Easy as it sounds, just see the linuxserver docs: https://docs.linuxserver.io/images/docker-plex/
Use the image ghcr.io/skjnldsv/docker-plex:nightly. Also make sure you pass your amd device like so:
ghcr.io/skjnldsv/docker-plex:nightly
devices: - /dev/dri:/dev/dri
version: "3.7" services: plex: image: ghcr.io/skjnldsv/docker-plex:nightly restart: unless-stopped container_name: plex ports: # Default access - target: 32400 published: 32400 mode: host # https://support.plex.tv/articles/201543147-what-network-ports-do-i-need-to-allow-through-my-firewall/ # Plex Home Theater control - 8324:8324/tcp # GDM discovery - 32410:32410/udp - 32412:32412/udp - 32413:32413/udp - 32414:32414/udp environment: - TZ=Europe/Berlin - VERSION=docker devices: - /dev/dri:/dev/dri volumes: - /mnt/config:/config - /mnt/storage:/storage
