aws-cdk-lib.aws_wafv2.CfnIPSet

CfnIPSet L1 construct

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 IPSet to identify web requests that originate from specific IP addresses or ranges of IP addresses. For example, if you're receiving a lot of requests from a ranges of IP addresses, you can configure AWS WAF to block them using an IP set that lists those IP addresses.

You use an IP set by providing its Amazon Resource Name (ARN) to the rule statement IPSetReferenceStatement , when you add a rule to a rule group or web ACL.

addressesstring[]addressestyping.List[str]addressesList<String>Addressesstring[]Addresses*[]*stringrequired#

Contains an array of strings that specifies zero or more IP addresses or blocks of IP addresses that you want AWS WAF to inspect for in incoming requests.

notes

All addresses must be specified using Classless Inter-Domain Routing (CIDR) notation. AWS WAF supports all IPv4 and IPv6 CIDR ranges except for /0 .

Example address strings:

• For requests that originated from the IP address 192.0.2.44, specify 192.0.2.44/32 .
• For requests that originated from IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24 .
• For requests that originated from the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128 .
• For requests that originated from IP addresses 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64 .

For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .

Example JSON Addresses specifications:

• Empty array: "Addresses": []
• Array with one address: "Addresses": ["192.0.2.44/32"]
• Array with three addresses: "Addresses": ["192.0.2.44/32", "192.0.2.0/24", "192.0.0.0/16"]
• INVALID specification: "Addresses": [""] INVALID

Key:value pairs associated with an AWS resource.

notes

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.

Methods

addDeletionOverride(path: string): voiddef add_deletion_override(self, path: str) -> Nonepublic void addDeletionOverride(String path)public void AddDeletionOverride(string path)func AddDeletionOverride(Path *string)#

Syntactic sugar for `addOverride(path, undefined)`.

1 parameter

Parameters

• pathpathpathpathPath — The path of the value to delete.

addDependency(target: CfnResource): voiddef add_dependency(self, target: CfnResource) -> Nonepublic void addDependency(CfnResource target)public void AddDependency(CfnResource target)func AddDependency(Target CfnResource)deprecated#

Use `addResourceDependency` instead.

This method has been renamed to addResourceDependency to more clearly set it apart from construct.node.addDependency. See the documentation of that function for more details.

addDependsOn(target: CfnResource): voiddef add_depends_on(self, target: CfnResource) -> Nonepublic void addDependsOn(CfnResource target)public void AddDependsOn(CfnResource target)func AddDependsOn(Target CfnResource)deprecated#

Use `addResourceDependency` instead.

notes

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

This method has been renamed to addResourceDependency, which makes it more clear that this method operates at a different level from the construct-level construct.node.addDependency() mechanism.

addMetadata(key: string, value: any): voiddef add_metadata(self, key: str, value: Any) -> Nonepublic void addMetadata(String key, Object value)public void AddMetadata(string key, object value)func AddMetadata(Key *string, Value interface{})#

Add a value to the CloudFormation Resource Metadata.

addOverride(path: string, value: any): voiddef add_override(self, path: str, value: Any) -> Nonepublic void addOverride(String path, Object value)public void AddOverride(string path, object value)func AddOverride(Path *string, Value interface{})#

Adds an override to the synthesized CloudFormation resource.

notes · 2 parameters

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.

Parameters

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

addPropertyDeletionOverride(propertyPath: string): voiddef add_property_deletion_override(self, property_path: str) -> Nonepublic void addPropertyDeletionOverride(String propertyPath)public void AddPropertyDeletionOverride(string propertyPath)func AddPropertyDeletionOverride(PropertyPath *string)#

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

1 parameter

Parameters

• propertyPathproperty_pathpropertyPathpropertyPathPropertyPath — The path to the property.

addPropertyOverride(propertyPath: string, value: any): voiddef add_property_override(self, property_path: str, value: Any) -> Nonepublic void addPropertyOverride(String propertyPath, Object value)public void AddPropertyOverride(string propertyPath, object value)func AddPropertyOverride(PropertyPath *string, Value interface{})#

Adds an override to a resource property.

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

2 parameters

Parameters

• propertyPathproperty_pathpropertyPathpropertyPathPropertyPath — The path of the property.
• valuevaluevaluevalueValue — The value.

addResourceDependency(target: CfnResource, reason?: string): voiddef add_resource_dependency(self, target: CfnResource, reason: typing.Optional[str] = None) -> Nonepublic void addResourceDependency(CfnResource target, String reason)public void AddResourceDependency(CfnResource target, string? reason = null)func AddResourceDependency(Target CfnResource, Reason *string)#

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

notes

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

This method only adds dependencies between L1 resources. If you are looking for a generic construct-to-construct dependency mechanism that works for all constructs including L2s, use construct.node.addDependency instead.

applyCrossStackReferenceStrength(strength: ReferenceStrength): voiddef apply_cross_stack_reference_strength(self, strength: ReferenceStrength) -> Nonepublic void applyCrossStackReferenceStrength(ReferenceStrength strength)public void ApplyCrossStackReferenceStrength(ReferenceStrength strength)func ApplyCrossStackReferenceStrength(Strength ReferenceStrength)#

Sets the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified strength instead of the global default from the consuming stack's context.

1 parameter

Parameters

• strengthstrengthstrengthstrengthStrength — - The reference strength to use for this resource.

applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): voiddef apply_removal_policy(self, policy: typing.Optional[RemovalPolicy] = None, options: typing.Optional[RemovalPolicyOptions] = None) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)public void ApplyRemovalPolicy(RemovalPolicy? policy = null, RemovalPolicyOptions? options = null)func ApplyRemovalPolicy(Policy RemovalPolicy, Options RemovalPolicyOptions)#

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

notes

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). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

returns

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

isCfnIPSet(x: any): boolean@staticmethod def is_cfn_ip_set(x: Any) -> boolpublic static Boolean isCfnIPSet(Object x)public static bool IsCfnIPSet(object x)func IsCfnIPSet(X interface{}) *boolstatic#

Check whether the given object is a CfnResource.

isConstruct(x: any): boolean@staticmethod def is_construct(x: Any) -> boolpublic static Boolean isConstruct(Object x)public static bool IsConstruct(object x)func IsConstruct(X interface{}) *boolstatic#

Checks if `x` is a construct.

notes · 1 parameter · returns

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

• xxxxX — Any object.

Returns: true if x is an object created from a class which extends Construct.
