Get your FREE "elfhosted" Jellyfin instance for demo / trial 🥳

Want to see a live demo, or "kick the tyres" 🚙 before you commit to self-hosting Jellyfin?

Try out an "ElfHosted" 🧝 instance of Jellyfin for FREE!

Jellyfin is best described as "like Emby but really FOSS".

Jellyfin Screenshot

If it looks very similar as Emby, is because it started as a fork of it, but it has evolved since them. For a complete explanation of the why, look here.

Jellyfin Requirements


Already deployed:



Setup data locations

We'll need a location to store Jellyfin's library data, config files, logs and temporary transcoding space, so create /var/data/jellyfin, and make sure it's owned by the user and group who also own your media data.

mkdir /var/data/jellyfin

Also if we want to avoid the cache to be part of the backup, we should create a location to map it on the runtime folder. It also has to be owned by the user and group who also own your media data.

mkdir /var/data/runtime/jellyfin

Prepare Jellyfin environment

Create jellyfin.env, and populate with PUID/GUID for the user who owns the /var/data/jellyfin directory (above) and your actual media content (in this example, the media content is at /srv/data)


Jellyfin Docker Swarm config

Create a docker swarm config file in docker-compose syntax (v3), something like the example below:

Fast-track with premix! 🚀

I automatically and instantly share (with my sponsors) a private "premix" git repository, which includes necessary docker-compose and env files for all published recipes. This means that sponsors can launch any recipe with just a git pull and a docker stack deploy 👍.

🚀 Update: Premix now includes an ansible playbook, so that sponsors can deploy an entire stack + recipes, with a single ansible command! (more here)

version: "3.0"

    image: jellyfin/jellyfin
    env_file: /var/data/config/jellyfin/jellyfin.env
      - /etc/localtime:/etc/localtime:ro
      - /var/data/jellyfin:/config
      - /var/data/runtime/jellyfin:/cache
      - /srv/data/:/data
        - "traefik.enable=true"
        - ""
        - "traefik.http.routers.jellyfin.rule=Host(``)"
        - ""

        - traefik_public
      - 8096:8096

    external: true


Setup unique static subnets for every stack you deploy. This avoids IP/gateway conflicts which can otherwise occur when you're creating/removing stacks a lot. See my list here.


Launch Jellyfin stack

Launch the stack by running docker stack deploy jellyfin -c <path -to-docker-compose.yml>

Log into your new instance at https://YOUR-FQDN, and complete the wizard-based setup to complete deploying your Jellyfin.

Chef's notes 📓

  1. I didn't use an oauth2_proxy for this stack, because it would interfere with mobile client support. 

  2. Got an NVIDIA GPU? See this blog post re how to use your GPU to transcode your media! 

  3. We don't bother exposing the HTTPS port for Jellyfin, since Traefik is doing the SSL termination for us already.
