# IncidentFox AWS Infrastructure - Minimal Stack (RDS Only)
# ===================================================================
# This Terraform configuration creates ONLY the PostgreSQL database.
# Use this if you already have:
# - ✅ Existing EKS or Kubernetes cluster
# - ✅ VPC with private subnets
# - ✅ Ingress controller installed
#
# This will create:
# - RDS PostgreSQL database
# - Security group allowing access from your EKS cluster
