CI CD Pipeline Using Jenkins

Introduction

• Topic: CI CD pipeline using Jenkins.
• Agenda:
  1. Introduction to DevOps.
  2. Importance of CI CD pipeline.
  3. Building a sample pipeline using Jenkins.
  4. Demo of setup and pipeline processing.

What is DevOps?

• Definition: Combination of development and operations.
• Roles:
  • Development: Prepare source code, use various coding tools, interact with testing, ensure product performance.
  • Operations: Deploy source code, manage VMs, perform patching, maintain production environments.
• Benefits:
  • Frequent releases
  • Improved team collaboration
  • Better and efficient management
  • Reduced bugs in production
  • Faster issue resolution

Importance of CI CD Pipeline

• Definition: Continuous Integration (CI) and Continuous Delivery (CD) are the backbones of DevOps.
• Functions:
  • Build and compile source code
  • Run test cases
  • Deploy to specific environments
• Benefits:
  • Automated sequence of tasks
  • Reduces human error
  • Boosts team productivity and confidence

Continuous Integration (CI)

• Definition: Practice of integrating code into a shared repository, automating build verification and test case execution.
• Benefits:
  • Easier and faster bug detection
  • Automates processes like build and test
  • Enhances collaboration between teams

Continuous Delivery (CD)

• Definition: Phase where changes are made and validated before deployment.
• Goal: Efficient and swift deployments.
• Benefits:
  • Quicker deployment cycles
  • Reduces manual processes
  • Ensures higher quality releases

Jenkins Overview

• Tool: Open-source orchestration and automated tool for CI/CD.
• Advantages:
  • Open-source with extensive plugin support (e.g., Kubernetes, Docker, etc.)
  • Easy integration for developers
  • Wide support for programming languages (Java, .NET, Node.js, etc.)

Building a CI CD Pipeline with Jenkins

• Requirements:
  • Java JDK (for compilation)
  • Linux commands knowledge
• Steps:
  1. Download JDK and Jenkins from jenkins.io/download.
  2. Execute java –jar jenkins.war to run Jenkins.
  3. Access Jenkins via web browser (localhost:8080).
  4. Create a new job in Jenkins.
  5. Choose pipeline job type.
  6. Configure job: add pipeline script or source from a repository.
  7. Execute build and monitor through console output and logs.

Demo Review

• Process:
  1. Download Jenkins setup.
  2. Run Jenkins and configure job.
  3. Use pipeline script directly or source from SCM (e.g., GitHub).
  4. Execute the build.
  5. Monitor logs and stages in Jenkins dashboard.
  6. Validate the output and pipeline success.

Conclusion

• Summary: Implementing CI CD pipelines with Jenkins streamlines development and operations, ensuring efficient deployments with minimal manual intervention and higher reliability.
