Fields

The following fields are returned by SELECT queries:

NameDatatypeDescription
lock_tokenstringA token used for optimistic locking. 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. 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. (pattern: <code>^[0-9a-f]{8}-(?:[0-9a-f]{4}-){3}[0-9a-f]{12}$</code>)
regex_pattern_setobjectContains one or more regular expressions. WAF assigns an ARN to each RegexPatternSet that you create. To use a set in a rule, you provide the ARN to the Rule statement RegexPatternSetReferenceStatement.

Methods

The following methods are available for this resource:

NameAccessible byRequired ParamsOptional ParamsDescription
get_regex_pattern_setselectregionRetrieves the specified RegexPatternSet.
list_regex_pattern_setsselectregionRetrieves an array of RegexPatternSetSummary objects for the regex pattern sets that you manage.
create_regex_pattern_setinsertregion, Name, Scope, RegularExpressionListCreates a RegexPatternSet, which you reference in a RegexPatternSetReferenceStatement, to have WAF inspect a web request component for the specified patterns.
update_regex_pattern_setupdateregion, Name, Scope, Id, RegularExpressionList, LockTokenUpdates the specified RegexPatternSet. This operation completely replaces the mutable specifications that you already have for the regex pattern set with the ones that you provide to this call. To modify a regex pattern set, do the following: Retrieve it by calling GetRegexPatternSet Update its settings as needed Provide the complete regex pattern set specification to this call Temporary inconsistencies during updates When you create or change a web ACL or other WAF resources, the changes take a small amount of time to propagate to all areas where the resources are stored. The propagation time can be from a few seconds to a number of minutes. The following are examples of the temporary inconsistencies that you might notice during change propagation: After you create a web ACL, if you try to associate it with a resource, you might get an exception indicating that the web ACL is unavailable. After you add a rule group to a web ACL, the new rule group rules might be in effect in one area where the web ACL is used and not in another. After you change a rule action setting, you might see the old action in some places and the new action in others. After you add an IP address to an IP set that is in use in a blocking rule, the new address might be blocked in one area while still allowed in another.
delete_regex_pattern_setdeleteregionDeletes the specified RegexPatternSet.

Parameters

Parameters can be passed in the WHERE clause of a query. Check the Methods section to see which parameters are required or optional for each operation.

SELECT examples

Retrieves the specified RegexPatternSet.

SELECT

regex_pattern_set
FROM aws.wafv2.regex_pattern_sets
WHERE region = '{{ region }}' -- required
;

INSERT examples

Creates a RegexPatternSet, which you reference in a RegexPatternSetReferenceStatement, to have WAF inspect a web request component for the specified patterns.

INSERT INTO aws.wafv2.regex_pattern_sets (
Name,
Scope,
Description,
RegularExpressionList,
Tags,

)
SELECT
'{{ Name }}' /* required */,
'{{ Scope }}' /* required */,
'{{ Description }}',
'{{ RegularExpressionList }}' /* required */,
'{{ Tags }}',
'{{ region }}'
RETURNING
