🚀 Key Features

• Zero-Config Dev Mode: Works with any existing .env file. No forced variable naming.
• Smart Framework Detection: Auto-detects Vite (port 5173), Next.js (port 3000), or CRA.
• Flexible Deployment: SSH Build (default) or Registry Push — you choose.
• Production-Grade Defaults:
  • Non-root users, unprivileged Nginx
  • Healthchecks, restart policies
  • Multi-stage builds, .dockerignore generation

📦 Deployment Strategies

SSH Build (Default — No Registry Needed)

deployfilegen init --mode prod --deploy ssh

Required .env (only 2 variables!):

DEPLOY_HOST=your_server_ip
DEPLOY_USER=ubuntu

CI/CD workflow: SSH → git pull → docker compose build → up -d

Registry Push (Advanced — Immutable Deployments)

deployfilegen init --mode prod --deploy registry

Required .env:

# Always required
DEPLOY_HOST=your_server_ip
DEPLOY_USER=ubuntu

# Only for --deploy registry
DOCKER_USERNAME=your_username
BACKEND_IMAGE_NAME=user/backend
FRONTEND_IMAGE_NAME=user/frontend

CI/CD workflow: Build → Push to Registry → SSH → docker compose pull → up -d

🛠 Supported Stacks

Component	Framework	Auto-Detected
Backend	Django	Project name from manage.py
Frontend	Vite	Port 5173, --host binding
Frontend	Next.js	Port 3000, -H binding
Frontend	CRA	Port 3000, HOST env

---

⚙️ Configuration

Generate a boilerplate .env:

deployfilegen template                    # SSH mode (minimal)
deployfilegen template --deploy registry  # Registry mode (full)

🔧 Troubleshooting

"Missing required variables" error in prod mode?

deployfilegen template              # SSH: just DEPLOY_HOST + DEPLOY_USER
deployfilegen template --deploy registry  # Registry: adds DOCKER_USERNAME + IMAGE_NAMEs

Frontend container exits immediately?

deployfilegen init --mode dev --start-command "serve" --force

Wrong port detected?

deployfilegen init --mode dev --frontend-port 8080 --force

Django project name wrong?

deployfilegen init --mode prod --project-name my_project --force
