DESCRIPTION

Amazon EC2 Auto Scaling

Amazon EC2 Auto Scaling is designed to automatically launch or terminate EC2 instances based on user-defined scaling policies, scheduled actions, and health checks. Use this service with AWS Auto Scaling, Amazon CloudWatch, and Elastic Load Balancing.

For more information, including information about granting IAM users required permissions for Amazon EC2 Auto Scaling actions, see the Amazon EC2 Auto Scaling User Guide (https://docs.aws.amazon.com/autoscaling/ec2/userguide/what-is-amazon-ec2-auto-scaling.html).

For the AWS API documentation, see https://docs.aws.amazon.com/goto/WebAPI/autoscaling-2011-01-01

METHODS

AttachInstances

AutoScalingGroupName => Str
[InstanceIds => ArrayRef[Str|Undef]]

Each argument is described in detail in: Paws::AutoScaling::AttachInstances

Returns: nothing

Attaches one or more EC2 instances to the specified Auto Scaling group.

When you attach instances, Amazon EC2 Auto Scaling increases the desired capacity of the group by the number of instances being attached. If the number of instances being attached plus the desired capacity of the group exceeds the maximum size of the group, the operation fails.

If there is a Classic Load Balancer attached to your Auto Scaling group, the instances are also registered with the load balancer. If there are target groups attached to your Auto Scaling group, the instances are also registered with the target groups.

For more information, see Attach EC2 Instances to Your Auto Scaling Group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/attach-instance-asg.html) in the Amazon EC2 Auto Scaling User Guide.

AttachLoadBalancers

AutoScalingGroupName => Str
LoadBalancerNames => ArrayRef[Str|Undef]

Each argument is described in detail in: Paws::AutoScaling::AttachLoadBalancers

Returns: a Paws::AutoScaling::AttachLoadBalancersResultType instance

Attaches one or more Classic Load Balancers to the specified Auto Scaling group.

To attach an Application Load Balancer or a Network Load Balancer instead, see AttachLoadBalancerTargetGroups.

To describe the load balancers for an Auto Scaling group, use DescribeLoadBalancers. To detach the load balancer from the Auto Scaling group, use DetachLoadBalancers.

For more information, see Attaching a Load Balancer to Your Auto Scaling Group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/attach-load-balancer-asg.html) in the Amazon EC2 Auto Scaling User Guide.

AttachLoadBalancerTargetGroups

AutoScalingGroupName => Str
TargetGroupARNs => ArrayRef[Str|Undef]

Each argument is described in detail in: Paws::AutoScaling::AttachLoadBalancerTargetGroups

Returns: a Paws::AutoScaling::AttachLoadBalancerTargetGroupsResultType instance

Attaches one or more target groups to the specified Auto Scaling group.

To describe the target groups for an Auto Scaling group, use DescribeLoadBalancerTargetGroups. To detach the target group from the Auto Scaling group, use DetachLoadBalancerTargetGroups.

With Application Load Balancers and Network Load Balancers, instances are registered as targets with a target group. With Classic Load Balancers, instances are registered with the load balancer. For more information, see Attaching a Load Balancer to Your Auto Scaling Group (https://docs.aws.amazon.com/autoscaling/ec2/userguide/attach-load-balancer-asg.html) in the Amazon EC2 Auto Scaling User Guide.

LifecycleHookName => Str
[InstanceId => Str]
[LifecycleActionToken => Str]

Each argument is described in detail in: Paws::AutoScaling::CompleteLifecycleAction

Returns: a Paws::AutoScaling::CompleteLifecycleActionAnswer instance

Completes the lifecycle action for the specified token or instance with the specified result.

This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:

(Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Amazon EC2 Auto Scaling launches or terminates instances.
(Optional) Create a notification target and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle notifications to the target.
Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
If you finish before the timeout period ends, complete the lifecycle action.

For more information, see Amazon EC2 Auto Scaling Lifecycle Hooks (https://docs.aws.amazon.com/autoscaling/ec2/userguide/lifecycle-hooks.html) in the Amazon EC2 Auto Scaling User Guide.

CreateOrUpdateTags

Tags => ArrayRef[Paws::AutoScaling::Tag]

Each argument is described in detail in: Paws::AutoScaling::CreateOrUpdateTags

Returns: nothing

Creates or updates tags for the specified Auto Scaling group.

When you specify a tag with a key that already exists, the operation overwrites the previous tag definition, and you do not get an error message.

For more information, see Tagging Auto Scaling Groups and Instances (https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-tagging.html) in the Amazon EC2 Auto Scaling User Guide.

DeleteAutoScalingGroup

AutoScalingGroupName => Str
[ForceDelete => Bool]

Each argument is described in detail in: Paws::AutoScaling::DeleteAutoScalingGroup

Returns: nothing

Deletes the specified Auto Scaling group.

If the group has instances or scaling activities in progress, you must specify the option to force the deletion in order for it to succeed.

If the group has policies, deleting the group deletes the policies, the underlying alarm actions, and any alarm that no longer has an associated action.

To remove instances from the Auto Scaling group before deleting it, call DetachInstances with the list of instances and the option to decrement the desired capacity. This ensures that Amazon EC2 Auto Scaling does not launch replacement instances.

To terminate all instances before deleting the Auto Scaling group, call UpdateAutoScalingGroup and set the minimum size and desired capacity of the Auto Scaling group to zero.

