Overview of this book

AWS CodeDeploy, AWS CodeBuild, and CodePipeline are scalable services offered by AWS that automate an application's build and deployment pipeline. In order to deliver tremendous speed and agility, every organization is moving toward automating their entire application pipeline. This book will cover all the AWS services required to automate your deployment to your instances. You'll begin by setting up and using one of the AWS services for automation –CodeCommit. Next, you'll learn how to build a sample Maven and NodeJS application using CodeBuild. After you've built the application, you'll see how to use CodeDeploy to deploy the application in EC2/Auto Scaling. You'll also build a highly scalable and fault tolerant Continuous Integration (CI)/Continuous Deployment (CD) pipeline using some easy-to-follow recipes. Following this, you'll achieve CI/CD for a microservice application and reduce the risk within your software development life cycle globally. You'll also learn to set up an infrastructure using CloudFormation templates and Ansible, and see how to automate AWS resources using AWS Lambda. Finally, you'll learn to automate instances in AWS and automate the deployment lifecycle of applications. By the end of this book, you'll be able to minimize application downtime and implement CI/CD, gaining total control over your software development lifecycle.

Building a sample NodeJS application using AWS CodeBuild via Buildspec.yml

In the previous recipe, we saw how to build the application using AWS CodeBuild. However, in that case, we used the build commands (mvn install) in the console only, as shown in the following image:

When it comes to the complex scenario, it means we need more than one build commands and need to perform some additional operations in the build environment. For this, we use the buildspec.yml file.


A build spec is a collection of build commands and related settings; in the YAML format, AWS CodeBuild is used to run a build. This file needs to be checked in with the root folder of the application code. This file will possess Build steps as...
