The identifier of the resource associated with the scalable target.
|
|
scalable_dimension
-
/ required
|

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.
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
boolean
|
|
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
orEC2_URL
,AWS_ACCESS_KEY_ID
orAWS_ACCESS_KEY
orEC2_ACCESS_KEY
,AWS_SECRET_ACCESS_KEY
orAWS_SECRET_KEY
orEC2_SECRET_KEY
,AWS_SECURITY_TOKEN
orEC2_SECURITY_TOKEN
,AWS_REGION
orEC2_REGION
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
orEC2_REGION
can be typically be used to specify the AWS region, when required, but this can also be configured in the boto config file
