A simple way to run a plex media server in Docker on the Raspberry Pi.

NOTE: The Pi 1 is NOT supported.

Install docker on your raspberry pi. There are numerous ways to do this but the easiest is to run:

curl -sSL https://get.docker.com | sh

Source: https://www.raspberrypi.org/blog/docker-comes-to-raspberry-pi

Next, you'll need to create three local folders for the plex config, data and transcode volumes (I have all of these on an external HDD because they get very large). For example:

mkdir -p ~/media/plex/{config,data,transcode}

Using the above folders, run the following to start plex:

docker run \
  -d \
  --name plex \
  --net host \
  --restart always \
  --volume $(echo $HOME)/media/plex/config:/config \
  --volume $(echo $HOME)/media/plex/data:/data \
  --volume $(echo $HOME)/media/plex/transcode:/transcode \
  greensheep/plex-server-docker-rpi:latest

After around 30 seconds, the Plex web admin should be available at http://{ip address of Pi}:32400/web.

If you have permission issues using NFS shares as the mounted volumes, set the SET_PLEX_UID and SET_PLEX_GID environment variables to the user/group id of the owner of those directories.

# show user/group owner of a directory
ls -n ~/media/plex/config

# outputs something like this:
# drwxr-xr-x 20 1001  1001  4096 Apr  9 19:00 config
#               ^ uid ^ gid

docker run \
  -d \
  --name plex \
  --net host \
  --restart always \
  -e SET_PLEX_UID=1001 \
  -e SET_PLEX_GID=1001 \
  --volume $(echo $HOME)/media/plex/config:/config \
  --volume $(echo $HOME)/media/plex/data:/data \
  --volume $(echo $HOME)/media/plex/transcode:/transcode \
  greensheep/plex-server-docker-rpi:latest

Plex cannot be updated via the web ui. Run the following to download and run a new version:

docker pull greensheep/plex-server-docker-rpi:latest
docker stop plex
docker rm -f plex
# `docker run ...` command from above!

The Pi isn't powerful enough for transcoding but if you have media that will direct play on your client it works great! I've tested this on the Pi 2 (Hypriot) and 3 (Arch) and 4 (ubuntu).

Be sure to set the "Transcoder temporary directory" setting to /transcode in the Plex -> Transcoder settings UI.

To build the images yourself clone this repository and run the following:

sudo docker buildx build -t plex-dev:latest --platform linux/arm,linux/arm64 .
