# ClickStack with AWS ALB Ingress
#
# This example deploys ClickStack with an AWS Application Load Balancer
# instead of the chart's built-in nginx Ingress. It uses additionalManifests
# to define a fully custom Ingress resource with ALB-specific annotations.
#
# Prerequisites:
#   - AWS Load Balancer Controller installed in the cluster
#     https://kubernetes-sigs.github.io/aws-load-balancer-controller/
#   - ACM certificate provisioned for your domain
#   - Subnets tagged for ALB auto-discovery (or specify them explicitly)
#
# Usage:
#   helm install my-clickstack clickstack/clickstack -f values.yaml
#   # From repo root:
#   # helm install my-clickstack clickstack/clickstack -f examples/alb-ingress/values.yaml
#
# Customize the values below for your environment:
#   - Replace certificate-arn with your ACM certificate ARN
#   - Replace clickstack.example.com with your domain
#   - Adjust ALB annotations as needed (scheme, target-type, etc.)
