NGINX ingress controller

This page describes the legacy CDM implementation, which will be deprecated in an upcoming release. We strongly recommend that you transition to the current CDM implementation as soon as possible.

Use the NGINX ingress controller when you deploy the CDM.

Remember, the CDM is a reference implementation and not for production use. When you create a project plan, you’ll need to determine which ingress controller to use in production.

After you’ve finished deploying the CDM, you can use the CDM as a sandbox to explore deployment with a different ingress controller.

To deploy an NGINX ingress controller in a GKE cluster:

  1. Verify that you initialized your cluster by performing the steps in Kubernetes cluster creation.

    If you did not set up your cluster using this technique, the cluster might be missing some required configuration.

  2. Deploy the NGINX ingress controller in your cluster:

    $ /path/to/forgeops/bin/ingress-controller-deploy.sh --gke

. . .

  3. Check the status of the pods in the nginx namespace until all the pods are ready:

    $ kubectl get pods --namespace nginx
NAME                                          READY  STATUS    RESTARTS  AGE
ingress-nginx-controller-d794bb476-xxx6j      1/1    Running   0         4m38s

  4. Get the ingress controller’s external IP address:

    $ kubectl get services --namespace nginx
NAME                                 TYPE           CLUSTER-IP   EXTERNAL-IP      PORT(S)                      AGE
ingress-nginx-controller             LoadBalancer   10.4.6.154   35.203.145.112   80:30300/TCP,443:30638/TCP   58s
ingress-nginx-controller-admission   ClusterIP      10.4.4.9     <none>           443/TCP                      58s

    The ingress controller’s IP address should appear in the EXTERNAL-IP column. There can be a short delay while the ingress starts before the IP address appears in the kubectl get services command’s output; you might need to run the command several times.

  5. Add an entry to the /etc/hosts file to resolve the deployment FQDN used by the platform UIs and APIs. For example:

    ingress-ip-address prod.iam.example.com

    For ingress-ip-address, specify the external IP address of the ingress controller service in the previous command.
