Use Kubernetes v1.34 and Kind v0.30 by default

[nixpanic]

After a recent Docker update, the CI jobs fail during kind build node-image. This has been addressed in kubernetes/kubernetes#135575, but only for the maintained Kubernetes releases.

It seems release-tools/prow.sh uses Kubernetes v1.22.0, which isn't supported anymore, and hence not fixed. Updating the Kubernetes version in prow.sh and using the most recent Kind version should make the CI jobs succeed again.

Examples of jobs that failed:

• external-provisioner: https://prow.k8s.io/view/gs/kubernetes-ci-logs/pr-logs/pull/kubernetes-csi_external-provisioner/1440/pull-kubernetes-csi-external-provisioner-unit/1998009125761454080
• external-resizer: https://prow.k8s.io/view/gs/kubernetes-ci-logs/pr-logs/pull/kubernetes-csi_external-resizer/544/pull-kubernetes-csi-external-resizer-1-34-on-kubernetes-1-34/1997978865183494144

NONE

So no sidecar should be using v1.22 kubernetes anymore. The defaults in release-tools are replaced by sidecars or the test-infra YAMLs. The error:

is coming while building v1.34 kube-build image right? I am fine with upgrading kind version but we can't harcode to v1.34 because technically we still have to support v1.33 and v1.32 .

If we must bump kubernetes we can bump to v1.32 or v1.31 or something, but I am not sure if that is the root cause of the problem.

The fix is in a build script from the k/k repository. I think the falling jobs do checkout k/k v1.22.0 which contains an old version of the script.

See kubernetes/kubernetes#135576 for the ip-address parsing change for the new Docker version.

Can you test this change by submitting a test PR to external-provisioner and external-resizer?

Sure!

• Rebase release-tools to use Kubernetes v1.34 by default external-resizer#549
• Rebase release-tools to use Kubernetes v1.34 by default external-provisioner#1455

Both passed all tests now 🥳

Okay lets merge this. We can come back to it, if it still fails. Thanks for opening verification PRs for external-resizer repos etc.
