Migrate Classic Loadbalancer to Application Loadbalancer in EKS - amazon-web-services

Question

I am trying to migrate my CLB to ALB. I know there is a direct option on the AWS loadbalancer UI console to do a migration. But I don't want to use that. I have a service file which deploys classic loadbalancer on EKS using kubectl.
apiVersion: v1
kind: Service
metadata:
annotations: {service.beta.kubernetes.io/aws-load-balancer-connection-idle-timeout: '3600',
service.beta.kubernetes.io/aws-load-balancer-type: classic}
name: helloworld
spec:
ports:
- {name: https, port: 8443, protocol: TCP, targetPort: 8080}
- {name: http, port: 8080, protocol: TCP, targetPort: 8080}
selector: {app: helloworld}
type: LoadBalancer
I want to convert it into ALB. I tried the following approach but not worked.
apiVersion: v1
kind: Service
metadata:
name: helloworld
spec:
ports:
- {name: https, port: 8443, protocol: TCP, targetPort: 8080}
- {name: http, port: 8080, protocol: TCP, targetPort: 8080}
selector: {app: helloworld}
type: NodePort

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: helloworld
annotations:
kubernetes.io/ingress.class: alb
alb.ingress.kubernetes.io/scheme: internet-facing
alb.ingress.kubernetes.io/tags: Environment=dev,Team=app**
spec:
rules:
- host: "*.amazonaws.com"
http:
paths:
- path: /echo
pathType: Prefix
backend:
service:
name: helloworld
port:
number: 8080
It has not created any loadbalancer. When I did kubectl get ingress, It showed me the ingress but it has no address. What am I doing wrong here?

Answer 1

your Ingress file seems to be correct,
for having ALB installed automatically from an Ingress you should install the AWS Load Balancer Controller which manages AWS Elastic Load Balancers for a Kubernetes cluster.
You can follow this and then verify that it is installed correctly:
kubectl get deployment -n kube-system aws-load-balancer-controller
apply:
kubectl apply -f service-ingress.yaml
and verify that your ALB, TG, etc are created:
kubectl logs deploy/aws-load-balancer-controller -n kube-system --follow
