Managed Cluster

A Managed Cluster resource (ManagedCluster) represents a cluster managed by a centralized management plane with a shared Elasticsearch. The management plane provides central control of the managed cluster and stores its logs.

Calico Cloud supports connecting multiple Calico Cloud clusters as describe in the [Multi-cluster management] installation guide.

For kubectl commands, the following case-insensitive aliases may be used to specify the resource type on the CLI: managedcluster,managedclusters, managedcluster.projectcalico.org, managedclusters.projectcalico.org as well as abbreviations such as managedcluster.p and managedclusters.p.

Sample YAML

apiVersion: projectcalico.org/v3
kind: ManagedCluster
metadata:
  name: managed-cluster
spec:
  operatorNamespace: tigera-operator
