An AWS CloudFormation resource provider for the management of helm 3 resources in EKS and self-managed Kubernetes clusters.

An IAM role is used by CloudFormation to execute the Helm resource type handler code. A CloudFormation template to create the exeecution role is available here

EKS clusters use IAM to allow access to the kubernetes API, as the CloudFormation resource types in this project interact with the kubernetes API, the IAM execution role must be granted access to the kubernetes API. This can be done in one of two ways:

• Create the cluster using CloudFormation: Currently there is no native way to manage EKS auth using CloudFormation (+1 this GitHub issue to help prioritize native support). For this reason we have published AWSQS::EKS::Cluster. Instructions on activation and usage can be found here.
• Manually: to allow this resource type to access the kubernetes API, follow the instructions in the EKS documentation adding the IAM execution role created above to the system:masters group. (Note: you can scope this down if you plan to use the resource type to only perform specific operations on the kubernetes cluster)

To activate the resource type in your account go here, then choose the AWS Region you would like to use it in and click Activate.

Properties and return values are documented here.
