CfnRule

class aws_cdk.aws_wafregional.CfnRule(scope, id, *, metric_name, name, predicates=None)

Bases: aws_cdk.core.CfnResource

A CloudFormation AWS::WAFRegional::Rule.

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAF V2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

A combination of ByteMatchSet , IPSet , and/or SqlInjectionMatchSet objects that identify the web requests that you want to allow, block, or count. For example, you might create a Rule that includes the following predicates:

  • An IPSet that causes AWS WAF to search for web requests that originate from the IP address 192.0.2.44

  • A ByteMatchSet that causes AWS WAF to search for web requests for which the value of the User-Agent header is BadBot .

To match the settings in this Rule , a request must originate from 192.0.2.44 AND include a User-Agent header for which the value is BadBot .

ExampleMetadata

Example:

# The code below shows an example of how to instantiate this type.
# The values are placeholders you should change.
import aws_cdk.aws_wafregional as wafregional

cfn_rule = wafregional.CfnRule(self, "MyCfnRule",
    metric_name="metricName",
    name="name",

    # the properties below are optional
    predicates=[wafregional.CfnRule.PredicateProperty(
        data_id="dataId",
        negated=False,
        type="type"
    )]
)

Create a new AWS::WAFRegional::Rule.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • metric_name (str) – A name for the metrics for this Rule . The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can’t contain whitespace or metric names reserved for AWS WAF, including “All” and “Default_Action.” You can’t change MetricName after you create the Rule .

  • name (str) – The friendly name or description for the Rule . You can’t change the name of a Rule after you create it.

  • predicates (Union[IResolvable, Sequence[Union[IResolvable, PredicateProperty]], None]) – The Predicates object contains one Predicate element for each ByteMatchSet , IPSet , or SqlInjectionMatchSet object that you want to include in a Rule .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}
Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

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 (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

Any

inspect(inspector)

Examines the CloudFormation resource and discloses attributes.

Parameters

inspector (TreeInspector) –

  • tree inspector to collect and process attributes.

Return type

None

override_logical_id(new_logical_id)

Returns

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(construct)

PredicateProperty

class CfnRule.PredicateProperty(*, data_id, negated, type)

Bases: object

Specifies the ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , RegexMatchSet , GeoMatchSet , and SizeConstraintSet objects that you want to add to a Rule and, for each object, indicates whether you want to negate the settings, for example, requests that do NOT originate from the IP address 192.0.2.44.

Parameters
  • data_id (str) – A unique identifier for a predicate in a Rule , such as ByteMatchSetId or IPSetId . The ID is returned by the corresponding Create or List command.

  • negated (Union[bool, IResolvable]) – Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , RegexMatchSet , GeoMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow or block requests based on that IP address. Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , RegexMatchSet , GeoMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44 .

  • type (str) – The type of predicate in a Rule , such as ByteMatch or IPSet .
