NetflixOps: Building a Robust CI/CD Pipeline for Netflix Clone

Overview

In this blog post, we'll dive deep into creating a comprehensive CI/CD pipeline for a Netflix clone application. We'll explore how to set up a robust development environment using various DevOps tools and best practices. Let's get started!

Tools & Plugins Used

• Jenkins
• Prometheus
• Grafana
• Docker
• SonarQube
• OWASP
• Trivy Scan

Detailed Steps

1. Infrastructure Setup

To begin, we'll need to set up our infrastructure:

• Create 3 EC2 instances:
  1. Application server (t2.large)
  2. Monitoring server (t2.micro)
  3. Pipeline server (t2.large)

2. Application Overview

We'll be using a Netflix clone built with React and TypeScript. You can find the repository here: Netflix Clone

3. Docker Compose Setup

Run the following command to start our Docker containers:

docker-compose up

This will spin up 5 containers:

• Node Exporter
• LocalStack
• Grafana
• Jenkins
• Trivy

4. Prometheus Configuration

Configure the prometheus.yml file to set up monitoring for all our services and dependencies.

5. Jenkins Configuration

1. Access Jenkins at https://localhost:8080/
2. Retrieve the initial admin password:

   sudo docker exec ${CONTAINER_ID or CONTAINER_NAME} cat /var/jenkins_home/secrets/initialAdminPassword

3. Install the Email Extension plugin

6. Essential Jenkins Plugins

Install the following plugins:

• Eclipse Temurin Installer
• SonarQube Scanner
• NodeJS Plugin
• Docker-related plugins (Docker, Docker API, Docker Commons, Docker Pipelines, docker-build-step)
• OWASP Dependency Check Plugin

7. Tool Configuration

Configure the following tools in Jenkins:

• Java
• NodeJS
• OWASP
• Email
• SonarQube

8. Global Credentials

Add global credentials for:

• Docker Hub
• Email service

9. Jenkins Job Creation

1. Create a new pipeline job named "Netflix"
2. Add the Jenkins pipeline script from Jenkins/jenkinsfile
3. Review and modify the script as needed

10. Pipeline Execution

Run the pipeline and watch as it:

• Checks out the code
• Builds the application
• Runs tests
• Performs security scans
• Creates a Docker image
• Pushes the image to Docker Hub

11. Verification

Once the pipeline completes successfully, pull and run the Docker image to verify the application.

Conclusion

Congratulations! You've successfully set up a comprehensive CI/CD pipeline for a Netflix clone application. This setup incorporates best practices in continuous integration, security scanning, and monitoring, ensuring a robust and reliable deployment process.

By leveraging tools like Jenkins, Docker, SonarQube, and Prometheus, you've created a scalable and maintainable DevOps workflow that can be adapted for various applications.

Remember to regularly update your tools and security scans to keep your pipeline in top shape. Happy coding!
