Nginx Proxy Manager
Docker container for managing Nginx proxy hosts with a simple, powerful interface
Prime example: Nginx Proxy Manager is often recommended in the sub. The latest minor release came with breaking changes (so already ignoring semver). I bet you many people were running on latest and then had broken stuff: https://github.com/NginxProxyManager/nginx-proxy-manager/releases/tag/v2.10.0

docker-lock
Discontinued Automatically manage image digests in Dockerfiles, docker-compose files, and Kubernetes manifests by tracking them in a separate Lockfile
I do both! I tag my services with :latest, then use docker-lock. It scans your docker and docker-compose, generates a lock file and adds the current sha to git. That lets me freely update because I can always go get the previous version from git, rollback, and pin the version for that specific container if there is a problem. It really is the best of both worlds.

You commit your docker-compose.yml file(s) to a GitHub repo (don't commit secrets!!), then add the Renovate App to your repo, merge the onboarding PR, then you'll get PRs when an image is updated.
