The MultiClusterApplicationConfiguration custom resource is an envelope used to distribute core.oam.dev/v1alpha2/ApplicationConfiguration resources in a multicluster environment.

Here is a sample MultiClusterApplicationConfiguration that specifies an ApplicationConfiguration resource to create on the cluster named managed1. To deploy an example application that demonstrates a MultiClusterApplicationConfiguration, see Multicluster ToDo List.

The VerrazzanoManagedCluster custom resource is used to register a managed cluster with an admin cluster. Here is a sample VerrazzanoManagedCluster that registers the cluster named managed1. To deploy an example application that demonstrates a VerrazzanoManagedCluster, see Multicluster Hello World Helidon.

apiVersion: clusters.verrazzano.io/v1alpha1
kind: VerrazzanoManagedCluster
metadata:
  name: managed1
  namespace: verrazzano-mc
spec:
  description: "Managed Cluster 1"
  caSecret: ca-secret-managed1

Docs: VerrazzanoProject

The VerrazzanoProject custom resource is used to create the application namespaces and their associated security settings on one or more clusters. The namespaces are always created on the admin cluster. Here is a sample VerrazzanoProject that specifies a namespace to create on the cluster named managed1.

apiVersion: clusters.verrazzano.io/v1alpha1
kind: VerrazzanoProject
metadata:
  name: hello-helidon
  namespace: verrazzano-mc
spec:
  template:
    namespaces:
