@Stability(value=Stable)
public static CfnAutoScalingGroup.Builder create(software.constructs.Construct scope,
                                                                          String id)

Returns:

a new instance of CfnAutoScalingGroup.AcceleratorCountRequestProperty.Builder.

maxSize

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder maxSize(String maxSize)

The maximum size of the group.

With a mixed instances policy that uses instance weighting, Amazon EC2 Auto Scaling may need to go above MaxSize to meet your capacity requirements. In this event, Amazon EC2 Auto Scaling will never go above MaxSize by more than your largest instance weight (weights that define how many units each instance contributes to the desired capacity of the group).

Parameters:

maxSize - The maximum size of the group. This parameter is required.

Returns:

this

minSize

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder minSize(String minSize)

The minimum size of the group.

Parameters:

minSize - The minimum size of the group. This parameter is required.

Returns:

this

autoScalingGroupName

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder autoScalingGroupName(String autoScalingGroupName)

The name of the Auto Scaling group.

This name must be unique per Region per account.

Parameters:

autoScalingGroupName - The name of the Auto Scaling group. This parameter is required.

Returns:

this

availabilityZones

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder availabilityZones(List<String> availabilityZones)

A list of Availability Zones where instances in the Auto Scaling group can be created.

You must specify one of the following properties: VPCZoneIdentifier or AvailabilityZones . If your account supports EC2-Classic and VPC, this property is required to create an Auto Scaling group that launches instances into EC2-Classic.

Parameters:

availabilityZones - A list of Availability Zones where instances in the Auto Scaling group can be created. This parameter is required.

Returns:

this

capacityRebalance

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder capacityRebalance(Boolean capacityRebalance)

Indicates whether Capacity Rebalancing is enabled.

For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the Amazon EC2 Auto Scaling User Guide .

Parameters:

capacityRebalance - Indicates whether Capacity Rebalancing is enabled. This parameter is required.

Returns:

this

capacityRebalance

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder capacityRebalance(IResolvable capacityRebalance)

Indicates whether Capacity Rebalancing is enabled.

For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the Amazon EC2 Auto Scaling User Guide .

Parameters:

capacityRebalance - Indicates whether Capacity Rebalancing is enabled. This parameter is required.

Returns:

this

context

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder context(String context)

Reserved.

Parameters:

context - Reserved. This parameter is required.

Returns:

this

cooldown

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder cooldown(String cooldown)

The amount of time, in seconds, after a scaling activity completes before another scaling activity can start.

The default value is 300 . This setting applies when using simple scaling policies, but not when using other scaling policies or scheduled scaling. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide .

Parameters:

cooldown - The amount of time, in seconds, after a scaling activity completes before another scaling activity can start. This parameter is required.

Returns:

this

desiredCapacity

@Stability(value=Stable)
public CfnAutoScalingGroup.Builder desiredCapacity(String desiredCapacity)

The desired capacity is the initial capacity of the Auto Scaling group at the time of its creation and the capacity it attempts to maintain.

It can scale beyond this capacity if you configure automatic scaling.

The number must be greater than or equal to the minimum size of the group and less than or equal to the maximum size of the group. If you do not specify a desired capacity when creating the stack, the default is the minimum size of the group.

CloudFormation marks the Auto Scaling group as successful (by setting its status to CREATE_COMPLETE) when the desired capacity is reached. However, if a maximum Spot price is set in the launch template or launch configuration that you specified, then desired capacity is not used as a criteria for success. Whether your request is fulfilled depends on Spot Instance capacity and your maximum price.

Parameters:

desiredCapacity - The desired capacity is the initial capacity of the Auto Scaling group at the time of its creation and the capacity it attempts to maintain. This parameter is required.

Returns:

this

By default, Amazon EC2 Auto Scaling specifies units , which translates into number of instances.

Valid values: units | vcpu | memory-mib

Parameters:

desiredCapacityType - The unit of measurement for the value specified for desired capacity. This parameter is required.

Returns:

this
