public interface AddCapacityOptions
extends AddAutoScalingGroupCapacityOptions, CommonAutoScalingGroupProps

The properties for adding instance capacity to an AutoScalingGroup.

Example:

 Vpc vpc;
 Cluster cluster = Cluster.Builder.create(this, "Cluster")
         .vpc(vpc)
         .build();
 // Either add default capacity
 cluster.addCapacity("DefaultAutoScalingGroupCapacity", AddCapacityOptions.builder()
         .instanceType(new InstanceType("t2.xlarge"))
         .desiredCapacity(3)
         .build());
 // Or add customized capacity. Be sure to start the Amazon ECS-optimized AMI.
 AutoScalingGroup autoScalingGroup = AutoScalingGroup.Builder.create(this, "ASG")
         .vpc(vpc)
         .instanceType(new InstanceType("t2.xlarge"))
         .machineImage(EcsOptimizedImage.amazonLinux())
         // Or use Amazon ECS-Optimized Amazon Linux 2 AMI
         // machineImage: EcsOptimizedImage.amazonLinux2(),
         .desiredCapacity(3)
         .build();
 cluster.addAutoScalingGroup(autoScalingGroup);

Method Detail

getInstanceType

InstanceType getInstanceType()

The EC2 instance type to use when launching instances into the AutoScalingGroup.

getMachineImage

default IMachineImage getMachineImage()

The ECS-optimized AMI variant to use.

The default is to use an ECS-optimized AMI of Amazon Linux 2 which is automatically updated to the latest version on every deployment. This will replace the instances in the AutoScalingGroup. Make sure you have not disabled task draining, to avoid downtime when the AMI updates.

To use an image that does not update on every deployment, pass:

 EcsOptimizedImage machineImage = EcsOptimizedImage.amazonLinux2(AmiHardwareType.STANDARD, EcsOptimizedImageOptions.builder()
         .cachedInContext(true)
         .build());
 

For more information, see Amazon ECS-optimized AMIs.

You must define either machineImage or machineImageType, not both.

Default: - Automatically updated, ECS-optimized Amazon Linux 2
