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.

Deploying microservices applications in Kubernetes using Jenkinsfile

This is one of the most important section of the chapter. In this section, we will see how to update the deployment of microservice application in Kubernetes cluster. We will be using the resources that has been created in the recipe Kubernetes on AWS using AWS resources, meaning the ECR repository, EBS volume, deployment of application, and load balancer are already in place.

Scenario: Whenever there is change in the code, a new image should get created. The new image should also get updated in the Kubernetes cluster so that Kubernetes should serve the latest application.

To automate the preceding scenario, we will be using Jenkins, and all the steps and configuration will be written in Jenkinsfile.
