Answer by Recoba20 for Cannot configure node group in new EKS cluster due to no Node IAM role found

This is actually pretty well described in the docs.

Before you create worker nodes, you must create an IAM role with thefollowing IAM policies:

AmazonEKSWorkerNodePolicy

AmazonEKS_CNI_Policy

AmazonEC2ContainerRegistryReadOnly

Also you need to make sure that this role could be assumed by EKS.
