NodeProxyAgentLayer

class aws_cdk.lambda_layer_node_proxy_agent.NodeProxyAgentLayer(scope, id)

Bases: LayerVersion

An AWS Lambda layer that includes the NPM dependency proxy-agent.

ExampleMetadata

infused

Example:

from aws_cdk.lambda_layer_node_proxy_agent import NodeProxyAgentLayer
import aws_cdk.aws_lambda as lambda_

# fn: lambda.Function

fn.add_layers(NodeProxyAgentLayer(self, "NodeProxyAgentLayer"))
Parameters

Methods

add_permission(id, *, account_id, organization_id=None)

Add permission for this layer version to specific entities.

Usage within the same account where the layer is defined is always allowed and does not require calling this method. Note that the principal that creates the Lambda function using the layer (for example, a CloudFormation changeset execution role) also needs to have the lambda:GetLayerVersion permission on the layer version.

Parameters
  • id (str) –

  • account_id (str) – The AWS Account id of the account that is authorized to use a Lambda Layer Version. The wild-card '*' can be used to grant access to “any” account (or any account in an organization when organizationId is specified).

  • organization_id (Optional[str]) – The ID of the AWS Organization to which the grant is restricted. Can only be specified if accountId is '*'

Return type

None

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

compatible_runtimes

The runtimes compatible with this Layer.

Return type

Optional[List[Runtime]]

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.

Return type

ResourceEnvironment

layer_version_arn

The ARN of the Lambda Layer version that this Layer defines.

Return type

str

node

The tree node.

Return type

Node

stack

The stack in which this resource is defined.

Return type

Stack

Static Methods

classmethod from_layer_version_arn(scope, id, layer_version_arn)

Imports a layer version by ARN.

Assumes it is compatible with all Lambda runtimes.

Parameters
  • scope (Construct) –

  • id (str) –

  • layer_version_arn (str) –

Return type

ILayerVersion

classmethod from_layer_version_attributes(scope, id, *, layer_version_arn, compatible_runtimes=None)

Imports a Layer that has been defined externally.

Parameters
  • scope (Construct) – the parent Construct that will use the imported layer.

  • id (str) – the id of the imported layer in the construct tree.

  • layer_version_arn (str) – The ARN of the LayerVersion.

  • compatible_runtimes (Optional[Sequence[Runtime]]) – The list of compatible runtimes with this Layer.

Return type

ILayerVersion

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
