Where is the config.json file on Windows?

[TheDreadPirate]

Just to verify how this works, I added a custom config.json to my test setup.

My docker compose.

Code:

services:
  jellyfin-testing:
    image: jellyfin/jellyfin:10.10.3
    container_name: jellyfin-testing
    hostname: jellyfin-testing
    user: 1002:1002
    group_add:
      - '993' # Intel render group
    networks:
      blackmoon:
        ipv4_address: 172.16.100.2
    expose:
      - 8096
    volumes:
      - ./jellyfin-stable-data/config:/config
      - ./jellyfin-stable-data/cache:/cache
      - ./jellyfin-stable-data/web/config.json:/jellyfin/jellyfin-web/config.json
      - /media/library:/media/library:ro
      - /media/storage2:/media/storage2
      - /media/ramdisk:/media/ramdisk
    devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
    environment:
      - TZ=America/New_York
    restart: unless-stopped

Ownership of the folders and file.  User ID 1002 from my docker compose corresponds to the "jellyfin" user.

Code:

chris@rat-trap:/docker/containers$ ll -d jellyfin-stable-data/ jellyfin-stable-data/web/
drwxr-x--- 5 jellyfin chris 4096 Jan 21 13:15 jellyfin-stable-data//
drwxr-x--- 2 jellyfin chris 4096 Jan 21 13:18 jellyfin-stable-data/web//
chris@rat-trap:/docker/containers$ ls -l jellyfin-stable-data/web/config.json
-rw-r----- 1 jellyfin chris 1170 Jan 21 13:18 jellyfin-stable-data/web/config.json

The contents of config.json

Code:

chris@rat-trap:/docker/containers$ cat jellyfin-stable-data/web/config.json
{
  "includeCorsCredentials": false,
  "multiserver": false,
  "themes": [
    {
      "name": "Apple TV",
      "id": "appletv",
      "color": "#bcbcbc"
    }, {
      "name": "Blue Radiance",
      "id": "blueradiance",
      "color": "#011432"
    }, {
      "name": "Dark",
      "id": "dark",
      "color": "#202020",
      "default": true
    }, {
      "name": "Light",
      "id": "light",
      "color": "#303030"
    }, {
      "name": "Purple Haze",
      "id": "purplehaze",
      "color": "#000420"
    }, {
      "name": "WMC",
      "id": "wmc",
      "color": "#0c2450"
    }
  ],
  "menuLinks": [
      {
          "name": "Main Jellyfin",
          "url": "https://jellyfin.domain.tld"
      }
  ],
  "servers": [],
  "plugins": [
    "playAccessValidation/plugin",
    "experimentalWarnings/plugin",
    "htmlAudioPlayer/plugin",
    "htmlVideoPlayer/plugin",
    "photoPlayer/plugin",
    "comicsPlayer/plugin",
    "bookPlayer/plugin",
    "youtubePlayer/plugin",
    "backdropScreensaver/plugin",
    "pdfPlayer/plugin",
    "logoScreensaver/plugin",
    "sessionPlayer/plugin",
    "chromecastPlayer/plugin",
    "syncPlay/plugin"
  ]
}

And it appeared as expected.

   

So let's check the ownership of your config.json, since everything else you shared appears to be in order.

Code:

ls -ld /home/username /home/username/Dockers /home/username/Dockers/Jellyfin /home/username/Dockers/Jellyfin/Config
ls -l /home/username/Dockers/Jellyfin/Config/*
