Attributes

NameDescription
name str
Required. The name for this extension. The name is logged as part of the HTTP request logs. The name must conform with RFC-1034, is restricted to lower-cased letters, numbers and hyphens, and can have a maximum length of 63 characters. Additionally, the first character must be a letter and the last a letter or a number.
authority str
Optional. The :authority header in the gRPC request sent from Envoy to the extension service. Required for Callout extensions.
service str
Required. The reference to the service that runs the extension. Currently only callout extensions are supported here. To configure a callout extension, service must be a fully-qualified reference to a `backend service
supported_events MutableSequence[google.cloud.network_services_v1.types.EventType]
Optional. A set of events during request or response processing for which this extension is called. This field is required for the LbTrafficExtension resource. It's not relevant for the LbRouteExtension resource.
timeout google.protobuf.duration_pb2.Duration
Optional. Specifies the timeout for each individual message on the stream. The timeout must be between 10-1000 milliseconds. Required for Callout extensions.
fail_open bool
Optional. Determines how the proxy behaves if the call to the extension fails or times out. When set to TRUE, request or response processing continues without error. Any subsequent extensions in the extension chain are also executed. When set to FALSE or the default setting of FALSE is used, one of the following happens: - If response headers have not been delivered to the downstream client, a generic 500 error is returned to the client. The error response can be tailored by configuring a custom error response in the load balancer. - If response headers have been delivered, then the HTTP stream to the downstream client is reset.
forward_headers MutableSequence[str]
Optional. List of the HTTP headers to forward to the extension (from the client or backend). If omitted, all headers are sent. Each element is a string indicating the header name.
