subnetworks

Patches the specified subnetwork with the data included in the request. Only certain fields can be updated with a patch request as indicated in the field descriptions. You must specify the current fingerprint of the subnetwork resource being patched.

patch/projects/{project}/regions/{region}/subnetworks/{subnetwork}

Path parameters

projectstring required

Project ID for this request.

regionstring required

Name of the region scoping this request.

subnetworkstring required

Name of the Subnetwork resource to patch.

Query parameters

drainTimeoutSecondsinteger

The drain timeout specifies the upper bound in seconds on the amount of time allowed to drain connections from the current ACTIVE subnetwork to the current BACKUP subnetwork. The drain timeout is only applicable when the following conditions are true:

  • the subnetwork being patched has purpose = INTERNAL_HTTPS_LOAD_BALANCER
  • the subnetwork being patched has role = BACKUP
  • the patch request is setting the role to ACTIVE. Note that after this patch operation the roles of the ACTIVE and BACKUP subnetworks will be swapped.
requestIdstring

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed.

For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments.

The request ID must be a valid UUID with the exception that zero UUID is not supported (00000000-0000-0000-0000-000000000000).

Request body

enableFlowLogsboolean

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 toREGIONAL_MANAGED_PROXY. It is recommended to uselogConfig.enable field instead.

stackType'IPV4_IPV6' | 'IPV4_ONLY' | 'IPV6_ONLY'

The stack type for the subnet. If set to IPV4_ONLY, new VMs in the subnet are assigned IPv4 addresses only. If set toIPV4_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 usingpatch.

idstring uint64

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

purpose'GLOBAL_MANAGED_PROXY' | 'INTERNAL_HTTPS_LOAD_BALANCER' | 'PEER_MIGRATION' | 'PRIVATE' | 'PRIVATE_NAT' | 'PRIVATE_RFC_1918' | 'PRIVATE_SERVICE_CONNECT' | 'REGIONAL_MANAGED_PROXY'
role'ACTIVE' | 'BACKUP'

The role of subnetwork. Currently, this field is only used when purpose is set to GLOBAL_MANAGED_PROXY orREGIONAL_MANAGED_PROXY. The value can be set toACTIVE 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.

externalIpv6Prefixstring

The external IPv6 address range that is owned by this subnetwork.

privateIpv6GoogleAccess'DISABLE_GOOGLE_ACCESS' | 'ENABLE_BIDIRECTIONAL_ACCESS_TO_GOOGLE' | 'ENABLE_OUTBOUND_VM_ACCESS_TO_GOOGLE'

This field is for internal use.

This field can be both set at resource creation time and updated usingpatch.

namestring

The name of the resource, provided by the client when initially creating the resource. The name must be 1-63 characters long, and comply withRFC1035. 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.

privateIpGoogleAccessboolean

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.

creationTimestampstring

Output only. [Output Only] Creation timestamp inRFC3339 text format.

allowSubnetCidrRoutesOverlapboolean

Whether this subnetwork's ranges can conflict with existing custom routes. Setting this to true allows this subnetwork's primary and secondary ranges to overlap with (and contain) custom routes that have already been configured on the corresponding network.

For example if a static route has range 10.1.0.0/16, a subnet range 10.0.0.0/8 could only be created if allow_conflicting_routes=true.

Overlapping is only allowed on subnetwork operations; routes whose ranges conflict with this subnetwork's ranges won't be allowed unless route.allow_conflicting_subnetworks is set to true.

Typically packets destined to IPs within the subnetwork (which may contain private/sensitive data) are prevented from leaving the virtual network. Setting this field to true will disable this feature.

The default value is false and applies to all existing subnetworks and automatically created subnetworks.

ipv6CidrRangestring

Output only. [Output Only] This field is for internal use.

state'DRAINING' | 'READY'

Output only. [Output Only] The state of the subnetwork, which can be one of the following values:READY: Subnetwork is created and ready to useDRAINING: only applicable to subnetworks that have the purpose set to INTERNAL_HTTPS_LOAD_BALANCER and indicates that connections to the load balancer are being drained. A subnetwork that is draining cannot be used or modified until it reaches a status ofREADY

reservedInternalRangestring

The URL of the reserved internal range.

regionstring

URL of the region where the Subnetwork resides. This field can be set only at resource creation time.

selfLinkstring

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

systemReservedExternalIpv6Rangesstring[]

Output only. [Output Only] The array of external IPv6 network ranges reserved from the subnetwork's external IPv6 range for system use.

ipCollectionstring

Reference to the source of IP, like a PublicDelegatedPrefix (PDP) for BYOIP. The PDP must be a sub-PDP in EXTERNAL_IPV6_SUBNETWORK_CREATION or INTERNAL_IPV6_SUBNETWORK_CREATION mode.

Use one of the following formats to specify a sub-PDP when creating a dual stack or IPv6-only subnetwork with external access using BYOIP:

Full resource URL, as inhttps://www.googleapis.com/compute/v1/projects/projectId/regions/region/publicDelegatedPrefixes/sub-pdp-name

Partial URL, as in

      - projects/projectId/regions/region/publicDelegatedPrefixes/sub-pdp-name
      - regions/region/publicDelegatedPrefixes/sub-pdp-name
ipCidrRangestring

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 theValid ranges list. The range can be expanded after creation usingexpandIpCidrRange.

networkstring

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.

ipv6GceEndpoint'VM_AND_FR' | 'VM_ONLY'

Output only. [Output Only] Possible endpoints of this subnetwork. It can be one of the following:

  • VM_ONLY: The subnetwork can be used for creating instances and IPv6 addresses with VM endpoint type. Such a subnetwork gets external IPv6 ranges from a public delegated prefix and cannot be used to create NetLb.
  • VM_AND_FR: The subnetwork can be used for creating both VM instances and Forwarding Rules. It can also be used to reserve IPv6 addresses with both VM and FR endpoint types. Such a subnetwork gets its IPv6 range from Google IP Pool directly.
ipv6AccessType'EXTERNAL' | 'INTERNAL'

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.

kindstring

Output only. [Output Only] Type of the resource. Always compute#subnetwork for Subnetwork resources.

gatewayAddressstring

Output only. [Output Only] The gateway address for default routes to reach destination addresses outside this subnetwork.

resolveSubnetMask'ARP_ALL_RANGES' | 'ARP_PRIMARY_RANGE'

Configures subnet mask resolution for this subnetwork.

systemReservedInternalIpv6Rangesstring[]

Output only. [Output Only] The array of internal IPv6 network ranges reserved from the subnetwork's internal IPv6 range for system use.

fingerprintstring byte

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.
