[NOTICE] Kubernetes v1.23 CI builds served only from community-owned infrastructure

[Aaron Crickenberger]

Hi all

tl;dr Kubernetes v1.22 is the last release to publish CI builds to gs://kubernetes-release-dev and gcr.io/kubernetes-ci-images.  From v1.23 forward, CI builds are published solely to gs://k8s-release-dev and gcr.io/k8s-staging-ci-images.  All repos and docs have been updated accordingly.

Greetings from one of your friendly WG K8s Infra organizers!

It's taken us 5 releases to get here, but we're excited to announce that going forward, all CI builds of Kubernetes are now hosted solely on community-owned infrastructure!  The previous locations were hosted by google.com (gs://kubernetes-release-dev, gcr.io/kubernetes-ci-images), and the new locations are hosted by kubernetes.io (gs://k8s-release-dev, gcr.io/k8s-staging-ci-images)

How we got here:

- v1.17 was the first release that had CI builds of kubernetes land in gs://k8s-release-dev/ci and gs://kubernetes-release-dev/ci simultaneously
- v1.18 was the first release that cluster-api and kubeadm started defaulting to gcr.io/k8s-staging-ci-images instead of gcr.io/kubernetes-ci-images
- v1.20 was the last release that had CI builds land in gs://kubernetes-release-dev/ci-cross
- v1.22 is the last release to have CI builds of kubernetes land in gs://kubernetes-release-dev and gcr.io/kubernetes-ci-images.  All project repos and jobs were migrated to use community-hosted locations.

Next steps:

- If you want to consume CI builds of Kubernetes v1.23 onward, please use:

  - https://dl.k8s.io if using an HTTP-based tool like curl or wget

  - gs://k8s-release-dev if using gsutil (or some other GCS tool)

  - gcr.io/k8s-staging-ci-images if using a container image based setup

- Currently supported versions of Kubernetes will continue to publish CI builds to the google.com-hosted locations

- As jobs age out due to the Kubernetes version support policy, we expect to see traffic diminish

- When there are no more builds hosted in gs://kubernetes-release-dev, it will be decommissioned, along with gcr.io/kubernetes-ci-images
