Port 443 is not opened by envoy. {name,port} must point to a Service with a matching projectcontour.io/upstream-protocol.tls Service annotation. Contour can be configured with a namespace/name in the Though, I'm sure it's there. TLS functionality would be nice so you could mix HTTP and HTTPS (passthrough) services in one ingress. Usually, the decryption or SSL termination happens at the load balancer and data is passed along to a web server as plain HTTP. And .. it worked, sort of.. @davecheney Thanks for the detailed explanation! Its important to note that this only provides authentication, not authorization. HTTP: Debug logs from Envoy contain the following. Our latest release, Contour 1.1, now includes request and response header manipulation as well as host rewriting to external domains. This proposal describes the facility for Envoy to verify the backend service's certificate. my question is how I can configure the ingress to receive https requests and to forward those https requests to the https back-end? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The numerical TLs with the eddy are consistent with the experimental TLs, which confirms the influence of the warm eddy and enables the quantitative estimation of the variations. Afaik, HAPROXY is the originator of the protocol. GitHub Notifications Fork 616 3.3k Actions rusenask commented It relies on TLS/SNI for host name routing. The same configuration can be specified by setting the protocol name in the spec.routes.services[].protocol field on the HTTPProxy object. At this point, routing is executed and the data proceeds to the destination server as plain HTTP traffic. Accessing Kafka: Part 5 - Ingress - Strimzi However, QuotaGuard does have to decrypt the data, using your security keys, to determine the next hop and then re-encrypt the data before it is sent to the next point. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Two configuration items are required, a CA certificate and a SubjectName which are both used to verify the backend endpoints identity. This document is an attempt to elaborate step by step to Install Contour on TKGI with. And thats appears to me the exact scenario of TLS passthrough. page. Phldlphzn1, . Please correct me if any. Respectfully, notice the difference with proxy protocol on, and off: #793 (comment). Curl returns SSL_ERROR_SYSCALL or Server aborted the SSL handshake depending on the version.

You should see output like ["0.0.0.0:8002","0.0.0.0:8080","0.0.0.0:8443"] if you have configured TLS correctly for Contour. If Envoy is not listening on port 8443, check your Secret and Ingress configuration. without performing TLS handshake at the proxy), and simply forwarding encrypted TCP packets between TLS endpoints, in both: Envoy (using TLS Inspector) and NGINX (using ngx_stream_ssl_preread_module). 594), Stack Overflow at WeAreDevelopers World Congress in Berlin, Temporary policy: Generative AI (e.g., ChatGPT) is banned, Preview of Search and Question-Asking Powered by GenAI, Kubernetes internal nginx ingress controller with SSL termination & ssl-passthrough. Is it the service the ingress points to? NGINX ingress controller has this ingress.kubernetes.io/ssl-passthrough: "true" annotation, it might make sense to keep the format the same to make it easier to switch between ingresses. On the other hand, if people cannot touch the payload, while still want to route traffic to specific target using shared IP/port, here comes the SNI. As it seems to be declared as out-of-scope in #787, when do you think would be the best release/time window to implement this? To see all available qualifiers, see our documentation. Certificates must be provisioned which are saved as Kubernetes secrets and get passed to Envoy. The change was adding the parameter to spec.containers.args: Then I've added the following annotations to my ingress: The important one are secure-backends and ssl-passthrough but I think the rest are a good idea, provided you're not expecting http traffic there, SSH-Passthrough is working fine for me. ingress.kubernetes.io/secure-backend: "false/true". You never have to share your private keys with a third party, like QuotaGuard. see annotations section). What steps did you take and what happened: Following tutorial, deployed Contour as DaemonSet on VM-based cluster. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. How common is it for US universities to ask a postdoc to bring their own laptop computer etc.? TLS backend verification. Some thought about how to change the routes section of the spect will probably be needed. @256dpi sorry it's taken me so long to get back to this issue, this is something i'm hoping to address in beta.1 (or at least confirm that we cannot support it for Contour 1.0). 