Updating Watchtower

If watchtower is monitoring the same Docker daemon under which the watchtower container itself is running (i.e. if you volume-mounted /var/run/docker.sock into the watchtower container) then it has the ability to update itself.
If a new version of the containrrr/watchtower image is pushed to the Docker Hub, your watchtower will pull down the new image and restart itself automatically.
