cdktf-python-aws-ec2

The Cloud Development Kit for Terraform (CDKTF) allows you to define your infrastructure in a familiar programming language such as TypeScript, Python, Go, C#, or Java.

In this tutorial, you will provision an EC2 instance on AWS using your preferred programming language.

Prerequisites

• Terraform >= v1.0
• CDK for Terraform >= v0.8
• A Terraform Cloud account, with CLI authentication configured
• an AWS account
• AWS Credentials configured for use with Terraform

Credentials can be provided by using the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, and optionally AWS_SESSION_TOKEN environment variables. The region can be set using the AWS_REGION or AWS_DEFAULT_REGION environment variables.

$ export AWS_ACCESS_KEY_ID="anaccesskey"
$ export AWS_SECRET_ACCESS_KEY="asecretkey"
$ export AWS_REGION="us-west-2"

Install project dependencies

mkdir learn-cdktf
cd learn-cdktf
cdktf init --template="python"

Install AWS provider

pipenv install cdktf-cdktf-provider-aws

Define your CDK for Terraform Application

Replace the contents of main.py with the following code for a new Python application

#!/usr/bin/env python
from constructs import Construct
from cdktf import App, NamedRemoteWorkspace, TerraformStack, TerraformOutput, RemoteBackend
from cdktf_cdktf_provider_aws import AwsProvider, ec2


class MyStack(TerraformStack):
    def __init__(self, scope: Construct, ns: str):
        super().__init__(scope, ns)

        AwsProvider(self, "AWS", region="us-west-1")

        instance = ec2.Instance(self, "compute",
                                ami="ami-01456a894f71116f2",
                                instance_type="t2.micro",
                                )

        TerraformOutput(self, "public_ip",
                        value=instance.public_ip,
                        )


app = App()
stack = MyStack(app, "aws_instance")

RemoteBackend(stack,
              hostname='app.terraform.io',
              organization='<YOUR_ORG>',
              workspaces=NamedRemoteWorkspace('learn-cdktf')
              )

app.synth()

Provision infrastructure

cdktf deploy

After the instance is created, visit the AWS EC2 Dashboard.

Clean up your infrastructure

cdktf destroy
