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.

Methods

toString

public java.lang.String toString()

Returns a string representation of this construct.

synthesize

public void synthesize(ISynthesisSession session)

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

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

The synthesis session.

addCondition

public void addCondition(RosCondition condition)

condition^Required

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

addCount

public void addCount(java.lang.Number OR IResolvable count)

count^Required

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

addDependency

public void addDependency(Resource resource)

resource^Required

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

addResourceDesc

public void addResourceDesc(java.lang.String desc)

desc^Required

• Type: java.lang.String

applyRemovalPolicy

public void applyRemovalPolicy(RemovalPolicy policy)

policy^Required

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

fetchCondition

public RosCondition fetchCondition()

fetchDependency

public java.util.List<java.lang.String> fetchDependency()

fetchResourceDesc

public java.lang.String fetchResourceDesc()

getAtt

public IResolvable getAtt(java.lang.String name)

name^Required

• Type: java.lang.String

setMetadata

public void setMetadata(java.lang.String key, java.lang.Object value)

key^Required

• Type: java.lang.String

value^Required

• Type: java.lang.Object

Static Functions

isConstruct

import com.aliyun.ros.cdk.sae.ApplicationScalingRule;
ApplicationScalingRule.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

x^Required

• Type: java.lang.Object

Properties

node^Required

public ConstructNode getNode();

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

The construct tree node associated with this construct.

env^Required

public IResourceEnvironment getEnv();

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

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

ref^Required

public java.lang.String getRef();

• Type: java.lang.String

stack^Required

public Stack getStack();

• Type: com.aliyun.ros.cdk.core.Stack

The stack in which this resource is defined.

resource^Optional

public RosResource getResource();

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

attrScalingRuleName^Required

public java.lang.Object getAttrScalingRuleName();

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

Attribute ScalingRuleName: The name of the scaling rule.

props^Required

public ApplicationScalingRuleProps getProps();

• Type: ApplicationScalingRuleProps
