Docker Engine does not start on Ubuntu 22.04 due to iptables issues

Open spirillen opened this issue 1 year ago • 5 comments

Description

Some time ago I updated, I did a usual system update and after that, docker refuses to start.

For some reason, It can no longer recognize an existing bridge

Reproduce

No longer recalls the process for when it started, beside the update process.

See log output of dockerd -D below.

Expected behavior

Docker can recognize it's own network bridge

PS: Why do you still uses iptables commands? it have been deprecated for years.

Description Some time ago I updated, I did a usual system update and after that, docker refuses to start.

For some reason, It can no longer recognize an existing bridge

Reproduce No longer recalls the process for when it started, beside the update process.

See log output of dockerd -D below.

Expected behavior Docker can recognize it's own network bridge

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I have removed all interfaces and firewalld docker zone, but no luck. How can I further debug or contribute to resolving this have same bridge name issue?

I erased the /var/lib/docker/networks directory which resolved the issue for me. Not sure what caused it though.

cf-sewe avatar Aug 28 '24 11:08 cf-sewe

Thanks, how did you come up with that solution?

Some googling , research and then found a hint here: https://bbs.archlinux.org/viewtopic.php?id=214311
