scope^Required

• Type: com.aliyun.ros.cdk.core.Construct

---

id^Required

• Type: java.lang.String

---

enableResourcePropertyConstraint^Optional

• Type: java.lang.Boolean

---

appId^Required

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property appId: The ID of the application.

---

scalingRuleName^Required

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleName: The name of the auto scaling policy.

The name must start with a lowercase letter, and can contain lowercase letters, digits, and hyphens (-).The name must be 1 to 32 characters in length.

---

scalingRuleType^Required

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleType: The type of the auto scaling policy.

Valid values: timer: Timed scaling. metric: Custom metric scaling.mix: mix scaling

---

minReadyInstanceRatio^Optional

• Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

Property minReadyInstanceRatio: The minimum percentage of surviving instances.

The value description is as follows:-1: Initialization value, indicating that the percentage is not used.0~100: The unit is a percentage, rounded up. For example, if it is set to 50%, if there are currently 5 instances, the minimum number of surviving instances is 3.

---

minReadyInstances^Optional

• Type: java.lang.Number OR com.aliyun.ros.cdk.core.IResolvable

Property minReadyInstances: Minimum number of surviving instances.

The value is as follows:If set to 0, the application will be interrupted during the upgrade process.If set to -1, the minimum number of surviving instances will use the system recommended value, which is 25% of the existing number of instances. If there are currently 5 instances, 5×25%=1.25, after rounding up, the minimum number of surviving instances is 2.

---

scalingRuleEnable^Optional

• Type: java.lang.Boolean OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleEnable: Whether to enable the scaling rule.

---

scalingRuleMetric^Optional

• Type: com.aliyun.ros.cdk.core.IResolvable OR ScalingRuleMetricProperty

Property scalingRuleMetric: Configuration of monitoring indicator elasticity policy.

This parameter is required when you select monitoring indicator elasticity policy setting.

---

scalingRuleTimer^Optional

• Type: com.aliyun.ros.cdk.core.IResolvable OR ScalingRuleTimerProperty

Property scalingRuleTimer: The configuration of the timer scaling policy.
