+FROM tiangolo/uvicorn-gunicorn-fastapi:python3.10-slim
+
+# Set the working directory inside the container
+WORKDIR /app

+# Copy the dependency and data files first
+COPY requirements.txt .
+COPY knowledge_base.json .

+# Install the Python libraries from the requirements file
+RUN pip install --no-cache-dir --upgrade pip && \
+    pip install --no-cache-dir -r requirements.txt
+
+# Copy the main application code
+COPY main.py .
+
+# The base image (uvicorn-gunicorn-fastapi) automatically knows
+# how to find and run the 'app' object from 'main.py' on port 8000.
+# So, no CMD or EXPOSE instruction is needed.
