Docker Compose Environment Generator

Generate a Docker Compose configuration for the following development environment:

Project Overview

• Build Context: [. / ./backend / ./app / custom path]
• Dockerfile: [Dockerfile.dev / Dockerfile / custom name]
• Port Mapping: [e.g., 3000:3000, 8080:8080]
• Hot Reload: [Yes with volume mounting / No]
• Start Command: [npm run dev / python manage.py runserver / go run main.go / custom]

Database Services

Select required databases (can choose multiple):

Primary Database

• Type: [PostgreSQL / MySQL / MongoDB / Redis / CouchDB / None]
• Version: [Latest / Specific version]
• Port: [Default / Custom port]
• Initial Database Name: [Specify name]
• Credentials: [user/pass or use defaults]
• Initialization Scripts: [Yes, provide path / No]
• Data Persistence: [Named volume / Bind mount / None]

Additional Databases

• Secondary Database: [Redis for caching / Elasticsearch for search / None]
• Version: [Latest / Specific]
• Configuration: [Default / Custom config file]

Supporting Services

Select additional services needed:

Caching Layer

• Service: [Redis / Memcached / None]
• Configuration: [Default / Custom redis.conf]

Message Queue

• Service: [RabbitMQ / Kafka / NATS / None]
• Management UI: [Enable / Disable]

Reverse Proxy/Load Balancer

• SSL/TLS: [Local certificates / None]

Monitoring & Logging

• Logging: [Logstash / Fluentd / None]
• Metrics: [Prometheus / Grafana / None]
• Tracing: [Jaeger / Zipkin / None]

Service Dependencies

Define service startup order and dependencies:

• [e.g., app depends on: db, redis]
• [e.g., nginx depends on: app]
• [List other dependencies]

Volume Configuration

• Application Code: [Bind mount for hot reload / Copy to container]
• Database Data: [Named volumes / Bind mounts]
• Persistent Storage: [Additional volumes needed: [LIST] / None]
• Exclude Patterns: [node_modules, pycache, .git, etc.]

Environment Variables

Define environment variables for each service:

App Service Variables

• [e.g., NODE_ENV=development]
• [e.g., DATABASE_URL=postgresql://user:pass@db:5432/dbname]
• [e.g., REDIS_URL=redis://redis:6379]
• [Add more as needed]

Database Variables

• [e.g., POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DB]
• [Add others as needed]

Health Checks

• Enable Health Checks: [Yes / No]
• App Health Check: [HTTP endpoint / TCP check / Custom command]
• Database Health Check: [pg_isready / mysqladmin ping / Custom]
• Check Intervals: [Default / Custom timing]

Network Configuration

• Network Setup: [Single default network / Multiple networks / Custom]
• Network Isolation: [Frontend/Backend separation / All connected / Custom]
• External Access: [Expose all services / Only app / Selective]

Development Features

• Hot Reload: [Enabled with volume mounts / Disabled]
• Debug Ports: [Expose debug ports: [SPECIFY] / No]
• Test Environment: [Separate docker-compose.test.yml / Integrated / None]
• Seed Data: [Initialize with seed data / Empty start]

Resource Limits

• Memory Limits: [Set limits per service / Unlimited]
• CPU Limits: [Set limits / Unlimited]
• Storage Limits: [Set quotas / Unlimited]

Additional Configuration

• Docker Compose Version: [3.8 / 3.9 / Latest]
• Override Files: [docker-compose.override.yml / docker-compose.prod.yml / Custom]
• Profiles: [Use profiles for optional services / No]

Platform-Specific Requirements

• Target OS: [Linux / macOS / Windows / Cross-platform]
• Architecture: [amd64 / arm64 / Both]

Generate a complete Docker Compose setup including:

• Main docker-compose.yml file with all services configured
• Dockerfile.dev (or appropriate Dockerfile) for application service
• Volume definitions for data persistence
• Network configuration
• Environment variable setup
• Health checks for services
• Service dependencies with depends_on
• Port mappings for all services
• README with common commands:
  • Start services: docker-compose up
  • Start in background: docker-compose up -d
  • View logs: docker-compose logs -f [service]
  • Stop services: docker-compose down
  • Rebuild: docker-compose up --build
  • Execute commands: docker-compose exec [service] [command]
• Optional override file for testing (docker-compose.test.yml) if testing environment is needed

Output production-ready configuration optimized for development workflow with fast startup times and proper isolation.
