Introduction to terraform CDK

What is TerraformđŸ€”?
What is Terraform CDK?
  • It supports TypeScript, Python, C#, Go(Beta), and Java Currently.
  • Getting started 😃
    Before we get started install cdktf-cli by running npm i -g cdktf-cli@latest and then run cdktf init to initialize a broiler code for you. Choose the language and name as your choice. For this instance, I will be using typescript.
    Let's add AWS providers and try to make an EC2 Instance. There are some prebuilt providers like the following for typescript. So in this case we install the AWS provider by running npm i @cdktf/provider-aws
    If in case you are using any other language then you can add your providers to the terraformProviders field in the cdktf.json file and run cdktf get to install the constructs and convert them to your native language
    {
    "language": "typescript",
    "app": "npm run --silent compile && node main.js",
    "projectId": "5632caca-2a91-436c-963d-57dccfa2d7b0",
    "terraformProviders": ["aws@~> 3.63"],
    "terraformModules": [],
    "context": {
    "excludeStackIdFromLogicalIds": "true",
    "allowSepCharsInLogicalIds": "true"
    }
    }

    Here's my Typescript Code
    import { Construct } from 'constructs';
    import { App, TerraformStack } from 'cdktf';
    import { AwsProvider, EC2 } from '@cdktf/provider-aws';
    class MyStack extends TerraformStack {
    constructor(scope: Construct, name: string) {
    super(scope, name);
    // define resources here
    new AwsProvider(this, 'aws', {
    region: 'us-east-1',
    accessKey: 'accessKey', // enter your access key here
    secretKey: 'secretKey', // enter your secret key here
    });
    new EC2.Instance(this, 'ec2', {
    instanceType: 't2.micro',
    ami: 'ami-0b9c9f1d',
    availabilityZone: 'us-east-1a',
    keyName: 'my-key-pair',
    });
    }
    }
    const app = new App({
    outdir: 'dist', // set output directory as your needs
    skipValidation: false, // set to true if you want to skip validation
    stackTraces: false, // set to true if you want to see stack traces
    });
    const stackName = 'my-stack'; // set stack name as your needs
    new MyStack(app, stackName);
    app.synth();

    Running cdktf synth will create a directory called cdktf.out where you will have your stack named folder which contains the terraform files.
    Now you can run terraform init & terraform plan to initialize terraform and review your infrastructure resources and if you want to go ahead and apply the changes run terraform apply
    Notes
  • You must have to terraform installed in order for cdktf to work. You can Download the latest version by visiting this link
  • If you guys want me write the same for other language do let me know in the comment section below
