AutoScalingConfiguration

class aws_cdk.aws_apprunner_alpha.AutoScalingConfiguration(scope, id, *, auto_scaling_configuration_name=None, max_concurrency=None, max_size=None, min_size=None)

Bases: Resource

(experimental) The App Runner Auto Scaling Configuration.

Stability:

experimental

Resource:

AWS::AppRunner::AutoScalingConfiguration

ExampleMetadata:

infused

Example:

auto_scaling_configuration = apprunner.AutoScalingConfiguration(self, "AutoScalingConfiguration",
    auto_scaling_configuration_name="MyAutoScalingConfiguration",
    max_concurrency=150,
    max_size=20,
    min_size=5
)

apprunner.Service(self, "DemoService",
    source=apprunner.Source.from_ecr_public(
        image_configuration=apprunner.ImageConfiguration(port=8000),
        image_identifier="public.ecr.aws/aws-containers/hello-app-runner:latest"
    ),
    auto_scaling_configuration=auto_scaling_configuration
)
Parameters:
  • scope (Construct) –

  • id (str) –

  • auto_scaling_configuration_name (Optional[str]) – (experimental) The name for the Auto Scaling Configuration. Default: - a name generated by CloudFormation

  • max_concurrency (Union[int, float, None]) – (experimental) 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. Default: 100

  • max_size (Union[int, float, None]) – (experimental) 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. Default: 25

  • min_size (Union[int, float, None]) – (experimental) 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. Default: 1

Methods

apply_removal_policy(policy)

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).

Parameters:

policy (RemovalPolicy) –

Return type:

None

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

auto_scaling_configuration_arn

(experimental) The ARN of the Auto Scaling Configuration.

Stability:

experimental

Attribute:

true

auto_scaling_configuration_name

(experimental) The name of the Auto Scaling Configuration.

Stability:

experimental

Attribute:

true

auto_scaling_configuration_revision

(experimental) The revision of the Auto Scaling Configuration.

Stability:

experimental

Attribute:

true

env

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

The tree node.

stack

The stack in which this resource is defined.

Static Methods

classmethod from_arn(scope, id, auto_scaling_configuration_arn)

(experimental) Imports an App Runner Auto Scaling Configuration from its ARN.

Parameters:
  • scope (Construct) –

  • id (str) –

  • auto_scaling_configuration_arn (str) –

Stability:

experimental

Return type:

IAutoScalingConfiguration

classmethod from_auto_scaling_configuration_attributes(scope, id, *, auto_scaling_configuration_name, auto_scaling_configuration_revision)

(experimental) Imports an App Runner Auto Scaling Configuration from attributes.

Parameters:
  • scope (Construct) –

  • id (str) –

  • auto_scaling_configuration_name (str) – (experimental) The name of the Auto Scaling Configuration.

  • auto_scaling_configuration_revision (Union[int, float]) – (experimental) The revision of the Auto Scaling Configuration.

Stability:

experimental

Return type:

IAutoScalingConfiguration

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:

x (Any) – Any object.

Return type:

bool

Returns:

true if x is an object created from a class which extends Construct.

classmethod is_owned_resource(construct)

Returns true if the construct was created by CDK, and false otherwise.

Parameters:

construct (IConstruct) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
