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 HTTPS for Spring Boot

If you want to use SSL and serve your RESTful APIs over HTTPS, you will need to generate a certificate. The fastest way to achieve this is through a self-signed certificate, which is enough for development mode. JRE provides a simple tool for certificate management—keytool. It is available under your JRE_HOME\bin directory. The command in the following code generates a self-signed certificate and puts it into the PKCS12 KeyStore. Besides KeyStore's type, you will also have to set its validity, alias, and the name of the file. Before starting the generation process, keytool will ask you for your password and some additional information, as follows:

keytool -genkeypair -alias account-key -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore account-key.p12 -validity 3650

Enter keystore password:
