Rating: 4.4/5

This lesson introduces you to Jenkins, a popular open-source tool used to perform Continuous Integration and Continuous Delivery.

We review the key Jenkins features and associated terminology. We then take you through a deep dive in configuring Jenkins to perform automated builds using the Jenkins web administration console in hands-on demonstrations, familiarising you with Jenkins and how to administer it. We’ll demonstrate features such as:

  • Installing and setting up Jenkins
  • Creating and configuring pipelines manually
  • Creating and configuring pipelines using a Jenkinsfile
  • Triggering build pipelines, manually and automatically
  • Navigating downstream and upstream build projects
  • Connecting to version control repositories such as GitHub
  • Setting up build pipelines for Java-based projects using Gradle
  • Recording artifacts and test results

Learning Objectives

What you'll learn:

  • The basic principles of build automation as implemented within Jenkins and how they should be applied to manage and maintain building, testing, and deploying your own enterprise software projects
  • How to install, set up, and configure Jenkins pipelines
  • The key differences between Jenkins declarative and scripted pipelines
  • How to manage build artifacts and test results
  • How to integrate and leverage third-party build tools like Gradle, Maven, Yarn, Webpack, and many more within a Jenkins pipeline

Demonstration

This training lesson provides many hands-on demonstrations where you will observe first hand how to use Jenkins to build and release different types of software projects, for example:

  • Building a front-end application which has been developed using the React Javascript framework, using technologies such as Webpack and Yarn
  • Building a back-end application developed using Java, Gradle, and Docker, requiring Jenkins to compile the source code, packaging it into a WebArchive file, and then finally releasing it into a Tomcat-based Docker image complete with Splunk-based instrumentation for logging and monitoring

Prerequisites

  • A basic understanding of CICD, or Continuous Integration and Continuous Delivery
  • A basic understanding of software development and the software development life cycle
  • A basic understanding of version control and associated workflows

Intended Audience

  • Software Build and Release Engineers
  • Software Developers
  • DevOps Practitioners
