    Parameter

    Type

    Description

    Example

    object

    The node group configuration, including instance specifications, disks, and scaling settings.

    NodeGroupType

    string

    The node group type. Valid values:

    • MASTER: Management node group.

    • CORE: Storage node group.

    • TASK: Compute node group.

    CORE
    NodeGroupName

    string

    The node group name. Maximum length is 128 characters. The name must be unique within the cluster.

    core-1
    PaymentType

    string

    The billing method of the node group. If not specified, it defaults to the billing method of the cluster. Valid values:

    • PayAsYouGo: Pay-as-you-go.

    • Subscription: Subscription.

    Default value: PayAsYouGo.

    PayAsYouGo
    SubscriptionConfig SubscriptionConfig

    The subscription configuration of the node group. If not specified, it defaults to the subscription configuration of the cluster.

    SpotStrategy

    string

    The strategy for spot instances. Valid values:

    • NoSpot: Regular pay-as-you-go instance.

    • SpotWithPriceLimit: Spot instance with a maximum price limit.

    • SpotAsPriceGo: Spot instance with the system automatically bidding up to the pay-as-you-go price.

    Default value: NoSpot.

    NoSpot
    SpotBidPrices

    array

    The bid price for spot instances. This parameter takes effect only when SpotStrategy is set to SpotWithPriceLimit. Valid values of N: 0 to 100.

    SpotBidPrice

    The bid settings for a spot instance type.

    VSwitchIds

    array

    The vSwitch IDs. Valid values of N: 1 to 20.

    ["vsw-hp35g7ya5ymw68mmg****"]

    string

    The vSwitch ID.

    vsw-hp35g7ya5ymw68mmg****
    WithPublicIp

    boolean

    Specifies whether to assign a public IP address. Valid values:

    • true: Assign a public IP address.

    • false: Do not assign a public IP address.

    Default value: false.

    false
    AdditionalSecurityGroupIds

    array

    The additional security groups. These are security groups configured specifically for the node group, in addition to the security groups configured for the cluster. Valid values of N: 0 to 2.

    ["sg-hp3abbae8lb6lmb1****"]

    string

    The security group ID.

    sg-hp3abbae8lb6lmb1****
    InstanceTypes

    array

    The node instance types. Valid values of N: 1 to 100.

    ["ecs.g6.xlarge"]

    string

    The node instance type.

    ecs.g7.2xlarge
    NodeCount

    integer

    The number of nodes. Valid values: 1 to 1000.

    3
    SystemDisk SystemDisk

    The system cloud disk.

    Default value: false.

    true
    CompensateWithOnDemand

    boolean

    Specifies whether to automatically attempt to create pay-as-you-go instances to meet the demand when nodeResizeStrategy is set to COST_OPTIMIZED and sufficient spot instances cannot be created due to price, inventory, or other reasons.

    true
