name: "Linkerd — Multi-Cluster Preview"
description: >-
  Installs linkerd-crds + linkerd-control-plane + linkerd-multicluster extension via Helm, verifies the multicluster Link and ServiceMirror CRDs are established, and authors a preview Link resource targeting a logical target cluster. No real cross-cluster traffic — this variant validates that the multicluster extension installs cleanly and that the CRD scaffolding is functional.
