Apache could not reliably determine the server's fully qualified domain name in docker image

[aasami]

I'm unable to run docker image:

# docker compose up
[+] Running 1/0
 ✔ Container hauk  Created                                                                                                                                                        0.0s

And when I check running services, nothing is listening on port 80.
Even when I try to run it like this:

# docker run -h hauk.mydomain.com bilde2910/hauk

Nothing is listening on port 80. I'm kinda new to docker and don't know how to troubleshoot this.
What can I do about this issue? The readme and docs don't cover this. Thank you

Hi, I get this as well, but it still works fine, I would just ignore it.
Just make sure you set your domain at the bottom of the config.
