Spring 5.0 Microservices - Second Edition

By: Rajesh R V

Overview of this book

The Spring Framework is an application framework and inversion of the control container for the Java platform. The framework’s core features can be used by any Java application, but there are extensions to build web applications on top of the Java EE platform. This book will help you implement the microservice architecture in Spring Framework, Spring Boot, and Spring Cloud. Written to the latest specifications of Spring that focuses on Reactive Programming, you’ll be able to build modern, internet-scale Java applications in no time. The book starts off with guidelines to implement responsive microservices at scale. Next, you will understand how Spring Boot is used to deploy serverless autonomous services by removing the need to have a heavyweight application server. Later, you’ll learn how to go further by deploying your microservices to Docker and managing them with Mesos. By the end of the book, you will have gained more clarity on the implementation of microservices using Spring Framework and will be able to use them in internet-scale deployments through real-world examples.

Running BrownField services on EC2


In this section, we will set up BrownField microservices on the EC2 instances created. In this case, the build is set up in the local desktop machine and the binaries will be deployed into AWS. Follow these steps to set up services on the EC2 instance:

  1. Change all IP addresses in *.properties to reflect the IP address of the EC2 instance.
  2. Change the Java files mentioned earlier under chapter9.book and chapter9.website to reflect the IP addresses.
  1. On the local machine, recompile all projects and create Docker images for all microservices. Push all of them to the Docker Hub registry.
  2. Set up Java 8 on the EC2 instance.
  3. Execute the following commands in sequence:
sudo docker run --net=host rabbitmq:3
      sudo docker run -p 8090:8090 rajeshrv/search:1.0
      sudo docker run -p 8001:8001 rajeshrv/website:1.0
  1. Validate whether all services are working by opening the URL of the website and execute search. Note that we will be using the public IP of the EC2 instance in...
