Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Using the Docker registry


The Docker Hub provides a central location to store all Docker images. The images can be stored as public as well as private. In many cases, organizations deploy their own private registries on-premise due to security related concerns.

Follow these steps to set up and run a local registry:

  1. The following command will start a registry that will bind the registry on port 5000:
docker run -d -p 5000:5000 --restart=always --name registry
        registry:latest
  1. Tag search:1.0 to the registry:
docker tag search:1.0 localhost:5000/search:1.0
  1. Push the image to the registry:
docker push localhost:5000/search:1.0
  1. Pull the image back from the registry:
docker pull localhost:5000/search:1.0

Setting up the Docker Hub

In the previous chapter, we played with a local Docker registry. This section will show us how to set up and use the Docker Hub to publish the Docker containers. This is a convenient mechanism to globally access the Docker images. Later in this chapter, the Docker images will...
