Docker Compose Development Generator

Generates complete Docker Compose development configurations for PHP projects with database, cache, queue, mail, and debugging services.

Generated Files

docker-compose.yml        # Full development stack
.env.docker               # Environment variables for Docker

Generation Instructions

1. Analyze project: Read

   composer.json

   for database drivers, Redis, RabbitMQ, Elasticsearch; detect framework
2. Select services: PHP-FPM + Nginx (always), DB (MySQL/PostgreSQL), Redis, RabbitMQ (profiles), Mailhog (profiles)
3. Generate: All services with health checks, networking, env vars, profiles for optional services

Profile Usage

# Core services only (PHP, Nginx, DB, Redis)
docker compose up -d

# With RabbitMQ
docker compose --profile queue up -d

# With Mailhog
docker compose --profile mail up -d

# All services
docker compose --profile queue --profile mail up -d

Common Development Commands

# First-time setup
docker compose up -d --build
docker compose exec php composer install
docker compose exec php php bin/console doctrine:migrations:migrate

# Daily workflow
docker compose up -d
docker compose exec php vendor/bin/phpunit
docker compose exec php vendor/bin/phpstan analyse

# Cleanup
docker compose down
docker compose down -v  # Also remove volumes

Additional Services

See

references/service-templates.md

for composable service blocks: MySQL, Elasticsearch, MinIO, phpMyAdmin, Adminer, Traefik.

Usage

Provide:

• Database type (PostgreSQL/MySQL)
• Required services (Redis, RabbitMQ, Mail)
• Framework (Symfony/Laravel)
• Custom ports (optional)

The generator will:

1. Create docker-compose.yml with selected services
2. Generate Nginx configuration
3. Create .env.docker with all variables
4. Add health checks and configure networking
