Mastering AWS CloudFormation - Second Edition

Overview of this book

The advent of DevOps and the cloud revolution has compelled software engineers and operations teams to rethink how to manage complex infrastructures and build resilient solutions. With this AWS book, you’ll find out how you can use Infrastructure as Code (IaC) to simplify infrastructure operations and manage the modern cloud with AWS CloudFormation. This guide covers AWS CloudFormation comprehensively, from template structures to developing complex and reusable infrastructure stacks. It takes you through template validation, stack deployment, and handling deployment failures. It also demonstrates the use of AWS CodeBuild and CodePipeline for automating resource delivery and implementing continuous integration and continuous delivery (CI/CD) practices. As you advance, you’ll learn how to modularize and unify your template on the fly using macros or by fixating the version using modules. You’ll create resources outside of AWS with custom resources and catalog them with the CloudFormation registry. Finally, you’ll improve the way you manage the modern cloud environment on AWS by extending CloudFormation through the AWS serverless application model (SAM) and the AWS cloud development kit (CDK). By the end of this book, you’ll have mastered key AWS CloudFormation concepts and will be able to extend its capabilities for developing and deploying your own infrastructure.

Creating a CI/CD pipeline with CloudFormation and CodePipeline

Before we begin creating the pipeline, let’s revise what a CI/CD pipeline actually is. Any CI/CD pipeline (in terms of software development) consists of stages.

Those stages are usually as follows (we will practice all of these steps later):

  1. Pre-build: Pull the code from source code management and install the dependencies.
  2. Build: Run the build and retrieve the artifacts.
  3. Test: Run a test suite against the build.
  4. Package: Store the build artifacts in the artifact storage.
  5. Deploy: Deploy a new version on the environment.

If any of these steps fail, the build system will trigger an error.

So, how can we apply the same steps on CloudFormation? Usually, it depends on the Continuous Integration (CI) system. In our case, these stages will do the following:

  1. Pre-build: Store the code (for example, the templates) in AWS CodeCommit and use AWS CodeBuild as a build system. We will...