1 Answer Sorted by: 1 You cannot pass through the IP address when you are passing through TLS. If there are no concerns regarding the compromise of data passing from the proxy to the destination server, SSL Termination is likely a better solution. In addition Contour 1.4 upgrades Envoy to 1.14.1, to keep up with Envoys current supported version. external-dns. Well, you can now configure your HTTPProxy routes so that they require a client certificate supplied by your client (usually your browser), which allows you to use that client certificate for authentication. Deployed cert-manager, with Self Signing Issuer, and CA Issuer. This preserves the old behavior so that we dont break you if thats what you expect. Yet, when working around host header with port 9443 caveat by port forwarding 443->9443, curl reports Server aborted the SSL handshake, I'm using a LoadBalancer in L4 mode, configured out-of-band, to proxy from it's VIP to K8s worker nodes, where Contour does what it does (routing, TLS termination, etc). About OKD VirtualizationWhat you can do with OKD VirtualizationOKD Virtualization supported cluster version OKDKubernetesOKDRed Hat OpenShift OnlineRed Hat Open It seems to pick up on, New! How to handle repondents mistakes in skip questions? Already on GitHub? Kubernetes ingress nginx redirect to https, Kubernetes routing HTTPS traffic to external HTTP services. Using TLS with an ingress controller on AKS allows you to secure communication between your applications and experience the benefits of an ingress controller. Hello, it would be good to know whether Contour supports ssl passthrough and if it doesn't - whether it would be possible/reasonable to add it. QuotaGuard Static uses SSL Termination for routing requests between endpoints. Thanks for your reply. Thanks very much to 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. By clicking Sign up for GitHub, you agree to our terms of service and Hot-Reload Certificates and Safely Rollout Envoy with Contour 1.2, Announcing Contour 1.0: A Proxy for Your Multi-Tenant Future, by watching a Service object for the Envoy service, and putting the associated, Operators can also specify an address on Contours command line, using the. Several rays pass through the reciprocal depth, leading to CZ splitting. Cannot explain better than how @PiotrSikora did, thanks! Asking for help, clarification, or responding to other answers. Thanks for the ping. However, the nginx.org/ssl-services will let you pick the services that require TLS on the backend. It is something we would like to add support for but is not urgent enough right now. 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. Enabled proxy-protocol, changed http/https ports to 9080 and 9443 respectively. rev2023.7.27.43548. I included the patch only to show you how its being done. Secure Socket Layer (SSL), more recently known as TLS (Transport Layer Security), is the most common security protocol for HTTP traffic that is traversing on the Internet. Send all traffic on on a specific port to an upstream service. What Happens When I Switch from a Shared to a Dedicated Proxy, How to Change Your QuotaGuard Subscription Plan, How To Provision the QuotaGuard Add-on in Heroku, Check Out QuotaGuard Shield on our Direct Service. I'm open to collaborate on this. There are a number of caveats with this approach: If someone wants to attempt this, I'll mark it for 0.5, but I think the limitations are severe enough that you'd be better off using a service loadbalancer in TCP mode, you're not getting much value by adding Envoy into the mix. But it would not be listening on 443, since I'm looking for Contour Ingress to provide TLS termination. The referenced Secret must be of type Opaque and have a data key named ca.crt. On 14 Nov 2018, at 21:03, Anastas Dancha ***@***. Can we step back and ask what you are trying to accomplish? Also, when the URL of a website address says HTTPS, the S indicates that SSL is being used to secure the connection and encrypt the data. I'm not sure if this is the only problem, but its certainly the first one that will have to be fixed before working on this some more. Use the QuotaGuard wizard to configure your domain name and forwarding URL. Curl may be attempting PROXY V2, I've posted successful examples of using curl --haproxy-protocol. The only downside is that nginx keeps killing long connections. Session affinity based on cookies is not possible since nginx cannot look into the encrypted SSL traffic. So, I do not understand why Kong needs TLS termination in order to support SNI. Documentation - Contour Help Wanted and work with the team on how to resolve them. If you are using the NGINX Ingress controller (https://docs.nginx.com/nginx-ingress-controller/), the nginx.ingress.kubernetes.io/backend-protocol: "HTTPS" does not work. @davecheney, @rosskukulinski can we push this forward knowing that IngressRoute (project) is already more or less well-established? How to Configure Different SSL Termination Types in Openshift - YouTube ***> wrote: 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. If TLS processing is being done by the final k8s service, it feels like you'd want to configure Envoy as a TCP proxy, not a HTTPS proxy. ***> wrote: Certificate management for TLS. The only difference between this and #787 (assuming you're using filter chain matching in Envoy) is whether or not tls_context is included in the