Domain name for API request: clb.tencentcloudapi.com.
This API (CreateLoadBalancer) is used to create a CLB instance. To use the CLB service, you first need to purchase one or more instances. After this API is called successfully, a unique instance ID will be returned. There are two types of instances: public network and private network. For more information, see the product types in the product documentation.
Note: (1) To apply for a CLB instance in the specified AZ and cross-AZ disaster recovery, please submit a ticket; (2) Currently, IPv6 is supported only in Beijing, Shanghai, and Guangzhou regions.
This is an async API. After it is returned successfully, you can call the DescribeLoadBalancers API to query the status of the instance (such as creating and normal) to check whether it is successfully created.
A maximum of 20 requests can be initiated per second for this API.
Note: This API supports Finance regions. If the common parameter Region is a Finance region, a domain name with the Finance region needs to be specified, for example: clb.ap-shanghai-fsi.tencentcloudapi.com
The following request parameter list only provides API request parameters and some common parameters. For the complete common parameter list, see Common Request Parameters.
| Parameter Name | Required | Type | Description |
|---|---|---|---|
| Action | Yes | String | Common parameter. The value used for this API: CreateLoadBalancer. |
| Version | Yes | String | Common parameter. The value used for this API: 2018-03-17. |
| Region | Yes | String | Common parameter. For more information, please see the list of regions supported by the product. |
| LoadBalancerType | Yes | String | CLB instance network type: OPEN: public network; INTERNAL: private network. |
| Forward | No | Integer | CLB instance type. 1: generic CLB instance. Currently, only 1 can be passed in |
| LoadBalancerName | No | String | CLB instance name, which takes effect only when an instance is created. Rule: 1-50 letters, digits, dashes (-), or underscores (_). Note: If this name is the same as the name of an existing CLB instance in the system, the system will automatically generate a name for this newly created instance. |
| VpcId | No | String | Network ID of the backend target server of CLB, which can be obtained through the DescribeVpcEx API. If this parameter is not passed in, it will default to a basic network ("0"). |
| SubnetId | No | String | A subnet ID must be specified when you purchase a private network CLB instance in a VPC, and the VIP of this instance will be generated in this subnet. |
| ProjectId | No | Integer | ID of the project to which a CLB instance belongs, which can be obtained through the DescribeProject API. If this parameter is not passed in, the default project will be used. |
| AddressIPVersion | No | String | IP version. Valid values: IPv4, IPv6, IPv6FullChain. Default value: IPv4. This parameter is applicable only to public network CLB instances. |
| Number | No | Integer | Number of CLBs to be created. Default value: 1. |
| MasterZoneId | No | String | Sets the primary AZ ID for cross-AZ disaster recovery, such as 100001 or ap-guangzhou-1, which is applicable only to public network CLB. Note: A primary AZ carries traffic, while a secondary AZ does not carry traffic by default and will be used only if the primary AZ becomes unavailable. The platform will automatically select the optimal secondary AZ. The list of primary AZs in a specific region can be queried through the DescribeMasterZones API. |
| ZoneId | No | String | Specifies an AZ ID for creating a CLB instance, such as ap-guangzhou-1, which is applicable only to public network CLB. |
| InternetAccessible | No | InternetAccessible | CLB network billing mode. This parameter is applicable only to public network CLB instances. |
| VipIsp | No | String | This parameter is applicable only to public network CLB instances. Valid values: CMCC (China Mobile), CTCC (China Telecom), CUCC (China Unicom). If this parameter is not specified, BGP will be used by default. ISPs supported in a region can be queried with the DescribeSingleIsp API. If an ISP is specified, only bill-by-bandwidth-package (BANDWIDTH_PACKAGE) can be used as the network billing mode. |
| Tags.N | No | Array of TagInfo | Tags a CLB instance when purchasing it |
| ClientToken | No | String | A unique string supplied by the client to ensure that the request is idempotent. Its maximum length is 64 ASCII characters. If this parameter is not specified, the idempotency of the request cannot be guaranteed. |
| Parameter Name | Type | Description |
|---|---|---|
| LoadBalancerIds | Array of String | Array of unique CLB instance IDs. |
| RequestId | String | The unique request ID, which is returned for each request. RequestId is required for locating a problem. |
