Docker CI/CD Pipeline

An end-to-end CI/CD pipeline with automated testing, security scanning, and deployment to multiple environments using Docker containers.

Features

• Automated build and test pipeline
• Multi-environment deployment
• Security scanning with SonarQube
• Docker image optimization
• Automated testing
• Environment-specific configurations
• Deployment rollback capability

Pipeline Stages

1. Build

   • Code checkout
   • Dependency installation
   • Docker image building
   • Multi-stage builds for optimization

2. Test

   • Unit testing
   • Integration testing
   • Code coverage analysis
   • SonarQube analysis

3. Security Scan

   • SonarQube security rules
   • Docker image scanning
   • Dependency vulnerability check
   • OWASP security scanning

4. Deploy

   • Environment validation
   • Configuration injection
   • Rolling updates
   • Health checks

Prerequisites

• Jenkins server
• Docker
• GitLab/GitHub account
• SonarQube server
• Docker registry access

Quick Start

For detailed setup instructions, please refer to our Setup Guide.

1. Clone the repository:

git clone https://github.com/nived2/docker-cicd.git
cd docker-cicd

2. Configure Jenkins:

   • Install required plugins
   • Configure Docker credentials
   • Set up SonarQube connection
   • Configure environment variables

3. Set up pipeline:

# Create Jenkins pipeline using Jenkinsfile
# Configure webhook in GitLab/GitHub

Jenkins Pipeline Configuration

pipeline {
    agent any
    
    stages {
        stage('Build') {
            steps {
                sh 'docker build -t myapp .'
            }
        }
        
        stage('Test') {
            steps {
                sh 'docker run myapp npm test'
            }
        }
        
        stage('Security Scan') {
            steps {
                sh 'sonar-scanner'
            }
        }
        
        stage('Deploy') {
            steps {
                sh './scripts/deploy.sh'
            }
        }
    }
}
