@aws-cdk/aws-autoscaling
Advanced tools
This module is part of the AWS Cloud Development Kit project.
An AutoScalingGroup represents a number of instances on which you run your code. You
pick the size of the fleet, the instance type and the OS image:
import autoscaling = require('@aws-cdk/aws-autoscaling');
import ec2 = require('@aws-cdk/aws-ec2');
new autoscaling.AutoScalingGroup(stack, 'ASG', {
vpc,
instanceType: new ec2.InstanceTypePair(InstanceClass.Burstable2, InstanceSize.Micro),
machineImage: new ec2.AmazonLinuxImage() // get the latest Amazon Linux image
});
NOTE: AutoScalingGroup has an property called
allowAllOutbound(allowing the instances to contact the internet) which is set totrueby default. Be sure to set this tofalseif you don't want your instances to be able to start arbitrary connections.
AMIs control the OS that gets launched when you start your EC2 instance. The EC2 library contains constructs to select the AMI you want to use.
Depending on the type of AMI, you select it a different way.
The latest version of Amazon Linux and Microsoft Windows images are selectable by instantiating one of these classes:
NOTE: The Amazon Linux images selected will be cached in your
cdk.json, so that your AutoScalingGroups don't automatically change out from under you when you're making unrelated changes. To update to the latest version of Amazon Linux, remove the cache entry from thecontextsection of yourcdk.json.We will add command-line options to make this step easier in the future.
See the documentation of the aws-ec2 package for more information about allowing connections between resources backed by instances.
