Description Adam Kaplan 2019-10-17 15:40:27 UTC
Description of problem:
Image pruning fails if the image registry is removed.
There are cases where the image pruner should be run even if the image registry is removed from the cluster

Version-Release number of selected component (if applicable): 4.1.z

How reproducible: Always

Steps to Reproduce:
1. Update the image registry operator's management state to `Removed`
2. Run the image pruner - `oc adm prune images -prune-registry=false`

Actual results:
Fails to run with error "unable to determine registry: ..."

Expected results:
Image pruner runs, even if registry is not installed on the cluster.

Verified on 4.4.0-0.nightly-2020-01-31-115654.   Image pruner still runs when registry managedState is set to Removed:

# oc adm prune images --prune-registry=false                                                                                                                                                                         
Dry run enabled - no modifications will be made. Add --confirm to remove images                                                                                                                                                               
Only API objects will be removed.  No modifications to the image registry will be made.
