     1  # Accessing the Envoy Administration Interface
     2  
     3  Getting access to the Envoy [administration interface][1] can be useful for diagnosing issues with routing or cluster health.
     4  
     5  The Envoy administration interface is bound by default to `http://127.0.0.1:9001`.
     6  To access it from your workstation use `kubectl port-forward` like so:
     7  
     8  ```sh
     9  # Get one of the pods that matches the Envoy daemonset
    10  ENVOY_POD=$(kubectl -n projectcontour get pod -l app=envoy -o name | head -1)
    11  # Do the port forward to that pod
    12  kubectl -n projectcontour port-forward $ENVOY_POD 9001
    13  ```
    14  
    15  Then navigate to `http://127.0.0.1:9001/` to access the administration interface for the Envoy container running on that pod.
