Updates#

Docker stack (Sonarr, Radarr, Prowlarr, SABnzbd, Overseerr)#

All automation services use lscr.io/linuxserver/* images tagged as latest. To update them:

cd /path/to/your/docker-compose
docker compose pull
docker compose up -d

This pulls the latest image for each service and recreates any containers whose image changed. Containers that are already on the latest image are left untouched.

Config data lives in /srv/media-stack/config/ and persists across updates because it is mounted as a volume.

Automating updates with Watchtower#

If you want automatic updates without manual intervention, you can run Watchtower↗ as an additional container. It monitors your running containers and pulls new images on a schedule.

watchtower:
  image: containrrr/watchtower
  container_name: watchtower
  volumes:
    - /var/run/docker.sock:/var/run/docker.sock
  environment:
    - WATCHTOWER_SCHEDULE=0 0 4 * * *
    - WATCHTOWER_CLEANUP=true
  restart: unless-stopped

This runs the update check daily at 04:00 and removes old images after updating.

Plex (LXC)#

Plex Media Server on Debian is updated through apt:

apt update
apt install --only-upgrade plexmediaserver

Plex restarts automatically after the upgrade. Active streams may be interrupted briefly.

To check the currently installed version:

dpkg -l plexmediaserver

Proxmox host#

Keep the Proxmox host itself updated separately:

apt update && apt upgrade -y

Check the Proxmox changelog↗ before major version upgrades.
