I am a bit very stuck on the step of Launching worker node in the AWS EKS guide. And to be honest, at this point, I don't know what's wrong. When I do kubectl get svc, I get my cluster so that's good news. I have this in my aws-auth-cm.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: aws-auth
  namespace: kube-system
data:
  mapRoles: |
    - rolearn: arn:aws:iam::Account:role/rolename
      username: system:node:{{EC2PrivateDNSName}}
      groups:
        - system:bootstrappers
        - system:nodes

Here is my config in .kube

apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: CERTIFICATE
    server: server
  name: arn:aws:eks:region:account:cluster/clustername
contexts:
- context:
    cluster: arn:aws:eks:region:account:cluster/clustername
    user: arn:aws:eks:region:account:cluster/clustername
  name: arn:aws:eks:region:account:cluster/clustername
current-context: arn:aws:eks:region:account:cluster/clustername
kind: Config
preferences: {}
users:
- name: arn:aws:eks:region:account:cluster/clustername
  user:
    exec:
      apiVersion: client.authentication.k8s.io/v1alpha1
      args:
      - token
      - -i
      - clustername
      command: aws-iam-authenticator.exe

I have launched an EC2 instance with the advised AMI.

Some things to note :

• I launched my cluster with the CLI,
• I created some Key Pair,
• I am not using the Cloudformation Stack,
• I attached those policies to the role of my EC2 : AmazonEKS_CNI_Policy, AmazonEC2ContainerRegistryReadOnly, AmazonEKSWorkerNodePolicy.

It is my first attempt at kubernetes and EKS, so please keep that in mind :). Thanks for your help!
