Method Detail

getMaxBatchSize

@Stability(value=Stable)
 @Nullable
public Number getMaxBatchSize()

Specifies the maximum number of instances that AWS CloudFormation updates.

Specified by:

getMaxBatchSize in interface CfnAutoScalingRollingUpdate

getMinInstancesInService

@Stability(value=Stable)
 @Nullable
public Number getMinInstancesInService()

Specifies the minimum number of instances that must be in service within the Auto Scaling group while AWS CloudFormation updates old instances.

Specified by:

getMinInstancesInService in interface CfnAutoScalingRollingUpdate

getMinSuccessfulInstancesPercent

@Stability(value=Stable)
 @Nullable
public Number getMinSuccessfulInstancesPercent()

Specifies the percentage of instances in an Auto Scaling rolling update that must signal success for an update to succeed. You can specify a value from 0 to 100. AWS CloudFormation rounds to the nearest tenth of a percent. For example, if you update five instances with a minimum successful percentage of 50, three instances must signal success. If an instance doesn't send a signal within the time specified in the PauseTime property, AWS CloudFormation assumes that the instance wasn't updated. If you specify this property, you must also enable the WaitOnResourceSignals and PauseTime properties.

Specified by:

getMinSuccessfulInstancesPercent in interface CfnAutoScalingRollingUpdate

getPauseTime

@Stability(value=Stable)
 @Nullable
public String getPauseTime()

The amount of time that AWS CloudFormation pauses after making a change to a batch of instances to give those instances time to start software applications. For example, you might need to specify PauseTime when scaling up the number of instances in an Auto Scaling group. If you enable the WaitOnResourceSignals property, PauseTime is the amount of time that AWS CloudFormation should wait for the Auto Scaling group to receive the required number of valid signals from added or replaced instances. If the PauseTime is exceeded before the Auto Scaling group receives the required number of signals, the update fails. For best results, specify a time period that gives your applications sufficient time to get started. If the update needs to be rolled back, a short PauseTime can cause the rollback to fail. Specify PauseTime in the ISO8601 duration format (in the format PT#H#M#S, where each # is the number of hours, minutes, and seconds, respectively). The maximum PauseTime is one hour (PT1H).

Specified by:

getPauseTime in interface CfnAutoScalingRollingUpdate

getSuspendProcesses

@Stability(value=Stable)
 @Nullable
public List<String> getSuspendProcesses()

Specifies the Auto Scaling processes to suspend during a stack update. Suspending processes prevents Auto Scaling from interfering with a stack update. For example, you can suspend alarming so that Auto Scaling doesn't execute scaling policies associated with an alarm. For valid values, see the ScalingProcesses.member.N parameter for the SuspendProcesses action in the Auto Scaling API Reference.

Specified by:

getSuspendProcesses in interface CfnAutoScalingRollingUpdate

getWaitOnResourceSignals

@Stability(value=Stable)
 @Nullable
public Boolean getWaitOnResourceSignals()

Specifies whether the Auto Scaling group waits on signals from new instances during an update. Use this property to ensure that instances have completed installing and configuring applications before the Auto Scaling group update proceeds. AWS CloudFormation suspends the update of an Auto Scaling group after new EC2 instances are launched into the group. AWS CloudFormation must receive a signal from each new instance within the specified PauseTime before continuing the update. To signal the Auto Scaling group, use the cfn-signal helper script or SignalResource API. To have instances wait for an Elastic Load Balancing health check before they signal success, add a health-check verification by using the cfn-init helper script. For an example, see the verify_instance_health command in the Auto Scaling rolling updates sample template.
