[root@xxx dc-gitlab]# docker start cce932ba5dc2
Error response from daemon: network ase6cd78ccf7f24c49871653f2dd not found
Error: failed to start containers: css932ba5dd3

The above are error messages. The previous bridging is configured.

Solution:

docker-compose up -d --force-recreate

It can be solved.

Scene:

During the production launch, the port of the gitlab started by Docker cannot be accessed suddenly. It is OK to check the corresponding server listening port. It can be pinged, but the telnet port is not. In an hurry to go online, I had to restart the server and Docker, and then the above problem occurred.
