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
    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.
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 the policy type is StepScaling.
target_tracking_scaling_policy_configuration
dictionary
A target tracking policy. This parameter is required if you are creating a new policy and the policy type is 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
    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.
