What is this?
Watchtower automates Docker container updates: push a new image to your registry and it pulls it, stops the old container and starts the new version in its place.

Docker is all you need.

Docker is all you need.Can I use it in production?The authors say no: it is intended for homelabs, media centers and local dev environments, with Kubernetes, MicroK8s or k3s suggested instead — and the repo is now archived, so it gets no further maintenance.

A compose file for running Watchtower itself is also in the repo.

In a homelab it keeps working as-is, but expect no fixes going forward.
