+# CodeIgniter Chat - Container Orchestration
+
+This document provides comprehensive guidance for deploying the CodeIgniter Chat application using Docker containers and Kubernetes orchestration.
+
+## 🐳 Docker Container Architecture
+
+The application is containerized into multiple components:
+
+### Core Services
+- **Web Application** (`Dockerfile`): PHP 8.4 with Apache, serving the main application
+- **WebSocket Server** (`Dockerfile.websocket`): PHP CLI running the real-time chat server
+- **MySQL Database**: Persistent data storage for messages and sessions
+- **Redis**: Session storage and caching layer
+- **Nginx**: Load balancer and reverse proxy
+
+### Support Services
+- **Frontend Assets** (`Dockerfile.frontend`): Node.js build system for static assets
+- **phpMyAdmin**: Database management (development only)
+- **Redis Commander**: Redis management (development only)
+
+## 🚀 Quick Start
+
+### Prerequisites
+- Docker and Docker Compose installed
+- At least 4GB RAM available
+- Ports 80, 8000, 8080, 8081 available
+
+### Development Deployment
+```bash
+# Make deployment script executable
+chmod +x scripts/deploy.sh
+
+# Deploy in development mode
+./scripts/deploy.sh development
+```
+
+### Production Deployment
+```bash
+# Deploy in production mode
+./scripts/deploy.sh production
+```
+
+## 📋 Container Details
+
+### Web Application Container
+- **Base Image**: php:8.4-apache
+- **Port**: 80
+- **Features**:
+  - PHP extensions: intl, mbstring, json, pdo_mysql, mysqli, zip
+  - Apache with mod_rewrite enabled
+  - Composer for dependency management
+  - Security headers configured
+  - Health checks implemented
+
+### WebSocket Server Container
+- **Base Image**: php:8.4-cli
+- **Port**: 8080
+- **Features**:
+  - Ratchet WebSocket server
+  - Socket extension enabled
+  - Real-time message broadcasting
+  - Connection management
+
+### Database Container
+- **Base Image**: mysql:8.0
+- **Port**: 3306 (internal only in production)
+- **Features**:
+  - Persistent volume for data
+  - Automatic schema initialization
+  - Health checks with mysqladmin
+  - Optimized configuration
+
+### Redis Container
+- **Base Image**: redis:7-alpine
+- **Port**: 6379 (internal only in production)
+- **Features**:
+  - Persistent volume for data
+  - Password protection in production
+  - AOF persistence enabled
+
+## 🔧 Configuration
+
+### Environment Variables
+Set these in your `.env` file or docker-compose environment:
+
+```bash
+# Database
+MYSQL_ROOT_PASSWORD=your_secure_root_password
+MYSQL_DATABASE=ci4_chat
+MYSQL_USER=ci4user
+MYSQL_PASSWORD=your_secure_password
+
+# Redis
+REDIS_PASSWORD=your_redis_password
+
+# Application
+ENCRYPTION_KEY=your_32_character_encryption_key
+CI_ENVIRONMENT=production
+```
+
+### Volume Mounts
+- `mysql_data`: Database persistence
+- `redis_data`: Cache persistence
+- `web_logs`: Apache logs
+- `nginx_logs`: Nginx logs
+- `./writable`: Application writable directory
+
+## 🌐 Service Endpoints
+
+### Development Mode
+- **Main Application**: http://localhost
+- **Nginx Proxy**: http://localhost:8000
+- **Frontend Dev Server**: http://localhost:5173
+- **phpMyAdmin**: http://localhost:8080
+- **Redis Commander**: http://localhost:8081
+- **WebSocket**: ws://localhost:8080
+
+### Production Mode
+- **Application**: http://localhost (via Nginx)
+- **WebSocket**: ws://localhost/websocket (via Nginx proxy)
+
+## 🔍 Monitoring and Health Checks
+
+### Health Check Endpoints
+- **Web**: `GET /` - Returns 200 if application is running
+- **Nginx**: `GET /health` - Returns "healthy" status
+- **MySQL**: `mysqladmin ping` - Database connectivity
+- **Redis**: `redis-cli ping` - Cache connectivity
+
+### Logging
+All services log to dedicated volumes:
+- Web logs: `/var/log/apache2/`
+- Nginx logs: `/var/log/nginx/`
+- Application logs: `./writable/logs/`
+
+### Viewing Logs
+```bash
+# View all service logs
+docker compose logs -f
+
+# View specific service logs
+docker compose logs -f web
+docker compose logs -f websocket
+docker compose logs -f mysql
+```
+
+## 📊 Scaling and Performance
+
+### Horizontal Scaling
+```bash
+# Scale web application
+docker compose up -d --scale web=3
+
+# Scale WebSocket servers
+docker compose up -d --scale websocket=2
+```
+
+### Resource Limits
+Production containers have resource limits:
+- **Web**: 1 CPU, 512MB RAM
+- **WebSocket**: 0.5 CPU, 256MB RAM
+- **Nginx**: 0.5 CPU, 256MB RAM
+
+## 🛡️ Security Features
+
+### Network Security
+- Isolated Docker network
+- Internal service communication
+- External ports only on load balancer
+
+### Application Security
+- Security headers (X-Frame-Options, CSP, etc.)
