Guidance to create NLB creation using Ingress

0

I'm reaching out to the AWS community for assistance. Thank you!

I'm trying to set up an internal-facing NLB using Ingress. After applying the provided Ingress manifest, I've observed that the NLB endpoint appears to be empty. Are there any prerequisites I should ensure are in place before proceeding?

ingress-manifest.yaml

apiVersion: networking.k8s.io/v1 kind: Ingress metadata: name: ingress-service-nlb namespace: tresleai annotations: kubernetes.io/ingress.class: "nlb" #kubernetes.io/role/internal-elb: 1 service.beta.kubernetes.io/aws-load-balancer-type: "internal" service.beta.kubernetes.io/aws-load-balancer-internal: "true" service.beta.kubernetes.io/aws-load-balancer-nlb-target-type: "instance" service.beta.kubernetes.io/aws-load-balancer-ssl-cert: "arn:aws:acm:us-east-2:XYZ" service.beta.kubernetes.io/aws-load-balancer-ssl-ports: "443" service.beta.kubernetes.io/aws-load-balancer-ssl-negotiation-policy: "ELBSecurityPolicy-2016-08" nlb.ingress.kubernetes.io/security-groups: "sg-8edf9b29776" service.beta.kubernetes.io/aws-load-balancer-scheme: "internal" service.beta.kubernetes.io/aws-load-balancer-backend-protocol: tcp nlb.ingress.kubernetes.io/scheme: "internal" spec: rules: - host: service.test.ai http: paths: - path: / pathType: Prefix backend: service: name: test-service port: number: 80

I have added the IAM policy - Loadbalancer { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "elasticloadbalancing:CreateLoadBalancer", "elasticloadbalancing:DeleteLoadBalancer", "elasticloadbalancing:ModifyLoadBalancerAttributes", "elasticloadbalancing:RegisterTargets", "elasticloadbalancing:DeregisterTargets" ], "Resource": "" }, { "Effect": "Allow", "Action": [ "elasticloadbalancing:DescribeLoadBalancers", "elasticloadbalancing:DescribeTags" ], "Resource": "" } ] }

This has created Application type (internal facing) using Ingress.

I have made two changes, have added these two annotations

  • alb.ingress.kubernetes.io/load-balancer-type: nlb
    
  • kubernetes.io/ingress.class: "alb"
    

Wondering how to deploy an internal facing NLB using Ingress manifest file?

Ingress manifest file is used to create ALB (L7 load balancer), not NLB (L4 load balancer).

You can read more about it here and here.

To create (internal) NLB you need to use the Service manifest instead with type: LoadBalancer. for example:

apiVersion: v1
kind: Service
metadata:
  name: my-internal-nlb-service
  annotations:
    service.beta.kubernetes.io/aws-load-balancer-type: external
    service.beta.kubernetes.io/aws-load-balancer-scheme: "internal"  # Make the NLB internal
spec:
  type: LoadBalancer
  ports:
  - port: 80
    targetPort: 80
    protocol: TCP
  selector:
    app: my-app
