Method Detail

attachInstances

public void attachInstances(AttachInstancesRequest attachInstancesRequest)

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

When you attach instances, 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.

For more information, see Attach EC2 Instances to Your Auto Scaling Group in the Auto Scaling Developer Guide.

Specified by:

attachInstances in interface AmazonAutoScaling

Parameters:

attachInstancesRequest -

Throws:

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

attachLoadBalancers

public AttachLoadBalancersResult attachLoadBalancers(AttachLoadBalancersRequest attachLoadBalancersRequest)

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.

Specified by:

attachLoadBalancers in interface AmazonAutoScaling

Parameters:

attachLoadBalancersRequest -

Returns:

Result of the AttachLoadBalancers operation returned by the service.

Throws:

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

attachLoadBalancers

public AttachLoadBalancersResult attachLoadBalancers()

Description copied from interface: AmazonAutoScaling

Simplified method form for invoking the AttachLoadBalancers operation.

Specified by:

attachLoadBalancers in interface AmazonAutoScaling

See Also:

AmazonAutoScaling.attachLoadBalancers(AttachLoadBalancersRequest)

completeLifecycleAction

public CompleteLifecycleActionResult completeLifecycleAction(CompleteLifecycleActionRequest completeLifecycleActionRequest)

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.

Specified by:

completeLifecycleAction in interface AmazonAutoScaling

Parameters:

completeLifecycleActionRequest -

Returns:

Result of the CompleteLifecycleAction operation returned by the service.

Throws:

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

createAutoScalingGroup

public void createAutoScalingGroup(CreateAutoScalingGroupRequest createAutoScalingGroupRequest)

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.

For more information, see Auto Scaling Groups in the Auto Scaling Developer Guide.

Specified by:

createAutoScalingGroup in interface AmazonAutoScaling

Parameters:

createAutoScalingGroupRequest -

Throws:

AlreadyExistsException - You already have an Auto Scaling group or launch configuration with this name.

LimitExceededException - You have already reached a limit for your Auto Scaling resources (for example, groups, launch configurations, or lifecycle hooks). For more information, see DescribeAccountLimits.

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

createLaunchConfiguration

public void createLaunchConfiguration(CreateLaunchConfigurationRequest createLaunchConfigurationRequest)

Creates a launch configuration.

If you exceed your maximum limit of launch configurations, which by default is 100 per region, the call fails. For information about viewing and updating this limit, see DescribeAccountLimits.

For more information, see Launch Configurations in the Auto Scaling Developer Guide.

Specified by:

createLaunchConfiguration in interface AmazonAutoScaling

Parameters:

createLaunchConfigurationRequest -

Throws:

AlreadyExistsException - You already have an Auto Scaling group or launch configuration with this name.

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

createOrUpdateTags

public void createOrUpdateTags(CreateOrUpdateTagsRequest createOrUpdateTagsRequest)

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.

Specified by:

createOrUpdateTags in interface AmazonAutoScaling

Parameters:

createOrUpdateTagsRequest -

Throws:

LimitExceededException - You have already reached a limit for your Auto Scaling resources (for example, groups, launch configurations, or lifecycle hooks). For more information, see DescribeAccountLimits.

AlreadyExistsException - You already have an Auto Scaling group or launch configuration with this name.

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

deleteAutoScalingGroup

public void deleteAutoScalingGroup(DeleteAutoScalingGroupRequest deleteAutoScalingGroupRequest)

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 so that 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.

putLifecycleHook

public PutLifecycleHookResult putLifecycleHook(PutLifecycleHookRequest putLifecycleHookRequest)

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.

Specified by:

putLifecycleHook in interface AmazonAutoScaling

Parameters:

putLifecycleHookRequest -

Returns:

Result of the PutLifecycleHook operation returned by the service.

Throws:

LimitExceededException - You have already reached a limit for your Auto Scaling resources (for example, groups, launch configurations, or lifecycle hooks). For more information, see DescribeAccountLimits.

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

putNotificationConfiguration

public void putNotificationConfiguration(PutNotificationConfigurationRequest putNotificationConfigurationRequest)

putScalingPolicy

public PutScalingPolicyResult putScalingPolicy(PutScalingPolicyRequest putScalingPolicyRequest)

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.

Specified by:

putScalingPolicy in interface AmazonAutoScaling

Parameters:

putScalingPolicyRequest -

Returns:

Result of the PutScalingPolicy operation returned by the service.

ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).

recordLifecycleActionHeartbeat

public RecordLifecycleActionHeartbeatResult recordLifecycleActionHeartbeat(RecordLifecycleActionHeartbeatRequest recordLifecycleActionHeartbeatRequest)

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.

getCachedResponseMetadata

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Specified by:

getCachedResponseMetadata in interface AmazonAutoScaling

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
