():
    client = docker.from_env(version="auto", timeout=30)
    container = client.containers.get(socket.gethostname())

When watchtower updates my image and restarts container I get this error:

2025-01-20 01:24:48 docker.errors.NotFound: 404 Client Error for http+docker://localhost/v1.47/containers/4658ae62f206/json: Not Found ("No such container: 4658ae62f206")

4658ae62f206 is an old container id, looks like socket returns old hostname

Is there a way to fix it? I'm attempting to get container ID

After restart environment variable HOSTNAME is also old one

Hi, I think this you are in the wrong project. I'm going to close this issue now as it does not refer to any functionality that this library supports.
