Attributes
Name	Description
creation_timestamp	str [Output Only] Creation timestamp in RFC3339 text format. This field is a member of oneof_ _creation_timestamp.
description	str An optional description of this resource. Provide this property when you create the resource. This field can be set only at resource creation time. This field is a member of oneof_ _description.
enable_flow_logs	bool 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 determined by the org policy, if there is no org policy specified, then it will default to disabled. This field isn't supported if the subnet purpose field is set to REGIONAL_MANAGED_PROXY. This field is a member of oneof_ _enable_flow_logs.
external_ipv6_prefix	str The external IPv6 address range that is owned by this subnetwork. This field is a member of oneof_ _external_ipv6_prefix.
fingerprint	str 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. This field is a member of oneof_ _fingerprint.
gateway_address	str [Output Only] The gateway address for default routes to reach destination addresses outside this subnetwork. This field is a member of oneof_ _gateway_address.
id	int [Output Only] The unique identifier for the resource. This identifier is defined by the server. This field is a member of oneof_ _id.
internal_ipv6_prefix	str The internal IPv6 address range that is owned by this subnetwork. This field is a member of oneof_ _internal_ipv6_prefix.
ip_cidr_range	str 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 100.64.0.0/10. Ranges must be unique and non-overlapping within a network. Only IPv4 is supported. This field is set at resource creation time. The range can be any range listed in the Valid ranges list. The range can be expanded after creation using expandIpCidrRange. This field is a member of oneof_ _ip_cidr_range.
ipv6_access_type	str The access type of IPv6 address this subnet holds. It's immutable and can only be specified during creation or the first time the subnet is updated into IPV4_IPV6 dual stack. Check the Ipv6AccessType enum for the list of possible values. This field is a member of oneof_ _ipv6_access_type.
ipv6_cidr_range	str [Output Only] This field is for internal use. This field is a member of oneof_ _ipv6_cidr_range.
kind	str [Output Only] Type of the resource. Always compute#subnetwork for Subnetwork resources. This field is a member of oneof_ _kind.
log_config	google.cloud.compute_v1.types.SubnetworkLogConfig This field denotes the VPC flow logging options for this subnetwork. If logging is enabled, logs are exported to Cloud Logging. This field is a member of oneof_ _log_config.
name	str 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. This field is a member of oneof_ _name.
network	str The URL of the network to which this subnetwork belongs, provided by the client when initially creating the subnetwork. This field can be set only at resource creation time. This field is a member of oneof_ _network.
private_ip_google_access	bool 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. This field is a member of oneof_ _private_ip_google_access.
private_ipv6_google_access	str This field is for internal use. This field can be both set at resource creation time and updated using patch. Check the PrivateIpv6GoogleAccess enum for the list of possible values. This field is a member of oneof_ _private_ipv6_google_access.
purpose	str The purpose of the resource. This field can be either PRIVATE, GLOBAL_MANAGED_PROXY, REGIONAL_MANAGED_PROXY, PRIVATE_SERVICE_CONNECT, or PRIVATE is the default purpose for user-created subnets or subnets that are automatically created in auto mode networks. Subnets with purpose set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY are user-created subnetworks that are reserved for Envoy-based load balancers. A subnet with purpose set to PRIVATE_SERVICE_CONNECT is used to publish services using Private Service Connect. If unspecified, the subnet purpose defaults to PRIVATE. The enableFlowLogs field isn't supported if the subnet purpose field is set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY. Check the Purpose enum for the list of possible values. This field is a member of oneof_ _purpose.
region	str URL of the region where the Subnetwork resides. This field can be set only at resource creation time. This field is a member of oneof_ _region.
reserved_internal_range	str The URL of the reserved internal range. This field is a member of oneof_ _reserved_internal_range.
role	str The role of subnetwork. Currently, this field is only used when purpose is set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY. The value can be set to ACTIVE or BACKUP. An ACTIVE subnetwork is one that is currently being used for Envoy-based load balancers in a region. A BACKUP subnetwork is one that is ready to be promoted to ACTIVE or is currently draining. This field can be updated with a patch request. Check the Role enum for the list of possible values. This field is a member of oneof_ _role.
secondary_ip_ranges	MutableSequence[google.cloud.compute_v1.types.SubnetworkSecondaryRange] 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.
self_link	str [Output Only] Server-defined URL for the resource. This field is a member of oneof_ _self_link.

This field is for internal use. This field can be both set at resource creation time and updated using patch.

Purpose

Purpose(value)

The purpose of the resource. This field can be either PRIVATE, GLOBAL_MANAGED_PROXY, REGIONAL_MANAGED_PROXY, PRIVATE_SERVICE_CONNECT, or PRIVATE is the default purpose for user-created subnets or subnets that are automatically created in auto mode networks. Subnets with purpose set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY are user-created subnetworks that are reserved for Envoy-based load balancers. A subnet with purpose set to PRIVATE_SERVICE_CONNECT is used to publish services using Private Service Connect. If unspecified, the subnet purpose defaults to PRIVATE. The enableFlowLogs field isn't supported if the subnet purpose field is set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY.

Role

Role(value)

The role of subnetwork. Currently, this field is only used when purpose is set to GLOBAL_MANAGED_PROXY or REGIONAL_MANAGED_PROXY. The value can be set to ACTIVE or BACKUP. An ACTIVE subnetwork is one that is currently being used for Envoy-based load balancers in a region. A BACKUP subnetwork is one that is ready to be promoted to ACTIVE or is currently draining. This field can be updated with a patch request.

StackType

StackType(value)

The stack type for the subnet. If set to IPV4_ONLY, new VMs in the subnet are assigned IPv4 addresses only. If set to IPV4_IPV6, new VMs in the subnet can be assigned both IPv4 and IPv6 addresses. If not specified, IPV4_ONLY is used. This field can be both set at resource creation time and updated using patch.
