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.

Creating the service mesh

With Istio deployed, we are ready to create the service mesh. We will use the kubernetes/scripts/deploy-dev-env.bash script to set up an environment for development and testing.

The steps required to create the service mesh are basically the same as those we used in Chapter 17, Implementing Kubernetes Features as an Alternative (refer to the Testing with Kubernetes ConfigMaps, secrets, and ingress section). Let's first see what additions have been made to the Kubernetes definition files to set up the service mesh before we run the commands to create the service mesh.

Source code changes

To be able to run the microservices in a service mesh managed by Istio, the following changes have...
