clusterId^Required

public readonly clusterId: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property clusterId: Cluster ID.

---

enableAutoGrow^Optional

public readonly enableAutoGrow: boolean | IResolvable;

• Type: boolean | @alicloud/ros-cdk-core.IResolvable

Property enableAutoGrow: Specifies whether to enable auto scale-out.

Valid values: true: enables auto scale-out. false: disables auto scale-out Default value: false

---

enableAutoShrink^Optional

public readonly enableAutoShrink: boolean | IResolvable;

• Type: boolean | @alicloud/ros-cdk-core.IResolvable

Property enableAutoShrink: Specifies whether to enable auto scale-in.

Valid values: true: enables auto scale-in. false: disables auto scale-in Default value: false

---

excludeNodes^Optional

public readonly excludeNodes: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property excludeNodes: The compute nodes that are excluded from the list of auto scaling nodes.

Separate multiple compute nodes with commas (,). If you want to retain a compute node, you can set the node as an exceptional node. Then, the node is not released if it is idle.

---

extraNodesGrowRatio^Optional

public readonly extraNodesGrowRatio: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property extraNodesGrowRatio: The percentage of extra compute nodes.

Default value: 0

---

growIntervalInMinutes^Optional

public readonly growIntervalInMinutes: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property growIntervalInMinutes: The interval between two consecutive rounds of scale-out.

Unit: minutes. Default value: 2

---

growRatio^Optional

public readonly growRatio: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property growRatio: The percentage of each round of scale-out.

Default value: 100

---

growTimeoutInMinutes^Optional

public readonly growTimeoutInMinutes: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property growTimeoutInMinutes: The scale-out timeout period.

Unit: minutes. Default value: 20

---

imageId^Optional

public readonly imageId: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property imageId: The ID of the image.

If you set both Queues.N.QueueImageId and ImageId, Queues.N.QueueImageId prevails. If you set Queues.N.QueueImageId or ImageId, the parameter that you set takes effect. If you leave both Queues.N.QueueImageId and ImageId empty, the image that was specified when you created the cluster or the last time when you scaled out the cluster is used by default.

---

maxNodesInCluster^Optional

public readonly maxNodesInCluster: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property maxNodesInCluster: The maximum number of compute nodes that can be added in the cluster.

Default value: 100

---

queues^Optional

public readonly queues: IResolvable | IResolvable | QueuesProperty[];

• Type: @alicloud/ros-cdk-core.IResolvable | @alicloud/ros-cdk-core.IResolvable | QueuesProperty[]

Property queues:.

---

shrinkIdleTimes^Optional

public readonly shrinkIdleTimes: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property shrinkIdleTimes: The number of consecutive times that a compute node is idle during the resource scale-in check.

Default value: 3

---

shrinkIntervalInMinutes^Optional

public readonly shrinkIntervalInMinutes: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property shrinkIntervalInMinutes: SThe interval between two consecutive rounds of scale-in.

Unit: minutes. Default value: 2

---

spotPriceLimit^Optional

public readonly spotPriceLimit: number | IResolvable;

• Type: number | @alicloud/ros-cdk-core.IResolvable

Property spotPriceLimit: The maximum hourly price of the compute nodes.

The value can be accurate to three decimal places. The parameter takes effect only when SpotStrategy is set to SpotWithPriceLimit.

---

spotStrategy^Optional

public readonly spotStrategy: string | IResolvable;

• Type: string | @alicloud/ros-cdk-core.IResolvable

Property spotStrategy: The preemption policy of the compute nodes.

Valid values: NoSpot: The compute nodes are pay-as-you-go instances. SpotWithPriceLimit: The compute nodes are preemptible instances that have a user-defined maximum hourly price. SpotAsPriceGo: The compute nodes are preemptible instances for which the market price at the time of purchase is used as the bid price. Default value: NoSpot
