public void setEndpoint(String endpoint)
AmazonAutoScaling
Callers can pass in just the endpoint (ex: "autoscaling.amazonaws.com") or a full URL, including the protocol
(ex: "https://autoscaling.amazonaws.com"). If the protocol is not specified here, the default protocol from this
client's ClientConfiguration
will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

endpoint
- The endpoint (ex: "autoscaling.amazonaws.com") or a full URL, including the protocol (ex:
"https://autoscaling.amazonaws.com") of the region specific AWS endpoint this client will communicate
with.public void setRegion(Region region)
AmazonAutoScaling
AmazonAutoScaling.setEndpoint(String)
, sets the regional endpoint for this client's
service calls. Callers can use this method to control which AWS region they want to work with.
By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the
ClientConfiguration
supplied at construction.
This method is not threadsafe. A region should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

public AttachInstancesResult attachInstances(AttachInstancesRequest request)
AmazonAutoScaling
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 in the Amazon EC2 Auto Scaling User Guide.
attachInstances
in interface AmazonAutoScaling
public AttachLoadBalancerTargetGroupsResult attachLoadBalancerTargetGroups(AttachLoadBalancerTargetGroupsRequest request)
AmazonAutoScaling
Attaches one or more target groups to the specified Auto Scaling group.
To describe the target groups for an Auto Scaling group, call the DescribeLoadBalancerTargetGroups API. To detach the target group from the Auto Scaling group, call the DetachLoadBalancerTargetGroups API.
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 in the Amazon EC2 Auto Scaling User Guide.
attachLoadBalancerTargetGroups
in interface AmazonAutoScaling
public AttachLoadBalancersResult attachLoadBalancers(AttachLoadBalancersRequest request)
AmazonAutoScaling
To attach an Application Load Balancer or a Network Load Balancer, use the AttachLoadBalancerTargetGroups API operation instead.
Attaches one or more Classic Load Balancers to the specified Auto Scaling group. Amazon EC2 Auto Scaling registers the running instances with these Classic Load Balancers.
To describe the load balancers for an Auto Scaling group, call the DescribeLoadBalancers API. To detach the load balancer from the Auto Scaling group, call the DetachLoadBalancers API.
For more information, see Attaching a load balancer to your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

public CancelInstanceRefreshResult cancelInstanceRefresh(CancelInstanceRefreshRequest request)
AmazonAutoScaling
Cancels an instance refresh operation in progress. Cancellation does not roll back any replacements that have already been completed, but it prevents new replacements from being started.
For more information, see Replacing Auto Scaling Instances Based on an Instance Refresh.
cancelInstanceRefresh
in interface AmazonAutoScaling
public CompleteLifecycleActionResult completeLifecycleAction(CompleteLifecycleActionRequest request)
AmazonAutoScaling
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 in the Amazon EC2 Auto Scaling User Guide.
completeLifecycleAction
in interface AmazonAutoScaling
public CreateAutoScalingGroupResult createAutoScalingGroup(CreateAutoScalingGroupRequest request)
AmazonAutoScaling
Creates an Auto Scaling group with the specified name and attributes.
If you exceed your maximum limit of Auto Scaling groups, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see Amazon EC2 Auto Scaling service quotas in the Amazon EC2 Auto Scaling User Guide.
For introductory exercises for creating an Auto Scaling group, see Getting started with Amazon EC2 Auto Scaling and Tutorial: Set up a scaled and load-balanced application in the Amazon EC2 Auto Scaling User Guide. For more information, see Auto Scaling groups in the Amazon EC2 Auto Scaling User Guide.
Every Auto Scaling group has three size parameters (DesiredCapacity
, MaxSize
, and
MinSize
). Usually, you set these sizes based on a specific number of instances. However, if you
configure a mixed instances policy that defines weights for the instance types, you must specify these sizes with
the same units that you use for weighting instances.
createAutoScalingGroup
in interface AmazonAutoScaling
public CreateLaunchConfigurationResult createLaunchConfiguration(CreateLaunchConfigurationRequest request)
AmazonAutoScaling
Creates a launch configuration.
If you exceed your maximum limit of launch configurations, the call fails. To query this limit, call the DescribeAccountLimits API. For information about updating this limit, see Amazon EC2 Auto Scaling service quotas in the Amazon EC2 Auto Scaling User Guide.
For more information, see Launch configurations in the Amazon EC2 Auto Scaling User Guide.

public CreateOrUpdateTagsResult createOrUpdateTags(CreateOrUpdateTagsRequest request)
AmazonAutoScaling
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 in the Amazon EC2 Auto Scaling User Guide.
createOrUpdateTags
in interface AmazonAutoScaling
public DeleteAutoScalingGroupResult deleteAutoScalingGroup(DeleteAutoScalingGroupRequest request)
AmazonAutoScaling
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 the DetachInstances API 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 the UpdateAutoScalingGroup API and set the minimum size and desired capacity of the Auto Scaling group to zero.
deleteAutoScalingGroup
in interface AmazonAutoScaling
public DeleteLaunchConfigurationResult deleteLaunchConfiguration(DeleteLaunchConfigurationRequest request)

