Can't set GITLAB_MONITOR_CONFIG when using the unprivileged image

[remivoirin]

Hi!

When using the unprivileged image, it's not possible to load custom configurations.

# podman run -p 8080:8080 -e GITLAB_MONITOR_CONFIG=/tmp/config.json timoschwarzer/gitlab-monitor:unprivileged
/wrapper.sh: line 4: can't create /usr/share/nginx/html/config.json: Permission denied

Indeed, root is needed to create a new file in /usr/share/nginx/html, and it looks like wrapper.sh doesn't run with enough rights:

$ ls -ld /usr/share/nginx/html
drwxr-xr-x    1 root     root          4096 Mar 14 12:05 /usr/share/nginx/html

The problem is solved temporarily on my side by predefining the config.
Do you have an opinion on how to solve this inside the project?
