[BUG] FPM initialization failed, fastcgi address in use

[tobinstultiens]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Currently when running this docker file I will receive the following error in the webpage: File not found.

While when I look at the logs I see these errors.

FPM initialization failed
unable to bind listening socket for address '127.0.0.1:9000': Address in use (98)

This is related to a nginx configuration not being set correctly / not being able to change it with the current setup.
If I go to config/grocy/nginx/site-confs/default.conf
I see the following port set which is causing the issues.

Expected Behavior

I would expect grocy to launch when going to the webpage.

Steps To Reproduce

1. Setup the docker file.
2. Have a program running that is using the 9000 port. (Honestly nothing is running at that port for me but I'm still receiving the error.)
3. ???
4. Profit

Environment

- OS: Arch 6.4.12-arch
- How docker service was installed: Pacman

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

network_mode: container:vpn this is the culprit. We dont support routing containers trough other containers.

network_mode: container:vpn

You're telling grocy to use another container's network stack. Something else is bound to port 9000 in that network, perhaps yet another container using that one's network stack.

[tobinstultiens]

Ah yes that would resolve it. Maybe a follow up question are there plans or will it ever be possible to manage these values?

[Roxedus]

No, it will complicate the codebase a lot for a very niche type of setup.

[aptalca]

You can route via routing tables

Oh, interesting didn't know that was possible with wireguard thanks.

Thanks for the help.
