# Set the working directory in the container

# Install system dependencies that might be needed by Python packages
# Example: build-essential for some packages, libpq-dev for psycopg2 from source (though -binary avoids this)
# For psycopg2-binary, typically no extra system deps are needed for common platforms if using a compatible wheel.
# RUN apt-get update && apt-get install -y --no-install-recommends build-essential libpq-dev && rm -rf /var/lib/apt/lists/*

# Copy the requirements file into the container
COPY requirements.txt .

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

# Copy the application source code into the container
# This structure assumes your main application code is within the 'tensorus' directory.
COPY ./tensorus ./tensorus
# If your app.py or main.py is at the root alongside Dockerfile, you'd copy it too:
# COPY app.py . # Or specific main file if it's at the root.
# Based on `CMD ["uvicorn", "tensorus.api.main:app"...]`, main:app is in tensorus/api/main.py.

# Set default environment variables for the application
# These can be overridden when running the container (e.g., via docker run -e or docker-compose.yml)
