Run Certbox with the Zammad Docker Version

I’d like to use Docker to run Zammad, and installed it fine (using Zammad docs to guide me).
Whoever I tried to run certbot and it fails.

The first time I installed Zammad I did not use the Docker version, and using the certbot was an easy, few minutes ordeal. Same OS (CntOS) and same instructions on how to use the certbot, and it fails.
So I guess this is somehow related to Zammad docker version, there’s something I need to do differently than if I was installing Zammad without docker.

Can someone shed some light?

sounds like certbot can’t find your nginx-Installation inside the docker.
Maybe the following forum thread helps you:

If everything else doesn’t work, you could also use standalone and then regulary stop nginx during certbot-runtime via crontab if the extensions don’t want to work cleanly for you.
