Status is a container for computed information about the HTTPProxy.

When true, this field disables client request authentication for the scope of the policy.

Context is a set of key/value pairs that are sent to the authentication server in the check request. If a context is provided at an enclosing scope, the entries are merged such that the inner scope overrides matching keys from the outer scope.

ExtensionServiceRef specifies the extension resource that will authorize client requests.

AuthPolicy sets a default authorization policy for client requests. This policy will be used unless overridden by individual routes.

ResponseTimeout configures maximum time to wait for a check response from the authorization server. Timeout durations are expressed in the Go Duration format. Valid time units are “ns”, “us” (or “µs”), “ms”, “s”, “m”, “h”. The string “infinity” is also a valid input and specifies no timeout.

If FailOpen is true, the client request is forwarded to the upstream service even if the authorization server fails to respond. This field should not be set in most cases. It is intended for use only while migrating applications from internal authorization to Contour external authorization.

WithRequestBody specifies configuration for sending the client request’s body to authorization server.

MaxRequestBytes sets the maximum size of message body ExtAuthz filter will hold in-memory.

If AllowPartialMessage is true, then Envoy will buffer the body until MaxRequestBytes are reached.

If PackAsBytes is true, the body sent to Authorization Server is in raw bytes.

Specifies whether the resource allows credentials.

AllowOrigin specifies the origins that will be allowed to do CORS requests. Allowed values include “*” which signifies any origin is allowed, an exact origin of the form “scheme://host[:port]” (where port is optional), or a valid regex pattern. Note that regex patterns are validated and a simple “glob” pattern (e.g. *.foo.com) will be rejected or produce unexpected matches when applied as a regex.

AllowMethods specifies the content for the access-control-allow-methods header.

AllowHeaders specifies the content for the access-control-allow-headers header.

ExposeHeaders Specifies the content for the access-control-expose-headers header.

MaxAge indicates for how long the results of a preflight request can be cached. MaxAge durations are expressed in the Go Duration format. Valid time units are “ns”, “us” (or “µs”), “ms”, “s”, “m”, “h”. Only positive values are allowed while 0 disables the cache requiring a preflight OPTIONS check for all cross-origin requests.

AllowPrivateNetwork specifies whether to allow private network requests. See https://developer.chrome.com/blog/private-network-access-preflight.

required, the name of a secret in the current namespace.

(Members of Condition are embedded into this type.)

Errors contains a slice of relevant error subconditions for this object.

Subconditions are expected to appear when relevant (when there is a error), and disappear when not relevant. An empty slice here indicates no errors.

Warnings contains a slice of relevant warning subconditions for this object.

Subconditions are expected to appear when relevant (when there is a warning), and disappear when not relevant. An empty slice here indicates no warnings.

Name of a Kubernetes secret that contains a CA certificate bundle. The secret must contain key named ca.crt. The client certificate must validate against the certificates in the bundle. If specified and SkipClientCertValidation is true, client certificates will be required on requests. The name can be optionally prefixed with namespace “namespace/name”. When cross-namespace reference is used, TLSCertificateDelegation resource must exist in the namespace to grant access to the secret.

SkipClientCertValidation disables downstream client certificate validation. Defaults to false. This field is intended to be used in conjunction with external authorization in order to enable the external authorization server to validate client certificates. When this field is set to true, client certificates are requested but not verified by Envoy. If CACertificate is specified, client certificates are required on requests, but not verified. If external authorization is in use, they are presented to the external authorization server.

ForwardClientCertificate adds the selected data from the passed client TLS certificate to the x-forwarded-client-cert header.

Name of a Kubernetes opaque secret that contains a concatenated list of PEM encoded CRLs. The secret must contain key named crl.pem. This field will be used to verify that a client certificate has not been revoked. CRLs must be available from all CAs, unless crlOnlyVerifyLeafCert is true. Large CRL lists are not supported since individual secrets are limited to 1MiB in size. The name can be optionally prefixed with namespace “namespace/name”. When cross-namespace reference is used, TLSCertificateDelegation resource must exist in the namespace to grant access to the secret.

