Struct GrpcRouteSpec

pub struct GrpcRouteSpec {
    pub inner: CommonRouteSpec,
    pub hostnames: Option<Vec<String>>,
    pub rules: Option<Vec<GrpcRouteRule>>,
}

Spec defines the desired state of GrpcRoute.

Fields

inner: CommonRouteSpec

Common route information.

hostnames: Option<Vec<String>>

Hostnames defines a set of hostnames to match against the GRPC Host header to select a GRPCRoute to process the request. This matches the RFC 1123 definition of a hostname with 2 notable exceptions:

1. IPs are not allowed.
2. A hostname may be prefixed with a wildcard label (*.). The wildcard label MUST appear by itself as the first label.

If a hostname is specified by both the Listener and GRPCRoute, there MUST be at least one intersecting hostname for the GRPCRoute to be attached to the Listener. For example:

• A Listener with test.example.com as the hostname matches GRPCRoutes that have either not specified any hostnames, or have specified at least one of test.example.com or *.example.com.
• A Listener with *.example.com as the hostname matches GRPCRoutes that have either not specified any hostnames or have specified at least one hostname that matches the Listener hostname. For example, test.example.com and *.example.com would both match. On the other hand, example.com and test.example.net would not match.

Hostnames that are prefixed with a wildcard label (*.) are interpreted as a suffix match. That means that a match for *.example.com would match both test.example.com, and foo.test.example.com, but not example.com.

If both the Listener and GRPCRoute have specified hostnames, any GRPCRoute hostnames that do not match the Listener hostname MUST be ignored. For example, if a Listener specified *.example.com, and the GRPCRoute specified test.example.com and test.example.net, test.example.net MUST NOT be considered for a match.

If both the Listener and GRPCRoute have specified hostnames, and none match with the criteria above, then the GRPCRoute MUST NOT be accepted by the implementation. The implementation MUST raise an ‘Accepted’ Condition with a status of False in the corresponding RouteParentStatus.

If a Route (A) of type HTTPRoute or GRPCRoute is attached to a Listener and that listener already has another Route (B) of the other type attached and the intersection of the hostnames of A and B is non-empty, then the implementation MUST accept exactly one of these two routes, determined by the following criteria, in order:

• The oldest Route based on creation timestamp.
• The Route appearing first in alphabetical order by “{namespace}/{name}”.

The rejected Route MUST raise an ‘Accepted’ condition with a status of ‘False’ in the corresponding RouteParentStatus.
