Where does the application look for the discord socket on linux?

[braccae]

EDIT: markdown :/

I'm probably missing something obvious here, but I've containerized the application but despite binding the discord socket into it and assuring the permissions are correct, it seems to not connect. I have tested to make sure that it works without docker. For now, I've created a systemd unit file to run it in the background but I'd like to put it into the podman pod I have all of my other rpc plugins in.

The end goal is to run in a pod with a containerized discord using the linuxserver.io image, mounting the discord socket between each container.

My dockerfile:

notes: Ideally I'd like to use the scratch image as the base and only include the binary, but that doesn't work out very well with rust projects. After I get the debian image working, I plan to look into rebuilding with musl and using alpine.

FROM debian:bookworm-slim
WORKDIR /
ADD --chmod=333 https://github.com/Radiicall/jellyfin-rpc/releases/download/1.3.0/jellyfin-rpc-x86_64-linux /jellyfin-rpc
VOLUME ["/config"]
CMD ["/jellyfin-rpc", "--config", "/config/main.json"]

My compose file:

notes: I've tried running without the user, and with read only on the socket. I've also tried bind mounting the entire /run/user/1000 directory to both the /tmp and /run/user/1000 directories inside the container to no avail.

services:
  jellyfin-rpc:
    build: .
    user: 1000:1000
    #restart: unless-stopped
    volumes:
      - ./test/config:/config
      - /run/user/1000/discord-ipc-0:/tmp/discord-ipc-0:rw```
