# `cdk-ec2spot`
CDK construct library that allows you to create EC2 Spot instances with `AWS AutoScaling Group`, `Spot Fleet` or just single `Spot Instance`.
# Install
Use the npm dist tag to opt in CDKv1 or CDKv2:
```sh
// for CDKv2
npm install cdk-ec2spot
or
npm install cdk-ec2spot@latest
// for CDKv1
npm install cdk-ec2spot@cdkv1
```
# Sample
```python
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:
```python
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()`:
```python
provider.createInstance('SpotInstance', { vpc })
```
