Amazon EKS Workshop - Complements

EKS Cluster Access Management

This is a hot-patch for the Amazon EKS Workshop to cover leverage the recently announced Cluster Access Management API, that superseed the old method based on an integration between IAM and a in-cluster Kubernetes ConfigMap.

Steps to execute

  1. Let's create an IAM User, that will be used for exercising the EKS access management.
aws iam create-user --user-name lab-user
