Upgrade the cluster to a new Kubernetes version

You are viewing documentation for Kubernetes 1.34, Cluster Stack release hetzner-apalla-1-34-v3.

Update your Cluster Stack release first

To upgrade to Kubernetes 1.35, first update your cluster to Cluster Stack release hetzner-apalla-1-34-v11 by following this guide: Updating the cluster with same Kubernetes version . Once that update is complete, return to this guide to upgrade your Kubernetes version.

Not sure which version your cluster uses?

Check the Kubernetes version and Cluster Stack of your cluster.

Note

Starting from hetzner-apalla-1-35-v1, Hetzner node image builds are no longer required. Because of that, we require a common SSH key for both bare metal and cloud servers. If you did not use the same SSH key when doing the Hetzner account preparation , please change the secrets to ensure you have a single SSH key.

Update cluster

Move a Syself Autopilot cluster to a newer Cluster Stack release on the same Kubernetes minor version: make the release available, then point the cluster at it.
