Resource: Subnetwork

Represents a Subnetwork resource.

A subnetwork (also known as a subnet) is a logical partition of a Virtual Private Cloud network with one primary IP range and zero or more secondary IP ranges. For more information, read Virtual Private Cloud (VPC) Network.

JSON representation

{ "id": string, "creationTimestamp": string, "name": string, "description": string, "network": string, "ipCidrRange": string, "gatewayAddress": string, "region": string, "selfLink": string, "privateIpGoogleAccess": boolean, "secondaryIpRanges": [ { "rangeName": string, "ipCidrRange": string } ], "fingerprint": string, "enableFlowLogs": boolean, "logConfig": { "enable": boolean, "aggregationInterval": enum, "flowSampling": number, "metadata": enum }, "kind": string }

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 The name of the resource, provided by the client when initially creating the resource. 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. This field can be set only at resource creation time.
network	string The URL of the network to which this subnetwork belongs, provided by the client when initially creating the subnetwork. Only networks that are in the distributed mode can have subnetworks. This field can be set only at resource creation time.
ipCidrRange	string The range of internal addresses that are owned by this subnetwork. Provide this property when you create the subnetwork. For example, 10.0.0.0/8 or 192.168.0.0/16. Ranges must be unique and non-overlapping within a network. Only IPv4 is supported. This field can be set only at resource creation time.
gatewayAddress	string [Output Only] The gateway address for default routes to reach destination addresses outside this subnetwork.
region	string URL of the region where the Subnetwork resides. This field can be set only at resource creation time.
selfLink	string [Output Only] Server-defined URL for the resource.
privateIpGoogleAccess	boolean Whether the VMs in this subnet can access Google services without assigned external IP addresses. This field can be both set at resource creation time and updated using setPrivateIpGoogleAccess.
secondaryIpRanges[]	object An array of configurations for secondary IP ranges for VM instances contained in this subnetwork. The primary IP of such VM must belong to the primary ipCidrRange of the subnetwork. The alias IPs may belong to either primary or secondary ranges. This field can be updated with a patch request.
secondaryIpRanges[].rangeName	string The name associated with this subnetwork secondary range, used when adding an alias IP range to a VM instance. The name must be 1-63 characters long, and comply with RFC1035. The name must be unique within the subnetwork.
secondaryIpRanges[].ipCidrRange	string The range of IP addresses belonging to this subnetwork secondary range. Provide this property when you create the subnetwork. Ranges must be unique and non-overlapping with all primary and secondary IP ranges within a network. Only IPv4 is supported.
fingerprint	string (bytes format) Fingerprint of this resource. A hash of the contents stored in this object. This field is used in optimistic locking. This field will be ignored when inserting a Subnetwork. An up-to-date fingerprint must be provided in order to update the Subnetwork, otherwise the request will fail with error 412 conditionNotMet. To see the latest fingerprint, make a get() request to retrieve a Subnetwork. A base64-encoded string.
enableFlowLogs	boolean Whether to enable flow logging for this subnetwork. If this field is not explicitly set, it will not appear in get listings. If not set the default behavior is to disable flow logging.
logConfig	object This field denotes the VPC flow logging options for this subnetwork. If logging is enabled, logs are exported to Stackdriver.
logConfig.enable	boolean Whether to enable flow logging for this subnetwork. If this field is not explicitly set, it will not appear in get listings. If not set the default behavior is to disable flow logging.
logConfig.aggregationInterval	enum Can only be specified if VPC flow logging for this subnetwork is enabled. Toggles the aggregation interval for collecting flow logs. Increasing the interval time will reduce the amount of generated flow logs for long lasting connections. Default is an interval of 5 seconds per connection.
logConfig.flowSampling	number Can only be specified if VPC flow logging for this subnetwork is enabled. The value of the field must be in [0, 1]. Set the sampling rate of VPC flow logs within the subnetwork where 1.0 means all collected logs are reported and 0.0 means no logs are reported. Default is 0.5, which means half of all collected logs are reported.
logConfig.metadata	enum Can only be specified if VPC flow logs for this subnetwork is enabled. Configures whether all, none or a subset of metadata fields should be added to the reported VPC flow logs. Default is INCLUDE_ALL_METADATA.
kind	string [Output Only] Type of the resource. Always compute#subnetwork for Subnetwork resources.
