Step 3: Install Advanced Cluster Management

Install Red Hat Advanced Cluster Management (ACM) on the hub cluster to manage the provisioning of the POC cluster.

Set the Kubeconfig

export KUBECONFIG=~/ocp-installer/sno/auth/kubeconfig

Install the ACM Operator

Create the namespace:

oc create namespace open-cluster-management

Create the OperatorGroup:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1
kind: OperatorGroup
metadata:
  name: acm-operator-group
  namespace: open-cluster-management
spec:
  targetNamespaces:
    - open-cluster-management
EOF

Create the Subscription:

cat <<EOF | oc apply -f -
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
  name: advanced-cluster-management
  namespace: open-cluster-management
spec:
  channel: release-2.13
  installPlanApproval: Automatic
  name: advanced-cluster-management
  source: redhat-operators
  sourceNamespace: openshift-marketplace
EOF

Wait for the operator to be ready:

oc wait --for=condition=Available deployment/multiclusterhub-operator \
  -n open-cluster-management --timeout=300s

Create the MultiClusterHub

cat <<EOF | oc apply -f -
apiVersion: operator.open-cluster-management.io/v1
kind: MultiClusterHub
metadata:
  name: multiclusterhub
  namespace: open-cluster-management
spec: {}
EOF

Wait for ACM to be fully deployed:

oc wait --for=condition=Complete multiclusterhub/multiclusterhub \
  -n open-cluster-management --timeout=600s

Verify ACM

oc get multiclusterhub -n open-cluster-management
