Description Wenjing Zheng 2020-02-26 07:55:04 UTC 
This bug was initially created as a copy of Bug #1806019

I am copying this bug because: 



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.

This is for 4.5: https://bugzilla.redhat.com/show_bug.cgi?id=1806019
Comment 3 Wenjing Zheng 2020-03-26 05:59:32 UTC 
For the 4.5 fix, there is one warning for image pruner when image registry is removed(https://bugzilla.redhat.com/show_bug.cgi?id=1806019#c3):
$ oc logs pods/image-pruner-1583834340-ln8wn
Only API objects will be removed.  No modifications to the image registry will be made.

Although for 4.4 image pruner no fail after image registry is removed.
Comment 4 Corey Daley 2020-03-26 14:22:10 UTC 
If the image registry is marked as "Removed", the --prune-registry flag is removed, so this is the correct behavior.
