gateway.v1alpha2.grpcRoute

"GRPCRoute provides a way to route gRPC requests. This includes the capability to match requests by hostname, gRPC service, gRPC method, or HTTP/2 header. Filters can be used to specify additional processing steps. Backends specify where matching requests will be routed. \n GRPCRoute falls under extended support within the Gateway API. Within the following specification, the word \"MUST\" indicates that an implementation supporting GRPCRoute must conform to the indicated requirement, but an implementation not supporting this route type need not follow the requirement unless explicitly indicated. \n Implementations supporting GRPCRoute with the HTTPS ProtocolType MUST accept HTTP/2 connections without an initial upgrade from HTTP/1.1, i.e. via ALPN. If the implementation does not support this, then it MUST set the \"Accepted\" condition to \"False\" for the affected listener with a reason of \"UnsupportedProtocol\". Implementations MAY also accept HTTP/2 connections with an upgrade from HTTP/1. \n Implementations supporting GRPCRoute with the HTTP ProtocolType MUST support HTTP/2 over cleartext TCP (h2c, https://www.rfc-editor.org/rfc/rfc7540#section-3.1) without an initial upgrade from HTTP/1.1, i.e. with prior knowledge (https://www.rfc-editor.org/rfc/rfc7540#section-3.4). If the implementation does not support this, then it MUST set the \"Accepted\" condition to \"False\" for the affected listener with a reason of \"UnsupportedProtocol\". Implementations MAY also accept HTTP/2 connections with an upgrade from HTTP/1, i.e. without prior knowledge. \n Support: Extended"

Each match is independent, i.e. this rule will be matched if any one of the matches is satisfied. \n For example, take the following matches configuration: \n matches: - method: service: foo.bar headers: values: version: 2 - method: service: foo.bar.v2 \n For a request to match against this rule, it MUST satisfy EITHER of the two conditions: \n - service of foo.bar AND contains the header version: 2 - service of foo.bar.v2 \n See the documentation for GRPCRouteMatch on how to specify multiple match conditions to be ANDed together. \n If no matches are specified, the implementation MUST match every gRPC request. \n Proxy or Load Balancer routing configuration generated from GRPCRoutes MUST prioritize rules based on the following criteria, continuing on ties. Merging MUST not be done between GRPCRoutes and HTTPRoutes. Precedence MUST be given to the rule with the largest number of: \n * Characters in a matching non-wildcard hostname. * Characters in a matching hostname. * Characters in a matching service. * Characters in a matching method. * Header matches. \n If ties still exist across multiple Routes, matching precedence MUST be determined in order of the following criteria, continuing on ties: \n * The oldest Route based on creation timestamp. * The Route appearing first in alphabetical order by \"{namespace}/{name}\". \n If ties still exist within the Route that has been given precedence, matching precedence MUST be granted to the first matching rule meeting the above criteria."

fn spec.rules.matches.withHeaders

withHeaders(headers)

"Headers specifies gRPC request header matchers. Multiple match values are ANDed together, meaning, a request MUST match all the specified headers to select the route."

fn spec.rules.matches.withHeadersMixin

withHeadersMixin(headers)

"Headers specifies gRPC request header matchers. Multiple match values are ANDed together, meaning, a request MUST match all the specified headers to select the route."

Note: This function appends passed data to existing values

obj spec.rules.matches.headers

"Headers specifies gRPC request header matchers. Multiple match values are ANDed together, meaning, a request MUST match all the specified headers to select the route."

fn spec.rules.matches.headers.withName

withName(name)

"Name is the name of the gRPC Header to be matched. \n If multiple entries specify equivalent header names, only the first entry with an equivalent name MUST be considered for a match. Subsequent entries with an equivalent header name MUST be ignored. Due to the case-insensitivity of header names, \"foo\" and \"Foo\" are considered equivalent."

fn spec.rules.matches.headers.withType

withType(type)

"Type specifies how to match against the value of the header."

fn spec.rules.matches.headers.withValue

withValue(value)

"Value is the value of the gRPC Header to be matched."

obj spec.rules.matches.method

"Method specifies a gRPC request service/method matcher. If this field is not specified, all services and methods will match."

fn spec.rules.matches.method.withMethod

withMethod(method)

"Value of the method to match against. If left empty or omitted, will match all services. \n At least one of Service and Method MUST be a non-empty string."

fn spec.rules.matches.method.withService

withService(service)

"Value of the service to match against. If left empty or omitted, will match any service. \n At least one of Service and Method MUST be a non-empty string."

fn spec.rules.matches.method.withType

withType(type)

"Type specifies how to match against the service and/or method. Support: Core (Exact with service and method specified) \n Support: Implementation-specific (Exact with method specified but no service specified) \n Support: Implementation-specific (RegularExpression)"
