HTTP request

POST https://compute.googleapis.com/compute/beta/projects/{project}/regions/{region}/subnetworks

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`region`	`string` Name of the region scoping this request.

project

string

Project ID for this request.

region

string

Name of the region scoping this request.

Query parameters

Parameters

Parameters
`requestId`	`string` 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`).

requestId

string

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).

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. Authorization requires the following IAM permission on the specified resource `network`: `compute.networks.updatePolicy`
`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 `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`.
`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. The range can be any range listed in the Valid ranges list.
`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.
`allowSubnetCidrRoutesOverlap`	`boolean` Whether this subnetwork can conflict with static routes. Setting this to true allows this subnetwork's primary and secondary ranges to conflict with routes that have already been configured on the corresponding network. Static routes will take precedence over the subnetwork route if the route prefix length is at least as large as the subnetwork prefix length. Also, packets destined to IPs within subnetwork may contain private/sensitive data and 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. This field cannot be set to true at resource creation time.
`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. This field isn't supported with the `purpose` field set to `INTERNAL_HTTPS_LOAD_BALANCER`.
`privateIpv6GoogleAccess`	`enum` The private IPv6 google access type for the VMs in this subnet. This is an expanded field of enablePrivateV6Access. If both fields are set, privateIpv6GoogleAccess will take priority. This field can be both set at resource creation time and updated using `patch`.
`ipv6CidrRange`	`string` [Output Only] The range of internal IPv6 addresses that are owned by this subnetwork.
`externalIpv6Prefix`	`string` [Output Only] The range of external IPv6 addresses that are owned by this subnetwork.
`purpose`	`enum` The purpose of the resource. This field can be either `PRIVATE_RFC_1918` or `INTERNAL_HTTPS_LOAD_BALANCER`. A subnetwork with purpose set to `INTERNAL_HTTPS_LOAD_BALANCER` is a user-created subnetwork that is reserved for Internal HTTP(S) Load Balancing. If unspecified, the purpose defaults to `PRIVATE_RFC_1918`. The `enableFlowLogs` field isn't supported with the `purpose` field set to `INTERNAL_HTTPS_LOAD_BALANCER`.
`role`	`enum` The role of subnetwork. Currently, this field is only used when purpose = `INTERNAL_HTTPS_LOAD_BALANCER`. The value can be set to `ACTIVE` or `BACKUP`. An `ACTIVE` subnetwork is one that is currently being used for Internal HTTP(S) Load Balancing. 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.
`state`	`enum` [Output Only] The state of the subnetwork, which can be one of the following values: `READY`: Subnetwork is created and ready to use `DRAINING`: 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 of `READY`
`logConfig`	`object` This field denotes the VPC flow logging options for this subnetwork. If logging is enabled, logs are exported to Cloud Logging.
`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 `EXCLUDE_ALL_METADATA`.
`logConfig.metadataFields[]`	`string` Can only be specified if VPC flow logs for this subnetwork is enabled and "metadata" was set to CUSTOM_METADATA.
`logConfig.filterExpr`	`string` Can only be specified if VPC flow logs for this subnetwork is enabled. instantSnapshots.export filter used to define which VPC flow logs should be logged.
`stackType`	`enum` The stack type for this subnet to identify whether the IPv6 feature is enabled or not. If not specified `IPV4_ONLY` will be used. This field can be both set at resource creation time and updated using `patch`.
`ipv6AccessType`	`enum` 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. If the ipv6_type is EXTERNAL then this subnet cannot enable direct path.
`stackType`	`enum` The stack type for this subnet to identify whether the IPv6 feature is enabled or not. If not specified `IPV4_ONLY` will be used. This field can be both set at resource creation time and updated using `patch`.
`ipv6AccessType`	`enum` 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. If the ipv6_type is EXTERNAL then this subnet cannot enable direct path.
`kind`	`string` [Output Only] Type of the resource. Always `compute#subnetwork` for Subnetwork resources.
