Resource

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

Bases: Construct

A construct which represents an AWS resource.

ExampleMetadata:: infused

Example:

import aws_cdk.core as cdk


class MyConstruct(cdk.Resourcecdk.ITaggable):

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

        cdk.CfnResource(self, "Resource",
            type="Whatever::The::Type",
            properties={
                # ...
                "Tags": self.tags.rendered_tags
            }
        )

Parameters:

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

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

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 construct tree node associated with this construct.

stack: The stack in which this resource is defined.

Static Methods

classmethod is_construct(x)

Return whether the given object is a Construct.

Parameters:

x (Any) –

Return type:

bool

classmethod is_resource(construct)

Check whether the given construct is a Resource.

Parameters:

construct (IConstruct) –

Return type:

bool
