lowing Gateway configuration sets up a proxy to act
as a load balancer exposing port 80 and 9080 (http), 443 (https),
9443(https) and port 2379 (TCP) for ingress. The gateway will be
applied to the proxy running on a pod with labels <code>app:
my-gateway-controller</code>. While Istio will configure the proxy to listen
on these ports, it is the responsibility of the user to ensure that
external traffic to these ports are allowed into the mesh.</p><pre><code class=language-yaml>apiVersion: networking.istio.i
