[BUG] NGINX_PORT Variable doesn't work

[swooshant]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When setting the NGINX_PORT environment variable, it does not change. It still uses port 80 and the variable doesn't do anything.

Expected Behavior

When changing the NGINX_PORT environment variable, I expect the internal server to begin listening on the specified port. However, it only continues to listen to port 80 as seen in the logs and in ability for me to connect to the new port.

Steps To Reproduce

Using docker compose provided below, pass the NGINX_PORT variable as an environment variable. Check the logs and you'll see it defaults to listening to 127.0.0.1:80 no matter what you change it to.

Environment

- OS: Ubuntu 24.04
- How docker service was installed:
distro's packagemanager

CPU architecture

The variable is only used on first run, the file is then written to /config for persistent storage

Ah that makes sense, I will close out this issue then. Didn't realize it was doing that.

I'm not really sure why this is written to persistent storage. I was banging my head against a wall trying to figure this out. It should be at least documented that if you need to change the port you need to blow away the container or change the /config files.
