I've never seen anyone do that before, so I'm wondering if there's some weird interaction there? privacy statement. Namespace is used as part of the metric names on static resources defined in the bootstrap configuration file. I'm sorry that I can't offer more concrete advice, we haven't seen much like this before. Optional path to the CA certificate file used to verify client certificates. There's probably a lot of infrastructure we can leverage, https://github.com/heptio/contour/blob/master/internal/dag/builder.go#L258, Sets the Protocol field on dag.HTTPService, which is read here, https://github.com/heptio/contour/blob/master/internal/envoy/cluster.go#L47. Taking a look at issues I've seen in other repos, it looks like this BAD_ECC_CERT error is caused by something about the certificate itself being off. Port to connect to Contour xDS server on. All rights reserved. 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've checked and there is no upstream request leaving the envoy towards the backend server in this scenario. Have a question about this project? 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. Note: # Identifies the extension service defining the rate limit service, # extensionService: projectcontour/ratelimit. As an example, I've got this application (http1.1 only) https://github.com/jdelgadillo/contour-sample/blob/master/kubernetes/playapp.yaml deployed here for WebSockets wss://contour-test-public.westus2.cloudapp.azure.com/ws and Http/html https://contour-test-public.westus2.cloudapp.azure.com/.

Already on GitHub? 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. A configuration file can be passed to the --config-path argument of the contour serve command to specify additional configuration to Contour. # The default access log format is defined by Envoy but it can be customized by setting following variable. 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 ). 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 The next section outlines all the available flags that can be passed to the contour bootstrap command which are used to customize By clicking Sign up for GitHub, you agree to our terms of service and This field specifies the default request timeout. Is that something that kubebuilder can do? Configures the number of additional ingress proxy hops from the right side of the x-forwarded-for HTTP header to trust. The server configuration block can be used to configure various settings for the contour serve command. 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. 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. Well occasionally send you account related emails. projectcontour.io/gateway-controller). If present, this specifies custom access log format for Envoy. This configuration file configures the Envoy container to connect to Contour and receive configuration via xDS. You signed in with another tab or window. Could you check what ciphers the serving certificate is using? If the. file for easy deployment of Contour. Many of these flags are mirrored in the or ingressroute document. Contour supports dynamic configuration updates out of the box while maintaining a lightweight profile. Certificates must be provisioned which are saved as Kubernetes secrets and get passed to Envoy. This field defines whether to translate status code 429 to gRPC RESOURCE_EXHAUSTED instead of UNAVAILABLE. Only one of. Please tell us how we can improve. is there an annotation missing? 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). We read every piece of feedback, and take your input very seriously. Ill investigate today. This is the configuration of coredns rewrite, envoy egress and the external service as an externalname. This is Envoys default setting value and is not explicitly configured by Contour. Metrics and health endpoints cannot have the same port number when metrics are served over HTTPS. We need a couple of things to make this work: Ensure that you have the http.proto and annotations.proto copied in your project's proto folder under a sub-directory ./ google/api . The only working solution is to reduce key size from 384 to 256. The referenced Secret must be of type Opaque and have a data key named ca.crt. Port the metrics HTTP endpoint will bind to. Open Service Mesh Authors 2022 | Documentation Distributed under CC-BY-4.0. 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). EC2 ELB PROXY protocol support for special instructions. Contour is an Ingress controller for Kubernetes that works by deploying the Envoy proxy as a reverse proxy and load balancer. In its absence, Contour will operate with reasonable defaults. # Replace osm-system with the namespace where OSM will be installed, # Replace osm with the desired OSM mesh name, apiVersion: policy.openservicemesh.io/v1alpha1, number: 14001 # targetPort of httpbin service, # subjectName for a service is of the form ..cluster.local, # where the service account and namespace is that of the pod backing the service, subjectName: httpbin.httpbin.cluster.local, skipClientCertValidation: false # mTLS (defaults to false), name: "osm-contour-envoy.$osm_namespace.cluster.local", Ingress with Kubernetes Nginx Ingress Controller, Egress Passthrough to Unknown Destinations, Integrate OSM with Prometheus and Grafana. 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. Values are: This field specifies the maximum requests for upstream connections. to your account. You must also add an Thank you. The length of time that the leader will retry refreshing leadership before giving up. CA filename for Envoy secure xDS gRPC communication. If not specified, Envoy defaults of 1MiB apply. This is the list the field names to include in the JSON, Enable ExternalName Service processing. If you deploy behind an AWS Elastic Load Balancer, see Note that this is ignored when TLS 1.3 is in use. From the look of the error message, it seems like OpenSSL is rejecting a certificate for some reason. View the docs for the latest release here. Client key filename for Envoy secure xDS gRPC communication. The TLS configuration block can be used to configure default values for how We read every piece of feedback, and take your input very seriously. Defines the maximum heap size in bytes until Envoy overload manager stops accepting new connections. Refer to the Upstream TLS section to learn more about upstream certificate validation and when certificate delegation is necessary. 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 The same configuration can be specified by setting the protocol name in the spec.routes.services [].protocol field on the HTTPProxy object. Note: the values of entries in the set and remove fields can be overridden in HTTPProxy objects but it it not possible to remove these entries. @stevesloka @mattmoor is it possible to extend the validation on this field with some kind of enumeration; ie, one of "", "tls", "whatever". Timeout will not trigger while HTTP/1.1 connection is idle between two consecutive requests. eg. It seems like the TLS annotation is ignored and Envoy doesn't consider the upstream service over tls. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. You are viewing docs for the v1.0 release. 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 request-headers field is used to rewrite headers on a HTTP request, and Seems like maybe test.com might not match?
