[FEATURE] Question - is it possible to use version-checker to alert for missing images #395
Description
Is your feature request related to a problem? Please describe.
We recently had a problem where coreos/zetcd images were removed from upstream registry, we restarted the StatefulSet and unable to pull images the application had downtime.
Bitnami are going to remove a number of tags on 28th Aug (renamed to bitnamilegacy).
With this in mind we are thinking about being able to alert when an image+tag specified by a Pod no longer exists in the registry.
Describe the solution you'd like
One of the metrics version_checker_image_failures_total makes the most sense to me - being able to report that upstream image / tag does not exist.
Describe alternatives you've considered
So far we've only thought about writing our own app that pulls all images and then does an equivalent of docker manifest inspect.
