Description

Amazon EKS adds envelope encryption for secrets with AWS KMS.

You can now use AWS Key Management Service (KMS) keys to provide envelope encryption of Kubernetes secrets stored in Amazon Elastic Kubernetes Service (EKS). Implementing envelope encryption is considered a security best practice for applications that store sensitive data and is part of a defense in depth security strategy.

Affected Resource(s)

• aws_eks_cluster

Potential Terraform Configuration

resource "aws_eks_cluster" "example" {
  # ... other configuration ...

  encryption_config {
    resources = ["secrets"]

    provider {
      key_arn = aws_kms_key.example.arn
    }
  }
}
