or
npm install cdk-ec2spot@latest

// for CDKv1
npm install cdk-ec2spot@cdkv1 

Sample

import * as ec2spot from 'cdk-ec2spot';

// create a ec2spot provider
const provider = new ec2spot.Provider(stack, 'Provider');

// import or create a vpc
const vpc = provider.getOrCreateVpc(stack);

// create an AutoScalingGroup with Launch Template for spot instances
provider.createAutoScalingGroup('SpotASG', {
  vpc,
  defaultCapacitySize: 2,
  instanceType: new ec2.InstanceType('m5.large'),
});

EC2 Spot Fleet support

In addition to EC2 AutoScaling Group, you may use createFleet() to create an EC2 Spot Fleet:

provider.createFleet('SpotFleet', {
  vpc,
  defaultCapacitySize: 2,
  instanceType: new ec2.InstanceType('t3.large'),
});

Single Spot Instnce

If you just need single spot instance without any autoscaling group or spot fleet, use createInstance():

provider.createInstance('SpotInstance', { vpc })
