Method: globalForwardingRules.get

Returns the specified GlobalForwardingRule resource. Gets a list of available forwarding rules by making a list() request.

HTTP request

GET https://www.googleapis.com/compute/v1/projects/{project}/global/forwardingRules/{resourceId}

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

resourceId

string

Name of the ForwardingRule resource to return.

Request body

The request body must be empty.

Response body

If successful, the response body contains data with the following structure:

A ForwardingRule resource. A ForwardingRule resource specifies which pool of target virtual machines to forward a packet to if it matches the given [IPAddress, IPProtocol, ports] tuple.

Fields
id

string (fixed64 format)

[Output Only] The unique identifier for the resource. This identifier is defined by the server.

creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.

name

string

Name of the resource; provided by the client when the resource is created. The name must be 1-63 characters long, and comply with RFC1035. Specifically, the name must be 1-63 characters long and match the regular expression [a-z]([-a-z0-9]*[a-z0-9])? which means the first character must be a lowercase letter, and all following characters must be a dash, lowercase letter, or digit, except the last character, which cannot be a dash.

description

string

An optional description of this resource. Provide this property when you create the resource.

region

string

[Output Only] URL of the region where the regional forwarding rule resides. This field is not applicable to global forwarding rules. You must specify this field as part of the HTTP request URL. It is not settable as a field in the request body.

IPAddress

string

The IP address that this forwarding rule is serving on behalf of.

Addresses are restricted based on the forwarding rule's load balancing scheme (EXTERNAL or INTERNAL) and scope (global or regional).

When the load balancing scheme is EXTERNAL, for global forwarding rules, the address must be a global IP, and for regional forwarding rules, the address must live in the same region as the forwarding rule. If this field is empty, an ephemeral IPv4 address from the same scope (global or regional) will be assigned. A regional forwarding rule supports IPv4 only. A global forwarding rule supports either IPv4 or IPv6.

When the load balancing scheme is INTERNAL_SELF_MANAGED, this must be a URL reference to an existing Address resource ( internal regional static IP address), with a purpose of GCE_END_POINT and addressType of INTERNAL.

When the load balancing scheme is INTERNAL, this can only be an RFC 1918 IP address belonging to the network/subnet configured for the forwarding rule. By default, if this field is empty, an ephemeral internal IP address will be automatically allocated from the IP range of the subnet or network configured for this forwarding rule.

An address can be specified either by a literal IP address or a URL reference to an existing Address resource. The following examples are all valid:

IPProtocol

enum

The IP protocol to which this rule applies. Valid options are TCP, UDP, ESP, AH, SCTP or ICMP.

When the load balancing scheme is INTERNAL, only TCP and UDP are valid. When the load balancing scheme is INTERNAL_SELF_MANAGED, only TCPis valid.

portRange

string

This field is used along with the target field for TargetHttpProxy, TargetHttpsProxy, TargetSslProxy, TargetTcpProxy, TargetVpnGateway, TargetPool, TargetInstance.

Applicable only when IPProtocol is TCP, UDP, or SCTP, only packets addressed to ports in the specified range will be forwarded to target. Forwarding rules with the same [IPAddress, IPProtocol] pair must have disjoint port ranges.

Some types of forwarding target have constraints on the acceptable ports:

  • TargetHttpProxy: 80, 8080
  • TargetHttpsProxy: 443
  • TargetTcpProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1688, 1883, 5222
  • TargetSslProxy: 25, 43, 110, 143, 195, 443, 465, 587, 700, 993, 995, 1688, 1883, 5222
  • TargetVpnGateway: 500, 4500

@pattern: \d+(?:-\d+)?

ports[]

string

This field is used along with the backendService field for internal load balancing.

When the load balancing scheme is INTERNAL, a single port or a comma separated list of ports can be configured. Only packets addressed to these ports will be forwarded to the backends configured with this forwarding rule.

You may specify a maximum of up to 5 ports.

@pattern: [\d+(, \d+)*]

target

string

The URL of the target resource to receive the matched traffic. For regional forwarding rules, this target must live in the same region as the forwarding rule. For global forwarding rules, this target must be a global load balancing resource. The forwarded traffic must be of a type appropriate to the target object. For INTERNAL_SELF_MANAGED" load balancing, only HTTP and HTTPS targets are valid.

loadBalancingScheme

enum

This signifies what the ForwardingRule will be used for and can only take the following values: INTERNAL, INTERNAL_SELF_MANAGED, EXTERNAL. The value of INTERNAL means that this will be used for Internal Network Load Balancing (TCP, UDP). The value of INTERNAL_SELF_MANAGED means that this will be used for Internal Global HTTP(S) LB. The value of EXTERNAL means that this will be used for External Load Balancing (HTTP(S) LB, External TCP/UDP LB, SSL Proxy)

subnetwork

string

This field is only used for INTERNAL load balancing.

For internal load balancing, this field identifies the subnetwork that the load balanced IP should belong to for this Forwarding Rule.

If the network specified is in auto subnet mode, this field is optional. However, if the network is in custom subnet mode, a subnetwork must be specified.

network

string

This field is not used for external load balancing.

For INTERNAL and INTERNAL_SELF_MANAGED load balancing, this field identifies the network that the load balanced IP should belong to for this Forwarding Rule. If this field is not specified, the default network will be used.

backendService

string

This field is only used for INTERNAL load balancing.

For internal load balancing, this field identifies the BackendService resource to receive the matched traffic.

networkTier

enum

This signifies the networking tier used for configuring this load balancer and can only take the following values: PREMIUM , STANDARD.

For regional ForwardingRule, the valid values are PREMIUM and STANDARD. For GlobalForwardingRule, the valid value is PREMIUM.

If this field is not specified, it is assumed to be PREMIUM. If IPAddress is specified, this value must be equal to the networkTier of the Address.

ipVersion

enum

The IP Version that will be used by this forwarding rule. Valid options are IPV4 or IPV6. This can only be specified for an external global forwarding rule.

kind

string

[Output Only] Type of the resource. Always compute#forwardingRule for Forwarding Rule resources.
