  • Method Details

    • minHealthyPercentage

      RefreshPreferences.Builder minHealthyPercentage(Integer minHealthyPercentage)

      Specifies the minimum percentage of the group to keep in service, healthy, and ready to use to support your workload to allow the operation to continue. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 0 to 100.

      If you do not specify this property, the default is 90 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.

      Parameters:
      minHealthyPercentage - Specifies the minimum percentage of the group to keep in service, healthy, and ready to use to support your workload to allow the operation to continue. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 0 to 100.

      If you do not specify this property, the default is 90 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.

      Returns:
      Returns a reference to this object so that method calls can be chained together.

    • instanceWarmup

      RefreshPreferences.Builder instanceWarmup(Integer instanceWarmup)

      A time period, in seconds, during which an instance refresh waits before moving on to replacing the next instance after a new instance enters the InService state.

      This property is not required for normal usage. Instead, use the DefaultInstanceWarmup property of the Auto Scaling group. The InstanceWarmup and DefaultInstanceWarmup properties work the same way. Only specify this property if you must override the DefaultInstanceWarmup property.

      If you do not specify this property, the instance warmup by default is the value of the DefaultInstanceWarmup property, if defined (which is recommended in all cases), or the HealthCheckGracePeriod property otherwise.

      Parameters:
      instanceWarmup - A time period, in seconds, during which an instance refresh waits before moving on to replacing the next instance after a new instance enters the InService state.

      This property is not required for normal usage. Instead, use the DefaultInstanceWarmup property of the Auto Scaling group. The InstanceWarmup and DefaultInstanceWarmup properties work the same way. Only specify this property if you must override the DefaultInstanceWarmup property.

      If you do not specify this property, the instance warmup by default is the value of the DefaultInstanceWarmup property, if defined (which is recommended in all cases), or the HealthCheckGracePeriod property otherwise.

      Returns:
      Returns a reference to this object so that method calls can be chained together.

      For usage examples, see Adding checkpoints to an instance refresh in the Amazon EC2 Auto Scaling User Guide.

      Parameters:
      checkpointPercentages - (Optional) Threshold values for each checkpoint in ascending order. Each number must be unique. To replace all instances in the Auto Scaling group, the last number in the array must be 100 .

    • skipMatching

      RefreshPreferences.Builder skipMatching(Boolean skipMatching)

      (Optional) Indicates whether skip matching is enabled. If enabled (true), then Amazon EC2 Auto Scaling skips replacing instances that match the desired configuration.

The default is false.

      For more information, see Use an instance refresh with skip matching in the Amazon EC2 Auto Scaling User Guide.

      Parameters:
      skipMatching - (Optional) Indicates whether skip matching is enabled. If enabled (true), then Amazon EC2 Auto Scaling skips replacing instances that match the desired configuration. If no desired configuration is specified, then it skips replacing instances that have the same launch template and instance types that the Auto Scaling group was using before the start of the instance refresh. The default is false.

    • autoRollback

      RefreshPreferences.Builder autoRollback(Boolean autoRollback)

      (Optional) Indicates whether to roll back the Auto Scaling group to its previous configuration if the instance refresh fails or a CloudWatch alarm threshold is met. The default is false.

      A rollback is not supported in the following situations:

      • There is no desired configuration specified for the instance refresh.

      • The Auto Scaling group has a launch template that uses an Amazon Web Services Systems Manager parameter instead of an AMI ID for the ImageId property.

      • The Auto Scaling group uses the launch template's $Latest or $Default version.

      For more information, see Undo changes with a rollback in the Amazon EC2 Auto Scaling User Guide.

      Parameters:
      autoRollback - (Optional) Indicates whether to roll back the Auto Scaling group to its previous configuration if the instance refresh fails or a CloudWatch alarm threshold is met. The default is false.

      A rollback is not supported in the following situations:

      • There is no desired configuration specified for the instance refresh.

      • The Auto Scaling group has a launch template that uses an Amazon Web Services Systems Manager parameter instead of an AMI ID for the ImageId property.

    • maxHealthyPercentage

      RefreshPreferences.Builder maxHealthyPercentage(Integer maxHealthyPercentage)

      Specifies the maximum percentage of the group that can be in service and healthy, or pending, to support your workload when replacing instances. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 100 to 200.

      If you specify MaxHealthyPercentage, you must also specify MinHealthyPercentage, and the difference between them cannot be greater than 100. A larger range increases the number of instances that can be replaced at the same time.

      If you do not specify this property, the default is 100 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.

      Parameters:
      maxHealthyPercentage - Specifies the maximum percentage of the group that can be in service and healthy, or pending, to support your workload when replacing instances. The value is expressed as a percentage of the desired capacity of the Auto Scaling group. Value range is 100 to 200.

      If you specify MaxHealthyPercentage, you must also specify MinHealthyPercentage, and the difference between them cannot be greater than 100. A larger range increases the number of instances that can be replaced at the same time.

      If you do not specify this property, the default is 100 percent, or the percentage set in the instance maintenance policy for the Auto Scaling group, if defined.
