Production & Docker

Fastman makes it easy to prepare your application for production.

Building for Production​

Run the build command to run tests and type checks:

fastman build

Docker Support​

Fastman can automatically generate a Dockerfile and build an image for you.

fastman build --docker

This will:

  1. Create a production-ready Dockerfile (if missing).
  2. Build the image using your project name.

Generated Dockerfile​

The generated Dockerfile is optimized for python 3.11-slim:

FROM python:3.11-slim

WORKDIR /app

# Install dependencies
COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

# Copy application
COPY . .

# Run migrations and start server
CMD ["sh", "-c", "alembic upgrade head && uvicorn app.main:app --host 0.0.0.0 --port 8000"]

Configuration Caching​

In production, parsing .env files can be slow. Use config caching to speed up boot time.

fastman config:cache

This creates a config_cache.json file that Fastman loads instantly.
