# modules/ingress: variables
#
# Installs the AWS Load Balancer Controller into the EKS cluster via
# helm_release. The controller watches for Kubernetes Ingress resources
# with `ingressClassName: alb` and provisions AWS ALBs / NLBs for them.
#
# The IRSA role for the controller is created by modules/iam/ (the
# alb_controller submodule-backed role). This module receives the role ARN
# and annotates the controller's service account.
