Secret and Config Permission conflict

[jeromeatneotek]

A conflict exists between the permissions required for password file secrets and config.php being updated.

Becuase the container is running as www-data it cannot use the password files which are either root or another user and also be able to save the config file.

I found that Docker recommend that all images actually start with root permissions and adjust them after secrets are loaded within the entrypoint.sh

I built a custom image with this approach and everything worked fine.
