To use this feature, add the new clientValidation field to the tls stanza of your HTTPProxy document: The caSecret field is a reference to a Kubernetes Secret that holds the CA certificate used to validate the client certificate. The transport layer security (TLS) protocol uses certificates to provide security for communication, encryption, authentication, and integrity. TLS Client authentication Therefore, traffic passes through the proxy encrypted and the destination server (web application server, database server, etc.) Istio. K8s services, what envoy calls clusters, are tired implicitly to routes in the ingressroute spec. Integrating Azure Application Gateway, AGIC and Istio Ingress is an important component of Kubernetes because it cleanly . To get SSL Passthrough to work with QuotaGuard Shield, do the following : Note that you do not have to upload your certificates to QuotaGuard when using QuotaGuard Shield. .

Also, could you go to the Envoy admin page on port 9001 and verify the https listener got created? Advanced annotation docs: https://docs.nginx.com/nginx-ingress-controller/configuration/ingress-resources/advanced-configuration-with-annotations/. Thanks for confirming. Will tell you something with our conclusions or problems we encounter on the road. As I understand it this controller cannot do SSL Passthrough (by that I mean pass the client certificate all the way through to the backend service for authentication), so instead I have been passing the clients subject DN through a header.

When it can terminate TLS, it can extract HOST from HTTP headers. ***> wrote: Our latest release of Contour is 1.4, which includes support for Client Certificate authentication in your HTTPProxy objects, and also updates Contours Ingress support to fix some missing or incorrect behaviors. Certificate management for TLS. The same configuration can be specified by setting the protocol name in the spec.routes.services[].protocol field on the HTTPProxy object. SSL Offloading ) decrypts all HTTPS traffic when it reaches the QuotaGuard proxy server. Find centralized, trusted content and collaborate around the technologies you use most. In this example, NGINX will connect to the ssl-svc using TLS; it ignores any self-signed certificates. ***> wrote: Have a question about this project? Contour can be configured with a namespace/name in the Contour configuration file of a Kubernetes secret which Envoy uses as a client certificate when upstream TLS is configured for the backend. If your QuotaGuard implementation uses a HTTPS URL for the forwarding URL (as most customers do), then the data between QuotaGuard and the final destination is encrypted as well. However, envoyproxy/envoy#1843, suggests that it is possible to do the SNI handshake, but somehow forward the encrypted traffic to the backend service. How common is it for US universities to ask a postdoc to bring their own laptop computer etc.? It could have different SNI so that can share the same IP and port.

This field has mandatory caSecret and subjectName fields, which specify the trusted root certificates with which to validate the server certificate and the expected server name. Secret Configuration. Thanks for your help! I understand that its useful to test software in a stanging environment before deploying but network forwarding jiggery-pokery is very fragile when tls and port forwarding are mixed together. This helps prevent the case of proxying to an upstream where validation is requested, but not yet available. @davecheney just to let you know that we're going to start testing this is the next days.
