Building and Delivering Microservices on AWS

Overview of this book

Reliable automation is crucial for any code change going into production. A release pipeline enables you to deliver features for your users efficiently and promptly. AWS CodePipeline, with its powerful integration and automation capabilities of building, testing, and deployment, offers a unique solution to common software delivery issues such as outages during deployment, a lack of standard delivery mechanisms, and challenges faced in creating sustainable pipelines. You’ll begin by developing a Java microservice and using AWS services such as CodeCommit, CodeArtifact, and CodeGuru to manage and review the source code. You’ll then learn to use the AWS CodeBuild service to build code and deploy it to AWS infrastructure and container services using the CodeDeploy service. As you advance, you’ll find out how to provision cloud infrastructure using CloudFormation templates and Terraform. The concluding chapters will show you how to combine all these AWS services to create a reliable and automated CodePipeline for delivering microservices from source code check-in to deployment without any downtime. Finally, you’ll discover how to integrate AWS CodePipeline with third-party services such as Bitbucket, Blazemeter, Snyk, and Jenkins. By the end of this microservices book, you’ll have gained the hands-on skills to build release pipelines for your applications.

Deploying application on EKS cluster

We will deploy the aws-code-pipeline application that we created in previous chapters. This time, we will deploy it to the EKS Kubernetes cluster using CodePipeline. The following diagram shows the overall deployment structure; we will use the CodeBuild service to create artifacts and Docker images and push that container image to the ECR repository:

This container image is referenced by the deployment.yaml file and deployed to the Kubernetes cluster. The CodeBuild service needs appropriate access to connect with ECR and the Kubernetes cluster to deploy the code. Once the application is deployed, it passes the control to another chap-13-test-application CodeBuild project, which is responsible for connecting to the application using a load balancer to test the success of the deployment. Let’s go through this journey step by step in the following sections...
