Implements IConstruct, IConstruct, IDependable, IInspectable

A CloudFormation AWS::WAFv2::RuleGroup.

This is the latest version of AWS WAF , named AWS WAF V2, released in November, 2019. For information, including how to migrate your AWS WAF resources from the prior release, see the AWS WAF Developer Guide .

Use an RuleGroup to define a collection of rules for inspecting and controlling web requests. You use a rule group in an WebACL by providing its Amazon Resource Name (ARN) to the rule statement RuleGroupReferenceStatement , when you add rules to the web ACL.

When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

capacity

Type: number

The web ACL capacity units (WCUs) required for this rule group.

When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit.

AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

scope

Type: string

Specifies whether this is for an Amazon CloudFront distribution or for a regional application.

A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AWS AppSync GraphQL API, an Amazon Cognito user pool, or an AWS App Runner service. Valid Values are CLOUDFRONT and REGIONAL .

For CLOUDFRONT , you must create your WAFv2 resources in the US East (N. Virginia) Region, us-east-1 .

visibilityConfig

Type: IResolvable | VisibilityConfigProperty

Defines and enables Amazon CloudWatch metrics and web request sample collection.

availableLabels?

Type: IResolvable | IResolvable | LabelSummaryProperty[] (optional)

The labels that one or more rules in this rule group add to matching web requests.

These labels are defined in the RuleLabels for a Rule .

consumedLabels?

Type: IResolvable | IResolvable | LabelSummaryProperty[] (optional)

The labels that one or more rules in this rule group match against in label match statements.

These labels are defined in a LabelMatchStatement specification, in the Statement definition of a rule.

customResponseBodies?

Type: IResolvable | { [string]: IResolvable | CustomResponseBodyProperty } (optional)

A map of custom response keys and content bodies.

When you create a rule with a block action, you can send a custom response to the web request. You define these for the rule group, and then use them in the rules that you define in the rule group.

For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .

For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .

description?

Type: string (optional)

A description of the rule group that helps with identification.

name?

Type: string (optional)

The name of the rule group.

You cannot change the name of a rule group after you create it.

rules?

Type: IResolvable | IResolvable | RuleProperty[] (optional)

The rule statements used to identify the web requests that you want to allow, block, or count.

Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

tags?

Type: CfnTag[] (optional)

Key:value pairs associated with an AWS resource.

The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

To modify tags on existing resources, use the AWS WAF APIs or command line interface. With AWS CloudFormation , you can only add tags to AWS WAF resources during resource creation.

attrArn

Type: string

The Amazon Resource Name (ARN) of the rule group.

attrId

Type: string

The ID of the rule group.

attrLabelNamespace

Type: string

The label namespace prefix for this rule group.

All labels added by rules in this rule group have this prefix.

The syntax for the label namespace prefix for a rule group is the following: awswaf:<account ID>:rule group:<rule group name>:

When a rule with a label matches a web request, AWS WAF adds the fully qualified label to the request. A fully qualified label is made up of the label namespace from the rule group or web ACL where the rule is defined and the label from the rule, separated by a colon.

capacity

Type: number

The web ACL capacity units (WCUs) required for this rule group.

When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, AWS WAF enforces this limit.

AWS WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. AWS WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

cfnOptions

Type: ICfnResourceOptions

Options for this resource, such as condition, update policy etc.

cfnProperties

Type: { [string]: any }

cfnResourceType

Type: string

AWS resource type.

creationStack

Type: string[]

logicalId

Type: string

The logical ID for this CloudFormation stack element.

The logical ID of the element is calculated from the path of the resource node in the construct tree.

To override this value, use overrideLogicalId(newLogicalId).

node

Type: ConstructNode

The construct tree node associated with this construct.

ref

Type: string

Return a string that will be resolved to a CloudFormation { Ref } for this element.

If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through Lazy.any({ produce: resource.ref }).

scope

Type: string

Specifies whether this is for an Amazon CloudFront distribution or for a regional application.

A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, an AWS AppSync GraphQL API, an Amazon Cognito user pool, or an AWS App Runner service. Valid Values are CLOUDFRONT and REGIONAL .

For CLOUDFRONT , you must create your WAFv2 resources in the US East (N. Virginia) Region, us-east-1 .

stack

Type: Stack

The stack in which this element is defined.

CfnElements must be defined within a stack scope (directly or indirectly).

tags

Type: TagManager

Key:value pairs associated with an AWS resource.

The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

To modify tags on existing resources, use the AWS WAF APIs or command line interface. With AWS CloudFormation , you can only add tags to AWS WAF resources during resource creation.

visibilityConfig

Type: IResolvable | VisibilityConfigProperty

Defines and enables Amazon CloudWatch metrics and web request sample collection.

availableLabels?

Type: IResolvable | IResolvable | LabelSummaryProperty[] (optional)

The labels that one or more rules in this rule group add to matching web requests.

These labels are defined in the RuleLabels for a Rule .

consumedLabels?

Type: IResolvable | IResolvable | LabelSummaryProperty[] (optional)

The labels that one or more rules in this rule group match against in label match statements.

These labels are defined in a LabelMatchStatement specification, in the Statement definition of a rule.

customResponseBodies?

Type: IResolvable | { [string]: IResolvable | CustomResponseBodyProperty } (optional)

A map of custom response keys and content bodies.

When you create a rule with a block action, you can send a custom response to the web request. You define these for the rule group, and then use them in the rules that you define in the rule group.

For information about customizing web requests and responses, see Customizing web requests and responses in AWS WAF in the AWS WAF Developer Guide .

For information about the limits on count and size for custom request and response settings, see AWS WAF quotas in the AWS WAF Developer Guide .

description?

Type: string (optional)

A description of the rule group that helps with identification.

name?

Type: string (optional)

The name of the rule group.

You cannot change the name of a rule group after you create it.

rules?

Type: IResolvable | IResolvable | RuleProperty[] (optional)

The rule statements used to identify the web requests that you want to allow, block, or count.

Each rule includes one top-level statement that AWS WAF uses to identify matching web requests, and parameters that govern how AWS WAF handles them.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

  • path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

addDependsOn(target)

public addDependsOn(target: CfnResource): void

Parameters

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.

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

  • key string
  • value any

Add a value to the CloudFormation Resource Metadata.

See also: [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.](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.)

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

  • path string — - The path of the property, you can use dot notation to override values in complex types.
  • value any — - The 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,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

  • propertyPath string — The path to the property.

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

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

  • propertyPath string — The path of the property.
  • value any — The value.

Adds an override to a resource property.

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

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

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).

getAtt(attributeName)

public getAtt(attributeName: string): Reference

Parameters

  • attributeName string — The name of the attribute.

Returns

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.

getMetadata(key)

public getMetadata(key: string): any

Parameters

  • key string

Returns

  • any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [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.](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.)

inspect(inspector)

public inspect(inspector: TreeInspector): void

Parameters

  • inspector TreeInspector — - tree inspector to collect and process attributes.

Examines the CloudFormation resource and discloses attributes.

overrideLogicalId(newLogicalId)

public overrideLogicalId(newLogicalId: string): void

Parameters

  • newLogicalId string — The new logical ID to use for this stack element.

Overrides the auto-generated logical ID with a specific ID.

toString()

public toString(): string

Returns

  • string

Returns a string representation of this construct.

protected renderProperties(props)

protected renderProperties(props: { [string]: any }): { [string]: any }

Parameters

  • props { [string]: any }

Returns

  • { [string]: any }
