    Auto Scaling:CreateEciScalingConfiguration

    Last Updated:Sep 10, 2026

    Creates a scaling configuration of the Elastic Container Instance (ECI) type.

    Operation description

    Operation description

    A scaling configuration specifies the ECI instance template used for elastic scale-out.

    The Cpu and Memory parameters specify the range of instance types by defining the CPU and memory requirements. Auto Scaling determines the available instance types based on factors such as I/O optimization and zones, and then creates instances at the lowest price by sorting the instance types by price. This method applies only when the scaling group uses the cost optimization policy and no instance type is specified in the scaling configuration.

    Request parameters

    Parameter

    Type

    Required

    Description

    Example
    ScalingGroupId

    string

    Yes

    The ID of the scaling group to which the scaling configuration belongs.

    asg-bp14wlu85wrpchm0****
    ScalingConfigurationName

    string

    No

    The name of the scaling configuration. The name must be 2 to 64 characters in length and can contain letters, digits, underscores (_), hyphens (-), and periods (.). The name must start with a digit, letter, or Chinese character.

    The scaling configuration name must be unique within a scaling group in a region. If you do not specify this parameter, the scaling configuration ID is used by default.

    scalingconfig****
    SecurityGroupId

    string

    No

    ECI 实例所属的安全组 ID。同一个安全组内的 ECI 实例之间可以互相访问。

    如果没有指定安全组，系统将自动使用您选择的地域下的默认安全组，您需要确保该安全组的入方向规则中包含容器需要暴露的协议和端口。如果您在该地域下没有默认安全组，系统将自动创建一个默认安全组，并将您声明的容器协议和端口添加到该安全组的入方向规则中。

    sg-uf66jeqopgqa9hdn****
    ContainerGroupName

    string

    No

    The name of the ECI instance, which is also the container group name.

    To set sequential names, use the format name_prefix(AUTO_INCREMENT)[begin_number,bits]name_suffix.

    • name_prefix: the prefix of the hostname.

    • (AUTO_INCREMENT): a fixed value that indicates the sequential naming method.

    • begin_number: the start value of the sequential number. Valid values: [0,999999].

    • bits: the number of digits of the sequential number. Valid values: [1,6]. If the number of digits of begin_number is greater than the value of bits, bits defaults to 6.

    Note

    Set bits to at least 3. Otherwise, the sequential number may reach the upper limit. If the upper limit is reached and scale-out is still required, the scaling activity reports an error and stops the scale-out. In this case, you must reconfigure the hostname naming rule.

    • name_suffix (optional): the suffix of the hostname.

    Note

    [begin_number,bits] cannot contain spaces. The system increments the sequential number by default. However, if an ECI instance fails to start during scale-out, the scaling group removes the instance and creates a new one. As a result, the hostnames of ECI instances in the scaling group may not be consecutive.

    Example: If you set this parameter to nginx-test-(AUTO_INCREMENT)[0,3], the container group names are nginx-test-000, nginx-test-001, and nginx-test-002.

    The rules for setting sequential ECI instance names are the same as those for setting sequential ECS instance names. For more information, see Configure sequential and unique instance names or hostnames.

    nginx-test[0,3]

    string

    No
