# Gateway Service Installation Template
# This file provides common targets for deploying Gateway API based services.
# It extends crd.mk with Gateway-specific verification and utilities.
#
# Usage:
#   include ../_template/crd.mk
#   include ../_template/gateway.mk
#
# Required variables (inherited from crd.mk):
#   HELM_RELEASE_NAME        - The name of the Helm release
#   HELM_NAMESPACE           - The namespace for the deployment
#   HELM_CHART_VERSION       - The version of the Helm chart
#
# Additional required variables:
#   GATEWAY_CLASS_NAME       - The name of the GatewayClass (e.g., "kgateway", "agentgateway")
#   CRD_HELM_CHART_REPO      - The Helm chart repository for CRDs
#
# Optional variables:
#   GATEWAY_API_VERSION      - Version of Gateway API (defaults to v1.4.0)
#   ENABLE_GATEWAY_VERIFY    - Set to "true" to enable gateway verification (defaults to true)
