Homelab - Tool for Automatically Updating Docker Containers: Watchtower

Watchtower is a tool for automating the updates of all or selected Docker containers.

Deployment (Docker Compose)

To begin, create a compose.yaml file and paste the following content:

version: "3"
services:
  watchtower:
    container_name: ${STACK_NAME}_app
    image: containrrr/watchtower:${APP_VERSION}
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    restart: always

(Optional) It is recommended to create a .env file in the same directory as compose.yaml and customize your environment variables. If you prefer not to use environment variables, you can directly customize your parameters within compose.yaml (for example, replacing ${STACK_NAME} with watchtower).

STACK_NAME=watchtower

# watchtower
APP_VERSION=latest

Finally, execute the docker compose up -d command in the same directory as compose.yaml to start the orchestrated containers.
