Hands-On Microservices with Spring Boot and Spring Cloud

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 to Kubernetes for development and test

In this section, we will deploy the microservices in an environment to be used for development and test activities, for example, system integration tests. This type of environment is used primarily for functional tests and is therefore configured to use minimal system resources.

Since the deployment objects in the base folder are configured for a development environment, they don't need any further refinement in the overlay for development. We only have to add deployment and service objects for the three resource managers for RabbitMQ, MySQL, and MongoDB in the same way as when using Docker Compose. We will deploy the resource managers in the same Kubernetes namespace as the microservices. This is illustrated by the following diagram:

The definition files for the resource managers can be found in the kubernetes...
