To install it, use: ansible-galaxy collection install community.aws. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.aws.wafv2_web_acl.

New in community.aws 1.5.0

Synopsis

Requirements

The below requirements are needed on the host that executes this module.

  • python >= 3.6

Parameters

Parameter

Comments

access_key

the key of the body dictionary element.

Each element must have a unique dict key and in the dict two keys for content_type and content.

Requires botocore >= 1.20.40

debug_botocore_endpoint_logs

boolean

description

string

Description of wafv2 web acl.

endpoint_url

aliases: ec2_url, aws_endpoint_url, s3_url

string

URL to connect to instead of the default AWS endpoints. While this can be used to connection to other AWS-compatible services the amazon.aws and community.aws collections are only tested against AWS.

The AWS_URL or EC2_URL environment variables may also be used, in decreasing order of preference.

The ec2_url and s3_url aliases have been deprecated and will be removed in a release after 2024-12-01.

Support for the EC2_URL environment variable has been deprecated and will be removed in a release after 2024-12-01.

metric_name

string

Name of cloudwatch metrics.

If not given and cloudwatch_metrics is enabled, the name of the web acl itself will be taken.

name

string / required

The name of the web acl.

profile

aliases: aws_profile

string

A named AWS profile to use for authentication.

See the AWS documentation for more information about named profiles https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-profiles.html.

The AWS_PROFILE environment variable may also be used.

The profile option is mutually exclusive with the aws_access_key, aws_secret_key and security_token options.

purge_rules

boolean

When set to no, keep the existing load balancer rules in place. Will modify and add, but will not delete.

Choices:

  • false

  • true ← (default)

purge_tags

boolean

If purge_tags=true and tags is set, existing tags will be purged from the resource to match exactly what is defined by tags parameter.

If the tags parameter is not set then tags will not be modified, even if purge_tags=True.

Tag keys beginning with aws: are reserved by Amazon and can not be modified. As such they will be ignored for the purposes of the purge_tags parameter. See the Amazon documentation for more information https://docs.aws.amazon.com/general/latest/gr/aws_tagging.html#tag-conventions.

Choices:

  • false

  • true ← (default)

secret_key

aliases: aws_secret_access_key, aws_secret_key, ec2_secret_key

string

AWS secret access key.

See the AWS documentation for more information about access tokens https://docs.aws.amazon.com/general/latest/gr/aws-sec-cred-types.html#access-keys-and-secret-access-keys.

The AWS_SECRET_ACCESS_KEY, AWS_SECRET_KEY, or EC2_SECRET_KEY environment variables may also be used in decreasing order of preference.

Choices:

  • false

  • true ← (default)

Notes

Note

  • Support for the purge_tags parameter was added in release 4.0.0.

  • Caution: For modules, environment variables and configuration files are read from the Ansible ‘host’ context and not the ‘controller’ context. As such, files may need to be explicitly copied to the ‘host’. For lookup and connection plugins, environment variables and configuration files are read from the Ansible ‘controller’ context and not the ‘host’ context.

  • The AWS SDK (boto3) that Ansible uses may also read defaults for credentials and other settings, such as the region, from its configuration files in the Ansible ‘host’ context (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
