Usage

Install project dependencies

yarn install

Generate CDK for Terraform constructs for Terraform provides and modules used in the project.

cdktf get

You can now edit the main.ts file if you want to modify any code.

vim main.ts
import { Construct } from 'constructs';
import { App, TerraformStack, Token } from 'cdktf';
import { Eks } from './.gen/modules/terraform-aws-modules/eks/aws';
import { Vpc } from './.gen/modules/terraform-aws-modules/vpc/aws';
import { DynamodbTable } from './.gen/providers/aws/dynamodb-table';
import { SnsTopic } from './.gen/providers/aws/sns-topic';
import { AwsProvider } from './.gen/providers/aws'

export class HelloTerra extends TerraformStack {
  constructor(scope: Construct, id: string) {
    super(scope, id);

    new AwsProvider(this, 'aws', {
      region: 'eu-central-1'
    })

    const table = new DynamodbTable(this, 'Hello', {
      name: 'my-first-table',
      hashKey: 'temp',
      attribute: [
        { name: 'id', type: 'S' }
      ]
    });

    table.addOverride('hash_key', 'id')
    table.addOverride('lifecycle', { create_before_destroy: true })

    new SnsTopic(this, 'Topic', {
      displayName: 'my-first-sns-topic'
    });

    const vpcName = 'MyVpc';
    const vpc = new Vpc(this, vpcName, {
      name: vpcName,
      cidr: "10.0.0.0/16",
      azs: ["us-east-1a", "us-east-1b"],
      publicSubnets: ["10.0.1.0/24", "10.0.2.0/24"]
    });

    new Eks(this, 'EksModule', {
      clusterName: 'myClusterName',
      permissionsBoundary: 'boom',
      vpcId: vpc.vpcIdOutput,
      subnets: Token.asList(vpc.publicSubnetsOutput)
    });

    this.addOverride('terraform.backend', {
      remote: {
        organization: 'test',
        workspaces: {
          name: 'test'
        }
      }
    });
  }
}

const app = new App();
new HelloTerra(app, 'hello-terra');
app.synth();

Compile the TypeScript application

tsc

Generate Terraform configuration

cdktf synth

The above command will create a folder called cdktf.out that contains all Terraform JSON configuration that was generated.

Run Terraform commands

cd cdktf.out
terraform init
terraform plan
terraform apply
