retryConditions
list / elements=string
success
Specfies one or more conditions when this retry rule applies. Valid values are: - 5xx: Loadbalancer will attempt a retry if the backend service responds with any 5xx response code, or if the backend service does not respond at all, example: disconnects, reset, read timeout, connection failure, and refused streams.
- gateway-error: Similar to 5xx, but only applies to response codes 502, 503 or 504.
- 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.
- cancelled: Loadbalancer will retry if the gRPC status code in the response header is set to cancelled - deadline-exceeded: Loadbalancer will retry if the gRPC status code in the response header is set to deadline-exceeded - resource-exhausted: Loadbalancer will retry if the gRPC status code in the response header is set to resource-exhausted - unavailable: Loadbalancer will retry if the gRPC status code in the response header is set to unavailable .

       
timeout

Specifies the timeout for the selected route. Timeout is computed from the time the request is has been fully processed (i.e. end-of-stream) up until the response has been completely processed. Timeout includes all retries. If not specified, the default value is 15 seconds.

         
nanos
integer
success
Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 `seconds` field and a positive `nanos` field. Must be from 0 to 999,999,999 inclusive.

weightedBackendServices
complex
success
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.

         
backendService
dictionary
success
The default BackendService resource. Before forwarding the request to backendService, the loadbalancer applies any relevant headerActions specified as part of this backendServiceWeight.

         
headerAction

success
Specifies changes to request and response headers that need to take effect for the selected backendService. headerAction specified here take effect before headerAction in the enclosing HttpRouteRule, PathMatcher and UrlMap.

A list of header names for headers that need to be removed from the response prior to sending the response back to the client.

         
weight
integer
success
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 .

     
service
dictionary
success
The backend service resource to which traffic is directed if this rule is matched. If routeAction is additionally specified, advanced routing actions like URL Rewrites, etc. take effect prior to sending the request to the backend. However, if service is specified, routeAction cannot contain any weightedBackendService s. Conversely, if routeAction specifies any weightedBackendServices, service must not be specified. Only one of urlRedirect, service or routeAction.weightedBackendService must be set.

     
urlRedirect

success
When this rule is matched, the request is redirected to a URL specified by urlRedirect. If urlRedirect is specified, service or routeAction must not be set.

       
hostRedirect
string
success
The host that will be used in the redirect response instead of the one that was supplied in the request. The value must be between 1 and 255 characters.

       
httpsRedirect
boolean
success
If set to true, the URL scheme in the redirected request is set to https. If set to false, the URL scheme of the redirected request will remain the same as that of the request. This must only be set for UrlMaps used in TargetHttpProxys.
Setting this true for TargetHttpsProxy is not permitted. Defaults to false.

       
pathRedirect
string
success
The path that will be used in the redirect response instead of the one that was supplied in the request. Only one of pathRedirect or prefixRedirect must be specified. The value must be between 1 and 1024 characters.

* FOUND, which corresponds to 302.
* SEE_OTHER which corresponds to 303.
* TEMPORARY_REDIRECT, which corresponds to 307. In this case, the request method will be retained.
* PERMANENT_REDIRECT, which corresponds to 308. In this case, the request method will be retained.

       
stripQuery

success
If set to true, any accompanying query portion of the original URL is removed prior to redirecting the request. If set to false, the query portion of the original URL is retained. Defaults to false.
