To check whether Ingress Gateway has deployed successfully
1. Port-forward Envoy pod 
  PowerShell:
  $POD_NAME=(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "eks-app-mesh-gateway.name" . }},release={{ .Release.Name }}" -o jsonpath="{.items[0].metadata.name}")
  "To check gateway configuration, visit http://127.0.0.1:9901/listeners, http://127.0.0.1:9901/clusters and http://127.0.0.1:9901/config_dump"
  kubectl port-forward $POD_NAME 9901:9901

  Bash:
  export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "eks-app-mesh-gateway.name" . }},release={{ .Release.Name }}" -o jsonpath="{.items[0].metadata.name}")
  echo "To check gateway configuration, visit http://127.0.0.1:9901/listeners, http://127.0.0.1:9901/clusters and http://127.0.0.1:9901/config_dump"
  kubectl port-forward $POD_NAME 9901:9901
      
2. Browse to:
  - http://127.0.0.1:9901/listeners - This page should not be blank *after first GatewayRoute is created*
  - http://127.0.0.1:9901/clusters - After first GatewayRoute is created, this page should contain information about nodes *other than 127.0.0.1*
  - http://127.0.0.1:9901/config_dump - Scroll down to see most consequential data *after first GatewayRoute is created*
