Dockerfile Template

This Dockerfile includes an example of using statements with 'if/else' conditions:

# Use an official Python runtime as a parent image
FROM python:3.8-slim

# Set the working directory in the container
WORKDIR /usr/src/app

# Copy the current directory contents into the container at the working directory
COPY . .

# Install any needed packages specified in requirements.txt
RUN pip install --no-cache-dir -r requirements.txt

# Make port 80 available to the world outside this container
EXPOSE 80

# Define environment variable
ENV NAME World

# Run app.py when the container launches
CMD ["python", "app.py"]

# Example if/else statement usage
RUN if [ "$ENV" = "production" ]; then \
        echo "Running in production mode"; \
    else \
        echo "Running in development mode"; \
    fi
