AWS Infrastructure Example

A complete example of deploying AWS infrastructure using tfts.

This example demonstrates how to create a basic AWS infrastructure including a VPC, subnet, security group, and an EC2 instance. It also shows how to configure an S3 backend for state management.

Prerequisites

Ensure you have the AWS provider generated in your project:

npx tfts get

Complete Example

import { App, Stack, S3Backend } from "tfts";
import { AwsProvider } from "./.gen/providers/aws/provider";
import { Vpc } from "./.gen/providers/aws/vpc";
import { Subnet } from "./.gen/providers/aws/subnet";
import { SecurityGroup } from "./.gen/providers/aws/security-group";
import { Instance } from "./.gen/providers/aws/instance";

class MyAwsStack extends Stack {
  constructor(scope: App, id: string) {
    super(scope, id);

    // Configure the AWS Provider
    new AwsProvider(this, "aws", {
      region: "us-west-2",
    });

    // Configure S3 Backend
    new S3Backend(this, {
      bucket: "my-terraform-state-bucket",
      key: "network/terraform.tfstate",
      region: "us-west-2",
    });

    // Create a VPC
    const vpc = new Vpc(this, "main-vpc", {
      cidrBlock: "10.0.0.0/16",
      enableDnsHostnames: true,
      tags: {
        Name: "main-vpc",
      },
    });

    // Create a Subnet
    const subnet = new Subnet(this, "main-subnet", {
      vpcId: vpc.id,
      cidrBlock: "10.0.1.0/24",
      availabilityZone: "us-west-2a",
      tags: {
        Name: "main-subnet",
      },
    });

    // Create a Security Group
    const sg = new SecurityGroup(this, "web-sg", {
      vpcId: vpc.id,
      ingress: [
        {
          fromPort: 80,
          toPort: 80,
          protocol: "tcp",
          cidrBlocks: ["0.0.0.0/0"],
        },
        {
          fromPort: 22,
          toPort: 22,
          protocol: "tcp",
          cidrBlocks: ["0.0.0.0/0"],
        },
      ],
      egress: [
        {
          fromPort: 0,
          toPort: 0,
          protocol: "-1",
          cidrBlocks: ["0.0.0.0/0"],
        },
      ],
    });

    // Create an EC2 Instance
    new Instance(this, "web-server", {
      ami: "ami-0c55b159cbfafe1f0", // Amazon Linux 2
      instanceType: "t3.micro",
      subnetId: subnet.id,
      vpcSecurityGroupIds: [sg.id],
      tags: {
        Name: "web-server",
      },
    });
  }
}

const app = new App();
new MyAwsStack(app, "aws-example");
app.synth();

Key Concepts

• Provider Configuration: The AwsProvider construct initializes the connection to AWS.
• Backend Configuration: S3Backend tells Terraform to store the state file in an S3 bucket.
• Resource Referencing: Notice how subnet.id and sg.id are used to link resources together. tfts handles the underlying Terraform references automatically.
• Tags: Most AWS resources support a tags property for organization and cost tracking.
