# hello-world — Gateway API + cert-manager + external-dns end-to-end test
#
# Tests:
#   - Cilium Gateway provisioning (10.1.71.90 from cilium-gateway pool)
#   - cert-manager DNS-01 cert issuance (letsencrypt-staging)
#   - external-dns A record creation in Technitium via RFC2136
#   - HTTPRoute routing to backend service
#
# Cleanup when done:
#   kubectl delete -f hello-world.yaml -n default
# ------------------------------------------------------------------------------