config. contour/tls-backend-verification.md at main - GitHub to your account. Our ultimate goal is to look for ways of mixed use for both TLS termination and passthrough. Trouble with HTTPS/TLS termination with use-proxy-protocol #793 Example (https://github.com/nginxinc/kubernetes-ingress/tree/v1.12.0/examples/ssl-services): Thanks for contributing an answer to Stack Overflow! SSL passthrough passes encrypted HTTPS traffic all the way to the backend server without decrypting the traffic on the proxy. Obviously this wouldn't work without the invaluable hint from @PiotrSikora and with your fantastic work on making TCP proxying / forwarding a reality. How to configure nginx ingress in kubernetes for HTTPS backends with custom CA? Does Kong Ingress Controller support TLS passthrough for - Kong Nation ***> wrote: You signed in with another tab or window. Successfully merging a pull request may close this issue. Ingress is an important component of Kubernetes because it cleanly . have you had any luck with using session affinity with cookies for the SSL Passthrough at all? The Ingress YAML should look like this if you want to reach the backend via TLS: The Ingress YAML should look like this if you want to reach the backend via TLS with TLS decryption in the ingress controller: It's important to note that tls-secret is the name of a SecretConfig with a valid Certificate issued for the host (app.myorg.com). They will be decrypted at the Envoy edge and the SNI handshake used to direct the unencrypted traffic to the target pods. Does anyone have an experience with this controller and SSL Passthrough. If I use deprecated IngressRoute CRD - everything fine, I can access to my service both by HTTP and HTTPS (TCPProxy) and my IngressRoute looks like this: but if I'll rewrite IngressRoute to HTTPProxy as a result I had not working TCP proxying. Contour provides virtual host based routing, so that any TLS request is routed to the appropriate service based on both the server name requested by the TLS client and the HOST header in the HTTP request. Pre-requisites Create a private cluster. OverflowAI: Where Community & AI Come Together, Behind the scenes with the folks building OverflowAI (Ep. Controlling Ingress with Contour | VMware Tanzu Developer Center When it can terminate TLS, it can extract HOST from HTTP headers. Making statements based on opinion; back them up with references or personal experience. In the example below, the upstream service is named secure-backend and uses port 8443: If the validation spec is defined on a service, but the secret which it references does not exist, Contour will reject the update and set the status of the HTTPProxy object accordingly. I need you to not set patches but signed PRs. SSL passthrough distributes the decryption load across the backend servers, but every server must have the certificate information. The only thing I can suggest is that Envoy does not use the HA Proxy protocol, so using curl --haproxy-protocol will not work as expected. Have you tried that? The problem is when using tcpproxy you're mixing L4 and L7 in this service. So, Im wondering whats the real difficulties behind for Kong to support this since Kong is built on top of OpenResty, hence based on nginx as well. Does Kong Ingress Controller support TLS passthrough for HTTPs upstream service? This data value must be a PEM-encoded certificate bundle. works. This ticket is a request to add nginx's ssl-passthrough option. I'm sorry I cannot resolve this issue. 2020-11-14 19:01. Contour can route traffic to HTTPS and TLS-enabled TCP services. But when I was trying to curl it, I got some error as below: It looks its because my upstream service was using http as its protocol by default. Im utterly confused what the problem is. Label a contour line beneath a morn of gold. TL;DR Unable to reach Ingress over HTTPS. 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. How client source IP preservation works for loadbalancer services in You can see SSL in action when you look at your website address bar and see the closed lock symbol. Note that this logic change applies to both Ingress and HTTPProxy objects. TCP proxy with TLS passthrough doesn't works on HTTPProxy CRD, internal/dag: Enable TCPProxy with HTTPProxy, Connection closed when connecting to TCP services, Cloud provider or hardware configuration: bare-metal servers vendored by Supermicro. When defining upstream services on a route, its possible to configure the connection from Envoy to the backend endpoint to communicate over TLS. istioglooambasaador contour . This block is used by services which need to know how to reach an Ingress' backing service from outside the cluster, like On 1 Nov 2018, at 23:47, Anastas Dancha ***@***. How NGINX Ingress controller back-end protocol annotation works in path based routing? One caveat is when using an ingress controller with client source IP preservation enabled, TLS pass-through to the destination container will not work. Connect and share knowledge within a single location that is structured and easy to search. . Is it Contour?
