Docker Setup for Mainty

Quick Start

Build and Run

# Build the Docker image
docker-compose build

# Start the container
docker-compose up -d

# View logs
docker-compose logs -f

The application will be available at: http://localhost:8080

Stop the Application

docker-compose down

What's Included

• PHP 8.4 with Apache
• SQLite with PDO extension
• mod_rewrite enabled for pretty URLs
• Persistent data volume for the database

Configuration

Change Port

Edit docker-compose.yml and modify the ports section:

ports:
  - "3000:80"  # Access on port 3000 instead

Development Mode

To sync code changes without rebuilding, uncomment this line in docker-compose.yml:

volumes:
  - ./data:/var/www/html/data
  - .:/var/www/html  # Uncomment this line

Then restart:

docker-compose restart

Data Persistence

The SQLite database is stored in the ./data directory on your host machine, which is mounted to the container. This means:

• ✅ Your data persists even if you stop/remove the container
• ✅ You can backup by copying the data folder
• ✅ Database survives container rebuilds

Useful Commands

# Rebuild after code changes
docker-compose up -d --build

# View container logs
docker-compose logs -f mainty

# Access container shell
docker-compose exec mainty bash

# Stop and remove everything
docker-compose down -v

# Check container status
docker-compose ps

Troubleshooting

Permission Issues

If you get permission errors with the database:

chmod -R 755 data

Port Already in Use

If port 8080 is already in use, change it in docker-compose.yml:

ports:
  - "8081:80"  # Use a different port

Reset Everything

To start fresh:

docker-compose down -v
rm -rf data/mainty.db
docker-compose up -d

Then access http://localhost:8080 to run setup again.

Production Deployment

For production:

1. Set DEBUG to false in config.php
2. Use environment variables for sensitive data
3. Consider using a reverse proxy (nginx) in front
4. Enable HTTPS

Example production docker-compose.yml:

version: '3.8'

services:
  mainty:
    build: .
    container_name: mainty-app
    ports:
      - "8080:80"
    volumes:
      - ./data:/var/www/html/data
    environment:
      - APACHE_DOCUMENT_ROOT=/var/www/html
    restart: always
    logging:
      driver: "json-file"
      options:
        max-size: "10m"
        max-file: "3"
