OpenShift v4.x - ImagePrunerDegraded: Job has reached the specified backoff limit

본 이슈는 내부 레지스트리인 image-registry의 Operator 상태가 Degraded로 발생하는 이슈이다.

해당 버그 리포트를 살펴보면 OCP v4.4 버전에서도 발생했던 사항으로,
이슈가 발생하는 시점은 image-registry operator의 managementState를 Removed 상태에서 pruner job이 생성이 될때까지 기다리면 발생한다. (현재 OCP v4.6은 managementState는 Removed가 기본)

1. 이슈

[root@bastion ~]# oc describe clusteroperators image-registry | grep 'ImagePrunerDegraded'

"""
This module implements an Ansible plugin that is triggered at the start of a playbook.

The plugin dynamically generates a tag for each role. Each tag has the same name as its role.
The advantage of this is that it saves you some boilerplate, because you don't have to wrap
all tasks of a role in an additional block and assign a tag to that.
Additionally, it works automatically when you add new roles to your playbook.

Usage is exactly the same as without this plugin:
