Comment 7 Dongbo Yan 2018-05-28 11:08:20 UTC 
Verified
openshift v3.7.51
kubernetes v1.7.6+a08f5eeb62
etcd 3.2.8

Reproduce steps:
1. Edit dc with invalid image reference in 'image' field like below:
        image: docker-registry.default.svc:5000/dyan/cakephp-mysql-example@sha256:latest

2. Prune images
 $ oc adm prune images --keep-tag-revisions=0 --keep-younger-than=0 --token=jf9HRi58RqN0GqBerRyn9UHXHxAvQImhlr6tJ5RhDYE --confirm --loglevel=4

Failed to build graph!

The following objects have invalid references:

  Pod[dyan/cakephp-mysql-example-6-hook-pre]: invalid docker image reference "docker-registry.default.svc:5000/dyan/cakephp-mysql-example@sha256:latest": invalid reference format
  ReplicationController[dyan/cakephp-mysql-example-6]: invalid docker image reference "docker-registry.default.svc:5000/dyan/cakephp-mysql-example@sha256:latest": invalid reference format
  DeploymentConfig[dyan/cakephp-mysql-example]: invalid docker image reference "docker-registry.default.svc:5000/dyan/cakephp-mysql-example@sha256:latest": invalid reference format

Either fix the references or delete the objects to make the pruner proceed.

3. Prune images with option '--ignore-invalid-refs'
could prune images without errors
