NGiNX Ingress Controller k8s - Layer 7 (L4/L7) Load Balancer (outside traffic)

Route/load balance traffic from external clients to the Deployment.

Deploying the NGINX Ingress Controller with Helm

1. Create Deployment and Service via Helm helm install --name nginx-ingress stable/nginx-ingress --set rbac.create=true --set controller.publishService.enabled=true
2. Check that the service is running (as daemonset) kubectl get svc nginx-ingress-default-backend ClusterIP 10.47.252.194 <none> 80/TCP nginx-ingress-controller LoadBalancer 10.47.248.164 35.198.179.156 80:30313/TCP,443:30463/TCP
3. Configure Ingress Resources to use NGINX Ingress Controller Note: Ingress Resource object is a collection of L7 rules for routing inbound traffic to Kubernetes Services. https://github.com/GoogleCloudPlatform/community/blob/master/tutorials/nginx-ingress-gke/ingress-resource.yaml

apiVersion: extensions/v1beta1

4. Apply resource kubectl apply -f ingress-resource.yaml
5. Verify that it has been created kubectl get ingress
6. Call it from the outside http://external-ip-of-ingress-controller/hello
