Method: forwardingRules.aggregatedList

Retrieves an aggregated list of forwarding rules.

HTTP request

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

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters
project

string

Project ID for this request.

Query parameters

Parameters
maxResults

number (uint32 format)

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)

pageToken

string

Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.

filter

string

A filter expression that filters resources listed in the response. The expression must specify the field name, a comparison operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The comparison operator must be either =, !=, >, or <.

For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance.

You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels.

To filter on multiple expressions, provide each separate expression within parentheses. For example, (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake"). By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example, (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true).

orderBy

string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name.

You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first.

Currently, only sorting by name or creationTimestamp desc is supported.

Request body

The request body must be empty.

Fields
id

string

[Output Only] Unique identifier for the resource; defined by the server.

items[]

object

A list of ForwardingRulesScopedList resources.

items[].scopeName

string

Name of the scope containing this set of addresses.

items[].forwardingRules[]

object

A list of forwarding rules contained in this scope.

items[].forwardingRules[].id

string (fixed64 format)

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

items[].forwardingRules[].creationTimestamp

string

[Output Only] Creation timestamp in RFC3339 text format.

items[].forwardingRules[].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.

items[].forwardingRules[].description

string

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

items[].forwardingRules[].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.

items[].forwardingRules[].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:

items[].forwardingRules[].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.

items[].forwardingRules[].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+)?

items[].forwardingRules[].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+)*]

items[].forwardingRules[].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.

items[].forwardingRules[].selfLink

string

[Output Only] Server-defined URL for the resource.

items[].forwardingRules[].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)

items[].forwardingRules[].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.

items[].forwardingRules[].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.

items[].forwardingRules[].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.

items[].forwardingRules[].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.

items[].forwardingRules[].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.

items[].warning.data[]

object

[Output Only] Metadata about this warning in key: value format. For example:

"data": [  {  "key": "scope",  "value": "zones/us-east1-d"  }

items[].warning.data[].key

string

[Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be scope and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).

items[].warning.data[].value

string

[Output Only] A warning data value corresponding to the key.

nextPageToken

string

[Output Only] This token allows you to get the next page of results for list requests.
