• Part of umbrella to migrate kubernetes e2e test images/registries to community-owned infrastructure: Registries used in k/k CI should be on Kubernetes Community infra #1458
• Companion issue to Use k8s.gcr.io/e2e-test-images instead of gcr.io/kubernetes-e2e-test-images for e2e test images kubernetes#96770

We should migrate away from the google.com-owned gcr.io/kubernetes-e2e-test-images and instead use the community-owned k8s.gcr.io/e2e-test-images repository.

Once we have done so, we should:

• announce a deprecation window: https://groups.google.com/g/kubernetes-dev/c/jIrBjnw3cDg
• flag project for deletion post-deprecation: post-deprecation-window: turn down kubernetes-e2e-test-images GCP project #3112
