What steps did you take and what happened: On the Upstream TLS section of the httpproxy docs there's a TODO which shouldn't have any blockers now (https://projectcontour.io/docs/1.0/httpproxy): The text was updated successfully, but these errors were encountered: Successfully merging a pull request may close this issue. This httpproxy (tcpproxy/tls passthrough) works: This httpproxy (L7 to https backend) fails saying "upstream connect error or disconnect/reset before headers.

The set field sets an HTTP header value, creating it if it doesnt already exist but not overwriting it if it does. @Frusty not at the moment, but the scaffolding to add it exists now. 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. Envoy will keep the original header. I'm doing that - it's in the config I've posted, problem is that the request never leaves the envoy and thus doesn't have the chance to get dropped due to wrong host header. Sign in contour/site/content/docs/main/config/upstream-tls.md at main - GitHub A configuration file can be passed to the --config-path argument of the contour serve command to specify additional configuration to Contour. Documentation - projectcontour.io Directory where resource files will be written. This field defines whether to allow requests to proceed when the rate limit service fails to respond with a valid rate limit decision within the timeout defined on the extension service. 15 comments Contributor davecheney commented on May 22, 2018 edited added this to the 0.6.0 milestone Feature Request: Allow "protocol" Be Defined in route.services.service (Enable Upstream TLS) just via annotations? When using L7 (routes), serving https requests and upstreaming to an https server I'm getting the following response in the client: Any updates on when this may get implemented? Metrics and health endpoints cannot have the same port number when metrics are served over HTTPS. # "Tranfer-Encoding: chunked" is also set. privacy statement. I test with Contour 1.0.0 and the new annotation projectcontour.io/upstream-protocol.tls and it works. Now, we expect external clients to be able to access the httpbin service for HTTP requests for the Host: header httpbin.org with HTTPS proxying over mTLS between the ingress gateway and service backend: To verify that unauthorized clients are not allowed to access the backend, we can update the sources specified in the IngressBackend configuration. However, Contour must NOT be injected with an Envoy sidecar to function properly. 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. During this grace period, the proxy will continue to respond to new streams. "upstream connect error or disconnect/reset before headers. Consider the use of port name to guide protocol selection. This field defines how long the proxy will wait for the upstream connection to be established. You signed in with another tab or window.

You are viewing docs for the v1.0 release. This sets the namespace of the service that will be inspected for address details to be applied to Ingress objects. This parameter should only be used by advanced users. You switched accounts on another tab or window. Hi @tluzon-digibank, does the same setup work if (for testing purposes, you remove the DNS rewrite from the solution? privacy statement. I'm sorry that I can't offer more concrete advice, we haven't seen much like this before. This field defines the action to be applied to the Server header on the response path. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. We read every piece of feedback, and take your input very seriously. 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.

