Add Docker support with SQLite for containerized deployment

[Copilot]

Adds production-ready Docker configuration to deploy Splitify with SQLite in a containerized environment.

Changes

Docker Infrastructure

• Dockerfile - PHP 8.4 FPM (Debian) with required extensions (pdo_sqlite, mbstring, exif, pcntl, bcmath, gd, opcache), Node.js for Vite builds, Nginx, and Supervisor
• docker-compose.yml - Single-command deployment with volume persistence, health checks, and environment configuration
• .dockerignore - Optimized build context excluding node_modules, vendor, build artifacts

Runtime Configuration

• docker/nginx.conf - Main Nginx config with gzip, logging, security headers
• docker/default.conf - Laravel site config with PHP-FPM integration and static asset caching
• docker/supervisord.conf - Process manager for PHP-FPM, Nginx, and queue worker
• docker/entrypoint.sh - Initialization script handling .env creation, key generation, database setup, migrations, and config caching

Documentation

• DOCKER.md - Complete usage guide, environment variables, troubleshooting, production deployment
• README.md - Updated with Docker quick start as recommended installation method

Quick Start

docker-compose up -d
# Application available at http://localhost:8000

The entrypoint automatically handles database initialization, migrations, and Laravel optimization on first run. Data persists via volumes for database/database.sqlite and storage/.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• github.com (HTTP Only)
  • Triggering command: /usr/bin/ssh -o SendEnv=GIT_PROTOCOL [email protected] git-upload-pack 'webmozarts/assert.git' (packet block)
  • Triggering command: /usr/bin/ssh -o SendEnv=GIT_PROTOCOL [email protected] git-upload-pack 'doctrine/inflector.git' (packet block)
  • Triggering command: /usr/bin/ssh -o SendEnv=GIT_PROTOCOL [email protected] git-upload-pack 'doctrine/lexer.git' (packet block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Create a Dockerfile for the repository 404Simon/splitify that sets up the application to run with SQLite. The Dockerfile should include all necessary steps to install dependencies, configure the application for SQLite, and ensure the application starts correctly within the container.
