Jenkins: Practical Implementation

Enough theory—let’s get our hands dirty. This section is all about putting Jenkins to work in real-world CI/CD projects. From setting up automated pipelines to securing and scaling Jenkins, these hands-on projects will solidify your knowledge and prepare you for production-grade implementations.

Projects Covered#

Setting Up Jenkins for Continuous Integration#

• Installing and configuring Jenkins.
• Creating and managing Jenkins jobs.
• Setting up SCM integration (Git, GitHub, GitLab, Bitbucket).
• Automating builds and test executions.

Creating Automated CI/CD Pipelines for Kubernetes Deployment#

• Writing and managing Jenkins Pipelines with Jenkinsfile.
• Integrating Docker with Jenkins for containerized builds.
• Deploying applications to Kubernetes clusters using Jenkins.
• Automating versioning and rollbacks in Kubernetes deployments.

Implementing Security and Best Practices in Jenkins#

• Configuring user authentication and role-based access control (RBAC).
• Securing credentials using Jenkins secrets management.
• Implementing audit logging and monitoring.
• Enforcing pipeline security policies.

Scaling Jenkins Agents Dynamically with Kubernetes#

• Setting up Kubernetes-based Jenkins agent autoscaling.
• Using Kubernetes plugin for Jenkins agent provisioning.
• Managing resource allocation and cost optimization.
• Monitoring and troubleshooting Jenkins agent performance.

Hands-on Activities#

• Deploy a sample Java/Python application with CI/CD using Jenkins.
• Implement automated Docker image builds and push to a container registry.
• Secure Jenkins configurations and enforce best security practices.
• Configure and optimize Kubernetes-based Jenkins agent autoscaling.
