[BUG] Docker image does not talk about port 8310

[Jeremy-Lemoine]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

1. When we use port 8310 by exposing the port in docker container, the port exists and is a web UI.

2. This port (8310) is not the one used in the image documentation (7878) as you can see here
   

3. The 8310 port isn't even in the list of ports when we call "docker inspect radarr", unless we expose it manually. If we do not expose any port, we have this:
   

4. In "docker logs radarr", we can see that the port 8310 is the one listened to.
   

Expected Behavior

The port 8310 should be in the list of image ports, globally defined, such as 7878, even if we do not expose it in docker-compose.yml.

Steps To Reproduce

Run a container with this image, with no exposed port, and notice "docker inspect radarr" displays only 7878 port.

Run the same container but with 8310 port exposed, and notice "docker inspect radarr" displays 7878 AND 8310 ports and that a web UI is behind the 8310 port.

The default port is 7878, you have overridden it by telling Radarr to run on 8310, we do not enforce the default port.
This default is also present in the test we do on each build, https://ci-tests.linuxserver.io/linuxserver/radarr/latest/index.html

[Jeremy-Lemoine]

I did not override the default port. I noticed the default port 7878 was not working, there is no web UI at localhost:7878 when we try it. But when I expose (without editing any environment variable or anything) 8310, the port is working.

[j0nnymoe]

Something you've done has caused it to run on that port. You can see from our CI tests that it clearly runs on 7878.

[Roxedus]

remove port 8310 from /config/config.xml, and restart. it will then start on the default port again.

Oooooh thank you, I guess we might have copied the config directory from a former radarr, which kept the 8310 port… Thank you very much! Sorry for the false alarm
