NGINX Ingress Controller

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 an EKS 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 --eks

    "ingress-nginx" has been added to your repositories
    Release "ingress-nginx" does not exist. Installing it now.

    STATUS: deployed

  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-bb566bf7b-c9kmk   1/1     Running   0          2m45s
    ingress-nginx-controller-bb566bf7b-l6dz6   1/1     Running   0          2m45s
  4. Obtain the DNS name (shown under the EXTERNAL-IP column) of the load balancer :

    $ kubectl get services --namespace nginx
    NAME                                 TYPE           CLUSTER-IP     EXTERNAL-IP                                    PORT(S)                      AGE
    ingress-nginx-controller             LoadBalancer   10.100.43.88   ac5f2939. . .ca4.elb.us-east-1.amazonaws.com   80:30005/TCP,443:30770/TCP   62s
    ingress-nginx-controller-admission   ClusterIP      10.100.2.215   <none>                                         443/TCP                      62s
  5. Wait for a couple of minutes for the load balancer to be assigned the external IP address. Then, get the external IP addresses of the load balancer. For example:

    $ host ac5f2939. . .42d085.elb.us-east-1.amazonaws.com
    ac5f2939. . .42d085.elb.us-east-1.amazonaws.com has address 3.210.123.210

    The host command returns several IP addresses. You can use any of the IP addresses when you modify your local hosts file in the next step for evaluation purposes. You must create an appropriate entry in your DNS servers for production deployments.

  6. 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 of the ingress controller service in the previous command.
