Instance type

The instance type customization allows the user to specify the profile to use for control-plane and worker Machines.

This customization will be available when the provider-specific cluster configuration patch is included in the ClusterClass.

Example

To specify the instance type, use the following configuration:

apiVersion: cluster.x-k8s.io/v1beta1
kind: Cluster
metadata:
  name: <NAME>
spec:
  topology:
    variables:
      - name: clusterConfig
        value:
          controlPlane:
            aws:
              instanceType: m5.xlarge
      - name: workerConfig
        value:
          aws:
            instanceType: m5.2xlarge

Applying this configuration will result in the following value being set:

• control-plane AWSMachineTemplate:

  • spec:
      template:
        spec:
          instanceType: m5.xlarge
    

• worker AWSMachineTemplate:

  • spec:
      template:
        spec:
          instanceType: m5.2xlarge
