    API Description

    This API is used to create a CLB instance. To use the CLB service, you first need to purchase one or more instances. After this API call succeeds, a unique instance ID will be returned. There are two types of instances: public network and private network instances. For more information, see the “network types” in CLB Attributes Selection.
    Domain name for API calls: lb.api.qcloud.com

    Request Parameters

    The list below contains only the API request parameters. Common parameters should be added when you call the API. For more information, see Common Request Parameters. The Action field for this API is CreateLoadBalancer.

    Required
    Type
    Description
    loadBalancerType
    No
    Int
    Network type of the CLB instance.
    2: public network; 3: private network.
    forward
    No
    Int
    CLB instance type. 1: CLB; 0: Cassic CLB. Default value: 0.
    loadBalancerName
    No
    String
    CLB instance name, which takes effect only when an instance is created. Rule: 1-50 letters, Chinese, digits, dashes (-), or underscores (_).
    Note: If this name is the same as that of an existing CLB instance, the system will automatically generate a name for this newly created instance.
    domainPrefix
    No
    String
    Domain name prefix. The domain name of the CLB instance consists of the user-defined domain prefix and the domain suffix automatically generated by Tencent Cloud to ensure the uniqueness. This field is only applicable to Classic CLB instances.
    Rule: 1-20 lowercase letters, digits or dashes (-). This field is inapplicable to private network CLB.
    Note: if this domain name prefix is the same as that of an existing CLB instance, the system will automatically generate a domain name prefix for this newly created instance. For example, you only need to enter the prefix "xxxxx" for xxxxx.region.appId.clb.myqcloud.com.
    vpcId
    No
    String
    Network ID of the CLB instance, which can be obtained via the DescribeVpcEx API. If no value or “0” is passed in, the network is Classic Network.
    subnetId
    No
    Int
    A subnet ID specified when you purchase a private network CLB instance in a VPC. The VIP of this instance will be generated in the subnet. This parameter can be left empty in other cases.
    projectId
    No
    Int
    ID of the project to which a CLB instance belongs, which can be obtained via the DescribeProjects API. If this parameter is not passed in, the default project will be used.
