Target Clusters

ACM Foil uses ACM Placement to select managed clusters.

The active placement is:

Placement/acm-spo-policies/placement-spo-test

Selection Label​

Clusters opt in with:

spo=true

Label a managed cluster:

oc label managedcluster <cluster-name> spo=true --overwrite

Remove a cluster from placement:

oc label managedcluster <cluster-name> spo-

Cluster Set Binding​

The overlay binds the default ACM ManagedClusterSet into the policy namespace:

ManagedClusterSetBinding/acm-spo-policies/default

If a target cluster is in another cluster set, either move the cluster or add a matching ManagedClusterSetBinding.

Check a cluster set:

oc get managedcluster <cluster-name> \
  -o jsonpath='{.metadata.labels.cluster\.open-cluster-management\.io/clusterset}{"\n"}'

Validate Placement​

oc get placementdecision -n acm-spo-policies -o yaml

The decision should include the clusters that have spo=true and belong to a bound cluster set.
