Jellyfin in docker

guide-by-example

Purpose & Overview

Stream movies/tv-shows/music to a browser, or a large selection of devices and services.

• Official site
• Github
• DockerHub

Jellyfin if a free media system, an alternative to proprietary Plex.
The core server side is written in C#, web client in Javascript, and a number of other clients written in various languages and frameworks.

Starting point for me was this viggy96 repo

Files and directory structure

            └── docker-compose.yml

• /mnt/bigdisk/... - a mounted media storage share
• jellyfin_cache/ - cache
• jellyfin_config/ - configuration
• transcodes/ - transcoded video storage
• .env - a file containing environment variables for docker compose
• docker-compose.yml - a docker compose file, telling docker how to run the containers

You only need to provide the two files.
The directories are created by docker compose on the first run.

docker-compose

The media are mounted in read only mode.

docker-compose.yml

services:

  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin
    hostname: jellyfin
    restart: unless-stopped
    env_file: .env
    devices:
      - /dev/dri
    volumes:
      - ./transcodes/:/transcodes
      - ./jellyfin_config:/config
      - ./jellyfin_cache:/cache
      - /mnt/bigdisk/serialy:/media/video:ro
      - /mnt/bigdisk/mp3/moje:/media/music:ro
    ports:
      - "8096:8096"
      - "1900:1900/udp"

networks:
  default:
    name: $DOCKER_MY_NETWORK
    external: true

.env

# GENERAL
DOCKER_MY_NETWORK=caddy_net
TZ=Europe/Bratislava

All containers must be on the same network.
Which is named in the .env file.
If one does not exist yet: docker network create caddy_net

Reverse proxy

Caddy is used, details here.

Caddyfile

jellyfin.{$MY_DOMAIN} {
    reverse_proxy jellyfin:8096
}

First run

Specifics of my setup

• no real long term use

• findroid app does not jump subtitles like official one

• amd cpu and no gpu, so no experience with hw transcoding

• media files are stored and shared on trunas scale VM and mounted directly on the docker host using systemd mounts, instead of fstab or autofs.

Troubleshooting

We're unable to connect to the selected server right now. Please ensure it is running and try again.

If you encounter this, try opening the url in browsers private window.
If it works then clear the cookies in your browser.

No playback at all but GUI works fine

Might be no access to network share, for example if dockerhost boots up faster than NAS.

Update

Manual image update:

• docker-compose pull
  
• docker-compose up -d
  
• docker image prune
