VirtualHostService

A set of methods for managing virtual hosts of HTTP routers.

Call	Description
Get	Returns the specified virtual host.
List	Lists virtual hosts of the specified HTTP router.
Create	Creates a virtual host in the specified HTTP router.
Update	Updates the specified virtual host of the specified HTTP router.
Delete	Deletes the specified virtual host.
RemoveRoute	Deletes the specified route from the specified virtual host.
UpdateRoute	Updates the specified route of the specified virtual host.

Calls VirtualHostService

Get

Returns the specified virtual host.
To get the list of all virtual hosts of an HTTP router, make a List request.

rpc Get (GetVirtualHostRequest) returns (VirtualHost)

GetVirtualHostRequest

Field	Description
http_router_id	string Required. ID of the HTTP router that the virtual host belongs to. To get the HTTP router ID, make a HttpRouterService.List request.
virtual_host_name	string Required. Name of the virtual host to return. To get the virtual host name, make a VirtualHostService.List request. Value must match the regular expression ([a-z]([-a-z0-9]{0,61}[a-z0-9])?)?.

VirtualHost

Field	Description
name	string Required. Name of the virtual host. The name is unique within the HTTP router.
authority[]	string List of domains that are attributed to the virtual host. The host is selected to process the request received by the load balancer if the domain specified in the HTTP/1.1 Host header or the HTTP/2 :authority pseudo-header matches a domain specified in the host. A wildcard asterisk character (*) matches 0 or more characters. If not specified, all domains are attributed to the host, which is the same as specifying a * value. An HTTP router must not contain more than one virtual host to which all domains are attributed.
routes[]	Route Routes of the virtual host. A route contains a set of conditions (predicates) that are used by the load balancer to select the route for the request and an action on the request. For details about the concept, see documentation. The order of routes matters: the first route whose predicate matches the request is selected. The most specific routes should be at the top of the list, so that they are not overridden. For example, if the first HTTP route is configured, via HttpRoute.match, to match paths prefixed with just /, other routes are never matched.
modify_request_headers[]	HeaderModification Deprecated, use route_options.modify_request_headers.
modify_response_headers[]	HeaderModification Deprecated, use route_options.modify_response_headers.
route_options	RouteOptions

action	oneof: route, redirect or direct_response Action performed on the request if the route is selected.
route	HttpRouteAction Forwards the request to a backend group for processing as configured.
redirect	RedirectAction Redirects the request as configured.
direct_response	DirectResponseAction Instructs the load balancer to respond directly as configured.

HttpRouteMatch

Field	Description

done	bool If the value is false, it means the operation is still in progress. If true, the operation is completed, and either error or response is available.
metadata	google.protobuf.Any<CreateVirtualHostMetadata> Service-specific metadata associated with the operation. It typically contains the ID of the target resource that the operation is performed on. Any method that returns a long-running operation should document the metadata type, if any.
result	oneof: error or response The operation result. If done == false and there was no failure detected, neither error nor response is set. If done == false and there was a failure detected, error is set. If done == true, exactly one of error or response is set.

Field	Description
name	string Required. Name of the virtual host. The name is unique within the HTTP router.
authority[]	string List of domains that are attributed to the virtual host. The host is selected to process the request received by the load balancer if the domain specified in the HTTP/1.1 Host header or the HTTP/2 :authority pseudo-header matches a domain specified in the host. A wildcard asterisk character (*) matches 0 or more characters. If not specified, all domains are attributed to the host, which is the same as specifying a * value. An HTTP router must not contain more than one virtual host to which all domains are attributed.
routes[]	Route Routes of the virtual host. A route contains a set of conditions (predicates) that are used by the load balancer to select the route for the request and an action on the request. For details about the concept, see documentation. The order of routes matters: the first route whose predicate matches the request is selected. The most specific routes should be at the top of the list, so that they are not overridden. For example, if the first HTTP route is configured, via HttpRoute.match, to match paths prefixed with just /, other routes are never matched.

response_code	enum RedirectResponseCode HTTP status code to use in redirect responses. MOVED_PERMANENTLY: 301 Moved Permanently status code. FOUND: 302 Found status code. SEE_OTHER: 303 See Other status code. TEMPORARY_REDIRECT: 307 Temporary Redirect status code. PERMANENT_REDIRECT: 308 Permanent Redirect status code.

DirectResponseAction

Field	Description
status	int64 HTTP status code to use in responses. Acceptable values are 100 to 599, inclusive.
body	Payload Response body.

Payload

Field	Description
payload	oneof: text Payload.
text	string Payload text. The string length in characters must be greater than 0.

GrpcRoute

Field	Description
match	GrpcRouteMatch Condition (predicate) used to select the route.
action	oneof: route or status_response Action performed on the request if the route is selected.
route	GrpcRouteAction Forwards the request to a backend group for processing as configured.
status_response	GrpcStatusResponseAction Instructs the load balancer to respond directly with a specified status.

GrpcRouteMatch

Field	Description
fqmn	StringMatch Match settings for gRPC service method called in the request. A match string must be a fully qualified method name, e.g. foo.bar.v1.BazService/Get, or a prefix of such. If not specified, the route matches all methods.

StringMatch

Field	Description
match	oneof: exact_match or prefix_match Match string for either exact or prefix match.
exact_match	string Exact match string.
prefix_match	string Prefix match string.

GrpcRouteAction

Field	Description
backend_group_id	string Required. Backend group to forward requests to.
max_timeout	google.protobuf.Duration Overall timeout for an underlying HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is kept alive for, regardless of whether data is transferred over it. If a client specifies a lower timeout in HTTP grpc-timeout header, the max_timeout value is ignored. If a connection times out, the load balancer responds to the client with an UNAVAILABLE status code. Default value: 60.
idle_timeout	google.protobuf.Duration Idle timeout for an underlying HTTP connection between a load balancer node an a backend from the backend group: the maximum time the connection is allowed to be idle, i.e. without any data transferred over it. Specifying meaningful values for both max_timeout and idle_timeout is useful for implementing server-push mechanisms such as long polling, server-sent events etc. If a connection times out, the load balancer responds to the client with an UNAVAILABLE status code. If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see max_timeout).
host_rewrite_specifier	oneof: host_rewrite or auto_host_rewrite Value rewrite settings for HTTP/1.1 Host headers and HTTP/2 :authority pseudo-headers. If not specified, the host is not changed.
host_rewrite	string Host replacement.
auto_host_rewrite	bool Automatically replaces the host with that of the target.

GrpcStatusResponseAction

Field	Description
status	enum Status gRPC status code to use in responses. OK: OK (0) status code. INVALID_ARGUMENT: INVALID_ARGUMENT (3) status code. NOT_FOUND: NOT_FOUND (5) status code. PERMISSION_DENIED: PERMISSION_DENIED (7) status code. UNAUTHENTICATED: UNAUTHENTICATED (16) status code. UNIMPLEMENTED: UNIMPLEMENTED (12) status code. INTERNAL: INTERNAL (13) status code. UNAVAILABLE: UNAVAILABLE (14) status code.
