VirtualHostService

Written by

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.

                  New list of domains to attribute 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.
                  Existing list of domains is completely replaced by the specified list.
                  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.

                  New list of 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.
                  Existing list of routes is completely replaced by the specified list, so if you just want to remove a route, make a VirtualHostService.RemoveRoute request.

                      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 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.

                      Idle timeout for an 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 timeout and idle_timeout is useful for implementing server-push mechanisms such as long polling, server-sent events (EventSource interface) etc.
                      If a connection times out, the load balancer responds to the client with a 504 Gateway Timeout status code.

                        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.

                        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).

                          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.

                          timeout google.protobuf.Duration
                          Overall timeout for an 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 connection times out, the load balancer responds to the client with a 504 Gateway Timeout status code.
                          Default value: 60.
                          idle_timeout google.protobuf.Duration
                          Idle timeout for an 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 timeout and idle_timeout is useful for implementing server-push mechanisms such as long polling, server-sent events (EventSource interface) etc.
                          If a connection times out, the load balancer responds to the client with a 504 Gateway Timeout status code.
                          If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see timeout).

                          Replacement for the path prefix matched by StringMatch.
                          For instance, if StringMatch.prefix_match value is /foo and replace_prefix value is /bar, a request with /foobaz path is forwarded with /barbaz path. For StringMatch.exact_match, the whole path is replaced.
                          If not specified, the path is not changed.

                                  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<UpdateRouteMetadata>
                                  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.

                                  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.

                                  Required. Backend group to forward requests to.
                                  timeout google.protobuf.Duration
                                  Overall timeout for an 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 connection times out, the load balancer responds to the client with a 504 Gateway Timeout status code.
                                  Default value: 60.
                                  idle_timeout google.protobuf.Duration
                                  Idle timeout for an 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 timeout and idle_timeout is useful for implementing server-push mechanisms such as long polling, server-sent events (EventSource interface) etc.
                                  If a connection times out, the load balancer responds to the client with a 504 Gateway Timeout status code.
                                  If not specified, no idle timeout is used, and an alive connection may be idle for any duration (see timeout).

                                  For instance, if StringMatch.prefix_match value is /foo and replace_prefix value is /bar, a request with /foobaz path is forwarded with /barbaz path. For StringMatch.exact_match, the whole path is replaced.
                                  If not specified, the path is not changed.

                                    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.
