Ingress with Contour | Open Service Mesh You switched accounts on another tab or window. To be able to discover the endpoints of osm-contour-envoy service, we need OSM controller to monitor the corresponding namespace. After the final GOAWAY frame has been sent, the proxy will refuse new streams. Sign in Have a question about this project? Will this include the ability to specify a CA bundle for the upstream service? Already on GitHub? This parameter should only be used by advanced users. This article shows how to add multiple VSEs, Coordinators, or Simulators in Devtest Setup using Contour Ingress Controller. EDIT: Fixed, it's supposed to be protocol: tls not protocol: https. This field specifies the default request timeout. the configuration file to match the environment in which Envoy is deployed. Address to connect to Contour xDS server on. Defines what DNS Resolution Policy to use for Envoy -> Contour cluster name lookup. Contour version: latest Kubernetes version: (use kubectl version ): Client Version: v1.18.3 Server Version: v1.18.3 Kubernetes installer & version: Cloud provider or hardware configuration: On Prem OS (e.g. Acts as a container for a set of rate limit definitions within the RLS. 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. # Configure the port used to access the Envoy Admin interface. to your account. 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. This field defines whether to translate status code 429 to gRPC RESOURCE_EXHAUSTED instead of UNAVAILABLE. Documentation - projectcontour.io Contour Configuration File. nginx-ingress has this today via an annotation, I'm also curious if this might be supported as a first-rate field in the new CRDs instead of just via annotations? The TLS configuration block can be used to configure default values for how The default request headers set or removed on all service routes if not overridden in the object, The default response headers set or removed on all service routes if not overridden in the object, Whether the global policy should apply to Ingress objects, Map of headers to set on all service routes if not overridden in the object, List of headers to remove on all service routes if not overridden in the object, This field identifies the extension service defining the rate limit service, formatted as. This field defines whether to include the X-RateLimit headers X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset (as defined by the IETF Internet-Draft. This sets the service name that will be inspected for address details to be applied to Ingress objects. This helps prevent the case of proxying to an upstream where validation is requested, but not yet available. projectcontour.io/tls-minimum-protocol-version : The minimum TLS protocol version the TLS listener should support. There are flags that can be passed to contour bootstrap that help configure how Envoy see annotations section). The duration leader will retry refreshing leadership before giving up. A configuration file can be passed to the --config-path argument of the contour serve command to specify additional configuration to Contour. # ref. To see all available qualifiers, see our documentation. This field specifies the name of the Kubernetes secret to use as the fallback certificate. You signed in with another tab or window. Lets update the principal to something other than the SAN encoded in the ingress gateways certificate. Note: https://projectcontour.io/docs/v1.13.1/config/external-service-routing/#external-service-routing, Contour version: tested with 1.12 and 1.13.1, Cloud provider or hardware configuration: aws (eks). Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Yes, you can close this ticket since we are planing a migration to Contour 1.0.0. Sign in Only one of. You can rewrite this with the headers policy bit. @stevesloka @mattmoor is it possible to extend the validation on this field with some kind of enumeration; ie, one of "", "tls", "whatever". If both the annotation and the protocol field are specified, the protocol field takes precedence. to your account, I'm trying to expose a grpc port using ingress contour the grpc app it has tls enabled and it uses ca to validate the access Refer to the Upstream TLS section to learn more about upstream certificate validation and when certificate delegation is necessary. I'm wondering if the newer certificate is using some newer ciphersuite that doesn't match up with something. (Despite the annotation sole purpose is for configuring Contour ingress!). You switched accounts on another tab or window. If set, Contour will reconcile the oldest GatewayClass, and its oldest Gateway, with this controller string. The set of ciphers that are allowed is a superset of those supported by default in stock, non-FIPS Envoy builds and FIPS builds as specified here . If spec.routes.services[].validation is present, spec.routes.services[]. . Adopt port-name heuristic for protocol selection. I've been using the following manifest: However most recently I've tried this with a new service with no luck. Options are, Gateway Class controller name (i.e. The text was updated successfully, but these errors were encountered: Sorry about taking a while to get back to you @juanvasquezreyes. 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. Well occasionally send you account related emails. You must also add an OSM provides the option to use Contour ingress controller and Envoy based edge proxy to route external traffic to service mesh backends. In addition to the CA certificate and the subject name, the Kubernetes service must also be annotated with a Contour specific annotation: projectcontour.io/upstream-protocol.tls: <port> ( see annotations section ). The leader election configuration block configures how a deployment with more than one Contour pod elects a leader. ***> wrote: nginx.ingress.kubernetes.io/backend-protocol: HTTPS is the annotation that describes the protocol nginx will use with the upstream Pod; if your upstream isn't listening on port 5422 for TLS traffic, you should remove that annotation (since the default is HTTP) The contour serve command is the main command which is used to watch for Kubernetes resource and process them into Envoy configuration which is then streamed to any Envoy via its xDS gRPC connection. When using L4 (tcpproxy) using . We ask that you enable this before asking for help on the community forums. The text was updated successfully, but these errors were encountered: Is there a (non explicit) way of using an HTTPS upstream service today? or greater. Add upstream support for HTTP/1.1 + TLS annotation to the service This sets the namespace of the service that will be inspected for address details to be applied to Ingress objects. The traffic is routed via HTTPProxy provided by contour v1.17.0. Moving to the backlog for prioritisation, /cc @michmike. If you're watching this issue, this feature is available in the :master image now and can be tested now. Add upstream support for HTTP/1.1 + TLS annotation to the service, https://github.com/notifications/unsubscribe-auth/AAAcA7a7uEbGQrPrio5H82bjsu_qRHjtks5uCquXgaJpZM4UJijJ, Support HTTP2 ingress.kubernetes.io/secure-backends: "true", Contour WebSocket Secure traffic throwing 503 errors via end-to-end TLS over 443, https://github.com/jdelgadillo/contour-sample/blob/master/kubernetes/playapp.yaml, https://contour-test-public.westus2.cloudapp.azure.com/, https://contour-test-public.westus2.cloudapp.azure.com/prefix/, Feature Request: Allow "protocol" Be Defined in route.services.service (Enable Upstream TLS).

