Dangling Route Destination Host

The danglingroutedestinationhost vetter inspects the VirtualService(s) resources in your cluster and generates warning notes if any of the route destination hosts point to services which don't exist in the cluster. Any HTTP request routed to these hosts will return a 503 Service Unavailable response code as there is no backend service to fulfill the request.

Note that only route destination hosts ending in .svc.cluster.local and short names (host which don't contain any .) are inspected by this vetter as these hosts are implemented by services in the cluster.

It is recommended to either create the service(s) mentioned in the VirtualService(s) resources or update the VirtualService(s) to route to existing services in the cluster.

Notes Generated

• Destination host service(s) do not exist
