Ingress Gateway

IngressGateway configures a workload to act as a gateway for traffic entering the mesh. The ingress gateway also provides basic API gateway functionalities such as JWT token validation and request authorization. Gateways in privileged workspaces can route to services outside the workspace while those in unprivileged workspaces can only route to services inside the workspace.

The following example declares an ingress gateway running on pods with app: gateway labels in the ns1 namespace. The gateway exposes a host bookinfo.com on https port 9443 and http port 9090. The port 9090 is configured to receive plaintext traffic and send a redirect to the https port 9443 (site-wide HTTP -> HTTPS redirection). At port 9443, TLS is terminated using the certificates in the Kubernetes secret bookinfo-certs. Clients are authenticated using JWT tokens, whose keys are obtained from the OIDC provider www.googleapis.com. The request is then authorized by an the user's authorization engine hosted at https://company.com/authz before being forwarded to the productpage service in the backend.

If the productpage.ns1 service on Kubernetes has a ServiceRoute with multiple subsets and weights, the traffic will be split across the subsets accordingly.

The following example illustrates defining non-HTTP servers (based on TCP) with TLS termination. Here, kafka.myorg.internal uses non-HTTP protocol and listens on port 9000. The clients have to connect with TLS with the SNI kafka.myorg.internal. The TLS is terminated at the gateway and the traffic is routed to kafka.infra.svc.cluster.local:8000.

If subsets are defined in the ServiceRoute referencing kafka.infra.svc.cluster.local service, then it is also considered while routing.
