Changes Update autoscaling client to latest version
{'LaunchTemplate': {'LaunchTemplateId': 'string',
'LaunchTemplateName': 'string',
'Version': 'string'}}
Creates an Auto Scaling group with the specified name and attributes.
If you exceed your maximum limit of Auto Scaling groups, which by default is 20 per region, the call fails. For information about viewing and updating this limit, see DescribeAccountLimits.

string
[REQUIRED]
The name of the Auto Scaling group. This name must be unique within the scope of your AWS account.
string
The name of the launch configuration. You must specify one of the following: a launch configuration, a launch template, or an EC2 instance.
dict
The launch template to use to launch instances. You must specify one of the following: a launch template, a launch configuration, or an EC2 instance.
LaunchTemplateId (string) --
The ID of the launch template. You must specify either a template ID or a template name.
LaunchTemplateName (string) --
The name of the launch template. You must specify either a template name or a template ID.
Version (string) --
The version number. By default, the default version of the launch template is used.
string
The ID of the instance used to create a launch configuration for the group. You must specify one of the following: an EC2 instance, a launch configuration, or a launch template.
When you specify an ID of an instance, Auto Scaling creates a new launch configuration and associates it with the group. This launch configuration derives its attributes from the specified instance, with the exception of the block device mapping.
For more information, see Create an Auto Scaling Group Using an EC2 Instance in the Auto Scaling User Guide.
integer
[REQUIRED]
The minimum size of the group.
integer
[REQUIRED]
The maximum size of the group.
integer
The number of EC2 instances that should be running in the group. This number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group. If you do not specify a desired capacity, the default is the minimum size of the group.
integer
The amount of time, in seconds, after a scaling activity completes before another scaling activity can start. The default is 300.
For more information, see Auto Scaling Cooldowns in the Auto Scaling User Guide.
list
One or more Availability Zones for the group. This parameter is optional if you specify one or more subnets.
(string) --
list
One or more Classic Load Balancers. To specify an Application Load Balancer, use TargetGroupARNs instead.
For more information, see Using a Load Balancer With an Auto Scaling Group in the Auto Scaling User Guide.
(string) --
list
The Amazon Resource Names (ARN) of the target groups.
(string) --
string
The service to use for the health checks. The valid values are EC2 and ELB.
By default, health checks use Amazon EC2 instance status checks to determine the health of an instance. For more information, see Health Checks in the Auto Scaling User Guide.
integer
The amount of time, in seconds, that Auto Scaling waits before checking the health status of an EC2 instance that has come into service. During this time, any health check failures for the instance are ignored. The default is 0.
This parameter is required if you are adding an ELB health check.
For more information, see Health Checks in the Auto Scaling User Guide.
string
The name of the placement group into which you'll launch your instances, if any. For more information, see Placement Groups in the Amazon Elastic Compute Cloud User Guide.
string
A comma-separated list of subnet identifiers for your virtual private cloud (VPC).
If you specify subnets and Availability Zones with this call, ensure that the subnets' Availability Zones match the Availability Zones specified.
For more information, see Launching Auto Scaling Instances in a VPC in the Auto Scaling User Guide.
list
One or more termination policies used to select the instance to terminate. These policies are executed in the order that they are listed.
For more information, see Controlling Which Instances Auto Scaling Terminates During Scale In in the Auto Scaling User Guide.
(string) --
boolean
Indicates whether newly launched instances are protected from termination by Auto Scaling when scaling in.
list
One or more lifecycle hooks.
(dict) --
Describes a lifecycle hook, which tells Auto Scaling that you want to perform an action whenever it launches instances or whenever it terminates instances.

NotificationMetadata (string) --
Additional information that you want to include any time Auto Scaling sends a message to the notification target.
HeartbeatTimeout (integer) --
The maximum time, in seconds, that can elapse before the lifecycle hook times out. If the lifecycle hook times out, Auto Scaling performs the default action. You can prevent the lifecycle hook from timing out by calling RecordLifecycleActionHeartbeat.
DefaultResult (string) --
Defines the action the Auto Scaling group should take when the lifecycle hook timeout elapses or if an unexpected failure occurs. The valid values are CONTINUE and ABANDON.
NotificationTargetARN (string) --
The ARN of the target that Auto Scaling sends notifications to when an instance is in the transition state for the lifecycle hook. The notification target can be either an SQS queue or an SNS topic.
RoleARN (string) --
The ARN of the IAM role that allows the Auto Scaling group to publish to the specified notification target.

Updates the configuration for the specified Auto Scaling group.
The new settings take effect on any scaling activities after this call returns. Scaling activities that are currently in progress aren't affected.
To update an Auto Scaling group with a launch configuration with InstanceMonitoring set to false, you must first disable the collection of group metrics. Otherwise, you will get an error. If you have previously enabled the collection of group metrics, you can disable it using DisableMetricsCollection.
Note the following:
If you specify a new value for MinSize without specifying a value for DesiredCapacity, and the new MinSize is larger than the current size of the group, we implicitly call SetDesiredCapacity to set the size of the group to the new value of MinSize.
If you specify a new value for MaxSize without specifying a value for DesiredCapacity, and the new MaxSize is smaller than the current size of the group, we implicitly call SetDesiredCapacity to set the size of the group to the new value of MaxSize.
All other optional parameters are left unchanged if not specified.
