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.

HTTP request

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

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.
`subnetwork`	`string` Name of the Subnetwork resource to patch.

project

string

Project ID for this request.

region

string

Name of the region scoping this request.

subnetwork

string

Name of the Subnetwork resource to patch.

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`).
`drainTimeoutSeconds`	`integer` 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.

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).

drainTimeoutSeconds

integer

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.

Fields
`kind`	`string` [Output Only] Type of the resource. Always `compute#subnetwork` for Subnetwork resources.
`id`	`string (uint64 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. 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 `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`.
`reservedInternalRange`	`string` The URL of the reserved internal range.
`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.
`secondaryIpRanges[].reservedInternalRange`	`string` The URL of the reserved internal range.
`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's ranges can conflict with existing static routes. Setting this to true allows this subnetwork's primary and secondary ranges to overlap with (and contain) static 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 allowConflictingRoutes=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. 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 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`.
`privateIpv6GoogleAccess`	`enum` This field is for internal use. This field can be both set at resource creation time and updated using `patch`.
`ipv6CidrRange`	`string` [Output Only] This field is for internal use.
`externalIpv6Prefix`	`string` The external IPv6 address range that is owned by this subnetwork.
`internalIpv6Prefix`	`string` The internal IPv6 address range that is owned by this subnetwork.
`purpose`	`enum` The purpose of the resource. This field can be either `PRIVATE`, `GLOBAL_MANAGED_PROXY`, `REGIONAL_MANAGED_PROXY`, `PEER_MIGRATION` or `PRIVATE_SERVICE_CONNECT`. `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. A subnet with purpose set to `PEER_MIGRATION` is used for subnet migration from one peered VPC to another. 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`	`enum` 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.
`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 determined by the org policy, if there is no org policy specified, then it will default to disabled. Flow logging isn't supported if the subnet `purpose` field is set to `REGIONAL_MANAGED_PROXY`.
`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 unless otherwise specified by the org policy, 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. The filter expression is used to define which VPC flow logs should be exported to Cloud Logging.
`stackType`	`enum` 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`.
`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.
`ipCollection`	`string` Reference to the source of IP, like a `PublicDelegatedPrefix` (PDP) for BYOIP. The PDP must be a sub-PDP in EXTERNAL_IPV6_SUBNETWORK_CREATION mode. Use one of the following formats to specify a sub-PDP when creating a dual stack subnetwork with external access using BYOIP: Full resource URL, as in `https://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`
`ipv6GceEndpoint`	`enum` [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.

Response body

Google Compute Engine has three Operation resources:

You can use an operation resource to manage asynchronous API requests. For more information, read Handling API responses.

Operations can be global, regional or zonal.

For global operations, use the globalOperations resource.
For regional operations, use the regionOperations resource.
For zonal operations, use the zoneOperations resource.

For more information, read Global, Regional, and Zonal Resources.

Note that completed Operation resources have a limited retention period.

If successful, the response body contains data with the following structure:

`progress`	`integer` [Output Only] An optional progress indicator that ranges from 0 to 100. There is no requirement that this be linear or support any granularity of operations. This should not be used to guess when the operation will be complete. This number should monotonically increase as the operation progresses.
`insertTime`	`string` [Output Only] The time that this operation was requested. This value is in RFC3339 text format.
`startTime`	`string` [Output Only] The time that this operation was started by the server. This value is in RFC3339 text format.
`endTime`	`string` [Output Only] The time that this operation was completed. This value is in RFC3339 text format.
`error`	`object` [Output Only] If errors are generated during processing of the operation, this field will be populated.
`error.errors[]`	`object` [Output Only] The array of errors encountered while processing this operation.
`error.errors[].code`	`string` [Output Only] The error type identifier for this error.
`error.errors[].location`	`string` [Output Only] Indicates the field in the request that caused the error. This property is optional.
`error.errors[].message`	`string` [Output Only] An optional, human-readable error message.
`error.errors[].errorDetails[]`	`object` [Output Only] An optional list of messages that contain the error details. There is a set of defined message types to use for providing details.The syntax depends on the error code. For example, QuotaExceededInfo will have details when the error code is QUOTA_EXCEEDED.

`error.errors[].errorDetails[].errorInfo.reason`	`string` The reason of the error. This is a constant value that identifies the proximate cause of the error. Error reasons are unique within a particular domain of errors. This should be at most 63 characters and match a regular expression of `[A-Z][A-Z0-9_]+[A-Z0-9]`, which represents UPPER_SNAKE_CASE.
`error.errors[].errorDetails[].errorInfo.domain`	`string` The logical grouping to which the "reason" belongs. The error domain is typically the registered service name of the tool or product that generates the error. Example: "pubsub.googleapis.com". If the error is generated by some common infrastructure, the error domain must be a globally unique value that identifies the infrastructure. For Google API infrastructure, the error domain is "googleapis.com".
`error.errors[].errorDetails[].errorInfo.metadatas`	`map (key: string, value: string)` Additional structured details about this error. Keys must match /[a-z][a-zA-Z0-9-_]+/ but should ideally be lowerCamelCase. Also they must be limited to 64 characters in length. When identifying the current value of an exceeded limit, the units should be contained in the key, not the value. For example, rather than {"instanceLimit": "100/request"}, should be returned as, {"instanceLimitPerRequest": "100"}, if the client exceeds the number of instances that can be created in a single (batch) request.

`warnings[]`	`object` [Output Only] If warning messages are generated during processing of the operation, this field will be populated.
`warnings[].code`	`enum` [Output Only] A warning code, if applicable. For example, Compute Engine returns `NO_RESULTS_ON_PAGE` if there are no results in the response.
`warnings[].message`	`string` [Output Only] A human-readable description of the warning code.
`warnings[].data[]`	`object` [Output Only] Metadata about this warning in `key: value` format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
`warnings[].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).
