How to deploy container Gitlab on a mounted point? - docker

Question

I'm trying to mount one container Gitlab on my CIFS mounted point, but that returns errors.
I have my Nas CIFS mounted point at /mnt/serveurwiki/ and i have 2 folders in "gitlab" and "wiki".
As you can see, I have all rights on the folder.
And this is my docker-compose.yml:
version: '3.6'
services:
gitlab:
image: gitlab/gitlab-ce:latest
user: root
ports:
- '42007:80'
- '42008:443'
- '42009:22'
volumes:
- /mnt/serveurwiki/gitlab/config:/etc/gitlab
- /mnt/serveurwiki/gitlab/logs:/var/log/gitlab
- /mnt/serveurwiki/gitlab/data:/var/opt/gitlab
networks:

For precision, I tested the compose in other positions and all work, but when I try to deploy my container in my point mount (/mnt/serveurwiki), I have that error in the logs of the container.

Anyone have an idea what I can do for that and why I have that error?

Answer 1

For testing, you could:
build your own image based on gitlab/gitlab-ce:latest
change the ENTRYPOINT to call your own script before calling the one from GitLab
check/change the permissions of /var/opt/gitlab in your custom ENTRYPOINT script.
That way, you have a better control of the environment used by the GitLab image.
