Kubernetes v1.24 has been released, find the changelog here: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.24.md

Work can be started and pushed to the kubernetes-v1.24 branch. There should be similar branches in the provider extension repositories in case the work has been started already.

Tasks

Hyperkube

• hyperkube: https://concourse.ci.gardener.cloud/teams/gardener/pipelines/hyperkube-master/jobs/master-build-hyperkube-images-job/builds/13
  • Build new images for v1.24

Gardener

• gardener: Support for Kubernetes v1.24 #6023
  • Good to know/no action required
    • dockershim is now fully removed from kubelet, but we already only allow containerd for shoots >= 1.23, so we should be prepared
    • The LegacyServiceAccountTokenNoAutoGeneration feature gate is beta, and enabled by default. (ref no auto-generation of secret-based service account token kubernetes/kubernetes#108309)
  • Release-independent tasks
    • Allow instantiating v1.24 Kubernetes clients and update README.md and docs/usage/supported_k8s_versions.md
    • Update feature gates in https://github.com/gardener/gardener/blob/master/pkg/utils/kubernetes/featuregates.go
    • Update KCM controllers in https://github.com/gardener/gardener/blob/master/pkg/operation/botanist/component/shootsystem/shootsystem.go
    • Bump used Kubernetes version for local shoot and local e2e test
  • Release-specific tasks
    • The .spec.loadBalancerIP field is deprecated and will be removed in the future. Users should use provider-specific annotations when available (ref Deprecate Service.Spec.LoadBalancerIP kubernetes/kubernetes#107235). We have several usages in our code, do we need adaptation?
    • The --pod-infra-container-image kubelet flag is deprecated and will be removed in future releases (ref Mark pod-infra-container-image flag as deprecated kubernetes/kubernetes#108045)
    • The metadata.selfLink field is deprecated since 1.20 (now KAPI does not populate it anymore, ref Graduate RemoveSelfLink to Stable kubernetes/kubernetes#107527). We have some usages in pkg/registry in our code, probably we should remove them as well
