watchtower Setup

In this tutorial we'll setup a watchtower container, used to upgrade all all docker images automatically

Initial Setup

First install the required packages:

apt install docker.io docker-compose
	

[ Datura-Network ] [ /dev/pts/4 ] [/srv/watchtower]
→ vim docker-compose.yml

[ Datura-Network ] [ /dev/pts/4 ] [/srv/watchtower]
→ cat docker-compose.yml
version: "3"
services:
  watchtower:
    image: containrrr/watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

[ Datura-Network ] [ /dev/pts/4 ] [/srv/watchtower]
→ docker-compose up