If this option is set to true, only the certificate at the end of the certificate chain will be subject to validation by CRL.

OptionalClientCertificate when set to true will request a client certificate but allow the connection to continue if the client does not provide one. If a client certificate is sent, it will be verified according to the other properties, which includes disabling validation if SkipClientCertValidation is set. Defaults to false.

API version of the referent. If this field is not specified, the default “projectcontour.io/v1alpha1” will be used

AllowCrossSchemeRedirect Allow internal redirect to follow a target URI with a different scheme than the value of x-forwarded-proto. SafeOnly allows same scheme redirect and safe cross scheme redirect, which means if the downstream scheme is HTTPS, both HTTPS and HTTP redirect targets are allowed, but if the downstream scheme is HTTP, only HTTP redirect targets are allowed.

If DenyRepeatedRouteRedirect is true, rejects redirect targets that are pointing to a route that has been followed by a previous redirect from the current route.

Routes are the ingress routes. If TCPProxy is present, Routes is ignored.

TCPProxy holds TCP proxy information.

Includes allow for specific routing configuration to be included from another HTTPProxy, possibly in another namespace.

LoadBalancer contains the current status of the load balancer.

Conditions contains information about the current status of the HTTPProxy, in an upstream-friendly container.

Contour will update a single condition, Valid, that is in normal-true polarity. That is, when currentStatus is valid, the Valid condition will be status: true, and vice versa.

Contour will leave untouched any other Conditions set in this block, in case some other controller wants to add a Condition.

If you are another controller owner and wish to add a condition, you should namespace your condition with a label, like controller.domain.com/ConditionName.

Scheme is the scheme to be used in the value of the Location header in the response. When empty, the scheme of the request is used.

Hostname is the precise hostname to be used in the value of the Location header in the response. When empty, the hostname of the request is used. No wildcards are allowed.

HeaderName is the name of the HTTP request header that will be used to calculate the hash key. If the header specified is not present on a request, no hash will be produced.

Name is the name of the header to match against. Name is required. Header names are case insensitive.

Present specifies that condition is true when the named header is present, regardless of its value. Note that setting Present to false does not make the condition true if the named header is absent.

NoExact specifies a string that the header value must not be equal to. The condition is true if the header has any other value.

Regex specifies a regular expression pattern that must match the header value.

TreatMissingAsEmpty specifies if the header match rule specified header does not exist, this header value will be treated as empty. Defaults to false. Unlike the underlying Envoy implementation this is only supported for negative matches (e.g. NotContains, NotExact).

Name represents a key of a header

Value represents the value of a header specified by a key

Set specifies a list of HTTP header values that will be set in the HTTP header. If the header does not exist it will be added, otherwise it will be overwritten with the new value.

Namespace of the HTTPProxy to include. Defaults to the current namespace if not supplied.

Conditions are a set of rules that are applied to included HTTPProxies. In effect, they are added onto the Conditions of included HTTPProxy Route structs. When applied, they are merged using AND, with one exception: There can be only one Prefix MatchCondition per Conditions slice. More than one Prefix, or contradictory Conditions, will make the include invalid. Exact and Regex match conditions are not allowed on includes.

Present specifies that condition is true when the named query parameter is present, regardless of its value. Note that setting Present to false does not make the condition true if the named query parameter is absent.

Entries is the list of key-value pair generators.

GenericKey defines a descriptor entry with a static key and value.

RequestHeader defines a descriptor entry that’s populated only if a given header is present on the request. The descriptor key is static, and the descriptor value is equal to the value of the header.

If “v6” is configured, the DNS resolver will only perform a lookup for addresses in the IPv6 family. If “all” is configured, the DNS resolver will perform a lookup for addresses in both the IPv4 and IPv6 family. If “auto” is configured, the DNS resolver will first perform a lookup for addresses in the IPv6 family and fallback to a lookup for addresses in the IPv4 family. If not specified, the Contour-wide setting defined in the config file or ContourConfiguration applies (defaults to “auto”).

