Phase 22

Watchtower

Watchtower can automatically update your Docker containers.

Caution: automatic updates can occasionally break things. Consider using it for low-risk containers first.

Docker Compose

Create: ~/docker/compose/core/watchtower.compose.yml

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

Start:

docker compose -f ~/docker/compose/core/watchtower.compose.yml up -d

Proceed to: Domain + Cloudflare + Caddy
