Curriculum

Course Introduction

This introductory section sets the stage for the course. The "Welcome" lecture orients you to the course content and structure. The "Support" lecture introduces the Discord community for interaction and assistance, and the final lecture provides information on connecting with the instructor and School of DevOps.

Introduction to Jenkins

This module provides a foundational understanding of Jenkins. It covers the principles of CI/CD, introduces Jenkins and its role, and explores the Jenkins ecosystem. You'll learn the differences between Jenkins and JenkinsX, set up a Jenkins build lab, and configure a Jenkins server. Hands-on practice is included to solidify your learning.

Manually Building CI Pipeline

This section focuses on building a CI pipeline manually. You'll explore the Jenkins dashboard, create a build job for a Java application, incorporate unit tests and packaging, and connect jobs using upstreams and downstreams. The section also covers visualizing pipelines with plugins and using SCM polling. Practical exercises reinforce your learning.

Pipeline as a Code

This module dives into Pipeline as Code using Jenkinsfile. You'll learn the Jenkinsfile syntax, write declarative Jenkinsfiles for a Java application, and use the Blue Ocean UI to manage pipelines. The concepts of multi-branch pipelines and editing pipelines through the web UI are explained. Practical exercises and best practices are included for large projects.

Jenkinsfile Deep Dive (Extra Learning)

This extra learning module provides a deeper understanding of Pipeline as Code in Jenkins. It covers the evolution of Jenkins pipeline automation, compares declarative and scripted pipelines, and explains the syntax and structure of declarative pipelines. Best practices for writing efficient and maintainable pipelines are also discussed.

Enforcing Git Based Workflows

This section emphasizes the importance of Git-based workflows. You'll learn about various Git branching models, configuring branch protection rules, and implementing pull requests and code reviews. It emphasizes best practices for efficient team collaboration.

Integrating Jenkins with Container-based Delivery

This module demonstrates integrating Jenkins with Docker. You'll learn the reasons for and methods of this integration, perform a Docker integration smoke test, configure per-stage Docker agents, and write Dockerfiles. The module covers optimizing images using multi-stage builds and automating the Docker image build and publish process from Jenkins, including configuring Docker registry credentials. Hands-on exercises are included.
