Changelog for Kubernetes 1.30

Versions

The deployed Kubernetes version varies based on when your cluster is deployed. We try deploying cluster using the latest patch release of Kubernetes.

Current release is Kubernetes 1.30.1

Major changes

• New default storageclass v2-1k
• New clusters will only have v2 storage classes available.
• nodelocaldns will be removed for all clusters where it’s still deployed. This change affects only clusters created prior to Kubernetes 1.26, as the feature was deprecated in that version.
• Clusters created before Kubernetes 1.26 will have their public domains removed. In Kubernetes 1.26, we migrated to using a LoadBalancer and its IP instead. If you are using an old kubeconfig with an active domain, please fetch a new one.

APIs removed in Kubernetes 1.32

More details can be found in Kubernetes official documentation.

• Flow control flowcontrol.apiserver.k8s.io/v1beta3. The replacement flowcontrol.apiserver.k8s.io/v1 was implemented in Kubernetes 1.29
• The 4k, 8k, 16k, and v1-dynamic-40 storage classes will be removed. Please migrate to the v2 storage classes, which have been available since Kubernetes 1.26 and have been the default since Kubernetes 1.30.
