> How to update the Docker-based automation stack and the Plex LXC to their latest versions.

# Updates

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

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

```bash
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](https://containrrr.dev/watchtower/) as an additional container. It monitors your running containers and pulls new images on a schedule.

```yaml
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`:

```bash
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:

```bash
dpkg -l plexmediaserver
```

## Proxmox host

Keep the Proxmox host itself updated separately:

```bash
apt update && apt upgrade -y
```

Check the [Proxmox changelog](https://www.proxmox.com/en/downloads/proxmox-virtual-environment/changelog) before major version upgrades.
