+++ This bug was initially created as a clone of Bug #1777031 +++ +++ This bug was initially created as a clone of Bug #1777030 +++ oc debug node uses registry.redhat.io/rhel7/support-tools, but this container image is only available on AMD64. It should be updated to use registry.redhat.io/rhel8/support-tools, which is a multi-arch container image.
I was able to verify this patch with a locally built oc client.
Apparently we can't support RHEL8 container images on RHEL7 nodes, so the current solution isn't going to work on RHEL7 workers. We are going to try to get the RHEL7 support tools built for s390x instead.
