📄 Description

Add support for Kubernetes Gateway API (HTTPRoute) and Istio (VirtualService) as ingress alternatives alongside the existing Ingress resource. Only one mode can be enabled at a time, enforced by a mutual exclusivity validation.

  • Add gateway and istioGateway sections to values.yaml
  • Add http_route.yaml template with basePath + URLRewrite support
  • Add virtual_service.yaml template with basePath rewrite (exact + prefix rules)
  • Service templates force ClusterIP and drop HTTPS port when mesh ingress is active
  • Add validation for required fields (gateway.name, istioGateway.name, ingress.hostname)
  • Guard ingressClassName and loadBalancerIP against empty values
  • Normalize basePath with trimPrefix/trimSuffix to handle leading/trailing slashes
  • Match langsmith chart conventions (file naming, namespace formatting)
