    Server Load Balancer:CreateLoadBalancer

    Last Updated:Jul 12, 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

    There is currently no authorization information disclosed in the API.

    Request parameters

    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.
