Specifically, the name must be 1-63 characters long and match the regular expression [aZ]([AZ09]*[aZ09])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

  • defaultService - (Optional) The backend service or backend bucket to use when none of the given rules match.

  • description - (Optional) An optional description of this resource. Provide this property when you create the resource.

  • headerAction - (Optional) Specifies changes to request and response headers that need to take effect for the selected backendService. The headerAction specified here take effect after headerAction specified under pathMatcher. Structure is documented below.

  • hostRule - (Optional) The list of HostRules to use against the URL. Structure is documented below.

  • pathMatcher - (Optional) The list of named PathMatchers to use against the URL. Structure is documented below.

The order by which path rules are specified does not matter. Matches are always done on the longest-path-first basis. For example: a pathRule with a path /a/b/c/* will match before /a/b/* irrespective of the order in which those paths appear in this list. Within a given pathMatcher, only one of pathRules or routeRules must be set. Structure is documented below.

  • routeRules - (Optional) The list of ordered HTTP route rules. Use this list instead of pathRules when advanced route matching and routing actions are desired. The order of specifying routeRules matters: the first rule that matches will cause its specified routing action to take effect. Within a given pathMatcher, only one of pathRules or routeRules must be set. routeRules are not supported in UrlMaps intended for External load balancers. Structure is documented below.

If all traffic needs to go to a single backend service, there must be one weightedBackendService with weight set to a non 0 number. Once a backendService is identified and before forwarding the request to the backend service, advanced routing actions like Url rewrites and header transformations are applied depending on additional settings specified in this HttpRouteAction. Structure is documented below.

The defaultRouteAction block supports:

  • weightedBackendServices - (Optional) A list of weighted backend services to send traffic to when a route match occurs. The weights determine the fraction of traffic that flows to their corresponding backend service. If all traffic needs to go to a single backend service, there must be one weightedBackendService with weight set to a non 0 number. Once a backendService is identified and before forwarding the request to the backend service, advanced routing actions like Url rewrites and header transformations are applied depending on additional settings specified in this HttpRouteAction. Structure is documented below.

  • urlRewrite - (Optional) The spec to modify the URL of the request, prior to forwarding the request to the matched service. Structure is documented below.

  • timeout - (Optional) Specifies the timeout for the selected route. Timeout is computed from the time the request has been fully processed (i.e. end-of-stream) up until the response has been completely processed. Timeout includes all retries. If not specified, will use the largest timeout among all backend services associated with the route. Structure is documented below.

  • retryPolicy - (Optional) Specifies the retry policy associated with this route. Structure is documented below.

  • requestMirrorPolicy - (Optional) Specifies the policy on how requests intended for the route's backends are shadowed to a separate mirrored backend service. Loadbalancer does not wait for responses from the shadow service. Prior to sending traffic to the shadow service, the host / authority header is suffixed with -shadow. Structure is documented below.

  • corsPolicy - (Optional) The specification for allowing client side cross-origin requests. Please see W3C Recommendation for Cross Origin Resource Sharing Structure is documented below.

  • faultInjectionPolicy - (Optional) The specification for fault injection introduced into traffic to test the resiliency of clients to backend service failure. As part of fault injection, when clients send requests to a backend service, delays can be introduced by Loadbalancer on a percentage of requests before sending those request to the backend service. Similarly requests from clients can be aborted by the Loadbalancer for a percentage of requests. timeout and retryPolicy will be ignored by clients that are configured with a faultInjectionPolicy. Structure is documented below.

The weightedBackendServices block supports:

  • backendService - (Optional) The full or partial URL to the default BackendService resource. Before forwarding the request to backendService, the loadbalancer applies any relevant headerActions specified as part of this backendServiceWeight.

  • weight - (Optional) Specifies the fraction of traffic sent to backendService, computed as weight / (sum of all weightedBackendService weights in routeAction) . The selection of a backend service is determined only for new traffic. Once a user's request has been directed to a backendService, subsequent requests will be sent to the same backendService as determined by the BackendService's session affinity policy. The value must be between 0 and 1000

The urlRewrite block supports:

  • pathPrefixRewrite - (Optional) Prior to forwarding the request to the selected backend service, the matching portion of the request's path is replaced by pathPrefixRewrite. The value must be between 1 and 1024 characters.

  • hostRewrite - (Optional) Prior to forwarding the request to the selected service, the request's host header is replaced with contents of hostRewrite. The value must be between 1 and 255 characters.

    • connect-failure: Loadbalancer will retry on failures connecting to backend services, for example due to connection timeouts.
    • retriable-4xx: Loadbalancer will retry for retriable 4xx response codes. Currently the only retriable error supported is 409.
    • refused-stream:Loadbalancer will retry if the backend service resets the stream with a REFUSED_STREAM error code. This reset type indicates that it is safe to retry.
