Parameters

Parameter	Comments
access_key aliases: aws_access_key_id, aws_access_key, ec2_access_key string	AWS access key ID. 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_ACCESS_KEY_ID, AWS_ACCESS_KEY or EC2_ACCESS_KEY environment variables may also be used in decreasing order of preference. The aws_access_key and profile options are mutually exclusive. The aws_access_key_id alias was added in release 5.1.0 for consistency with the AWS botocore SDK. The ec2_access_key alias has been deprecated and will be removed in a release after 2024-12-01. Support for the EC2_ACCESS_KEY environment variable has been deprecated and will be removed in a release after 2024-12-01.
aws_ca_bundle path	The location of a CA Bundle to use when validating SSL certificates. The AWS_CA_BUNDLE environment variable may also be used.
aws_config dictionary	A dictionary to modify the botocore configuration. Parameters can be found in the AWS documentation https://botocore.amazonaws.com/v1/documentation/api/latest/reference/config.html#botocore.config.Config.
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
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.
maximum_tasks integer	The maximum value to scale to in response to a scale out event. This parameter is required if you are creating a first new policy for the specified service.
minimum_tasks integer	The minimum value to scale to in response to a scale in event. This parameter is required if you are creating a first new policy for the specified service.

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.
region aliases: aws_region, ec2_region string	The AWS region to use. For global services such as IAM, Route53 and CloudFront, region is ignored. The AWS_REGION or EC2_REGION environment variables may also be used. See the Amazon AWS documentation for more information http://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region. The ec2_region alias has been deprecated and will be removed in a release after 2024-12-01 Support for the EC2_REGION environment variable has been deprecated and will be removed in a release after 2024-12-01.
resource_id string / required	The identifier of the resource associated with the scalable target.
scalable_dimension string / required	The scalable dimension associated with the scalable target.

Full documentation of the suboptions can be found in the API documentation: https://docs.aws.amazon.com/autoscaling/application/APIReference/API_TargetTrackingScalingPolicyConfiguration.html
CustomizedMetricSpecification dictionary	The metric to use if using a customized metric.
DisableScaleIn boolean	Whether scaling-in should be disabled. Choices: false true
PredefinedMetricSpecification dictionary	The metric to use if using a predefined metric.
ScaleInCooldown integer	The time (in seconds) to wait after scaling-in before another scaling action can occur.
ScaleOutCooldown integer	The time (in seconds) to wait after scaling-out before another scaling action can occur.
TargetValue float	The target value for the metric.
validate_certs boolean	When set to false, SSL certificates will not be validated for communication with the AWS APIs. Setting validate_certs=false is strongly discouraged, as an alternative, consider setting aws_ca_bundle instead. Choices: false true ← (default)

Notes

Note

• For more details of the parameters and returns see http://boto3.readthedocs.io/en/latest/reference/services/application-autoscaling.html#ApplicationAutoScaling.Client.put_scaling_policy

• 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.