First, we will install OSM and Contour as in the osm-system namespace and name the mesh name as osm. . projectcontour.io/gateway-controller). Envoy should communicate with the upsteam service over tls when using the TLS annotation to the service. I just verified it works with tls backends with prefixRewrite and WebSockets as well. The text was updated successfully, but these errors were encountered: Note that this is ignored when TLS 1.3 is in use. Feature Request: Allow "protocol" Be Defined in route.services.service (Enable Upstream TLS). Enabling TLS support requires Contour version 0.3 or later. If the value is, This field specifies the maximum requests for downstream connections. I've been using the following manifest: However most recently I've tried this with a new service with no luck. I've checked and there is no upstream request leaving the envoy towards the backend server in this scenario. Currently enabling Upstream TLS requires annotations to be added to the backend Service manifest: This causes some maintainability and usability issues, because the annotation and the Contour ingress object are in two different places. To see all available qualifiers, see our documentation. We read every piece of feedback, and take your input very seriously. The CA certificate bundle for the backend service should be supplied in a Kubernetes Secret. Downward API in the Contour Project Contour GitHub Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile. To see all available qualifiers, see our documentation. (Despite the annotation sole purpose is for configuring Contour ingress!). Contour has a precedence of configuration for contour serve, meaning anything configured in the config file is overridden by environment vars which are overridden by cli flags. 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. contour.heptio.com/upstream-protocol.tls: "https,443", I have a look to the Envoy config_dump and noticed that the "tls context" config is missing in the cluster. Contour is an Ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer. This field defines the rate limit domain value to pass to the rate limit service. What did you expect to happen: This field specifies the default request timeout. I have this working in a small PoC, happy to take this on if the approach seems reasonable. External TLS Upstream Returns - GitHub the configuration file to match the environment in which Envoy is deployed. Something like, Update, I think this annotation should be. Certificates must be provisioned which are saved as Kubernetes secrets and get passed to Envoy. Applying the projectcontour.io/upstream-protocol.tls annotation to a Service object tells Contour that TLS should be enabled and which port should be used for the TLS connection. Backend applications can validate the certificate to ensure that the connection is coming from Envoy. Already on GitHub? Well occasionally send you account related emails. I have a service that can successfully use HTTP2 over HTTPS, but cannot get WebSockets to work via that route. The network configuration block can be used to configure various parameters network connections. Client key filename for Envoy secure xDS gRPC communication. projectcontour.io/v1 kind . Contour also introduces a new ingress API ( HTTPProxy) which is implemented via a Custom Resource Definition (CRD). All fields are optional; Contour/Envoy defaults apply if a field is not specified. Please tell us how we can improve. projectcontour.io/tls-minimum-protocol-version : The minimum TLS protocol version the TLS listener should support. @stevesloka @mattmoor is it possible to extend the validation on this field with some kind of enumeration; ie, one of "", "tls", "whatever". Have a question about this project? We ask that you enable this before asking for help on the community forums. Must be a, This field defines how long the proxy should wait while there is no activity during single request/response (for HTTP/1.1) or stream (for HTTP/2). OSM provides the option to use Contour ingress controller and Envoy based edge proxy to route external traffic to service mesh backends. This guide will demonstrate how to configure HTTP and HTTPS ingress to a service part of an OSM managed service mesh. Configures the number of additional ingress proxy hops from the right side of the x-forwarded-for HTTP header to trust. Once certificate has been replaced, envoy/contour no longer reports what I shared above. TLS Certificate Delegation must be used to allow the owner of the CA certificate secret to delegate, for the purposes of referencing the CA certificate in a different namespace, permission to Contour to read the Secret object from another namespace. Global options (Caddyfile) Caddy Documentation # Defines the rate limit domain to pass to the rate limit service. The bootstrap configuration file is generated by an initContainer in the Envoy daemonset which runs the contour bootstrap command to generate the file.

Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Similarly, for cert with wildcard name *.bar.com, only requests to lower case name will match. Anyhow, due to the fact that the request doesn't leave the envoy I assume that the characteristics of the request are not relevant in this stage, meaning, something that would have been rejected by the external server isn't out yet. 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. I know it's splitting hairs, but I'm sure there will be cases where we have to do TLS between envoy and the backend which don't originate from a browser. Assuming that the hostnames are all good, it may be that you'll need to check the ciphersuites on everything, and check that the ECC variants match on entropy bits (grpc/grpc#6722 mentions P-384 can be a problem and P-256 can work for interacting between OpenSSL and BoringSSL-based implementations, which seems like it would be worth checking).

Certificates must be provisioned which are saved as Kubernetes secrets and get passed to Envoy. Flag can be given multiple times. When defining upstream services on a route, its possible to configure the connection from Envoy to the backend endpoint to communicate over TLS. So in your case for the annotation to work, the projectcontour.io/upstream-protocol.h2: "14250" should be an annotation on the jaeger-collector Service, not the HTTPProxy. However, you've also specified the protocol: h2 field, which would override the annotation anyway, so that's not the source of your problem.
