class aws_cdk.Resource(scope, id, *, account=None, environment_from_arn=None, physical_name=None, region=None)

Bases: Construct

A construct which represents an AWS resource.




class MyConstruct(Resource):

    def __init__(self, scope, id):
        super().__init__(scope, id)

        CfnResource(self, "Resource",
                # ...
                "Tags": self.tags.rendered_tags
  • scope (Construct) –

  • id (str) –

  • account (Optional[str]) – The AWS account ID this resource belongs to. Default: - the resource is in the same account as the stack it belongs to

  • environment_from_arn (Optional[str]) – ARN to deduce region and account from. The ARN is parsed and the account and region are taken from the ARN. This should be used for imported resources. Cannot be supplied together with either account or region. Default: - take environment from account, region parameters, or use Stack environment.

  • physical_name (Optional[str]) – The value passed in by users to the physical name prop of the resource. - undefined implies that a physical name will be allocated by CloudFormation during deployment. - a concrete value implies a specific physical name - PhysicalName.GENERATE_IF_NEEDED is a marker that indicates that a physical will only be generated by the CDK if it is needed for cross-environment references. Otherwise, it will be allocated by CloudFormation. Default: - The physical name will be allocated by CloudFormation at deployment time

  • region (Optional[str]) – The AWS region this resource belongs to. Default: - the resource is in the same region as the stack it belongs to



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).

Return type:



Returns a string representation of this construct.

Return type:




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.


The tree node.


The stack in which this resource is defined.

Static Methods

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.


x (Any) – Any object.

Return type:



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.
