Error to deploy the Kubernetes Dashboard on EKS using terraform

Question

I have used the terraform to setup the EKS cluster and worker nodes, they are all working, However, when I try to deploy the K8S dashboard on the cluster by following the documentation on AWS: https://docs.aws.amazon.com/eks/latest/userguide/dashboard-tutorial.html

I got the error below when I was trying to access the localhost:8001

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

When I access the pods info, this is what I got:

I have noticed that the Kubernetes-dashboard pod is stuck at ContainerCreating status.

I also check the K8s Dashboard pod info

Events:

I did my research about the error, it is either too old or not working in my case. Any helps plz !

I got this error `Error from server (NotFound): pods "kubernetes-dashboard-65c76f6c97-kgmmr" not found` . That is so strange since the pod name does exist. — Akira, Apr 16 '19 at 23:39
`kubectl describe po -n kube-system` add the namespace as well — vins, Apr 16 '19 at 23:40
The error message is too to display on here, I am going to edit my post — Akira, Apr 16 '19 at 23:44

Your problem seems to be with the CNI. You might have to upgrade.

Please check here for the solution. https://docs.aws.amazon.com/eks/latest/userguide/cni-upgrades.html

I have updated the VPC, however, I still cannot connect it. :( – Akira Apr 16 '19 at 23:56
You mean you upgraded the CNI to the latest version? – vins Apr 16 '19 at 23:58
Ya, I upgraded the CNI to the latest version. However, K8S dashboard pod is still stuck at the ContainerCreating status – Akira Apr 17 '19 at 00:00
did you take a look at your security groups? do you allow all the ports from the instances which has the same security group? – vins Apr 17 '19 at 00:39
this is the website I am using to build up my terraform code ```https://www.iheavy.com/2018/07/31/how-to-setup-an-amazon-eks-demo-with-terraform/```. I haven't change it much, I am very new to terraform. – Akira Apr 17 '19 at 16:15
