Deploy NGINX ingress controller on the Kubernetes cluster

After you create and deploy your Kubernetes secrets, set up the NGINX ingress controller. This page explains how to use the preconfigured Helm values to install the controller, verify that the AWS network load balancer is active, and create the DNS records your cluster needs to route traffic. After you complete these steps, configure Cert Manager to manage TLS certificates for your cluster.

Install the NGINX ingress controller

The values in charts/nginx-ingress/values.yaml (part of the nbs-helm-vX.Y.Z zip file) are preconfigured to set up Prometheus metrics scraping and to instruct the NGINX controller to create an AWS network load balancer instead of a classic load balancer.

1. Install the NGINX ingress controller:

   helm upgrade --install ingress-nginx ingress-nginx --repo https://kubernetes.github.io/ingress-nginx -f ./nginx-ingress/values.yaml --namespace ingress-nginx --create-namespace --version 4.11.5
   

   

2. Monitor the deployment status:

   kubectl --namespace ingress-nginx get services -o wide -w ingress-nginx-controller
   

   Use Ctrl+C to exit if the command is still running.

3. In the AWS load balancers console, confirm a network load balancer was created and its target groups point to the EKS cluster.

4. Confirm at least one NGINX controller pod is running:

   kubectl get pods -n=ingress-nginx
   

Create DNS records

Create A records in your DNS service (for example, Route 53) pointing the following subdomains to the active network load balancer provisioned above. Replace example_domain.com with your domain name.

NiFi has known security vulnerabilities. Only add a NiFi DNS entry if you need to administer it directly. Omit it otherwise.

Subdomain	Template	Example
NBS (main domain)	site_name.example_domain.com	fts3.nbspreview.com
NBS 6 (classic)	app-classic.site_name.example_domain.com	app-classic.fts3.nbspreview.com
NBS 7 (modern)	app.site_name.example_domain.com	app.fts3.nbspreview.com
NiFi (optional)	nifi.site_name.example_domain.com	nifi.fts3.nbspreview.com
Data Ingestion	data.site_name.example_domain.com	data.fts3.nbspreview.com
