Steps to reproduce
- New install on a remote Debian 10 host
- Using docker-compose from the official doc or using a standalone docker install
- Bring up the stack first time and everything works fine, reboot and owncloud logs complain of “The username is already being used” and refuses to start (Duplicate of this issue 104 in GitHub for own cloud-docker).
- I can get it to start by logging into the MariaDB container and dropping the owncloud database
- I was suspecting that I was not linking the volumes from your container to the host properly. I tried with volume as well as the bind mount with the same result.
Observations
- The official docs talk about mapping /mnt/data from the container to the local host. When doing that the following 4 folder are mapped to the local host
drwxr-xr-x 2 www-data root 4096 Feb 19 12:50 apps
drwxr-xr-x 2 www-data root 4096 Feb 19 12:50 config
drwxrwx--- 4 www-data root 4096 Feb 19 13:07 files
drwxr-xr-x 2 www-data root 4096 Feb 19 12:52 sessions
The config folder has the following 2 files
-rw-r--r-- 1 www-data root 1038 Feb 19 12:50 objectstore.config.php
-rw-r--r-- 1 www-data root 18749 Feb 19 12:51 overwrite.config.php
What I can’t understand is why is config.php not being mapped to the local host ? I think it is because of this that every time the container restarts it looses its state and wants to create the DB again and therefore throws up the error. The user data on the other hand is persisting across reboots and behaving normally.
I tried doing a standalone install (without docker-compose) with the same result. The config.php is only on the container and not mapped to the local host. Every reboot I have to edit it to add the trusted_domains.
Anyone has any clues ?
Note:
Below docker-compose shows bind mounts, I am getting the same result for volumes also.
