Mastering Spring Cloud

By: Piotr Mińkowski

Overview of this book

Developing, deploying, and operating cloud applications should be as easy as local applications. This should be the governing principle behind any cloud platform, library, or tool. Spring Cloud–an open-source library–makes it easy to develop JVM applications for the cloud. In this book, you will be introduced to Spring Cloud and will master its features from the application developer's point of view. This book begins by introducing you to microservices for Spring and the available feature set in Spring Cloud. You will learn to configure the Spring Cloud server and run the Eureka server to enable service registration and discovery. Then you will learn about techniques related to load balancing and circuit breaking and utilize all features of the Feign client. The book now delves into advanced topics where you will learn to implement distributed tracing solutions for Spring Cloud and build message-driven microservice architectures. Before running an application on Docker container s, you will master testing and securing techniques with Spring Cloud.

Creating a Docker image with microservices

We have already discussed the basic Docker commands that are available for running, creating, and managing containers. It's now time to create and build our first Docker image that starts the sample microservice that we introduced in the previous chapter. For that, we should move back to the repository available at the address and then switch to the branch feign_with_discovery  on There, you will find a Dockerfile for every single microservice, gateway, and discovery. Before discussing these examples however we should refer to the Dockerfile reference to understand the basic commands that we can place there. In fact, Dockerfile is not the only way to build Docker images; we're also going to show you how to create an image with a microservice using the Maven plugin.
