external-ip remains pending on controller-service after installation of Nginx Ingress Controller on-CodePudding

I'm following the quickstart guide https://kubernetes.github.io/ingress-nginx/deploy/#aws to install it on an aws eks cluster

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/aws/deploy.yaml

When I then check the service I can see that it is pending:

 kubectl get svc --namespace=ingress-nginx
NAME                                 TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)                      AGE
ingress-nginx-controller             LoadBalancer   10.100.64.86     <pending>     80:31323/TCP,443:31143/TCP   2d5h

The service generated seems ok, with valid annotations:

 kubectl describe svc  ingress-nginx-controller --namespace=ingress-nginx

Not sure how to troubleshoot or fix

CodePudding user response：

what worked for me was to download the installation file (https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/aws/deploy.yaml) and add an annotation to the controller-service and then reapply the installation.

service.beta.kubernetes.io/aws-load-balancer-internal: "true"

not sure why it doesnt work as-is.

CodePudding user response：

i would suggest try applying this changes,

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-0.32.0/deploy/static/provider/aws/deploy.yaml

The change that you have is for internal load balancer that wont give you a public exposed IP or Loabalancer.

service.beta.kubernetes.io/aws-load-balancer-internal: "true"

You can follow this Guide and this will create the NLB loadbalancer for you and the ingress tutorial also.
