How to use EKS with AWS SSO

Question

Hi,  
  
We would like to give users permissions to use EKS using their AWS SSO usernames. I'm aware of the aws-iam-authenticator and eksctl, but not quite sure how to make them all work together with SSO rather than an IAM username.  
  
Thanks

Hi,  
  
Amazon EKS uses IAM to provide authentication to your Kubernetes cluster (through the aws eks get-token command, available in version 1.16.156 or later of the AWS CLI, or the AWS IAM Authenticator for Kubernetes), but it still relies on native Kubernetes Role Based Access Control (RBAC) for authorization. This means that IAM is only used for authentication of valid IAM entities. All permissions for interacting with your Amazon EKS cluster’s Kubernetes API is managed through the native Kubernetes RBAC system.

IMHO this topic deserves a specific documentation page. AWS SSO uses some weirdly formatted role arns, and I've never been able to set this stuff up so that SSO users can access EKS using kubectl.   
  
Pretty crazy that such an essential thing as kubectl access using SSO roles isn't properly documented
