New in version 2.5.
The below requirements are needed on the host that executes this module.
Parameter | Choices/Defaults | Comments |
---|---|---|
aws_access_key | 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. aliases: ec2_access_key, access_key | |

ec2_url | 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. | |
maximum_tasks (added in 2.6) | 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 (added in 2.6) | 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 bool (added in 2.6) |
| Whether or not to override values of minimum and/or maximum tasks if it's already set. |
policy_name required | The name of the scaling policy. | |
policy_type required |
| The policy type. |
profile (added in 1.6) | Uses a boto profile. Only works with boto >= 2.24.0. | |
region | 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 required | The identifier of the resource associated with the scalable target. | |
scalable_dimension required |
| The scalable dimension associated with the scalable target. |
security_token (added in 1.6) | AWS STS security token. If not set then the value of the AWS_SECURITY_TOKEN or EC2_SECURITY_TOKEN environment variable is used. aliases: access_token | |
service_namespace required |
| The namespace of the AWS service. |
step_scaling_policy_configuration | 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 | A target tracking policy. This parameter is required if you are creating a new policy and the policy type is TargetTrackingScaling. | |
validate_certs bool (added in 1.5) |
| When set to "no", SSL certificates will not be validated for boto versions >= 2.6.0. |
