Overview of this book

The DevOps culture is growing at a massive rate, as many organizations are adopting it. However, implementing it for web applications is one of the biggest challenges experienced by many developers and admins, which this book will help you overcome using various tools, such as Chef, Docker, and Jenkins. On the basis of the functionality of these tools, the book is divided into three parts. The first part shows you how to use Jenkins 2.0 for Continuous Integration of a sample JEE application. The second part explains the Chef configuration management tool, and provides an overview of Docker containers, resource provisioning in cloud environments using Chef, and Configuration Management in a cloud environment. The third part explores Continuous Delivery and Continuous Deployment in AWS, Microsoft Azure, and Docker, all using Jenkins 2.0. This book combines the skills of both web application deployment and system configuration as each chapter contains one or more practical hands-on projects. You will be exposed to real-world project scenarios that are progressively presented from easy to complex solutions. We will teach you concepts such as hosting web applications, configuring a runtime environment, monitoring and hosting on various cloud platforms, and managing them. This book will show you how to essentially host and manage web applications along with Continuous Integration, Cloud Computing, Configuration Management, Continuous Monitoring, Continuous Delivery, and Deployment.

Understanding the client-server architecture of Docker

Let's recollect our main objective: we want to deploy a sample Spring application named Pet-clinic on our Tomcat server. How it is different when we install tomcat in the virtual machine and use containers? In Container environment, host OS is installed and then it is used to host container layer. Container layer is used for provisioning container instances. Container instances are extremely lightweight and efficient as extra libraries or resources are needed for the operating system that is needed in the virtual machine while not in case of containers.

For that, in the rest of the section, we will try to use the existing Tomcat image and also create a sample image with a Tomcat installation:

  1. Navigate to , and after you login, search for tomcat in the search section. Click on tomcat, and you will be presented with something like this:

  2. Verify the images with docker images, and then try to run the Tomcat image. It...