DeleteLaunchConfiguration

LaunchConfigurationName => Str

Each argument is described in detail in: Paws::AutoScaling::DeleteLaunchConfiguration

[HeartbeatTimeout => Int]
[LifecycleTransition => Str]
[NotificationMetadata => Str]
[NotificationTargetARN => Str]
[RoleARN => Str]

Each argument is described in detail in: Paws::AutoScaling::PutLifecycleHook

Returns: a Paws::AutoScaling::PutLifecycleHookAnswer instance

Creates or updates a lifecycle hook for the specified Auto Scaling group.

A lifecycle hook tells Amazon EC2 Auto Scaling to perform an action on an instance when the instance launches (before it is put into service) or as the instance terminates (before it is fully terminated).

This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:

(Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Amazon EC2 Auto Scaling launches or terminates instances.
(Optional) Create a notification target and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle notifications to the target.
Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state using RecordLifecycleActionHeartbeat.
If you finish before the timeout period ends, complete the lifecycle action using CompleteLifecycleAction.

For more information, see Amazon EC2 Auto Scaling Lifecycle Hooks (https://docs.aws.amazon.com/autoscaling/ec2/userguide/lifecycle-hooks.html) in the Amazon EC2 Auto Scaling User Guide.

If you exceed your maximum limit of lifecycle hooks, which by default is 50 per Auto Scaling group, the call fails.

You can view the lifecycle hooks for an Auto Scaling group using DescribeLifecycleHooks. If you are no longer using a lifecycle hook, you can delete it using DeleteLifecycleHook.

[LifecycleActionToken => Str]

Each argument is described in detail in: Paws::AutoScaling::RecordLifecycleActionHeartbeat

Returns: a Paws::AutoScaling::RecordLifecycleActionHeartbeatAnswer instance

Records a heartbeat for the lifecycle action associated with the specified token or instance. This extends the timeout by the length of time defined using PutLifecycleHook.

This step is a part of the procedure for adding a lifecycle hook to an Auto Scaling group:

(Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Amazon EC2 Auto Scaling launches or terminates instances.
(Optional) Create a notification target and an IAM role. The target can be either an Amazon SQS queue or an Amazon SNS topic. The role allows Amazon EC2 Auto Scaling to publish lifecycle notifications to the target.
Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
If you finish before the timeout period ends, complete the lifecycle action.

[ScalingProcesses => ArrayRef[Str|Undef]]

Each argument is described in detail in: Paws::AutoScaling::SuspendProcesses

Returns: nothing

Suspends the specified automatic scaling processes, or all processes, for the specified Auto Scaling group.

If you suspend either the Launch or Terminate process types, it can prevent other process types from functioning properly.

To resume processes that have been suspended, use ResumeProcesses.

TerminateInstanceInAutoScalingGroup

InstanceId => Str
ShouldDecrementDesiredCapacity => Bool

Each argument is described in detail in: Paws::AutoScaling::TerminateInstanceInAutoScalingGroup

Returns: a Paws::AutoScaling::ActivityType instance

Terminates the specified instance and optionally adjusts the desired group size. This call simply makes a termination request. The instance is not terminated immediately. When an instance is terminated, the instance status changes to terminated. You can't connect to or start an instance after you've terminated it.

If you do not specify the option to decrement the desired capacity, Amazon EC2 Auto Scaling launches instances to replace the ones that are terminated.

By default, Amazon EC2 Auto Scaling balances instances across all Availability Zones. If you decrement the desired capacity, your Auto Scaling group can become unbalanced between Availability Zones. Amazon EC2 Auto Scaling tries to rebalance the group, and rebalancing might terminate instances in other zones. For more information, see Rebalancing Activities (https://docs.aws.amazon.com/autoscaling/ec2/userguide/auto-scaling-benefits.html#AutoScalingBehavior.InstanceUsage) in the Amazon EC2 Auto Scaling User Guide.

Returns: nothing

Updates the configuration for the specified Auto Scaling group.

To update an Auto Scaling group, specify the name of the group and the parameter that you want to change. Any parameters that you don't specify are not changed by this update request. The new settings take effect on any scaling activities after this call returns.

If you associate a new launch configuration or template with an Auto Scaling group, all new instances will get the updated configuration. Existing instances continue to run with the configuration that they were originally launched with. When you update a group to specify a mixed instances policy instead of a launch configuration or template, existing instances may be replaced to match the new purchasing options that you specified in the policy. For example, if the group currently has 100% On-Demand capacity and the policy specifies 50% Spot capacity, this means that half of your instances will be gradually terminated and relaunched as Spot Instances. When replacing instances, Amazon EC2 Auto Scaling launches new instances before terminating the old ones, so that updating your group does not compromise the performance or availability of your application.

Note the following about changing DesiredCapacity, MaxSize, or MinSize:

If a scale-in event occurs as a result of a new DesiredCapacity value that is lower than the current size of the group, the Auto Scaling group uses its termination policy to determine which instances to terminate.
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, this sets the group's DesiredCapacity to the new MinSize value.
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, this sets the group's DesiredCapacity to the new MaxSize value.

To see which parameters have been set, use DescribeAutoScalingGroups. You can also view the scaling policies for an Auto Scaling group using DescribePolicies. If the group has scaling policies, you can update them using PutScalingPolicy.
