Method Detail

scalingAdjustment

@Stability(value=Stable)
public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder scalingAdjustment(Number scalingAdjustment)

Sets the value of CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.getScalingAdjustment()

Parameters:

scalingAdjustment - The amount by which to scale in or scale out, based on the specified `AdjustmentType` . This parameter is required. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY , the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY , the value should express the percentage as an integer. For example, -20 indicates a decrease in 20% increments of cluster capacity.

Returns:

this

adjustmentType

@Stability(value=Stable)
public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder adjustmentType(String adjustmentType)

Sets the value of CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.getAdjustmentType()

Parameters:

adjustmentType - The way in which EC2 instances are added (if `ScalingAdjustment` is a positive number) or terminated (if `ScalingAdjustment` is a negative number) each time the scaling activity is triggered. CHANGE_IN_CAPACITY is the default. CHANGE_IN_CAPACITY indicates that the EC2 instance count increments or decrements by ScalingAdjustment , which should be expressed as an integer. PERCENT_CHANGE_IN_CAPACITY indicates the instance count increments or decrements by the percentage specified by ScalingAdjustment , which should be expressed as an integer. For example, 20 indicates an increase in 20% increments of cluster capacity. EXACT_CAPACITY indicates the scaling activity results in an instance group with the number of EC2 instances specified by ScalingAdjustment , which should be expressed as a positive integer.

Returns:

this

coolDown

@Stability(value=Stable)
public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.Builder coolDown(Number coolDown)

Sets the value of CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty.getCoolDown()

Parameters:

coolDown - The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.

Returns:

this

build

@Stability(value=Stable)
public CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty build()

Builds the configured instance.

Specified by:

build in interface software.amazon.jsii.Builder<CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty>

Returns:

a new instance of CfnInstanceGroupConfig.SimpleScalingPolicyConfigurationProperty

Throws:

NullPointerException - if any required attribute was not provided