If you choose not to decrement the desired capacity of the Auto Scaling group, the Auto Scaling group launches new instances to replace the instances on standby.
For more information, see Temporarily removing instances from your Auto Scaling group in the Amazon EC2 Auto Scaling User Guide.

public PutLifecycleHookResult putLifecycleHook(PutLifecycleHookRequest request)
AmazonAutoScaling
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 the RecordLifecycleActionHeartbeat API call.
If you finish before the timeout period ends, complete the lifecycle action using the CompleteLifecycleAction API call.
For more information, see Amazon EC2 Auto Scaling lifecycle hooks 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 the DescribeLifecycleHooks API call. If you are no longer using a lifecycle hook, you can delete it by calling the DeleteLifecycleHook API.

public PutNotificationConfigurationResult putNotificationConfiguration(PutNotificationConfigurationRequest request)
AmazonAutoScaling
Configures an Auto Scaling group to send notifications when specified events take place. Subscribers to the specified topic can have messages delivered to an endpoint such as a web server or an email address.
This configuration overwrites any existing configuration.
For more information, see Getting Amazon SNS notifications when your Auto Scaling group scales in the Amazon EC2 Auto Scaling User Guide.
If you exceed your maximum limit of SNS topics, which is 10 per Auto Scaling group, the call fails.

public PutScheduledUpdateGroupActionResult putScheduledUpdateGroupAction(PutScheduledUpdateGroupActionRequest request)
AmazonAutoScaling
Creates or updates a scheduled scaling action for an Auto Scaling group. If you leave a parameter unspecified when updating a scheduled scaling action, the corresponding value remains unchanged.
For more information, see Scheduled scaling in the Amazon EC2 Auto Scaling User Guide.
putScheduledUpdateGroupAction
in interface AmazonAutoScaling
public RecordLifecycleActionHeartbeatResult recordLifecycleActionHeartbeat(RecordLifecycleActionHeartbeatRequest request)
AmazonAutoScaling
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 the PutLifecycleHook API call.
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.

public SetDesiredCapacityResult setDesiredCapacity(SetDesiredCapacityRequest request)
AmazonAutoScaling
Sets the size of the specified Auto Scaling group.
If a scale-in activity 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.
For more information, see Manual scaling in the Amazon EC2 Auto Scaling User Guide.

public SetInstanceProtectionResult setInstanceProtection(SetInstanceProtectionRequest request)
AmazonAutoScaling
Updates the instance protection settings of the specified instances.
For more information about preventing instances that are part of an Auto Scaling group from terminating on scale in, see Instance scale-in protection in the Amazon EC2 Auto Scaling User Guide.
If you exceed your maximum limit of instance IDs, which is 50 per Auto Scaling group, the call fails.
setInstanceProtection
in interface AmazonAutoScaling
public StartInstanceRefreshResult startInstanceRefresh(StartInstanceRefreshRequest request)
AmazonAutoScaling
Starts a new instance refresh operation, which triggers a rolling replacement of all previously launched instances in the Auto Scaling group with a new group of instances.
If successful, this call creates a new instance refresh request with a unique ID that you can use to track its progress. To query its status, call the DescribeInstanceRefreshes API. To describe the instance refreshes that have already run, call the DescribeInstanceRefreshes API. To cancel an instance refresh operation in progress, use the CancelInstanceRefresh API.
For more information, see Replacing Auto Scaling Instances Based on an Instance Refresh.

public SuspendProcessesResult suspendProcesses(SuspendProcessesRequest request)
AmazonAutoScaling
Suspends the specified auto 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. For more information, see Suspending and
resuming scaling processes in the Amazon EC2 Auto Scaling User Guide.
To resume processes that have been suspended, call the ResumeProcesses API.
suspendProcesses
in interface AmazonAutoScaling
public TerminateInstanceInAutoScalingGroupResult terminateInstanceInAutoScalingGroup(TerminateInstanceInAutoScalingGroupRequest request)
AmazonAutoScaling
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 in the Amazon EC2 Auto Scaling User Guide.
terminateInstanceInAutoScalingGroup
in interface AmazonAutoScaling
public UpdateAutoScalingGroupResult updateAutoScalingGroup(UpdateAutoScalingGroupRequest request)
AmazonAutoScaling
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 activity 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, call the DescribeAutoScalingGroups API. To view the scaling policies for an Auto Scaling group, call the DescribePolicies API. If the group has scaling policies, you can update them by calling the PutScalingPolicy API.
