Via clusterctl

Add the following to your clusterctl.yaml file, which is normally found at ${XDG_CONFIG_HOME}/cluster-api/clusterctl.yaml (or ${HOME}/cluster-api/clusterctl.yaml). See clusterctl configuration file for more details. If the providers section already exists, add the entry and omit the providers key from this block below:

providers:
  - name: "caren"
    url: "https://github.com/nutanix-cloud-native/cluster-api-runtime-extensions-nutanix/releases/v0.15.0/runtime-extension-components.yaml"
    type: "RuntimeExtensionProvider"

Now we can deploy CAREN and other necessary providers (update infrastructure providers for your needs), leaving all configuration values blank as we will specify these when creating clusters:

env CLUSTER_TOPOLOGY=true \
    EXP_RUNTIME_SDK=true  \
    EXP_CLUSTER_RESOURCE_SET=true  \
    NUTANIX_ENDPOINT= NUTANIX_PASSWORD= NUTANIX_USER=  \
    AWS_B64ENCODED_CREDENTIALS=  \
    clusterctl init \
      --infrastructure docker,nutanix:v1.4.0,aws \
      --addon helm \
      --runtime-extension caren:v0.15.0 \
      --wait-providers
