Updated Project Integration

Repository: Vitual-Browser

Step-by-Step Integration with Vitual-Browser

1. Clone the Repository

Start by cloning the Vitual-Browser repository to your local environment:

git clone https://github.com/jaiswaladi246/Vitual-Browser.git
cd Vitual-Browser
Enter fullscreen mode Exit fullscreen mode

2. Build and Test Locally

2.1 Build the Application

Since Vitual-Browser appears to be a Node.js application, you need to build it. Ensure you have Node.js and npm installed.

# Install dependencies
npm install

# Build the project (if applicable)
npm run build
Enter fullscreen mode Exit fullscreen mode

2.2 Run Tests 

npm test
Enter fullscreen mode Exit fullscreen mode

3. Containerize the Application

3.1 Create a Dockerfile

In the root of your Vitual-Browser project, create a Dockerfile:

# Use official Node.js image as base
FROM node:14

# Create and set working directory
WORKDIR /usr/src/app

# Copy package.json and package-lock.json
COPY package*.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application
COPY . .

# Build the application (if applicable)
RUN npm run build

# Expose port (adjust if necessary)
EXPOSE 3000

# Start the application
CMD ["npm", "start"]
Enter fullscreen mode Exit fullscreen mode

3.2 Build and Push Docker Image 

# Build the Docker image
docker build -t myrepo/vitual-browser:latest .

# Push the Docker image to Docker Hub
docker tag myrepo/vitual-browser:latest myrepo/vitual-browser:v1.0.0
docker push myrepo/vitual-browser:v1.0.0
Enter fullscreen mode Exit fullscreen mode

4. Deploy to Kubernetes (Amazon EKS)

4.1 Create Kubernetes Manifests

Deployment Manifest (deployment.yaml):

apiVersion: apps/v1
kind: Deployment
metadata:
  name: vitual-browser-deployment
spec:
  replicas: 3
  selector:
    matchLabels:
      app: vitual-browser
  template:
    metadata:
      labels:
        app: vitual-browser
    spec:
      containers:
      - name: vitual-browser
        image: myrepo/vitual-browser:v1.0.0
        ports:
        - containerPort: 3000
Enter fullscreen mode Exit fullscreen mode

Service Manifest (service.yaml):

apiVersion: v1
kind: Service
metadata:
  name: vitual-browser-service
spec:
  type: LoadBalancer
  selector:
    app: vitual-browser
  ports:
    - protocol: TCP
      port: 80
      targetPort: 3000
Enter fullscreen mode Exit fullscreen mode

4.2 Apply the Manifests 

kubectl apply -f deployment.yaml
kubectl apply -f service.yaml
Enter fullscreen mode Exit fullscreen mode

5. CI/CD Integration with Jenkins

5.1 Update Jenkinsfile

In your Jenkinsfile, add stages to build, test, and deploy the application:

pipeline {
  agent any
  stages {
    stage('Checkout') {
      steps {
        git 'https://github.com/jaiswaladi246/Vitual-Browser.git'
      }
    }
    stage('Build') {
      steps {
        sh 'npm install'
        sh 'npm run build'
      }
    }
    stage('Test') {
      steps {
        sh 'npm test'
      }
    }
    stage('Docker Build and Push') {
      steps {
        sh 'docker build -t myrepo/vitual-browser:latest .'
        sh 'docker push myrepo/vitual-browser:latest'
      }
    }
    stage('Deploy') {
      steps {
        sh 'kubectl apply -f deployment.yaml'
        sh 'kubectl apply -f service.yaml'
      }
    }
  }
}
Enter fullscreen mode Exit fullscreen mode

6. Monitoring and Security

  • Prometheus and Grafana: Ensure Prometheus is configured to scrape metrics from the Vitual-Browser application if it exposes any.
  • Trivy and SonarQube: Integrate Trivy in the Jenkins pipeline for scanning Docker images and SonarQube for code quality.

Conclusion

This integration ensures a smooth CI/CD pipeline for the Vitual-Browser application. By following these steps, you’ll have a robust, automated setup for building, testing, deploying, and monitoring your application.

Hi. Thanks for the article. I had four questions:

  1. From start to end is it completely free?
  2. It seems this was done in Linux. But I am a Windows User. Any help?
  3. I didn't quite get your featured comment Updated Project Integration. Like, is it a particular application of a general procedure you delineated in the article, applying the process to deploy a nodejs application? Also, in case there is a django application to deploy, how to do it?
  4. Finally, how would the pushed website be accessible? Like, what would be the URL?
