Issue:
Migrate away from gcr.io/k8s-testimages repo
/kind bug
/priority important-soon
https://github.com/kubernetes/k8s.io/issues/1523

gcr.io/k8s-testimages is a legacy Google-owned GCR/AR repo. We should migrate to a community-owned AR registry.

See for example https://github.com/kubernetes/k8s.io/issues/1523#issuecomment-918396791

https://cs.k8s.io/?q=k8s-testimages&i=nope&literal=nope&files=&excludeFiles=&repos=kubernetes-sigs/prow

Hints from issue comments:
@ylink-lfs: /assign@BenTheElder: /lifecycle frozen
this has to be fixed, eventually these outdated images may not be available anymore.@BenTheElder: It looks like what remains is just test data.
