Gateway API

Purpose: For platform engineers, operators, application teams, documents the Envoy Gateway based gateway-api service in openCenter-gitops-base.

The gateway-api service deploys Envoy Gateway as the implementation for Kubernetes Gateway API resources.

What This Repo Deploys

  • Namespace/envoy-gateway-system

  • HelmRelease/envoy-gateway-api

  • Base values Secret: envoy-gateway-api-values-base

  • Optional override Secret: envoy-gateway-api-values-override

When to Use It

  • You want Gateway API rather than legacy ingress-only routing.

  • You need shared edge infrastructure with delegated route ownership.

Key Integration Points

  • cert-manager usually provides TLS automation.

  • MetalLB or a cloud load balancer provides external IPs.

Example

apiVersion: gateway.networking.k8s.io/v1
kind: HTTPRoute
metadata:
  name: app
spec:
  parentRefs:
    - name: public
      namespace: envoy-gateway-system
  rules:
    - backendRefs:
        - name: app
          port: 80

Configuration Surfaces

  • Service path: applications/base/services/gateway-api/

  • Namespace: envoy-gateway-system
