Network Services v1 API - Class LbTrafficExtension (1.3.0)

Reference documentation and code samples for the Network Services v1 API class LbTrafficExtension.

LbTrafficExtension is a resource that lets the extension service modify the headers and payloads of both requests and responses without impacting the choice of backend services or any other security policies associated with the backend service.

Output only. The timestamp when the resource was created.

Optional. A human-readable description of the resource.

Required. A set of ordered extension chains that contain the match conditions and extensions to execute. Match conditions for each extension chain are evaluated in sequence for a given request. The first extension chain that has a condition that matches the request is executed. Any subsequent extension chains do not execute. Limited to 5 extension chains per resource.

Optional. A list of references to the forwarding rules to which this service extension is attached. At least one forwarding rule is required. Only one LbTrafficExtension resource can be associated with a forwarding rule.

Optional. Set of labels associated with the LbTrafficExtension resource.

The format must comply with the requirements for labels for Google Cloud resources.

LbTrafficExtensionName-typed view over the Name resource name property.

Required. All backend services and forwarding rules referenced by this extension must share the same load balancing scheme. Supported values: INTERNAL_MANAGED and EXTERNAL_MANAGED. For more information, refer to Backend services overview.

Optional. The metadata provided here is included as part of the metadata_context (of type google.protobuf.Struct) in the ProcessingRequest message sent to the extension server.

The metadata applies to all extensions in all extensions chains in this resource.

The metadata is available under the key com.google.lb_traffic_extension.<resource_name>.

The following variables are supported in the metadata:

{forwarding_rule_id} - substituted with the forwarding rule's fully qualified resource name.

This field must not be set if at least one of the extension chains contains plugin extensions. Setting it results in a validation error.

You can set metadata at either the resource level or the extension level. The extension level metadata is recommended because you can pass a different set of metadata through each extension to the backend.

Required. Identifier. Name of the LbTrafficExtension resource in the following format: projects/{project}/locations/{location}/lbTrafficExtensions/{lb_traffic_extension}.

Output only. The timestamp when the resource was updated.
