Hands-On Microservices with Spring Boot and Spring Cloud

By: Magnus Larsson

Overview of this book

Microservices architecture allows developers to build and maintain applications with ease, and enterprises are rapidly adopting it to build software using Spring Boot as their default framework. With this book, you’ll learn how to efficiently build and deploy microservices using Spring Boot. This microservices book will take you through tried and tested approaches to building distributed systems and implementing microservices architecture in your organization. Starting with a set of simple cooperating microservices developed using Spring Boot, you’ll learn how you can add functionalities such as persistence, make your microservices reactive, and describe their APIs using Swagger/OpenAPI. As you advance, you’ll understand how to add different services from Spring Cloud to your microservice system. The book also demonstrates how to deploy your microservices using Kubernetes and manage them with Istio for improved security and traffic management. Finally, you’ll explore centralized log management using the EFK stack and monitor microservices using Prometheus and Grafana. By the end of this book, you’ll be able to build microservices that are scalable and robust using Spring Boot and Spring Cloud.

Deploying Our Microservices to Kubernetes

In this chapter, we will deploy the microservices in this book to Kubernetes. We will also learn about some of the core features of Kubernetes, such as using Kustomize to configure deployments for different runtime environments and using Kubernetes deployments object for rolling upgrades. Before we do that, we need to review how we use service discovery. Since Kubernetes comes with built-in support for service discovery, it seems unnecessary to deploy our own since we have been using Netflix Eureka up to this point.

The following topics will be covered in this chapter:

  • Replacing Netflix Eureka with Kubernetes Service objects and kube-proxy for service discovery
  • Using Kustomize to prepare the microservices to be deployed in different environments
  • Testing the deployments with a version of the test script, test-em-all.bash
  • Performing...
