Add Docker environment via Laravel Sail

[reynaldiarya]

Summary

Add a first-class Docker-based local environment using Laravel Sail. No app logic or database write behavior is changed.

Context / Why

Standardized containers simplify onboarding and ensure environment parity (PHP, DB) without bespoke local setup.

Changes

Dev environment (Laravel Sail)

• Add docker-compose.yml with services:
  • laravel.test (app), mariadb (database)
• Configure port forwards:
  • App: ${APP_PORT:-80}:80, Vite: ${VITE_PORT:-5173}
  • DB: ${FORWARD_DB_PORT:-3306}:3306
• .env.example alignment for Sail:
  • DB_HOST=mariadb, DB_USERNAME=sail, DB_PASSWORD=password (example defaults)
• Docs snippet in README for running with ./vendor/bin/sail or docker compose

What’s NOT included

• No database schema changes
• No changes to create/update logic
• No queue/scheduler services (can be added later)
