CloudFormationStackNotificationCheck

class aws_cdk.aws_config.CloudFormationStackNotificationCheck(scope, id, *, topics=None, config_rule_name=None, description=None, evaluation_modes=None, input_parameters=None, maximum_execution_frequency=None, rule_scope=None)

Bases: ManagedRule

Checks whether your CloudFormation stacks are sending event notifications to a SNS topic.

Optionally checks whether specified SNS topics are used.

See:

https://docs.aws.amazon.com/config/latest/developerguide/cloudformation-stack-notification-check.html

Resource:

AWS::Config::ConfigRule

ExampleMetadata:

infused

Example:

# topics to which CloudFormation stacks may send event notifications
topic1 = sns.Topic(self, "AllowedTopic1")
topic2 = sns.Topic(self, "AllowedTopic2")

# non-compliant if CloudFormation stack does not send notifications to 'topic1' or 'topic2'
config.CloudFormationStackNotificationCheck(self, "NotificationCheck",
    topics=[topic1, topic2]
)
Parameters:

  • scope (Construct)

  • id (str)

  • topics (Optional[Sequence[ITopic]]) – A list of allowed topics. At most 5 topics. Default: - No topics.

  • config_rule_name (Optional[str]) – A name for the AWS Config rule. Default: - CloudFormation generated name

  • description (Optional[str]) – A description about this AWS Config rule. Default: - No description

  • evaluation_modes (Optional[EvaluationMode]) – The modes the AWS Config rule can be evaluated in. The valid values are distinct objects. Default: - Detective evaluation mode only

  • input_parameters (Optional[Mapping[str, Any]]) – Input parameter values that are passed to the AWS Config rule. Default: - No input parameters

  • maximum_execution_frequency (Optional[MaximumExecutionFrequency]) – The maximum frequency at which the AWS Config rule runs evaluations. Default: MaximumExecutionFrequency.TWENTY_FOUR_HOURS

  • rule_scope (Optional[RuleScope]) – Defines which resources trigger an evaluation for an AWS Config rule. Default: - evaluations for the rule are triggered when any resource in the recording group changes.

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

on_compliance_change(id, *, target=None, cross_stack_scope=None, description=None, event_pattern=None, rule_name=None)

Defines an EventBridge event rule which triggers for rule compliance events.

Parameters:

  • id (str)

  • target (Optional[IRuleTarget]) – The target to register for the event. Default: - No target is added to the rule. Use addTarget() to add a target.

  • cross_stack_scope (Optional[Construct]) – The scope to use if the source of the rule and its target are in different Stacks (but in the same account & region). This helps dealing with cycles that often arise in these situations. Default: - none (the main scope will be used, even for cross-stack Events)

  • description (Optional[str]) – A description of the rule’s purpose. Default: - No description

  • event_pattern (Union[EventPattern, Dict[str, Any], None]) – Additional restrictions for the event to route to the specified target. The method that generates the rule probably imposes some type of event filtering. The filtering implied by what you pass here is added on top of that filtering. Default: - No additional filtering based on an event pattern.

  • rule_name (Optional[str]) – A name for the rule. Default: AWS CloudFormation generates a unique physical ID.

Return type:

Rule

on_event(id, *, target=None, cross_stack_scope=None, description=None, event_pattern=None, rule_name=None)

Defines an EventBridge event rule which triggers for rule events.

Use rule.addEventPattern(pattern) to specify a filter.

Parameters:

  • id (str)

  • target (Optional[IRuleTarget]) – The target to register for the event. Default: - No target is added to the rule. Use addTarget() to add a target.

  • cross_stack_scope (Optional[Construct]) – The scope to use if the source of the rule and its target are in different Stacks (but in the same account & region). This helps dealing with cycles that often arise in these situations. Default: - none (the main scope will be used, even for cross-stack Events)

  • description (Optional[str]) – A description of the rule’s purpose. Default: - No description

  • event_pattern (Union[EventPattern, Dict[str, Any], None]) – Additional restrictions for the event to route to the specified target. The method that generates the rule probably imposes some type of event filtering. The filtering implied by what you pass here is added on top of that filtering. Default: - No additional filtering based on an event pattern.

  • rule_name (Optional[str]) – A name for the rule. Default: AWS CloudFormation generates a unique physical ID.

Return type:

Rule

on_re_evaluation_status(id, *, target=None, cross_stack_scope=None, description=None, event_pattern=None, rule_name=None)

Defines an EventBridge event rule which triggers for rule re-evaluation status events.

Parameters:

  • id (str)

  • target (Optional[IRuleTarget]) – The target to register for the event. Default: - No target is added to the rule. Use addTarget() to add a target.

  • cross_stack_scope (Optional[Construct]) – The scope to use if the source of the rule and its target are in different Stacks (but in the same account & region). This helps dealing with cycles that often arise in these situations. Default: - none (the main scope will be used, even for cross-stack Events)

  • description (Optional[str]) – A description of the rule’s purpose. Default: - No description

  • event_pattern (Union[EventPattern, Dict[str, Any], None]) – Additional restrictions for the event to route to the specified target. The method that generates the rule probably imposes some type of event filtering. The filtering implied by what you pass here is added on top of that filtering. Default: - No additional filtering based on an event pattern.

  • rule_name (Optional[str]) – A name for the rule. Default: AWS CloudFormation generates a unique physical ID.

Return type:

Rule

to_string()

Returns a string representation of this construct.

Return type:

str

Attributes

PROPERTY_INJECTION_ID = 'aws-cdk-lib.aws-config.CloudFormationStackNotificationCheck'
config_rule_arn

The arn of the rule.

Attribute:

true

config_rule_compliance_type

The compliance status of the rule.

Attribute:

true

config_rule_id

The id of the rule.

Attribute:

true

config_rule_name

The name of the rule.

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_config_rule_name(scope, id, config_rule_name)

Imports an existing rule.

Parameters:

  • scope (Construct)

  • id (str)

  • config_rule_name (str) – the name of the rule.

Return type:

IRule

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
