Description Adam Kaplan 2020-02-21 20:12:39 UTC

Description of problem:

If the automatic image pruner is enabled and the image registry itself is `Removed`, the image pruning jobs can fail.


Version-Release number of selected component (if applicable): 4.4.0


How reproducible: Always


Steps to Reproduce:
1. Create an image pruner CRD
2. Mark the internal registry as `Removed`
3. Run the image pruner

Actual results:

Image pruner jobs fail trying to prune images from the non-existent registry.


Expected results:

Image pruner jobs only prune image metadata in etcd.
