DockerClient->startContainer return: Server error - what does it mean?


Recommended Posts



I use the https://github.com/limetech/webgui/blob/master/plugins/dynamix.docker.manager/include/DockerClient.php to stop/start some containers. It returns `$code` which is normally "1". But sometimes I get "Server error" back. But I dont see any messages inside the system log. What could cause "Server error" and how could I debug it?


Thanks in advance!

docker run would probably tell you why

Are those actions not logged via docker.log?


I remember, that I got something out of docker, using docker run:

Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error running hook #0: error running hook: exit status 1, stdout: , stderr: time="2022-11-09T17:46:39+01:00" level=fatal msg="failed to set IPv6 gateway while updating gateway: file exists": unknown
Error: failed to start containers: mysql


I dont know if this is a docker issue only here.


However, does the API (used by DockerClient) return more info here, which could be added to the return variable?
