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.

Running tests with Docker Compose

As mentioned in Chapter 17, Implementing Kubernetes Features as an Alternative (refer to the Verifying that the microservices work without Kubernetes section), it is important to ensure that the source code of the microservices doesn't become dependent on a platform such as Kubernetes or Istio from a functional perspective.

To verify that the microservices work as expected without the presence of Kubernetes and Istio, run the tests as described in Chapter 17, Implementing Kubernetes Features as an Alternative (refer to the Testing with Docker Compose section). Since the default values of the test script, test-em-all.bash, are changed, as described previously in the Running commands to create the service mesh section, the following parameters must be set when using Docker Compose: HOST=localhost PORT=8443 HEALTH_URL=https...
