Deploy NGINX Ingress Controller

In this section you will configure and deploy the NGINX Ingress Controller and expose it using an external network load balancer.


  1. Go to your GitOps repository, inside your rok-tools management environment:

    root@rok-tools:~# cd ~/ops/deployments
  2. Edit rok/nginx-ingress-controller/overlays/deploy/kustomization.yaml and use service-gclb as base, instead of the default ingress-alb:

    bases: #- ../ingress-alb #- ../service-elb #- ../service-azurelb - ../service-gclb
  3. Edit rok/nginx-ingress-controller/overlays/deploy/kustomization.yaml and enable only the service-gclb patch, instead of the default ingress-alb and service-alb:

    patches: #- path: patches/ingress-alb.yaml #- path: patches/service-alb.yaml #- path: patches/service-elb.yaml #- path: patches/service-azurelb.yaml - path: patches/service-gclb.yaml
  4. Enable the firewall in your Google Cloud Load Balancer and allow access only to specific CIDRs. Edit rok/nginx-ingress-controller/overlays/deploy/patches/service-gclb.yaml and set loadBalancerSourceRanges to the desired trusted CIDRs. Leave the default value of if you want to allow access for everyone:

    spec: loadBalancerSourceRanges: - ""
  5. Commit your changes:

    root@rok-tools:~/ops/deployments# git commit -am "Expose NGINX Ingress Controller with a Google Cloud Load Balancer"
  6. Deploy NGINX Ingress Controller:

    root@rok-tools:~/ops/deployments# rok-deploy --apply rok/nginx-ingress-controller/overlays/deploy


  1. Verify that NGINX Ingress Controller is up-and-running. Check pod status and verify field STATUS is Running and field READY is 1/1:

    root@rok-tools:~/ops/deployments# kubectl -n ingress-nginx get pods NAME READY STATUS RESTARTS AGE ingress-nginx-controller-7f74f657bd-ln59l 1/1 Running 0 1m
  2. Verify that the Load Balancer Service has an external IP:

    root@rok-tools:~/ops/deployments# kubectl -n ingress-nginx get service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE ingress-nginx LoadBalancer 80:30099/TCP,443:30719/TCP 1m


You have successfully deployed the NGINX Ingress Controller and exposed it using a Google Cloud Load Balancer.
