RosScalingGroup

This class is a base encapsulation around the ROS resource type ALIYUN::ESS::ScalingGroup, which is used to create a scaling group.

A scaling group can be a group of Elastic Compute Service (ECS) instances that are dynamically scaled based on the configured scenario. A scaling group does not immediately take effect after it is created. You must use ALIYUN::ESS::ScalingGroupEnable to enable the scaling group to trigger scaling activities based on scaling rules.

---

toString

public toString(): string

Returns a string representation of this construct.

synthesize

public synthesize(session: ISynthesisSession): void

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: @alicloud/ros-cdk-core.ISynthesisSession

The synthesis session.

---

overrideLogicalId

public overrideLogicalId(newLogicalId: string): void

Overrides the auto-generated logical ID with a specific ID.

newLogicalId^Required

• Type: string

The new logical ID to use for this stack element.

---

addCondition

public addCondition(con: RosCondition): void

con^Required

• Type: @alicloud/ros-cdk-core.RosCondition

---

addCount

public addCount(count: number | IResolvable): void

count^Required

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

---

addDeletionOverride

public addDeletionOverride(path: string): void

Syntactic sugar for addOverride(path, undefined).

path^Required

• Type: string

The path of the value to delete.

---

addDependsOn

public addDependsOn(target: RosResource): void

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

target^Required

• Type: @alicloud/ros-cdk-core.RosResource

---

addDesc

public addDesc(desc: string): void

desc^Required

• Type: string

---

addMetaData

public addMetaData(key: string, value: any): void

key^Required

• Type: string

---

value^Required

• Type: any

---

addOverride

public addOverride(path: string, value: any): void

Adds an override to the synthesized ROS resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

For example,

addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute'])
addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE')

would add the overrides

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

path^Required

• Type: string

The path of the property, you can use dot notation to override values in complex types.

Any intermdediate keys will be created as needed.

---

value^Required

• Type: any

The value.

Could be primitive or complex.

---

addPropertyDeletionOverride

public addPropertyDeletionOverride(propertyPath: string): void

Adds an override that deletes the value of a property from the resource definition.

propertyPath^Required

• Type: string

The path to the property.

---

addPropertyOverride

public addPropertyOverride(propertyPath: string, value: any): void

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

• Type: string

The path of the property.

---

value^Required

• Type: any

The value.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

attributeName^Required

• Type: string

The name of the attribute.

---
