Accessing the Envoy Administration Interface

Getting access to the Envoy administration interface can be useful for diagnosing issues with routing or cluster health.

The Envoy administration interface is bound by default to http://127.0.0.1:9001. To access it from your workstation use kubectl port-forward like so:

# Get one of the pods that matches the Envoy daemonset
ENVOY_POD=$(kubectl -n projectcontour get pod -l app=envoy -o name | head -1)
# Do the port forward to that pod
kubectl -n projectcontour port-forward $ENVOY_POD 9001

Then navigate to http://127.0.0.1:9001/ to access the administration interface for the Envoy container running on that pod.
