[BUG] - Containers not able to run in parallel about arr-scripts HOT 5 CLOSED

You can run multiple containers, what your experiencing is a user misconfiguration issue on your part… without knowing the specifics of how you configured it, can’t help you much. But I can tell you this is not a bug because I already do this and it’s just a problem on your end…

If I had to guess, you modified lidarr’s internal port, when you should never be changing the port because changing the lidarr internal software port is not needed when running multiple containers…

But I’m just making an assumption/educated guess…

It's not an user error, I kinda hastily wrote this and forgot to mention how I setup them. Thats my bad.

I have a VPN container which I use for all of my arrs, meaning they all share the same docker network, hence I cannot use the same port for the second Lidarr container and I was forced to change it. They are individual containers but connect to the VPNs docker network.

The method you are using to change the ports is incorrect. You don’t change the internal port, only change the exposed port.

As I said, I’m already running multiple containers, so it’s a non issue.

from arr-scripts.

[Fatal] ConsoleApp: Failed to bind to address http://[::]:8686: address already in use. This can happen if another instance of Lidarr is already running another application is using the same port (default: 8686)

I'm not sure how yours is setup but I simply cannot get rid of this error unless I change the internal port. However I have no trouble maintaining my own fork of this with the fix for my issue, just thought to post here if it was issue affecting other people as well.

Agreed it’s a container issue. If you’re using docker compose, here’s how you would bind the container internal port 8686 to 3535 as I did in a second lidarr container:
