public class ExtensionChainExtension : IDirectResponseSchema

Properties

Authority

Optional. The :authority header in the gRPC request sent from Envoy to the extension service. Required for Callout extensions. This field is not supported for plugin extensions. Setting it results in a validation error.

Declaration

[JsonProperty("authority")]
public virtual string Authority { get; set; }

Property Value

Type	Description
string

ETag

The ETag of the item.

Declaration

public virtual string ETag { get; set; }

Property Value

Type	Description
string

FailOpen

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.

Declaration

[JsonProperty("failOpen")]
public virtual bool? FailOpen { get; set; }

Property Value

Type	Description
bool?

ForwardHeaders

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.

public virtual IList<string> ForwardHeaders { get; set; }

Property Value

Type	Description
IList<string>

Metadata

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 is available under the namespace com.google..... For example: com.google.lb_traffic_extension.lbtrafficextension1.chain1.ext1. The following variables are supported in the metadata: {forwarding_rule_id} - substituted with the forwarding rule's fully qualified resource name. This field is not supported for plugin extensions. Setting it results in a validation error.

Declaration

[JsonProperty("metadata")]
public virtual IDictionary<string, object> Metadata { get; set; }

To configure a plugin extension, service must be a reference to a WasmPlugin resource in the format: projects/{project}/locations/{location}/wasmPlugins/{plugin} or //networkservices.googleapis.com/projects/{project}/locations/{location}/wasmPlugins/{wasmPlugin}. Plugin extensions are currently supported for the LbTrafficExtension and the LbRouteExtension resources.
