Method Detail
-
setEndpoint
void setEndpoint(String endpoint)
Overrides the default endpoint for this client ("https://autoscaling.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.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: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
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.
- Parameters:
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.
-
setRegion
void setRegion(Region region)
An alternative tosetEndpoint(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.
- Parameters:
region
- The region this client will communicate with. SeeRegion.getRegion(com.amazonaws.regions.Regions)
for accessing a given region. Must not be null and must be a region where the service is available.- See Also:
Region.getRegion(com.amazonaws.regions.Regions)
,Region.createClient(Class, com.amazonaws.auth.AWSCredentialsProvider, ClientConfiguration)
,Region.isServiceSupported(String)
-
attachInstances
AttachInstancesResult 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.
- Parameters:
attachInstancesRequest
-- Returns:
- Result of the AttachInstances 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

-
completeLifecycleAction
CompleteLifecycleActionResult completeLifecycleAction(CompleteLifecycleActionRequest completeLifecycleActionRequest)
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 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 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 Auto Scaling Lifecycle in the Auto Scaling Developer Guide.
- Parameters:
completeLifecycleActionRequest

putLifecycleHook
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 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 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 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 Auto Scaling Lifecycle 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.
- Parameters:
putLifecycleHookRequest
-- Returns:
- Result of the PutLifecycleHook operation returned by the service.
- Throws:
LimitExceededException

-
getCachedResponseMetadata
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 a request.
- Parameters:
request
- The originally executed request.- Returns:
- The response metadata for the specified request, or null if none is available.
