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.

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

  • 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

  • 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

  • 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

  • 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

  • ecs
  • elasticmapreduce
  • ec2
  • appstream
  • dynamodb

The namespace of the AWS service.

state

string / required

  • 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:

CustomizedMetricSpecification

dictionary

The metric to use if using a customized metric.

DisableScaleIn

boolean

  • 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

  • no
  • yes

When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0.
