TopicPolicy

class aws_cdk.aws_sns.TopicPolicy(scope, id, *, topics, policy_document=None)

Bases: Resource

The policy for an SNS Topic.

Policies define the operations that are allowed on this resource.

You almost never need to define this construct directly.

All AWS resources that support resource policies have a method called addToResourcePolicy(), which will automatically create a new resource policy if one doesn’t exist yet, otherwise it will add to the existing policy.

Prefer to use addToResourcePolicy() instead.

ExampleMetadata:

infused

Example:

topic = sns.Topic(self, "Topic")
topic_policy = sns.TopicPolicy(self, "TopicPolicy",
    topics=[topic]
)

topic_policy.document.add_statements(iam.PolicyStatement(
    actions=["sns:Subscribe"],
    principals=[iam.AnyPrincipal()],
    resources=[topic.topic_arn]
))

Parameters:

• scope (Construct) –

• id (str) –

• topics (Sequence[ITopic]) – The set of topics this policy applies to.

• policy_document (Optional[PolicyDocument]) – IAM policy document to apply to topic(s). Default: empty policy document

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

document

The IAM policy document for this policy.

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)

Parameters:

x (Any) –

Return type:

classmethod is_resource(construct)

Check whether the given construct is a Resource.
