📦 Docker Configuration

Your current Dockerfile has been optimized for the latest Python version and security best practices.

Updated `Dockerfile`:

# Use the official Python 3.12 slim image as the base
FROM python:3.12-slim

# Set environment variables to prevent Python from writing .pyc files and to ensure output is flushed
ENV PYTHONUNBUFFERED=1 \
    PYTHONDONTWRITEBYTECODE=1

# Set the working directory inside the container
WORKDIR /app

# Install system dependencies required for building Python packages
RUN apt-get update && apt-get install -y --no-install-recommends \
    build-essential \
    && rm -rf /var/lib/apt/lists/*

# Copy only the requirements file to leverage Docker cache
COPY requirements.txt /app/

# Upgrade pip and install Python dependencies globally
RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt

# Copy the rest of the application code into the container
COPY . /app

# Create a non-root user for better security
RUN useradd -m appuser

# Change ownership of the /app directory to appuser
RUN chown -R appuser:appuser /app

# Switch to the non-root user
USER appuser

# Expose port 8080 for Cloud Run (or any other target environment)
EXPOSE 8080

# Command to run the application with Uvicorn
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8080"]

Explanation of Changes:

Base Image Updated to Python 3.12:
```
FROM python:3.12-slim
```
- Why: Aligns the Docker environment with the Python version used in development (Python 3.12.2), reducing compatibility issues.
Environment Variables:
```
ENV PYTHONUNBUFFERED=1 \
    PYTHONDONTWRITEBYTECODE=1
```
- PYTHONUNBUFFERED=1: Ensures that Python outputs are immediately flushed to the terminal, useful for real-time logging.
- PYTHONDONTWRITEBYTECODE=1: Prevents Python from writing .pyc files to disk, saving space.
Working Directory:
```
WORKDIR /app
```
- Why: Sets /app as the working directory inside the Docker container. All subsequent commands are run from this directory.
System Dependencies Installation:
```
RUN apt-get update && apt-get install -y --no-install-recommends \
    build-essential \
    && rm -rf /var/lib/apt/lists/*
```
- build-essential: Installs essential build tools required for compiling certain Python packages.
- --no-install-recommends: Minimizes the number of packages installed, reducing the final image size.
- Cleanup: Removes the package lists to further reduce the image size.
Python Dependencies Installation:
```
COPY requirements.txt /app/
RUN pip install --upgrade pip
RUN pip install --no-cache-dir -r requirements.txt
```
- Why:
  - Copies requirements.txt to leverage Docker's caching mechanism.
  - Upgrades pip to the latest version.
  - Installs Python dependencies globally without the --user flag, ensuring executables like uvicorn are accessible system-wide.
Application Code Copy:
```
COPY . /app
```
- Why: Copies the entire application code into the Docker container.
Non-Root User Setup:
```
RUN useradd -m appuser
USER appuser
```
- Why: Enhances security by running the application as a non-root user.
File Ownership:
```
RUN chown -R appuser:appuser /app
```
- Why: Ensures that appuser has the necessary permissions to access and execute files within /app.
Port Exposure and Command:
```
EXPOSE 8080
CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8080"]
```
- Why:
  - Exposes port 8080 for Cloud Run or other deployment environments.
  - Starts the FastAPI application using Uvicorn, pointing to the correct application instance (app.main:app).

Ensure Correct Application Reference:

In your CMD instruction:

CMD ["uvicorn", "app.main:app", "--host", "0.0.0.0", "--port", "8080"]

app.main:app:
- app.main: Refers to the main.py file inside the app/ directory.
- app: Refers to the FastAPI instance inside main.py.

Ensure that your project structure aligns with this reference:

gcp-fastapi-api/
├── app/
│   ├── __init__.py
│   ├── main.py
│   ├── auth_google.py
│   ├── models/
│   │   ├── __init__.py
│   │   ├── claims.py
│   │   └── item.py
│   ├── routers/

│       └── storage_service.py
├── requirements.txt
├── Dockerfile
├── .dockerignore
└── README.md

📂 .dockerignore File

To optimize your Docker build process and reduce the final image size, create a .dockerignore file in your project root with the following content:

# Exclude Python cache files
__pycache__/
*.pyc
*.pyo
*.pyd

# Exclude environment variables
.env

# Exclude version control
.git
.gitignore

# Exclude Docker-related files
Dockerfile
docker-compose.yml

# Exclude documentation and miscellaneous files
*.md

Why: This ensures that unnecessary files and directories are not copied into the Docker image, making the build process faster and the image smaller.
