Terraform module to create and apply a Kubernetes ConfigMap to map AWS IAM roles to Kubernetes users/groups.
This will configure clusters managed by kops to use aws-iam-authenticator,
allowing to use AWS IAM credentials to authenticate to a Kubernetes cluster.
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!
