# watchtower Setup 

![](0.png)

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
    	
    

![]()
    
    
    [ nowhere.moe ] [ /dev/pts/4 ] [/srv/watchtower]
    → vim docker-compose.yml
    
    [ nowhere.moe ] [ /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
    
    [ nowhere.moe ] [ /dev/pts/4 ] [/srv/watchtower]
    → docker-compose up
