Pilotctl

Envoy is amazing ! And its dynamic control-plane too. However, if you are using Envoy as front-proxy, without any ingress or service mesh, you cannot easily leverage the control plane.

Pilotctl contains:

• Some examples of Envoy used as front-proxy, controled through (Istio) Pilot standalone in a Kubernetes environment
• a command line tool to debug and interact with Pilot and Envoy proxies. Credits: it mostly adapts code from istioctl & pilot.

Usage

# Check Envoys synchronization
pilotctl proxy-status

# Check Envoys configuration diff
pilotctl proxy-status <Envoy_pod_name> --port-forward=<Envoy_admin_port>

### Expected result:
# Clusters Match
# Listeners Match
# Routes Match (RDS last loaded at Mon, 08 Jul 2019 23:07:35 CEST)

# Go to Pilot Controlz dashboard
pilotctl dashboard controlz $(kubectl get pods -l app=pilot -o=jsonpath='{.items[0].metadata.name}')
# Or to Envoy admin dashboard
pilotctl dashboard envoy -p 8001 $(kubectl get pods -l app=envoy -o=jsonpath='{.items[0].metadata.name}')

# Display routes on a given Envoy Pod
pilotctl proxy-config routes --port-forward 8001 $(kubectl get pods -l app=envoy -o=jsonpath='{.items[0].metadata.name}')
