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.

Adding databases to the Docker Compose landscape

Now, we have all of the source code in place. Before we can start up the microservice landscape and try out the new APIs together with the new persistence layer, we must start up some databases.

We will bring MongoDB and MySQL into the system landscape controlled by Docker Compose and add configuration to our microservices so that they can find their databases when running, either with or without running as a Docker container.

The Docker Compose configuration

MongoDB and MySQL are declared as follows in the Docker Compose configuration file, docker-compose.yml:

mongodb:
image: mongo:3.6.9
mem_limit: 350m
ports:
- "27017:27017"
command: mongod --smallfiles

mysql:
