FROM python:3.9-slim-buster

WORKDIR /app

COPY requirements.txt .

RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD ["python", "your_genai_app.py"]

This Dockerfile starts with a base Python image, sets the working directory, copies the requirements file, installs dependencies, copies the application code, and finally, defines the command to run your GenAI application (your_genai_app.py).

Step 2: Define Your Requirements

Create a requirements.txt file listing all your project’s Python dependencies:



tensorflow==2.11.0

numpy

pandas

# Add other necessary libraries here

Step 3: Build the Docker Image
