    Server Load Balancer:CreateLoadBalancer

    Last Updated:Mar 01, 2024

    Creates an Application Load Balancer (ALB) instance in a region.

    Operation description

    CreateLoadBalancer is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the GetLoadBalancerAttribute operation to query the status of an ALB instance.

    • If an ALB instance is in the Provisioning state, it indicates that the ALB instance is being created.
    • If an ALB instance is in the Active state, it indicates that the ALB instance is created.

    Debugging

    OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

    ParameterTypeRequiredDescriptionExample
    ClientTokenstringNo

    The client token that is used to ensure the idempotence of the request.

    You can use the client to generate the value, but you must ensure that it is unique among different requests. The token can only contain ASCII characters.

    Note If you do not specify this parameter, the system uses the value of RequestId as the value of ClientToken. The value of the RequestId parameter may be different for each API request.

    DryRunbooleanNo

    Specifies whether to perform a dry run. Default value: false. Valid values:

    • true: performs a dry run. The system checks the required parameters, request format, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned.
    • false: performs a dry run and sends the request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.
