Zammad-NGINX can not write config file due to read-only

[strifel]

Infos

• Docker version: 24.0.6
• Docker-compose version: 2.11.1
• Operating system (Docker host): Ubuntu 22.04

Expected behavior

• The zammad-nginx container writes a working nginx config

Actual behavior

• /docker-entrypoint.sh: line 119: /etc/nginx/sites-enabled/default: Read-only file system

Steps to reproduce the behavior

• Use docker-compose file from this repository

Line 96 in 07936ea

- zammad-config-nginx:/etc/nginx/sites-enabled:ro

sets the /etc/nginx/sites-enabled path as read-only.

Writes the nginx config in

Further questions

Is there any reason why the init container has access to the nginx config as well? This threw me off quite a bit during the search for the problem.

Is there any reason why the nginx container has it mounted?
This seems to have been added in ffa1268 without further explanation

Thanks for your report @strifel. It does not fail in the same way for me, but I agree that something is wrong with the current volume handling.
