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.

Setting up a Netflix Eureka server

In this section, we will learn how to set up a Netflix Eureka server for service discovery. Setting up a Netflix Eureka server using Spring Cloud is really easy—just follow these steps:

  1. Create a Spring Boot project using Spring Initializr, as described in Chapter 3, Creating a Set of Cooperating Microservices, in the Using Spring Initializr to generate skeleton code section.
  2. Add a dependency to spring-cloud-starter-netflix-eureka-server.
  3. Add the @EnableEurekaServer annotation to the application class.
  4. Add a Dockerfile, similar to the Dockerfiles that are used for our microservices, with the exception that we export the Eureka default port, 8761, instead of the default port for our microservices, 8080.
  5.  Add the Eureka server to our three Docker Compose files, that is, docker-compose.yml, docker-compose...
