MeshLoadBalancingStrategies: Route to the local zone instances equally - Policy

Route to the local zone instances equally

In this example, when a user sends a request to the backend service, the request is routed equally to all instances in the local zone. If there are no instances in the local zone, the request will fail because there is no cross zone traffic.

Configuration

I am using MeshService

apiVersion: kuma.io/v1alpha1
kind: MeshLoadBalancingStrategy
metadata:
  name: local-zone-affinity-backend
  namespace: kuma-demo
  labels:
    kuma.io/mesh: default
spec:
  to:
  - targetRef:
      kind: MeshService
      name: backend_kuma-demo_svc_8080
    default:
      localityAwareness:
        localZone: {}

Please adjust konnect_mesh_control_plane.my_meshcontrolplane.id and konnect_mesh.my_mesh.name according to your current configuration.
