Streamlining Node.js: A Simple CI/CD Journey with Jenkins and Docker 🚀 Day -24

Hello, fellow tech enthusiasts! Today, we're embarking on a straightforward yet impactful journey to set up a CI/CD pipeline for a Node.js application. We'll be using the dynamic duo of Jenkins and Docker, keeping things simple yet effective. By the end of this adventure, you'll not only enhance your CI/CD skills but also have a practical project to showcase on your tech resume. Let's dive in!

## Getting Started: Fork and Connect

**1. Fork the Repository 🍴**

To start, fork the provided repository. This gives you a personalized playground where you can experiment without altering the original source.

**2. Connect Jenkins to GitHub 🎯**

Install essential plugins in Jenkins, create a new Jenkins job for your Node.js application, and connect it to your GitHub repository. This connection allows Jenkins to seamlessly pull your code and trigger builds.

**3. Configure WebHooks 🕸️**

Explore GitHub WebHooks in your repository settings. Set up WebHooks to automate Jenkins builds whenever you push changes. This ensures a smooth integration between GitHub and Jenkins, making your workflow efficient.

## Dockerizing the Application: Keeping It Simple

**1. Create a Docker Compose File 🐳**

Craft a basic `docker-compose.yml` file in your repository. Define services for your Node.js application, including essential environment variables and port configurations. Docker Compose simplifies the deployment process, making it beginner-friendly.

**2. Execute Shell Script in Jenkins 🚀**

In your Jenkins job, add an 'Execute Shell' build step. Write a simple shell script to run your Node.js application using Docker Compose. This script should pull the code, build the Docker image, and deploy the application.

**3. Run the Project and Celebrate 🎉**

Trigger your Jenkins job, either manually or through WebHooks. Watch as Jenkins pulls your code, builds the Docker image, and deploys your Node.js application using the uncomplicated Docker Compose file you created. Celebrate the successful deployment – a small victory is still a victory!

## Conclusion: Your CI/CD Adventure Simplified

Completing this straightforward CI/CD project with Jenkins, GitHub, and Docker is a significant step in your tech journey. By streamlining the process, you not only demonstrate your CI/CD proficiency but also gain a practical understanding of these essential tools. Share your success, update your resume, and continue exploring the vast landscape of CI/CD practices. Happy coding! 🚀
