This document contains important upgrade notes for upgrading from KubeOne 1.13 to v1.14. For the complete changelog, please check the complete v1.14.0 changelog on GitHub.
Make sure to familiarize yourself with the known issues in KubeOne 1.13 before upgrading by checking the Known Issues document.
KubeOne 1.14 introduces support for Kubernetes 1.36. Support for Kubernetes 1.33 has been removed as this release already reached End-of-Life (EOL).
If you have a Kubernetes cluster running 1.33 or earlier, you need to update to Kubernetes 1.34 or newer using KubeOne 1.13. For more information, check out the Kubernetes compatibility document.
The minimum kernel version for Kubernetes 1.34 clusters is 5.2. It’s recommended to use a kernel version 5.13 or later.
More information at https://kubernetes.io/docs/reference/node/kernel-version-requirements/.
All CCM/CSI migration tooling has been removed. The kubeone migrate to-ccm-csi command is now a no-op (kept only for backward compatibility) since Kubernetes has fully moved on from in-tree cloud providers and CSI migration. If any of your clusters are still running with the in-tree cloud provider (.cloudProvider.external: false) and haven’t completed the CCM/CSI migration, complete it using KubeOne v1.13 or earlier before upgrading to v1.14. See #4096.
