Returns: a Paws::AutoScaling::AttachLoadBalancersResultType instance

Attaches one or more load balancers to the specified Auto Scaling group.

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 Attach a Load Balancer to Your Auto Scaling Group in the Auto Scaling Developer Guide.

CompleteLifecycleAction(AutoScalingGroupName => Str, LifecycleActionResult => Str, LifecycleActionToken => Str, LifecycleHookName => Str)

Returns: a Paws::AutoScaling::CompleteLifecycleActionAnswer instance

Completes the lifecycle action for the associated token initiated under the given lifecycle hook with the specified result.

This operation is a part of the basic sequence for adding a lifecycle hook to an Auto Scaling group:

1. Create a notification target. A target can be either an Amazon SQS queue or an Amazon SNS topic.

2. Create an IAM role. This role allows Auto Scaling to publish lifecycle notifications to the designated SQS queue or SNS topic.

3. Create the lifecycle hook. You can create a hook that acts when instances launch or when instances terminate.

4. If necessary, record the lifecycle action heartbeat to keep the instance in a pending state.

5. Complete the lifecycle action.

For more information, see Auto Scaling Pending State and Auto Scaling Terminating State in the Auto Scaling Developer Guide.

CreateOrUpdateTags(Tags => ArrayRef[Paws::AutoScaling::Tag])

Returns: nothing

Creates or updates tags for the specified Auto Scaling group.

A tag is defined by its resource ID, resource type, key, value, and propagate flag. The value and the propagate flag are optional parameters. The only supported resource type is "auto-scaling-group", and the resource ID must be the name of the group. The "PropagateAtLaunch" flag determines whether the tag is added to instances launched in the group. Valid values are "true" or "false".

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 in the Auto Scaling Developer Guide.

Returns: a Paws::AutoScaling::PutLifecycleHookAnswer instance

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

A lifecycle hook tells Auto Scaling that you want to perform an action on an instance that is not actively in service; for example, either when the instance launches or before the instance terminates.

This operation is a part of the basic sequence for adding a lifecycle hook to an Auto Scaling group:

1. Create a notification target. A target can be either an Amazon SQS queue or an Amazon SNS topic.

2. Create an IAM role. This role allows Auto Scaling to publish lifecycle notifications to the designated SQS queue or SNS topic.

3. Create the lifecycle hook. You can create a hook that acts when instances launch or when instances terminate.

4. If necessary, record the lifecycle action heartbeat to keep the instance in a pending state.

5. Complete the lifecycle action.

For more information, see Auto Scaling Pending State and Auto Scaling Terminating State in the Auto Scaling Developer Guide.

If you exceed your maximum limit of lifecycle hooks, which by default is 50 per region, the call fails. For information about updating this limit, see AWS Service Limits in the Amazon Web Services General Reference.

PutNotificationConfiguration(AutoScalingGroupName => Str, NotificationTypes => ArrayRef[Str], TopicARN => Str)

Returns: a Paws::AutoScaling::PolicyARNType instance

Creates or updates a policy for an Auto Scaling group. To update an existing policy, use the existing policy name and set the parameters you want to change. Any existing parameter not changed in an update to an existing policy is not changed in this update request.

If you exceed your maximum limit of step adjustments, which by default is 20 per region, the call fails. For information about updating this limit, see AWS Service Limits in the Amazon Web Services General Reference.

PutScheduledUpdateGroupAction(AutoScalingGroupName => Str, ScheduledActionName => Str, [DesiredCapacity => Int, EndTime => Str, MaxSize => Int, MinSize => Int, Recurrence => Str, StartTime => Str, Time => Str])

Returns: a Paws::AutoScaling::RecordLifecycleActionHeartbeatAnswer instance

Records a heartbeat for the lifecycle action associated with a specific token. This extends the timeout by the length of time defined by the "HeartbeatTimeout" parameter of PutLifecycleHook.

This operation is a part of the basic sequence for adding a lifecycle hook to an Auto Scaling group:

1. Create a notification target. A target can be either an Amazon SQS queue or an Amazon SNS topic.

2. Create an IAM role. This role allows Auto Scaling to publish lifecycle notifications to the designated SQS queue or SNS topic.

3. Create the lifecycle hook. You can create a hook that acts when instances launch or when instances terminate.

4. If necessary, record the lifecycle action heartbeat to keep the instance in a pending state.

5. Complete the lifecycle action.

For more information, see Auto Scaling Pending State and Auto Scaling Terminating State in the Auto Scaling Developer Guide.

ResumeProcesses(AutoScalingGroupName => Str, [ScalingProcesses => ArrayRef[Str]])

Returns: nothing

Resumes the specified suspended Auto Scaling processes for the specified Auto Scaling group. To resume specific processes, use the "ScalingProcesses" parameter. To resume all processes, omit the "ScalingProcesses" parameter. For more information, see Suspend and Resume Auto Scaling Processes in the Auto Scaling Developer Guide.

SetDesiredCapacity(AutoScalingGroupName => Str, DesiredCapacity => Int, [HonorCooldown => Bool])

Returns: nothing

Sets the size of the specified Auto Scaling group.

For more information about desired capacity, see What Is Auto Scaling? in the Auto Scaling Developer Guide.

Returns: nothing

Suspends the specified Auto Scaling processes for the specified Auto Scaling group. To suspend specific processes, use the "ScalingProcesses" parameter. To suspend all processes, omit the "ScalingProcesses" parameter.

Note that 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.

For more information, see Suspend and Resume Auto Scaling Processes in the Auto Scaling Developer Guide.

TerminateInstanceInAutoScalingGroup(InstanceId => Str, ShouldDecrementDesiredCapacity => Bool)

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 instances is not terminated immediately.

Returns: nothing

Updates the configuration for the specified Auto Scaling group.

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.

The new settings are registered upon the completion of this call. Any launch configuration settings take effect on any triggers after this call returns. Scaling activities that are currently in progress aren't affected.

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.
