I rebooted my centos server and now my OC 10.9.1.2 container is stuck in maintenance mode. I’ve edited config.php and put maintenance false but web still says maintenance mode.
I don’t see anything obvious in logs. My database is up and running and I can get to it via adminer from outside the container.
I don’t know about runuser and why you want to use it. The occ inside the container is already a wrapper script that will handle the user stuff automatically, see base/occ at master · owncloud-docker/base · GitHub
I have posted already a docker exec command that works out of the box. You can also access the container shell as usual using docker exec -it <container_name> bash and run occ maintenance from the shell.
