Description of problem: When running must-gather using CNV image 4.10.0-104, the action fails with ImagePullBackOff Version-Release number of selected component (if applicable): Client Version (oc): 4.10.0-202201281850.p0.g7c299f1.assembly.stream-7c299f1 Server Version: 4.10.0-fc.4 Kubernetes Version: v1.23.0+d30ebbc CNV: v4.10.0-629 CNV must-gather: v4.10.0-104 How reproducible: Always Steps to Reproduce: 1. Run CNV must gather $ oc adm must-gather --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.10.0-104 --dest-dir=mg-out/ Actual results: $ oc adm must-gather --image=registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.10.0-104 --dest-dir=mg-out/ [must-gather ] OUT Using must-gather plug-in image: registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.10.0-104 When opening a support case, bugzilla, or issue please include the following summary data along with any other requested information. ClusterID: 78adf009-128a-478e-a2d1-5c49ad4ac1ab ClusterVersion: Stable at "4.10.0-fc.4" ClusterOperators: All healthy and stable [must-gather ] OUT namespace/openshift-must-gather-q82nz created [must-gather ] OUT clusterrolebinding.rbac.authorization.k8s.io/must-gather-l2cdq created [must-gather ] OUT pod for plug-in image registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.10.0-104 created [must-gather-zrv65] OUT gather did not start: unable to pull image: ImagePullBackOff: Back-off pulling image "registry.redhat.io/container-native-virtualization/cnv-must-gather-rhel8:v4.10.0-104" [must-gather ] OUT clusterrolebinding.rbac.authorization.k8s.io/must-gather-l2cdq deleted [must-gather ] OUT namespace/openshift-must-gather-q82nz deleted Expected results: Success in pulling CNV image and gathering data. Additional info: When running with the default image (and not the CNV image), the command succeeds. $ oc adm must-gather --dest_dir=mg-out
Resolved by using the sha1 for the image URL, instead of the z-stream sub-version (104).
