Interface AmazonAutoScaling

    • 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.
      • 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).
      • 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:

        1. (Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Auto Scaling launches or terminates instances.
        2. (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.
        3. Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
        4. If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
        5. 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 -
        Returns:
        Result of the CompleteLifecycleAction operation returned by the service.
        Throws:

      • 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:

        1. (Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Auto Scaling launches or terminates instances.
        2. (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.
        3. Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
        4. If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
        5. 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.

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

        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.

        Parameters:
        putScalingPolicyRequest -
        Returns:
        Result of the PutScalingPolicy 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).
      • putScheduledUpdateGroupAction

        PutScheduledUpdateGroupActionResult putScheduledUpdateGroupAction​(PutScheduledUpdateGroupActionRequest putScheduledUpdateGroupActionRequest)

        Creates or updates a scheduled scaling action for an Auto Scaling group. When updating a scheduled scaling action, if you leave a parameter unspecified, the corresponding value remains unchanged in the affected Auto Scaling group.

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

        Parameters:
        putScheduledUpdateGroupActionRequest -
        Returns:
        Result of the PutScheduledUpdateGroupAction operation returned by the service.
        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).
      • recordLifecycleActionHeartbeat

        RecordLifecycleActionHeartbeatResult recordLifecycleActionHeartbeat​(RecordLifecycleActionHeartbeatRequest recordLifecycleActionHeartbeatRequest)

        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:

        1. (Optional) Create a Lambda function and a rule that allows CloudWatch Events to invoke your Lambda function when Auto Scaling launches or terminates instances.
        2. (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.
        3. Create the lifecycle hook. Specify whether the hook is used when the instances launch or terminate.
        4. If you need more time, record the lifecycle action heartbeat to keep the instance in a pending state.
        5. 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:
        recordLifecycleActionHeartbeatRequest -
        Returns:
        Result of the RecordLifecycleActionHeartbeat 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).

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

        TerminateInstanceInAutoScalingGroupResult terminateInstanceInAutoScalingGroup​(TerminateInstanceInAutoScalingGroupRequest terminateInstanceInAutoScalingGroupRequest)

        Terminates the specified instance and optionally adjusts the desired group size.

        This call simply makes a termination request. The instance is not terminated immediately.

        Parameters:
        terminateInstanceInAutoScalingGroupRequest -
        Returns:
        Result of the TerminateInstanceInAutoScalingGroup operation returned by the service.
        Throws:
        ScalingActivityInProgressException - The Auto Scaling group can't be deleted because there are scaling activities in progress.

      • updateAutoScalingGroup

        UpdateAutoScalingGroupResult updateAutoScalingGroup​(UpdateAutoScalingGroupRequest updateAutoScalingGroupRequest)

        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.

        Parameters:
        updateAutoScalingGroupRequest -
        Returns:
        Result of the UpdateAutoScalingGroup operation returned by the service.
        Throws:
        ScalingActivityInProgressException - The Auto Scaling group can't be deleted because there are scaling activities in progress.
        ResourceContentionException - You already have a pending update to an Auto Scaling resource (for example, a group, instance, or load balancer).
      • shutdown

        void shutdown()
        Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
      • 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.
