I'm using contour to reverse proxy a number of external services such that it handles domain routing and certificate generation. OSM automatically provisioned a client certificate for the osm-contour-envoy ingress gateway with the Subject Alternative Name (SAN) osm-contour-envoy.$osm_namespace.cluster.local during install, so the IngressBackend configuration needs to reference the same SAN for mTLS authentication between the osm-contour-envoy edge and the httpbin backend.

To restrict ingress traffic on backends to authorized clients, we will set up the IngressBackend configuration such that only ingress traffic from the endpoints of the osm-contour-envoy service can route traffic to the service backend. Now, we expect external clients to be able to access the httpbin service for HTTP requests for the Host: header httpbin.org: To proxy connections to TLS backends using HTTPS, the backend service must be annotated with the port as follows: Next, we need to create an HTTPProxy configuration to use TLS proxying to the backend service, and providing a CA certificate to validate the server certificate presented by the backend service. To test this add the following annotation to your service (this is a property of the k8s service, not the ingress/ingressroute record): Where admin and/or 443 are the names or port numbers of the port on your service document that speak TLS.

Open Service Mesh Authors 2022 | Documentation Distributed under CC-BY-4.0. (Despite the annotation sole purpose is for configuring Contour ingress!). For this to work, we need to first delegate to Contour the permission to read OSMs CA certificate secret from the OSMs namespace when referenced in the HTTPProxy configuration in the httpbin namespace. @Frusty not at the moment, but the scaffolding to add it exists now. For the record I agree with @stevesloka that while the service annotation is the correct place for this information (when I added it I argued that the protocol the service speaks is a property of the service, not who is talking too it) but this has serious usability limitations, so I'm open to adding this field on route.services.service. https://contour-test-public.westus2.cloudapp.azure.com/prefix/.

This guide will demonstrate how to configure HTTP and HTTPS ingress to a service part of an OSM managed service mesh. This field specifies that Contour is running in a Kubernetes cluster and should use the in-cluster client access configuration. Have a question about this project? In your setup though, you've got an SSL connection to Contour's Envoy, and then another from Envoy to the ExternalName service (this is why Steve suggested you check the hostname, as not having the backend app's certificate accept vpn.example.com is a common mistake we've seen). I'd like to change the IngressRoute to use port 443 instead of 80 when talking to the backend. By default, the upstream TLS server certificate will not be validated, but validation can be requested by setting the spec.routes.services[].validation field. Either v4, v6, auto or all. The certificate key pair was loaded into application which was built with Go v1.16.6, HTTPS traffic served/handled by Echo v4.4.0.. Sorry to hear that. Confirm the httpbin service and pod is up and running: Next, we will create the HTTPProxy and IngressBackend configurations necessary to allow external clients to access the httpbin service on port 14001 in the httpbin namespace.

When using L7 (routes), serving https requests and upstreaming to an http server it's working fine. To see all available qualifiers, see our documentation. Certificates must be provisioned which are saved as Kubernetes secrets and get passed to Envoy. This is the configuration of coredns rewrite, envoy egress and the external service as an externalname.
