Configuring multi-cluster links

Buoyant Cloud provides visibility into your Linkerd multi-cluster setup.

When Buoyant Cloud receives a multi-cluster Link object from an agent, it automatically associates its target cluster with a known cluster in Buoyant Cloud. It matches based on the cluster name, specified in spec.TargetClusterName in the multi-cluster Link object. If a match is not found, Buoyant Cloud will warn you. To resolve this, you can change the cluster name in Buoyant Cloud to match spec.TargetClusterName, or you can manually specify a annotation on the Link object. For example, if your Link object is named east, but in Buoyant Cloud the cluster is named k8s-east, you can annotate it with:

kubectl --context=west annotate -n linkerd-multicluster links/east
