Docker Hub Update Notifications

Question

Are there any good methods/tools to get notifications on updates to containers on Docker Hub? Just to clarify, I don't want to automatically update, just somehow be notified of updates.

I'm currently running a Kubernetes cluster so if I could just specify a list of containers (as opposed to it using the ones on my system) that would be great.

Answer 1

Have you tried docker-notify? It runs on Node (perhaps imperfect).. but within it's own container. You'll need a mailserver or a webhook for it to trigger against.

I'm surprised this isn't supported by docker.exe or Docker-hub.. base image changes (eg Alpine) cause a lot of churn with both hub-dependent (Nginx, Postgres) and local dependent containers possibly needing rebuild.
