Course Introduction

Welcome to the Jenkins Project Course at KodeKloud! In this project-based course, you'll gain real-world experience with Jenkins and other key DevOps tools through hands-on labs in a browser-based environment. This setup enables you to transition quickly from theory to practice without the hassle of setting up local infrastructure.

What You'll Learn

We begin by demystifying the core concepts of Jenkins. Understand what Jenkins is, why it's indispensable in modern development, and how to create and configure Jenkins jobs. Your journey starts with a simple "Hello World" pipeline that lays the foundation for more complex workflows.

Next, you'll integrate Jenkins with Git to manage your source code repository effectively. The course also covers incorporating unit testing using the Pytest framework to ensure code quality. Learn about various build triggers that automate workflows based on code changes or scheduled times. We demonstrate how to make your Jenkins jobs dynamic by leveraging environment variables through practical demonstrations.

pipeline {
    agent any

    environment {
        DB_HOST = '192.168.12.1'
        USERNAME = 'user1'
        PASSWORD = 'password123'
    }

    stages {
        stage('Setup') {
            steps {
                sh 'pip install -r requirements.txt'
            }
        }
        stage('Test') {
            steps {
                sh 'pytest'
            }
        }
    }
}

You will also become proficient in advanced features like nested and parallel stages, which help design complex and efficient pipelines. Learn to enhance your jobs with options, parameters, and user inputs, making your workflows interactive and adaptable. Our step-by-step guidance in job configuration and pipeline execution also includes effective Jenkins plugin management.

Deployment and Advanced Integrations

Single Server Deployment

Learn how to deploy your application on a single server using Jenkins pipelines. Start with basic commands and progress through a hands-on demo that teaches efficient application configuration and deployment.

Below is an example of commands executed on a single server:

ssh -i main.pem [email protected]
mkdir app
cd app
pwd
# /home/ec2-user/app
ls
python3 --version
# Python 3.9.16

Serverless Architecture with AWS Lambda

Explore AWS Lambda in a dedicated section focused on serverless architecture. Learn to deploy Lambda functions using the Serverless Application Model and configure Jenkins pipelines for efficient Lambda deployments. Hands-on demos make serverless application deployment accessible and easy to understand.

Containerization with Docker

Delve into the world of Docker and discover how to build custom Docker images, integrate Jenkins with Docker, and write Dockerfiles for containerization. Additionally, you'll learn to manage Docker Hub credentials securely within Jenkins for robust container deployments.

Orchestration with Kubernetes and AWS EKS

Get acquainted with Kubernetes and AWS EKS to master scalable and reliable container orchestration. This course guides you through working with Kubernetes Pods, replicas, and deployments. You will learn how to set up an EKS cluster and deploy your application using a Jenkins pipeline through practical demos.

Course Outcomes

By the end of this course, you will have a thorough understanding of how to leverage Jenkins, Docker, Kubernetes, and AWS EKS to create robust, scalable, and automated CI/CD pipelines for your applications.
