Blue Ocean - Create/Edit a Pipeline

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

We spend time reviewing the key Jenkins features and associated terminology. We then explore 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:

• Creating and configuring pipelines using a Jenkinsfile
• Configuring Jenkins pipelines using the Blue Ocean interface
• Defining build execution environments using docker containers
• Setting up and scaling out Jenkins with multiple build agents and executors using SSH
• Setting up build pipelines for Java-based projects using Gradle

Learning Objectives

What you'll learn:

• How to scale out Jenkins using Master and Build Agent setups using SSH
• The benefits of codifying pipeline build instructions using a Jenkinsfile
• How to leverage Docker containers within a Jenkins pipeline to provide additional build isolation and flexibility
• How to install and use more modern pipeline centric BlueOcean user interface
• 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
