Method Details

maxSize

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder maxSize(String maxSize)

Sets the value of CfnAutoScalingGroupProps.getMaxSize()

Parameters:

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

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).

Returns:

this

minSize

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder minSize(String minSize)

Sets the value of CfnAutoScalingGroupProps.getMinSize()

Parameters:

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

Returns:

this

autoScalingGroupName

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder autoScalingGroupName(String autoScalingGroupName)

Sets the value of CfnAutoScalingGroupProps.getAutoScalingGroupName()

Parameters:

autoScalingGroupName - The name of the Auto Scaling group. This name must be unique per Region per account. The name can contain any ASCII character 33 to 126 including most punctuation characters, digits, and upper and lowercased letters.

You cannot use a colon (:) in the name.

Returns:

this

availabilityZones

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder availabilityZones(List<String> availabilityZones)

Sets the value of CfnAutoScalingGroupProps.getAvailabilityZones()

Parameters:

availabilityZones - A list of Availability Zones where instances in the Auto Scaling group can be created. Used for launching into the default VPC subnet in each Availability Zone when not using the VPCZoneIdentifier property, or for attaching a network interface when an existing network interface ID is specified in a launch template.

Returns:

this

capacityRebalance

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder capacityRebalance(Boolean capacityRebalance)

Sets the value of CfnAutoScalingGroupProps.getCapacityRebalance()

Parameters:

capacityRebalance - Indicates whether Capacity Rebalancing is enabled. Otherwise, Capacity Rebalancing is disabled. When you turn on Capacity Rebalancing, Amazon EC2 Auto Scaling attempts to launch a Spot Instance whenever Amazon EC2 notifies that a Spot Instance is at an elevated risk of interruption. After launching a new instance, it then terminates an old instance. For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the in the Amazon EC2 Auto Scaling User Guide .

Returns:

this

capacityRebalance

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder capacityRebalance(IResolvable capacityRebalance)

Sets the value of CfnAutoScalingGroupProps.getCapacityRebalance()

Parameters:

capacityRebalance - Indicates whether Capacity Rebalancing is enabled. Otherwise, Capacity Rebalancing is disabled. When you turn on Capacity Rebalancing, Amazon EC2 Auto Scaling attempts to launch a Spot Instance whenever Amazon EC2 notifies that a Spot Instance is at an elevated risk of interruption. After launching a new instance, it then terminates an old instance. For more information, see Use Capacity Rebalancing to handle Amazon EC2 Spot Interruptions in the in the Amazon EC2 Auto Scaling User Guide .

Returns:

this

context

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder context(String context)

Sets the value of CfnAutoScalingGroupProps.getContext()

Parameters:

context - Reserved.

Returns:

this

cooldown

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder cooldown(String cooldown)

Sets the value of CfnAutoScalingGroupProps.getCooldown()

Parameters:

cooldown - Only needed if you use simple scaling policies.. The amount of time, in seconds, between one scaling activity ending and another one starting due to simple scaling policies. For more information, see Scaling cooldowns for Amazon EC2 Auto Scaling in the Amazon EC2 Auto Scaling User Guide .

Default: 300 seconds

Returns:

this

defaultInstanceWarmup

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder defaultInstanceWarmup(Number defaultInstanceWarmup)

Sets the value of CfnAutoScalingGroupProps.getDefaultInstanceWarmup()

Parameters:

defaultInstanceWarmup - The amount of time, in seconds, until a new instance is considered to have finished initializing and resource consumption to become stable after it enters the InService state. During an instance refresh, Amazon EC2 Auto Scaling waits for the warm-up period after it replaces an instance before it moves on to replacing the next instance. Amazon EC2 Auto Scaling also waits for the warm-up period before aggregating the metrics for new instances with existing instances in the Amazon CloudWatch metrics that are used for scaling, resulting in more reliable usage data. For more information, see Set the default instance warmup for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide .

To manage various warm-up settings at the group level, we recommend that you set the default instance warmup, even if it is set to 0 seconds . To remove a value that you previously set, include the property but specify -1 for the value. However, we strongly recommend keeping the default instance warmup enabled by specifying a value of 0 or other nominal value.

Default: None

Returns:

this

desiredCapacity

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder desiredCapacity(String desiredCapacity)

Sets the value of CfnAutoScalingGroupProps.getDesiredCapacity()

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. 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.

Returns:

this

desiredCapacityType

@Stability(Stable)
public CfnAutoScalingGroupProps.Builder desiredCapacityType(String desiredCapacityType)

Sets the value of CfnAutoScalingGroupProps.getDesiredCapacityType()

Parameters:

desiredCapacityType - The unit of measurement for the value specified for desired capacity. Amazon EC2 Auto Scaling supports DesiredCapacityType for attribute-based instance type selection only. For more information, see Creating an Auto Scaling group using attribute-based instance type selection in the Amazon EC2 Auto Scaling User Guide .

Parameters:

healthCheckGracePeriod - The amount of time, in seconds, that Amazon EC2 Auto Scaling waits before checking the health status of an EC2 instance that has come into service and marking it unhealthy due to a failed health check. This is useful if your instances do not immediately pass their health checks after they enter the InService state. For more information, see Set the health check grace period for an Auto Scaling group in the Amazon EC2 Auto Scaling User Guide .

Default: 0 seconds

Returns:

this
