community.aws.wafv2_web_acl module – Create and delete WAF Web ACLs

Note

This module is part of the community.aws collection (version 3.6.0).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. To check whether it is installed, run ansible-galaxy collection list.

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 

Create, modify or delete AWS WAF v2 web ACLs (not for classic WAF).
See docs at https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html

Requirements 

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

python >= 3.6
boto3 >= 1.16.0
botocore >= 1.19.0

Parameters 

Parameter	Comments
aws_access_key aliases: ec2_access_key, access_key string	`AWS access key`. If not set then the value of the `AWS_ACCESS_KEY_ID`, `AWS_ACCESS_KEY` or `EC2_ACCESS_KEY` environment variable is used. If profile is set this parameter is ignored. Passing the aws_access_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. Not used by boto 2 based modules. Note: The CA Bundle is read ‘module’ side and may need to be explicitly copied from the controller if not run locally.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found at https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config. Only the ‘user_agent’ key is used for boto modules. See http://boto.cloudhackers.com/en/latest/boto_config_tut.html#boto for more boto configuration.
aws_secret_key aliases: ec2_secret_key, secret_key string	`AWS secret key`. If not set then the value of the `AWS_SECRET_ACCESS_KEY`, `AWS_SECRET_KEY`, or `EC2_SECRET_KEY` environment variable is used. If profile is set this parameter is ignored. Passing the aws_secret_key and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01.
cloudwatch_metrics boolean	Enable cloudwatch metric for wafv2 web acl. Choices: `false` `true` ← (default)
custom_response_bodies dictionary added in community.aws 3.1.0	A map of custom response keys and content bodies. Define response bodies here and reference them in the rules by providing 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	Use a botocore.endpoint logger to parse the unique (rather than total) “resource:action” API calls made during a task, outputing the set to the resource_actions key in the task results. Use the aws_resource_action callback to output to total list made during a playbook. The ANSIBLE_DEBUG_BOTOCORE_LOGS environment variable may also be used. Choices: `false` ← (default) `true`
default_action string	Default action of the wafv2 web acl. Choices: `"Block"` `"Allow"`
description string	Description of wafv2 web acl.
ec2_url aliases: aws_endpoint_url, endpoint_url string	URL to use to connect to EC2 or your Eucalyptus cloud (by default the module will use EC2 endpoints). Ignored for modules where region is required. Must be specified for all other modules if region is not used. If not set then the value of the EC2_URL environment variable, if any, is used.
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	Using profile will override aws_access_key, aws_secret_key and security_token and support for passing them at the same time as profile has been deprecated. aws_access_key, aws_secret_key and security_token will be made mutually exclusive with profile after 2022-06-01.
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)
region aliases: aws_region, ec2_region string	The AWS region to use. If not specified then the value of the AWS_REGION or EC2_REGION environment variable, if any, is used. See http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region
rules list / elements=dictionary	The Rule statements used to identify the web requests that you want to allow, block, or count. For a list of managed rules see https://docs.aws.amazon.com/waf/latest/developerguide/aws-managed-rule-groups-list.html.
action dictionary	Wether a rule is blocked, allowed or counted.
name string	The name of the wafv2 rule
priority integer	The rule priority
statement dictionary	Rule configuration.
visibility_config dictionary	Visibility of single wafv2 rule.
sampled_requests boolean	Whether to store a sample of the web requests, true or false. Choices: `false` ← (default) `true`
scope string / required	Geographical scope of the web acl. Choices: `"CLOUDFRONT"` `"REGIONAL"`
security_token aliases: aws_session_token, session_token, aws_security_token, access_token string	`AWS STS security token`. If not set then the value of the `AWS_SECURITY_TOKEN` or `EC2_SECURITY_TOKEN` environment variable is used. If profile is set this parameter is ignored. Passing the security_token and profile options at the same time has been deprecated and the options will be made mutually exclusive after 2022-06-01. Aliases aws_session_token and session_token have been added in version 3.2.0.
state string / required	Whether the rule is present or absent. Choices: `"present"` `"absent"`
tags dictionary	tags for wafv2 web acl.
validate_certs boolean	When set to “no”, SSL certificates will not be validated for communication with the AWS APIs. Choices: `false` `true` ← (default)

Notes 

Note

If parameters are not set within the module, the following environment variables can be used in decreasing order of precedence AWS_URL or EC2_URL, AWS_PROFILE or AWS_DEFAULT_PROFILE, AWS_ACCESS_KEY_ID or AWS_ACCESS_KEY or EC2_ACCESS_KEY, AWS_SECRET_ACCESS_KEY or AWS_SECRET_KEY or EC2_SECRET_KEY, AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN, AWS_REGION or EC2_REGION, AWS_CA_BUNDLE
When no credentials are explicitly provided the AWS SDK (boto3) that Ansible uses will fall back to its configuration files (typically ~/.aws/credentials). See https://boto3.amazonaws.com/v1/documentation/api/latest/guide/credentials.html for more information.
Modules based on the original AWS SDK (boto) may read their default configuration from different files. See https://boto.readthedocs.io/en/latest/boto_config_tut.html for more information.
AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be defined in the configuration files.
