How to receive notifications about image/base image updates?

General

Hi all!

I run a few Docker containers on a single server with docker-compose. From administrating regular Linux servers, I am used to have a cron job that notifies me when new/corrected versions of the distribution packages are available for install. I am now wondering how that is done in the Docker world.
Is there an equivalent to cron-apt that would send me an email when a base image for my own containers or an image that I use unmodified from Docker Hub has a new release so that I can update my containers?

Best regards,
Reiner

Yes, that sounds very promising. Thanks for pointing it out. I will try it.

If you prefer notifications-as-a-service, I helped make image-watch.com, which can watch base images on a given hub and notify you of changes.
