Note

This plugin is part of the community.aws collection (version 1.5.0).

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.

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

New in version 1.0.0: of community.aws

Synopsis

Creates, updates or removes a Scaling Policy.

Requirements

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

boto
boto3
botocore
json
python >= 2.6

Parameters

Parameter		Choices/Defaults	Comments
aws_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. aliases: ec2_access_key, access_key
aws_ca_bundle path			The location of a CA Bundle to use when validating SSL certificates. Only used for boto3 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 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. aliases: ec2_secret_key, secret_key
debug_botocore_endpoint_logs boolean		Choices: no ← yes	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.
ec2_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. aliases: aws_endpoint_url, endpoint_url
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.
override_task_capacity boolean		Choices: no yes	Whether or not to override values of minimum and/or maximum tasks if it's already set. Defaults to `false`.
policy_name string / required			The name of the scaling policy.
policy_type string / required		Choices: StepScaling TargetTrackingScaling	The policy type.
profile string			Uses a boto profile. Only works with boto >= 2.24.0. 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. aliases: aws_profile
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 aliases: aws_region, ec2_region
resource_id string / required			The identifier of the resource associated with the scalable target.
scalable_dimension string / required		Choices: ecs:service:DesiredCount ec2:spot-fleet-request:TargetCapacity elasticmapreduce:instancegroup:InstanceCount appstream:fleet:DesiredCapacity dynamodb:table:ReadCapacityUnits dynamodb:table:WriteCapacityUnits dynamodb:index:ReadCapacityUnits dynamodb:index:WriteCapacityUnits	The scalable dimension associated with the scalable target.
security_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_security_token, access_token
service_namespace string / required		Choices: ecs elasticmapreduce ec2 appstream dynamodb	The namespace of the AWS service.
state string / required		Choices: absent present	Whether a policy should be `present` or `absent`.
step_scaling_policy_configuration dictionary			A step scaling policy. This parameter is required if you are creating a policy and policy_type=StepScaling.
target_tracking_scaling_policy_configuration dictionary			A target tracking policy. This parameter is required if you are creating a new policy and policy_type=TargetTrackingScaling. 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	Choices: no yes	Whether scaling-in should be disabled.
	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		Choices: no yes ←	When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.

Notes

Note

for details of the parameters and returns see http://boto3.readthedocs.io/en/latest/reference/services/application-autoscaling.html#ApplicationAutoScaling.Client.put_scaling_policy
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
Ansible uses the boto configuration file (typically ~/.boto) if no credentials are provided. See https://boto.readthedocs.io/en/latest/boto_config_tut.html
AWS_REGION or EC2_REGION can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
