|
|---|---|
| Name | Description |
custom_error_response_policy |
google.cloud.compute_v1beta.types.CustomErrorResponsePolicy
customErrorResponsePolicy specifies how the Load Balancer returns error responses when BackendServiceorBackendBucket responds with an error. If a policy for an error code is not configured for the RouteRule, a policy for the error code configured inpathMatcher.defaultCustomErrorResponsePolicy is applied. If one is not specified inpathMatcher.defaultCustomErrorResponsePolicy, the policy configured in UrlMap.defaultCustomErrorResponsePolicy takes effect. For example, consider a UrlMap with the following configuration: :: - UrlMap.defaultCustomErrorResponsePolicy are configured with policies for 5xx and 4xx errors - A RouteRule for /coming_soon/ is configured for the error code 404. If the request is for www.myotherdomain.com and a404 is encountered, the policy underUrlMap.defaultCustomErrorResponsePolicy takes effect. If a404 response is encountered for the requestwww.example.com/current_events/, the pathMatcher's policy takes effect. If however, the request forwww.example.com/coming_soon/ encounters a 404, the policy in RouteRule.customErrorResponsePolicy takes effect. If any of the requests in this example encounter a 500 error code, the policy atUrlMap.defaultCustomErrorResponsePolicy takes effect. When used in conjunction withrouteRules.routeAction.retryPolicy, retries take precedence. Only once all retries are exhausted, thecustomErrorResponsePolicy is applied. While attempting a retry, if load balancer is successful in reaching the service, the customErrorResponsePolicy is ignored and the response from the service is returned to the client. customErrorResponsePolicy is supported only for global external Application Load Balancers. This field is a member of oneof_ _custom_error_response_policy.
|
description |
str
The short description conveying the intent of this routeRule. The description can have a maximum length of 1024 characters. This field is a member of oneof_ _description.
|
header_action |
google.cloud.compute_v1beta.types.HttpHeaderAction
Specifies changes to request and response headers that need to take effect for the selected backendService. The headerAction value specified here is applied before the matching pathMatchers[].headerAction and afterpathMatchers[].routeRules[].routeAction.weightedBackendService.backendServiceWeightAction[].headerAction HeaderAction is not supported for load balancers that have their loadBalancingScheme set to EXTERNAL. Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true. This field is a member of oneof_ _header_action.
|
http_filter_configs |
MutableSequence[google.cloud.compute_v1beta.types.HttpFilterConfig]
Outbound route specific configuration fornetworkservices.HttpFilter resources enabled by Traffic Director. httpFilterConfigs only applies for load balancers with loadBalancingScheme set toINTERNAL_SELF_MANAGED. See ForwardingRule for more details. Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true. |
http_filter_metadata |
MutableSequence[google.cloud.compute_v1beta.types.HttpFilterConfig]
Outbound route specific metadata supplied tonetworkservices.HttpFilter resources enabled by Traffic Director. httpFilterMetadata only applies for load balancers with loadBalancingScheme set toINTERNAL_SELF_MANAGED. See ForwardingRule for more details. The only configTypeUrl supported istype.googleapis.com/google.protobuf.Struct Not supported when the URL map is bound to a target gRPC proxy that has validateForProxyless field set to true. |
match_rules |
MutableSequence[google.cloud.compute_v1beta.types.HttpRouteRuleMatch]
The list of criteria for matching attributes of a request to thisrouteRule. This list has OR semantics: the request matches this routeRule when any of thematchRules are satisfied. However predicates within a given matchRule have AND semantics. All predicates within a matchRule must match for the request to match the rule. |
priority |
int
For routeRules within a given pathMatcher, priority determines the order in which a load balancer interpretsrouteRules. RouteRules are evaluated in order of priority, from the lowest to highest number. The priority of a rule decreases as its number increases (1, 2, 3, N+1). The first rule that matches the request is applied. You cannot configure two or more routeRules with the same priority. Priority for each rule must be set to a number from 0 to 2147483647 inclusive. Priority numbers can have gaps, which enable you to add or remove rules in the future without affecting the rest of the rules. For example, 1, 2, 3, 4, 5, 9, 12, 16 is a valid series of priority numbers to which you could add rules numbered from 6 to 8, 10 to 11, and 13 to 15 in the future without any impact on existing rules. This field is a member of oneof_ _priority.
|
route_action |
google.cloud.compute_v1beta.types.HttpRouteAction
In response to a matching matchRule, the load balancer performs advanced routing actions, such as URL rewrites and header transformations, before forwarding the request to the selected backend. Only one of urlRedirect, service orrouteAction.weightedBackendService can be set. URL maps for classic Application Load Balancers only support the urlRewrite action within a route rule'srouteAction. This field is a member of oneof_ _route_action.
|
service |
str
The full or partial URL of the backend service resource to which traffic is directed if this rule is matched. If routeAction is also specified, advanced routing actions, such as URL rewrites, take effect before sending the request to the backend. Only one of urlRedirect, service orrouteAction.weightedBackendService can be set. This field is a member of oneof_ _service.
|
url_redirect |
google.cloud.compute_v1beta.types.HttpRedirectAction
When this rule is matched, the request is redirected to a URL specified by urlRedirect. Only one of urlRedirect, service orrouteAction.weightedBackendService can be set. Not supported when the URL map is bound to a target gRPC proxy. This field is a member of oneof_ _url_redirect.
