Implements IConstruct, IDependable, IResource, IAutoScalingConfiguration

The App Runner Auto Scaling Configuration.

Example

const autoScalingConfiguration = new apprunner.AutoScalingConfiguration(this, 'AutoScalingConfiguration', {
  autoScalingConfigurationName: 'MyAutoScalingConfiguration',
  maxConcurrency: 150,
  maxSize: 20,
  minSize: 5,
});

new apprunner.Service(this, 'DemoService', {
  source: apprunner.Source.fromEcrPublic({
    imageConfiguration: { port: 8000 },
    imageIdentifier: 'public.ecr.aws/aws-containers/hello-app-runner:latest',
  }),
  autoScalingConfiguration,
});

Initializer

new AutoScalingConfiguration(scope: Construct, id: string, props?: AutoScalingConfigurationProps)

Parameters

Construct Props

NameTypeDescription
autoScalingConfigurationName?🔹stringThe name for the Auto Scaling Configuration.
maxConcurrency?🔹numberThe maximum number of concurrent requests that an instance processes.
maxSize?🔹numberThe maximum number of instances that a service scales up to.
minSize?🔹numberThe minimum number of instances that App Runner provisions for a service.

autoScalingConfigurationName?🔹

Type: string (optional, default: a name generated by CloudFormation)

The name for the Auto Scaling Configuration.

maxConcurrency?🔹

Type: number (optional, default: 100)

The maximum number of concurrent requests that an instance processes.

If the number of concurrent requests exceeds this limit, App Runner scales the service up.

Must be between 1 and 200.

maxSize?🔹

Type: number (optional, default: 25)

The maximum number of instances that a service scales up to.

At most maxSize instances actively serve traffic for your service.

Must be between 1 and 25.

minSize?🔹

Type: number (optional, default: 1)

The minimum number of instances that App Runner provisions for a service.

The service always has at least minSize provisioned instances.

Must be between 1 and 25.

Properties

NameTypeDescription
autoScalingConfigurationArn🔹stringThe ARN of the Auto Scaling Configuration.
autoScalingConfigurationName🔹stringThe name of the Auto Scaling Configuration.
autoScalingConfigurationRevision🔹numberThe revision of the Auto Scaling Configuration.
env🔹ResourceEnvironmentThe environment this resource belongs to.
node🔹NodeThe tree node.
stack🔹StackThe stack in which this resource is defined.

autoScalingConfigurationArn🔹

Type: string

The ARN of the Auto Scaling Configuration.

autoScalingConfigurationName🔹

Type: string

The name of the Auto Scaling Configuration.

autoScalingConfigurationRevision🔹

Type: number

The revision of the Auto Scaling Configuration.

env🔹

Type: ResourceEnvironment

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.

node🔹

Type: Node

The tree node.

stack🔹

Type: Stack

The stack in which this resource is defined.

Methods

NameDescription
applyRemovalPolicy(policy)🔹Apply the given removal policy to this resource.
toString()🔹Returns a string representation of this construct.
static fromArn(scope, id, autoScalingConfigurationArn)🔹Imports an App Runner Auto Scaling Configuration from its ARN.
static fromAutoScalingConfigurationAttributes(scope, id, attrs)🔹Imports an App Runner Auto Scaling Configuration from attributes.

applyRemovalPolicy(policy)🔹

public applyRemovalPolicy(policy: RemovalPolicy): void

Parameters

Apply the given removal policy to this resource.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

toString()🔹

public toString(): string

Returns

  • string

Returns a string representation of this construct.

static fromArn(scope, id, autoScalingConfigurationArn)🔹

public static fromArn(scope: Construct, id: string, autoScalingConfigurationArn: string): IAutoScalingConfiguration

Parameters

  • scope Construct
  • id string
  • autoScalingConfigurationArn string

Returns

Imports an App Runner Auto Scaling Configuration from its ARN.

static fromAutoScalingConfigurationAttributes(scope, id, attrs)🔹

public static fromAutoScalingConfigurationAttributes(scope: Construct, id: string, attrs: AutoScalingConfigurationAttributes): IAutoScalingConfiguration

Parameters

Returns

Imports an App Runner Auto Scaling Configuration from attributes.
