Component: eks-iam

This component is responsible for provisioning specific IAM roles for Kubernetes Service Accounts. IAM roles are created for the following Kubernetes projects:

  1. aws-load-balancer-controller
  2. cluster-proportional-autoscaler
  3. cert-manager
  4. external-dns

Usage

Stack Level: Regional

Here's an example snippet for how to use this component.

components:
  terraform:
    eks-iam:
      vars:
        standard_service_accounts:
          - "alb-controller",
          - "external-dns"
          - "cert-manager"
