AWS ElasticIP to nginx ingress controller EKS?

Question

I have a simple task, but it is not solved even after studying dozens of articles.

There is a simple AWS EKS cluster created from a demo template using eksctl, ElasticIP and installed without changes https://bitnami.com/stack/nginx-ingress-controller/helm

There is a domain https://stage.mydomain.com which I want to forward to ElasticIP, using DNS A-record, on AWS EKS nginx ingress controller 1234567890.eu-central-1.elb.amazonaws.com so that all the services of my cluster are available at this ElasticIP address.

I tried through Load Balancer and Network Balancer, but it doesn't work.

Is there a proven article or sequence of actions for solving this problem and with this set of services?

Yes that's common in AWS articles also NLD value coming like this way only

https://aws.amazon.com/blogs/opensource/network-load-balancer-nginx-ingress-controller-eks/

In the above article installing the NGINX controller using the NLB as backend which providing the IP the same way.

In this case you can add the DNS with A or CNAME

Once your ingress controller setup is done you will get LB endpoint you have to add this to DNS as A record or CNAME

this will forward the request to the cluster.

Now inside the cluster, you have to create the ingress using applying the YAML

https://kubernetes.io/docs/concepts/services-networking/ingress/

ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: minimal-ingress
  annotations:
    nginx.ingress.kubernetes.io/rewrite-target: /
spec:
  rules:
  - http:
      paths:
      - path: /testpath
        pathType: Prefix
        backend:
          service:
            name: test
            port:
              number: 80

For NLB in you can add the annotation to service

**service.beta.kubernetes.io/aws-load-balancer-type: nlb**


apiVersion: v1
kind: Service
metadata:
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-backend-protocol: tcp
    service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: '60'
    service.beta.kubernetes.io/aws-load-balancer-cross-zone-load-balancing-enabled: 'true'
    service.beta.kubernetes.io/aws-load-balancer-type: nlb
  labels:
    helm.sh/chart: ingress-nginx-2.0.3
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/version: 0.32.0
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/component: controller
  name: ingress-nginx-controller
  namespace: ingress-nginx
spec:
  type: LoadBalancer
  externalTrafficPolicy: Local
  ports:
    - name: http
      port: 80
      protocol: TCP
      targetPort: http
    - name: https
      port: 443
      protocol: TCP
      targetPort: https
  selector:
    app.kubernetes.io/name: ingress-nginx
    app.kubernetes.io/instance: ingress-nginx
    app.kubernetes.io/component: controller
