Updating Docker Images

Watchtower

To easily manage docker image updates in a #homelab setting, look into using Watchtower by "containerrr"

Basic startup command

docker run -d \
  --name watchtower \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower

By default, Watchtower will update all running containers on the system. To have it monitor specific images, specify their name on the command line as an argument, no flag needed.