HTTPProxy Upstream TLS doc - GitHub Clone via HTTPS Clone with Git or checkout with SVN using the repository's web address. Add Multiple VSEs Using Contour Ingress I receive the following error (in the response): I've tried the new spec.virtualhost.tls.clientValidation.skipClientCertValidation field however all that does is cause the browser to request a client cert and doesn't fix the issue. You switched accounts on another tab or window. In addition to the CA certificate and the subject name, the Kubernetes service must also be annotated with a Contour specific annotation: projectcontour.io/upstream-protocol.tls: ( The name of the ConfigMap that Contour leader election will lease. Minio with custom CA - J's Software Development Pages - GitHub Pages if this might be supported as a first-rate field in the new CRDs instead of So try changing your header key to Host with a capital H and also move the requestHeadersPolicy back a level to the route level not the service level. Awesome! We read every piece of feedback, and take your input very seriously. //ref: https://projectcontour.io/docs/v1.13.1/config/external-service-routing/#external-service-routing. Successfully merging a pull request may close this issue. 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. If present, this specifies custom access log format for Envoy. Something like, Update, I think this annotation should be. The gateway configuration block is used to configure which gateway-api Gateway Contour should configure: The Policy configuration block can be used to configure default policy values # the timeout defined on the extension service. projectcontour.io/gateway-controller). Could you check what ciphers the serving certificate is using? We read every piece of feedback, and take your input very seriously. A HTTPProxy can proxy to an upstream TLS backend by annotating the upstream Kubernetes Service or by specifying the upstream protocol in the HTTPProxy Note that this is a timeout for the entire request, not an idle timeout. Ingress Configuration - Argo CD - Declarative GitOps CD for Kubernetes 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. If not specified, Envoy defaults of 1MiB apply, This field specifies the xDS Server to use. Timeout will not trigger while HTTP/1.1 connection is idle between two consecutive requests. Either v4, v6, auto or all. I'm trying to proxy to an external service using contour. On 25 Jan 2020, at 07:38, Steve Sloka wrote: On 3 July 2018 at 09:24, Cole Mickens ***@***. The certificate was issued by cert-manager.io v1.4.0 with this configuration (snippet): 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. 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. This field specifies that Contour is running in a Kubernetes cluster and should use the in-cluster client access configuration. 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. I've checked and there is no upstream request leaving the envoy towards the backend server in this scenario. Ingress: Secure GRPC Backend Issue #3470 projectcontour/contour Defines the maximum heap size in bytes until Envoy overload manager stops accepting new connections. Port the metrics HTTP endpoint will bind to. Excuse me, I am having trouble using the new protocol: https feature. when I disable tls and use h2c works fine, but when I tried to expose it through httpproxy it doesnt work as expected using h2, At the service I added the annotation Non-essential for closing out remaining IngressRoute work. EC2 ELB PROXY protocol support for special instructions. Values: If this field is true, Contour will ignore. The same configuration can be specified by setting the protocol name in the spec.routes.services [].protocol field on the HTTPProxy object. Documentation - projectcontour.io Two configuration items are required, a CA certificate and a SubjectName which are both used to verify the backend endpoints identity. Here is the ^ the example in the release note is supposed to be protocol: tls not protocol: https!!! These are. When defining upstream services on a route, its possible to configure the connection from Envoy to the backend endpoint to communicate over TLS. You signed in with another tab or window. I have this working in a small PoC, happy to take this on if the approach seems reasonable. A common way to implement this is to use TLS support - Contour https://contour-test-public.westus2.cloudapp.azure.com/prefix/. It is possible that this combination of features was broken in 0.15.3, but as that release is superseded by 1.0.0 there is probably no action to be taken. This array specifies the HTTP versions that Contour should program Envoy to serve. 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). Contour also introduces a new ingress API ( HTTPProxy) which is implemented via a Custom Resource Definition (CRD). 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.
