Error while removing network: network <netwok_name> id <network_id> has active endpoints

[sydevinfra]

Description

Sometimes a network fails to be removed with the following error :

$ docker network rm s_web
Error response from daemon: error while removing network: network s_web id 6b63ee4e95208b6869d072ef45803dbd2b9a517b03b1679c586814a66552f037 has active endpoints

Running docker inspect s_web shows no containers attached. In fact there are no containers at all.

$ docker network inspect s_web

        }
    }
]

$ docker container ls -a
CONTAINER ID   IMAGE     COMMAND   CREATED   STATUS    PORTS     NAMES

The only way to delete the network is to restart the docker service and then run the delete command again. This error appears randomly, so it is fairly hard to reproduce willingly.

Reproduce

docker compose up # compose.yaml in additional info docker compose down --remove-orphans -v docker network rm s_web

Expected behavior

The network should be removed

Additional Info

Running docker rootless on Rocky linux. Same problem seen on multiple servers Using it as CICD runner, the network is created with docker compose up, and should be removed with docker compose down --remove-orphans -v

@akerouanton @robmry PTAL

[sydevinfra]

@fabienpapet FYI

[kodukon]

Still present in Docker. For example, in version 27.5.1 Only restarting docker daemon can fix this problem. But isn't all time. Sometimes you must restart OS. It's totaly worse. Could you force fixing this issue, please?

[akerouanton]

@kodukon There was a tentative fix released in v28.1. Whether it fully fixes the issue, or there are remnants of that error is unclear because we've been unable to reproduce with a simple reproducer (i.e. deterministically). For more details see this comment: https://github.com/moby/moby/issues/42119#issuecomment-2795145433.

Note that v27.5.1 is outdated / unmaintained, and two security fixes have been released recently. So please update your Docker Engine.

As this is an Engine issue, let me close this ticket in favor of https://github.com/moby/moby/issues/42119.
