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.

Preface

The Jenkins dashboard


The Jenkins dashboard is a simple and powerful place where we can manage all builds and therefore manage the application delivery pipeline as well. Open http://<localhost or IP address>:8080 from browser. Log in with the user credentials which we created earlier. It will direct us to the dashboard.

Let's understand the dashboard parameters:

  • New Item: It is used to create a new build job, pipeline, or build flow in Jenkins 2:

  • Manage Jenkins: It allows a Jenkins 2 administrator to manage plugins, users, security, nodes, credentials, global tool configuration, and so on:

  • To know about the existing nodes used for build execution, click on Manage Nodes. The master node entry will be available. It is the node where Jenkins is installed. We can add multiple slave nodes to distribute the load, which we will learn later in this chapter:

Now that we have installed Jenkins and become familiar with the Jenkins dashboard, the next step is to configure different tools that...
