associate-web-acl

Description

Associates a web ACL with a regional application resource, to protect the resource. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, or an AppSync GraphQL API.

For Amazon CloudFront, don’t use this call. Instead, use your CloudFront distribution configuration. To associate a web ACL, in the CloudFront call UpdateDistribution , set the web ACL ID to the Amazon Resource Name (ARN) of the web ACL. For information, see UpdateDistribution .

When you make changes to web ACLs or web ACL components, like rules and rule groups, WAF propagates the changes everywhere that the web ACL and its components are stored and used. Your changes are applied within seconds, but there might be a brief period of inconsistency when the changes have arrived in some places and not in others. So, for example, if you change a rule action setting, the action might be the old action in one area and the new action in another area. Or if you add an IP address to an IP set used in a blocking rule, the new address might briefly be blocked in one area while still allowed in another. This temporary inconsistency can occur when you first associate a web ACL with an Amazon Web Services resource and when you change a web ACL that is already associated with a resource. Generally, any inconsistencies of this type last only a few seconds.

Synopsis

  associate-web-acl
--web-acl-arn <value>
--resource-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--web-acl-arn (string)

The Amazon Resource Name (ARN) of the web ACL that you want to associate with the resource.

--resource-arn (string)

The Amazon Resource Name (ARN) of the resource to associate with the web ACL.

The ARN must be in one of the following formats:

• For an Application Load Balancer: ``arn:aws:elasticloadbalancing:region :account-id :loadbalancer/app/load-balancer-name /load-balancer-id ``

• For an Amazon API Gateway REST API: ``arn:aws:apigateway:region ::/restapis/api-id /stages/stage-name ``

• For an AppSync GraphQL API: ``arn:aws:appsync:region :account-id :apis/GraphQLApiId ``

--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 associate a web ACL with a regional AWS resource

The following associate-web-acl example associates the specified web ACL with an Application Load Balancer.

aws wafv2 associate-web-acl \
    --web-acl-arn arn:aws:wafv2:us-west-2:123456789012:regional/webacl/test-cli/a1b2c3d4-5678-90ab-cdef-EXAMPLE11111 \
    --resource-arn arn:aws:elasticloadbalancing:us-west-2:123456789012:loadbalancer/app/waf-cli-alb/1ea17125f8b25a2a \
    --region us-west-2

This command produces no output.
