Plex is a client-server media player system and software suite comprising two main components (a media server and client applications)

Plex Requirements


Already deployed:



Setup data locations

We'll need a directories to bind-mount into our container for Plex to store its library, so create /var/data/plex:

mkdir /var/data/plex

Prepare Plex environment

Create plex.env, and populate with the following variables. Set PUID and GUID to the UID and GID of the user who owns your media files, on the local filesystem


Plex 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)

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 Plex stack

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

Log into your new instance at https://YOUR-FQDN (You'll need to setup a login for remote access / discovery to work from certain clients)

Chef's notes 📓

  1. Plex uses port 32400 for remote access, using your user/password to authenticate you. The inclusion of the traefik proxy in this recipe is simply to allow you to use the web client (as opposed to a client app) by connecting directly to your instance, as opposed to browsing your media via 

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