Zammad-NGINX can not write config file due to read-only #381

Closed strifel closed 10 months ago

strifel commented 10 months ago

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

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 https://github.com/zammad/zammad-docker-compose/commit/ffa1268a2aab5b459b255c63e004b011117b3c0f 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.
