CfnWebACL

class aws_cdk.aws_wafregional.CfnWebACL(scope, id, *, default_action, metric_name, name, rules=None)

Bases: CfnResource

This is AWS WAF Classic documentation.

For more information, see AWS WAF Classic in the developer guide. .. epigraph:
*For the latest version of AWS WAF* , use the AWS WAF V2 API and see the `AWS WAF Developer Guide <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html>`_ . With the latest version, AWS WAF has a single set of endpoints for regional and global use.
Contains the Rules that identify the requests that you want to allow, block, or count. In a WebACL , you also specify a default action ( ALLOW or BLOCK ), and the action for each Rule that you add to a WebACL , for example, block requests from specified IP addresses or block requests from specified referrers. If you add more than one Rule to a WebACL , a request needs to match only one of the specifications to be allowed, blocked, or counted.

To identify the requests that you want AWS WAF to filter, you associate the WebACL with an API Gateway API or an Application Load Balancer.

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_dependency(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_depends_on(target)

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

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

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.

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"
      ...
    },
  ]
  ...
}

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:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermediate 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). 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:

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 resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

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.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

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)

Examines the CloudFormation resource and discloses attributes.

Parameters:: inspector (TreeInspector) – tree inspector to collect and process attributes.
Return type:: None

obtain_dependencies()

Retrieves an array of resources this resource depends on.

This assembles dependencies on resources across stacks (including nested stacks) automatically.

Return type:: List[Union[Stack, CfnResource]]

obtain_resource_dependencies()

Return type:: str
Returns:: a string representation of this resource

Attributes

CFN_RESOURCE_TYPE_NAME = 'AWS::WAFRegional::WebACL'

attr_id

Id

Type:: cloudformationAttribute

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

cfn_resource_type: AWS resource type.

creation_stack

return:

the stack trace of the point where this Resource was created from, sourced from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most node +internal+ entries filtered.

default_action: The action to perform if none of the Rules contained in the WebACL match.

logical_id

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).

Returns:

the logical ID as a stringified token. This value will only get resolved during synthesis.

metric_name: A name for the metrics for this WebACL .

name: A friendly name or description of the WebACL .

node: The tree node.

ref

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 }).

rules: An array that contains the action for each Rule in a WebACL , the priority of the Rule , and the ID of the Rule .

stack

The stack in which this element is defined.

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

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

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

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

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.

ActionProperty

class CfnWebACL.ActionProperty(*, type)

Bases: object

Specifies the action AWS WAF takes when a web request matches or doesn’t match all rule conditions.

Parameters:: type (str) – For actions that are associated with a rule, the action that AWS WAF takes when a web request matches all conditions in a rule. For the default action of a web access control list (ACL), the action that AWS WAF takes when a web request doesn’t match all conditions in any rule. Valid settings include the following: - ALLOW : AWS WAF allows requests - BLOCK : AWS WAF blocks requests - COUNT : AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can’t specify COUNT for the default action for a WebACL.
See:: http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-wafregional-webacl-action.html

type

For actions that are associated with a rule, the action that AWS WAF takes when a web request matches all conditions in a rule.

For the default action of a web access control list (ACL), the action that AWS WAF takes when a web request doesn’t match all conditions in any rule.

Valid settings include the following:

ALLOW : AWS WAF allows requests
BLOCK : AWS WAF blocks requests
COUNT : AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can’t specify COUNT for the default action for a WebACL.

RuleProperty

class CfnWebACL.RuleProperty(*, action, priority, rule_id)

Bases: object

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 .

Parameters:

action (Union[IResolvable, ActionProperty, Dict[str, Any]]) – The action that AWS WAF takes when a web request matches all conditions in the rule, such as allow, block, or count the request.
priority (Union[int, float]) – The order in which AWS WAF evaluates the rules in a web ACL. AWS WAF evaluates rules with a lower value before rules with a higher value. The value must be a unique integer. If you have multiple rules in a web ACL, the priority numbers do not need to be consecutive.
rule_id (str) – The ID of an AWS WAF Regional rule to associate with a web ACL.
