Gloo is an API Gateway built on Envoy Proxy that highly complements a service mesh like Istio with edge capabilities like transformations, OIDC authentication, OPA authorization, Web Application Firewalling (WAF), and others. This can be integrated with Istio gateways to manage TLS certificates. cert-manager can be used to obtain certificates by using signature key pairs stored. Update the ingress gateway to set externalTrafficPolicy: local to preserve the original client source IP on the ingress gateway using the following command: $ kubectl patch svc istio-ingressgateway -n istio-system -p '{"spec":{"externalTrafficPolicy":"Local"}}' Verify that the httpbin workload and ingress gateway are working. A possible approach is to use a direct client-to-microservice communication architecture. The Envoy proxy gets its traffic management rules from Pilot. GitHub Gist: instantly share code, notes, and snippets. Istio has replaced the familiar Ingress resource with new Gateway and VirtualServices resources. Destination Rules. At Aspen Mesh we love gRPC. Usage Istio Gateway. Istio consists of a control plane and sidecars that are injected into application pods. The bookinfo-gateway object is configured to listen to all HTTP traffic, but gateways can be restricted to specific ports and host names; The destination is the actual target where traffic will be routed (which can be different from the requested domain name). We'll do that with a VirtualService. You can use an alternative port if that is what you have opened in your Istio ingress gateway, but you will then need to make sure that your Defender DaemonSet reflects the updated port. Implement all the DataPower gateway functionality and also implement the policies on the Istio mesh, but then the entire mesh can be secured using DataPower issued JWT tokens.
