Pura Vida, todays #OpenSourceDaily project is https://github.com/containrrr/watchtower Watchtower is a container monitoring and auto upgrading service written in go. You can use this to watch your self hosted containers for upstream changes to their base images and automatically update. Or just send notifications about the changes. It can also be configured to connect to private registries so you can automatically update when a new image is pushed in a CI pipeline.
