See ‘aws help’ for descriptions of global parameters.

Synopsis

  create-regex-pattern-set
--name <value>
--scope <value>
[--description <value>]
--regular-expression-list <value>

[--generate-cli-skeleton <value>]

Options

--name (string)

The name of the set. You cannot change the name after you create the set.

--scope (string)

Specifies whether this is for an AWS CloudFront distribution or for a regional application. A regional application can be an Application Load Balancer (ALB), an API Gateway REST API, or an AppSync GraphQL API.

To work with CloudFront, you must also specify the Region US East (N. Virginia) as follows:

  • CLI - Specify the Region when you use the CloudFront scope: --scope=CLOUDFRONT --region=us-east-1 .

  • API and SDKs - For all calls, use the Region endpoint us-east-1.

Possible values:

  • CLOUDFRONT

  • REGIONAL

--description (string)

A description of the set that helps with identification. You cannot change the description of a set after you create it.

--regular-expression-list (list)

Array of regular expression strings.

A single regular expression. This is used in a RegexPatternSet .

RegexString -> (string)

The string representing the regular expression.

Shorthand Syntax:

RegexString=string ...

JSON Syntax:

[
  {
    "RegexString": "string"
  }
  ...
]

--tags (list)

An array of key:value pairs to associate with the resource.

A tag associated with an AWS resource. Tags are key:value pairs that you can use to categorize and manage your resources, for purposes like billing or other management. 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”. Or you might set the tag key to “customer” and the value to the customer name or ID. You can specify one or more tags to add to each AWS resource, up to 50 tags for a resource.

You can tag the AWS resources that you manage through AWS WAF: web ACLs, rule groups, IP sets, and regex pattern sets. You can’t manage or view tags through the AWS WAF console.

Key -> (string)

Part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as “customer.” Tag keys are case-sensitive.

Value -> (string)

Part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as “companyA” or “companyB.” Tag values are case-sensitive.

Shorthand Syntax:

Key=string,Value=string ...

JSON Syntax:

[
  {
    "Key": "string",
    "Value": "string"
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To create a regex pattern set for use in your web ACLs and rule groups

The following create-regex-pattern-set command creates a regex pattern set with two regex patterns specified.

aws wafv2 create-regex-pattern-set \
    --name regexPatterSet01 \
    --scope REGIONAL \
    --description 'Test web-acl' \
    --regular-expression-list '[{"RegexString": "/[0-9]*/"},{"RegexString": "/[a-z]*/"}]'

Output:

{
    "Summary":{
        "ARN":"arn:aws:wafv2:us-west-2:123456789012:regional/regexpatternset/regexPatterSet01/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111",
        "Description":"Test web-acl",
        "Name":"regexPatterSet01",
        "LockToken":"0bc01e21-03c9-4b98-9433-6229cbf1ef1c",
        "Id":"a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"
    }
}

Output

Summary -> (structure)

High-level information about a RegexPatternSet , returned by operations like create and list. This provides information like the ID, that you can use to retrieve and manage a RegexPatternSet , and the ARN, that you provide to the RegexPatternSetReferenceStatement to use the pattern set in a Rule .

Name -> (string)

The name of the data type instance. You cannot change the name after you create the instance.

Id -> (string)

A unique identifier for the set. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

Description -> (string)

A description of the set that helps with identification. You cannot change the description of a set after you create it.

LockToken -> (string)

A token used for optimistic locking. AWS WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. AWS WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException . If this happens, perform another get, and use the new token returned by that operation.

ARN -> (string)

The Amazon Resource Name (ARN) of the entity.
