1. Introduction to Jenkins and CI/CD
-
DevOps Fundamentals: Understanding the principles and methodologies of DevOps, including its phases and benefits.
-
Continuous Integration (CI): Defining CI, its importance in modern software development, and the benefits it brings, such as early bug detection and improved code quality.
-
Continuous Delivery (CD) and Continuous Deployment (CD): Understanding the difference between the two and how Jenkins facilitates both practices.
-
What is Jenkins?: Introduction to Jenkins as an open-source automation server, its architecture (Controller/Agent), and its core functionalities.
-
Jenkins Installation and Setup: Installing Jenkins on various operating systems (Windows, Linux, macOS), configuring the initial setup, and managing the Jenkins environment.
-
Jenkins User Interface (UI) and Navigation: Familiarization with the Jenkins dashboard, job views, and other UI elements for managing projects.
2. Managing Jenkins jobs and projects
-
Creating and Configuring Freestyle Projects: Setting up basic Jenkins jobs to build and test applications.
-
Source Code Management (SCM) Integration: Integrating Jenkins with popular version control systems like Git, GitHub, and Bitbucket for triggering builds based on code changes.
-
Build Triggers: Configuring various triggers to initiate builds, including polling SCM, webhooks, and scheduled builds.
-
Build Steps: Defining the commands and scripts to be executed during the build process, including compiling code, running tests, and packaging applications.
-
Post-build Actions: Configuring actions to be performed after the build, such as archiving artifacts, sending notifications, and triggering downstream jobs.
3. Jenkins pipelines
-
Introduction to Jenkins Pipelines: Understanding the concept of pipelines as code, their benefits for defining and automating complex workflows, and the use of Jenkinsfile.
-
Declarative vs. Scripted Pipelines: Exploring the syntax and advantages of both types of pipelines.
-
Pipeline Stages and Steps: Defining stages (e.g., Build, Test, Deploy) and individual steps within each stage to orchestrate the CI/CD workflow.
-
Building Multibranch Pipelines: Setting up pipelines that automatically create and manage separate pipelines for each branch in a Git repository.
-
Pipeline Development Best Practices: Following best practices for writing maintainable, reusable, and secure pipelines.
-
Jenkins Shared Libraries: Creating and using shared libraries to reuse pipeline code across multiple projects.
4. Advanced Jenkins features
-
Distributed Builds: Setting up Jenkins Master-Agent architecture for distributing build workloads across multiple machines.
-
Jenkins Agents: Configuring and managing Jenkins agents (build agents or slaves) for parallel execution and scalability.
-
Jenkins Plugins: Exploring and utilizing the vast ecosystem of Jenkins plugins for extending functionality, integrating with other tools, and enhancing the CI/CD process.
-
Jenkins Security: Implementing security best practices, managing user accounts, roles, and permissions, and securing the Jenkins environment.
-
Monitoring and Reporting: Setting up monitoring tools and generating reports to track build status, test results, and pipeline performance.
-
Troubleshooting Jenkins Builds: Identifying and resolving common issues and failures in Jenkins builds.
5. Integrating Jenkins with other tools
-
Build Tools: Integrating Jenkins with build automation tools like Maven and Gradle for building Java applications.
-
Containerization: Building and deploying Docker images using Jenkins pipelines.
-
Cloud Platforms: Deploying applications to cloud platforms like AWS, GCP, and Azure using Jenkins pipelines.
-
Infrastructure as Code (IaC): Integrating Jenkins with tools like Terraform and Ansible for automating infrastructure provisioning and configuration.
-
Testing Frameworks: Integrating Jenkins with testing frameworks like JUnit for automated testing and reporting results.
-
Code Quality Tools: Integrating with tools like SonarQube for static code analysis and code quality reporting.
6. Real-world projects and case studies
-
Hands-on Projects: Building a complete CI/CD pipeline for a sample application using Git, Maven, Jenkins, Docker, and Ansible.
-
Case Studies: Analyzing real-world scenarios and understanding how organizations leverage Jenkins to streamline their development workflows.
