AWS CDK in Practice

By: Mark Avdi, Leo Lam

Overview of this book

As cloud applications are becoming more complex, multiple tools and services have emerged to cater to the challenges of running reliable solutions. Although infrastructure as code, containers, and orchestration tools, such as Kubernetes, have proved to be efficient in solving these challenges, AWS CDK represents a paradigm shift in building easily developed, extended, and maintained applications. With AWS CDK in Practice, you’ll start by setting up basic day-to-day infrastructure while understanding the new prospects that CDK offers. You’ll learn how to set up pipelines for building CDK applications on the cloud that are long-lasting, agile, and maintainable. You’ll also gain practical knowledge of container-based and serverless application development. Furthermore, you’ll discover how to leverage AWS CDK to build cloud solutions using code instead of configuration files. Finally, you’ll explore current community best practices for solving production issues when dealing with CDK applications. By the end of this book, you’ll have practical knowledge of CDK, and you’ll be able to leverage the power of AWS with code that is simple to write and maintain using AWS CDK.

Troubleshooting common problems with CDK

As you embark on your journey of coding CDK applications, you may encounter certain challenges that are common among CDK beginners. In this section, we will address some of these challenges and provide effective remedies to overcome them.


A common issue when using CDK is deploying to a new environment, which may result in an error stating that the environment has not been bootstrapped. Bootstrapping refers to deploying a pre-created AWS stack to a specific Region. This is necessary to set up the required resources for deploying any stack, S3 buckets, ECR repositories, and so on. As you may recall, we had to deal with this at the beginning of this book.

To resolve this issue, you can use the following command:

$ cdk bootstrap

You will have to do this everytime to you deploy a CDK project in new AWS accounts.
