Terraform module to provision an EKS cluster on AWS.
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!
The module provisions the following resources:
- EKS cluster of master nodes that can be used together with the terraform-aws-eks-workers module to create a full-blown cluster
- IAM Role to allow the cluster to access other AWS services
- Security Group which is used by EKS workers to connect to the cluster and kubelets and pods to receive communication from the cluster control plane (see terraform-aws-eks-workers)
- The module generates
kubeconfigconfiguration to connect to the cluster usingkubectl
Module usage examples:
- examples/complete - complete example
- terraform-root-modules/eks - Cloud Posse's service catalog of "root module" invocations for provisioning reference architectures
- terraform-root-modules/eks-backing-services-peering - example of VPC peering between the EKS VPC and backing services VPC
