Provisions the AWS infrastructure required by the gharts service on the arc dev cluster.

  • RDS db.t3.micro PostgreSQL instance with IAM authentication enabled
  • Security group allowing PostgreSQL access from within the VPC
  • DB subnet group covering private subnets
  • IAM role and rds-db:connect policy for IRSA
  • Outputs: gharts_rds_host, gharts_irsa_role_arn (consumed by 02_helm)
