Deploy a Web Application on Amazon EC2


Module 3: Deploy CDK Stack

In this module, you will deploy your infrastructure and application.


With the AWS CDK app created, resources defined, and a user data asset for installing software on first launch, you are ready to deploy your stack and create the resources. In this module, you will deploy the stack using CDK.

What You Will Learn

  • Bootstrap CDK
  • Deploy all the infrastructure using CDK

 Time to Complete

5 minutes

 Module Prereqs

  • AWS Account with administrator-level access**
  • Recommended browser: The latest version of Chrome or Firefox

[**]Accounts created within the past 24 hours might not yet have access to the services required for this tutorial.


Bootstrap CDK

Before you can deploy your CDK app, you need to set up CDK on the account you are deploying to. Edit the bin/cdk-ecs-infra.ts file, and uncomment line 14:

env: { account: process.env.CDK_DEFAULT_ACCOUNT, region: process.env.CDK_DEFAULT_REGION },

This will use the Account ID and region configured in the AWS CLI. Before you can use CDK, it needs to be bootstrapped - this will create the required infrastructure for CDK to manage infrastructure in your account. To bootstrap CDK, run cdk bootstrap

You should see output similar to:

cdk bootstrap

⏳  Bootstrapping environment aws://0123456789012/<region>...
✅  Environment aws://0123456789012/<region> bootstrapped

Deploying the stack

Once the bootstrapping has completed, you will run cdk deploy to deploy all the infrastructure you created. You will be presented with the following output, and confirmation screen.

As our stack has security implications, you'll see a summary of these and need to confirm them before deployment proceeds.


Enter y to continue with the deployment and create the resources. The CLI will show the deployment progress and in the end the output we defined in our CDK app.

✅  Ec2CdkStack

Ec2CdkStack.DownloadKeyCommand = aws secretsmanager get-secret-value --secret-id ec2-ssh-key/cdk-keypair/private --query SecretString --output text > cdk-key.pem && chmod 400 cdk-key.pem
Ec2CdkStack.IPAddress =
Ec2CdkStack.sshcommand = ssh -i cdk-key.pem -o IdentitiesOnly=yes ec2-user@

Stack ARN:

Your application is now deployed, and you can use the outputs at the bottom to download the SSH key, and then access the EC2 instance if you need to. You can also access the application in your browser by pasting in the IP printed above.


In this module, you learned how to bootstrap CDK to your account, and use it to deploy your infrastructure and web application. In the next module, you will clean up all the resources created in this guide.
