How to automatically remove unused images once the container is updated by watchtower?

Hey Guys,

Is there something we can install to automatically remove unused images once the container has been updated by watchtower?

Thanks for your inputs!

cheers

Thanks All!

I used the below stack :

version: "2"

services:

watchtower:

container_name: watchtower

image: containrrr/watchtower

volumes:

- /var/run/docker.sock:/var/run/docker.sock

environment:

- WATCHTOWER_CLEANUP=true

- WATCHTOWER_POLL_INTERVAL=86400 #check for updates once per day

restart: unless-stopped

Awesome!
