Jenkins 2 Bootcamp: Fully Automate Builds to Deployment 2019

An introduction to the Jenkins build server using continuous integration and deployment techniques -- all step by step.
Instructor:

12,324 students enrolled
English
Install Jenkins CI server on Windows
Install and configure several tools commonly used with Jenkins
Understand the basics of continuous inspection, continuous integration, and continuous deployment
Use Jenkins effectively to build, test, analyze and deploy Java projects
Apply the techniques and experience to implement Jenkins and/or a continuous integration system

This is a comprehensive course designed to show how to setup and run a Jenkins CI server starting with continuous inspection (build, test and analysis) all the way through to continuous deployment. This course provides a strong foundation for implementing continuous inspection, continuous integration, continuous delivery, and even continuous deployment at your company or studio. In order to ikeep the course short and to-the-point, several decisions were made in order to provide a complete path from CI to CD.

The pipeline created in this course consists of the following:

  • Jenkins CI server installed and configured on Windows
  • Git as the source control system
  • Java as the main programming language of build projects
  • Maven as the build tool
  • Findbugs, PMD, and Checkstyle as the static code analysis tools
  • Tomcat as the deployment server

This set of tools provides a comprehensive, end-to-end implementation continuous deployment pipeline. Jenkins can be installed on many operating systems and supports a myriad of tools and technologies — which means, this course provides tremendous value to those comfortable or interested in other operating systems and/or technologies.

Course Outline

Introduction provides an overview for the course, which leas to the Core Concepts for Jenkins. This provides a foundation for the remainder of the course.

Installation provides step-by-step instructions on how to setup Jenkins and all the related tools specifically on Windows. The same principles are applicable to other operating systems as well.

The Basics provides a first look at Jenkins at work with a very simple “freestyle” project. This allows us to learn the Jenkins interface and the key features it provides.

After that, we dive into Maven Projects specifically — since Jenkins natively understand Maven and thus provides special features for Maven projects.

Jenkins can do so much more than simply building. In Test & Quality, we hook up a standard set of unit testing and quality analysis tools for Java projects. Then, we use that information to affect the build status based on established standards.

We also cover how to use Jenkins as an artifact repository which is used to store the build artifacts, like jars and wars, after successful builds. This is particularly useful when integrating Jenkins with other tools in a more comprehensive software delivery strategy.

Then, we bring everything together for Deployment to a running Tomcat server. Don’t worry, I’ll walk you through the complete setup and configuration to work seamlessly with Jenkins!

Finally, no course would be complete without talking about Security. In this final chapter, we setup Jenkins to allow users to login and only see their projects.

Course Features

Presentations provide audio/video training of conceptual ideas in each major area or introduction of new concepts.

Screencasts provide a video of the instructor’s computer system with any actions, commands, or screens displayed and narrated. There are several hours of screencat video content — it makes up the vast majority of the course. Any command line based screencast will include a command listing in the lecture downloads.

Manually Disable Security

Editing the Jenkins configuration file as a last resort if you manage to lock yourself out of your Jenkins installation and just have to get back in.

Enable Security and Login

Enabling security within Jenkins by going to configure global security under our Jenkins management tools. This will also allow us to set up some basic security features, such as restricting non-logged in users from building or editing projects.

4
Adding Users in Matrix-Based Security

Setting up matrix-based security in order to offer finer permissions for each individual logged in user, as well as users who aren't logged in, and a special admin user account. This includes permissions that vary on a project by project basis.