+- Rate limiting on API endpoints
+- Input validation and sanitization
+- Secure session management with Redis
+
+### Container Security
+- Non-root user execution where possible
+- Read-only root filesystem for stateless services
+- Minimal base images (Alpine Linux)
+- Regular security updates
+
+## 🚨 Troubleshooting
+
+### Common Issues
+
+#### Database Connection Errors
+```bash
+# Check MySQL container
+docker compose logs mysql
+
+# Verify database is accessible
+docker compose exec web php spark migrate:status
+```
+
+#### WebSocket Connection Issues
+```bash
+# Check WebSocket server logs
+docker compose logs websocket
+
+# Test WebSocket connectivity
+docker compose exec web php spark chat:websocket --port=8080
+```
+
+#### Permission Issues
+```bash
+# Fix writable directory permissions
+docker compose exec web chown -R www-data:www-data /var/www/html/writable
+docker compose exec web chmod -R 777 /var/www/html/writable
+```
+
+### Performance Issues
+```bash
+# Monitor resource usage
+docker stats
+
+# Check container health
+docker compose ps
+```
+
+## 🔄 Updates and Maintenance
+
+### Updating Application
+```bash
+# Pull latest code
+git pull origin main
+
+# Rebuild containers
+docker compose build --no-cache
+
+# Deploy with zero downtime
+docker compose up -d --force-recreate
+```
+
+### Database Maintenance
+```bash
+# Backup database
+docker compose exec mysql mysqldump -u root -p ci4_chat > backup.sql
+
+# Restore database
+docker compose exec -i mysql mysql -u root -p ci4_chat < backup.sql
+```
+
+### Container Cleanup
+```bash
+# Remove unused containers and images
+docker system prune -a
+
+# Remove application volumes (⚠️ DATA LOSS)
+docker compose down -v
+```
+
+## 📈 Production Considerations
+
+### Load Balancing
+- Nginx configured for round-robin load balancing
+- WebSocket sticky sessions handled
+- Health checks ensure traffic to healthy containers
+
+### Backup Strategy
+- Database: Automated daily backups
+- Redis: AOF persistence enabled
+- Application: Git-based deployments
+
+### Monitoring Integration
+- ELK stack for log aggregation
+- Prometheus for metrics collection
+- Grafana for visualization
+- Health check endpoints for uptime monitoring
+
+## 🎯 Next Steps
+
+1. **Kubernetes Deployment**: See `README-KUBERNETES.md` for advanced orchestration
+2. **CI/CD Integration**: Set up automated deployments with GitHub Actions
+3. **SSL/TLS**: Configure HTTPS with Let's Encrypt certificates
+4. **Monitoring**: Implement comprehensive monitoring with Prometheus/Grafana
+5. **Backup Automation**: Set up automated backup and disaster recovery procedures

+# Docker Engine for Linux installation script.
+#
+# This script is intended as a convenient way to configure docker's package
+# repositories and to install Docker Engine, This script is not recommended
+# for production environments. Before running this script, make yourself familiar
+# with potential risks and limitations, and refer to the installation manual
+# at https://docs.docker.com/engine/install/ for alternative installation methods.
+#
+# The script:
+#
+# - Requires `root` or `sudo` privileges to run.
+# - Attempts to detect your Linux distribution and version and configure your
+#   package management system for you.
+# - Doesn't allow you to customize most installation parameters.
+# - Installs dependencies and recommendations without asking for confirmation.
+# - Installs the latest stable release (by default) of Docker CLI, Docker Engine,
+#   Docker Buildx, Docker Compose, containerd, and runc. When using this script
+#   to provision a machine, this may result in unexpected major version upgrades
+#   of these packages. Always test upgrades in a test environment before
+#   deploying to your production systems.
+# - Isn't designed to upgrade an existing Docker installation. When using the
+#   script to update an existing installation, dependencies may not be updated
+#   to the expected version, resulting in outdated versions.
+#
+# Source code is available at https://github.com/docker/docker-install/
+#
+# Usage
+# ==============================================================================
+#
+# To install the latest stable versions of Docker CLI, Docker Engine, and their
+# dependencies:
+#
+# 1. download the script
+#
+#   $ curl -fsSL https://get.docker.com -o install-docker.sh
+#
+# 2. verify the script's content
+#
+#   $ cat install-docker.sh
+#
+# 3. run the script with --dry-run to verify the steps it executes
+#
+#   $ sh install-docker.sh --dry-run
+#
+# 4. run the script either as root, or using sudo to perform the installation.
+#
+#   $ sudo sh install-docker.sh
+#
+# Command-line options
+# ==============================================================================
+#
+# --version <VERSION>
+# Use the --version option to install a specific version, for example:
+#
+#   $ sudo sh install-docker.sh --version 23.0
+#
+# --channel <stable|test>
+#
+# Use the --channel option to install from an alternative installation channel.
+# The following example installs the latest versions from the "test" channel,
+# which includes pre-releases (alpha, beta, rc):
+#
+#   $ sudo sh install-docker.sh --channel test
+#
+# Alternatively, use the script at https://test.docker.com, which uses the test
+# channel as default.
+#
+# --mirror <Aliyun|AzureChinaCloud>
+#
+# Use the --mirror option to install from a mirror supported by this script.
+# Available mirrors are "Aliyun" (https://mirrors.aliyun.com/docker-ce), and
+# "AzureChinaCloud" (https://mirror.azure.cn/docker-ce), for example:
+#
+#   $ sudo sh install-docker.sh --mirror AzureChinaCloud