Prefix specifies the URL path prefix to be replaced.

If Prefix is specified, it must exactly match the MatchCondition prefix that is rendered by the chain of including HTTPProxies and only that path prefix will be replaced by Replacement. This allows HTTPProxies that are included through multiple roots to only replace specific path prefixes, leaving others unmodified.

If Prefix is not specified, all routing prefixes rendered by the include chain will be replaced.

Replacement is the string that the routing path prefix will be replaced with. This must not be empty.

Terminal is a flag that allows for short-circuiting computing of a hash for a given request. If set to true, and the request attribute specified in the attribute hash options is present, no further hash policies will be used to calculate a hash for the request.

*NOTE: Pay attention to the potential security implications of using this option. Provided header must come from trusted source.

**NOTE: The header rewrite is only done while forwarding and has no bearing on the routing decision.

The policy for managing response headers during proxying. Rewriting the ‘Host’ header is not supported.

The policies for rewriting Set-Cookie header attributes. Note that rewritten cookie names must be unique in this list. Order rewrite policies are specified in does not matter.

If Mirror is true the Service will receive a read only mirror of the traffic for this route. If Mirror is true, then fractional mirroring can be enabled by optionally setting the Weight field. Legal values for Weight are 1-100. Omitting the Weight field will result in 100% mirroring. NOTE: Setting Weight explicitly to 0 will unexpectedly result in 100% traffic mirroring. This occurs since we cannot distinguish omitted fields from those explicitly set to their default values

The speed of traffic increase over the slow start window. Defaults to 1.0, so that endpoint would get linearly increasing amount of traffic. When increasing the value for this parameter, the speed of traffic ramp-up increases non-linearly. The value of aggression parameter should be greater than 0.0.

More info: https://www.envoyproxy.io/docs/envoy/latest/intro/arch_overview/upstream/load_balancing/slow_start

This setting:

1. Enables TLS client certificate validation.
2. Specifies how the client certificate will be validated (i.e. validation required or skipped).

Note: Setting client certificate validation to be skipped should be only used in conjunction with an external authorization server that performs client validation as Contour will ensure client certificates are passed along.

EnableFallbackCertificate defines if the vhost should allow a default certificate to be applied which handles all requests which don’t match the SNI defined in this vhost.

Conditions contains information about the current status of the HTTPProxy, in an upstream-friendly container.

Contour will leave untouched any other Conditions set in this block, in case some other controller wants to add a Condition.

If you are another controller owner and wish to add a condition, you should namespace your condition with a label, like controller.domain.com\ConditionName.

Timeout for receiving a response from the server after processing a request from client. If not supplied, Envoy’s default value of 15s applies.

Timeout for how long the proxy should wait while there is no activity during single request/response (for HTTP/1.1) or stream (for HTTP/2). Timeout will not trigger while HTTP/1.1 connection is idle between two consecutive requests. If not specified, there is no per-route idle timeout, though a connection manager-wide stream_idle_timeout default of 5m still applies.

List of keys, of which at least one is expected to be present in the ‘subjectAltName of the presented certificate.

The fully qualified domain name of the root of the ingress tree all leaves of the DAG rooted at this object relate to the fqdn.

If present the fields describes TLS properties of the virtual host. The SNI names that will be matched on are described in fqdn, the tls.secretName secret must contain a certificate that itself contains a name that matches the FQDN.

This field configures an extension service to perform authorization for this virtual host. Authorization can only be configured on virtual hosts that have TLS enabled. If the TLS configuration requires client certificate validation, the client certificate is always included in the authentication check request.

Specifies the cross-origin policy to apply to the VirtualHost.

The policy for rate limiting on the virtual host.

Providers to use for verifying JSON Web Tokens (JWTs) on the virtual host.
