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.

Enabling secure communication between client and server

Until now, none of the client's connections were being authenticated by the Eureka Server. While in the development mode, security doesn't really matter as much as in the production mode. The lack of it may be a problem. We would like to have, as a bare minimum, the discovery server secured with basic authentication to prevent unauthorized access to any service that knows its network address. Although Spring Cloud reference material claims that HTTP basic authentication will be automatically added to your Eureka Client, I had to include a starter with security to the project dependencies:


Then, we should enable security and set the default credentials by changing the configuration settings in the application.yml file:

   enabled: true
