  • Navigate to your project
  • Select Infrastructure -> Clusters
  • Click on the cluster card
  • Click the "Configuration" tab
  • View the current "Control Plane Version" and the "Node Version"

Verify Cluster Version

  • Click on the gear icon of the cluster
  • Select "Upgrade Cluster"
  • Select a more recent version for the "Control Plane Version" and the "Worker Node Version"
  • Click "Upgrade"

Step 1: Upgrade Cluster

In this step, you will upgrade the kubernetes version of the cluster.

Confirm the current cluster versions

  • Navigate to your project
  • Select Infrastructure -> Clusters
  • Click on the "Kubectl" button on the cluster card
  • Type "get nodes"

Verify Cluster Version

You will upgrade the cluster version by updating the "cluster.yaml" file and running "rctl apply" on the file.

Change the cluster versions in the "cluster.yaml" file to "v1.23.5" and save the file.

 controlPlane:
   machineCount: 1
   version: v1.23.5

 workerNodes:
   machineCount: 1
   version: v1.23.5
  • Open a terminal (on macOS/Linux) or Command Prompt (Windows)
  • Navigate to the folder where you stored the "cluster.yaml" file
  • Type the command below to upgrade up the cluster versions
rctl apply -f cluster.yaml

The upgrade operation will begin. Note, this operation can take several minutes.
