How can I use Docker with Python?

You can use Docker to create a container for your Python application, which helps in managing dependencies and environments.

What are the basic steps to create a Dockerfile for a Python app?

First, you need to create a Dockerfile that specifies the base image, copies your application code, installs dependencies, and sets the command to run your app.

Can you provide an example of a simple Dockerfile for a Flask app?

Sure! Here's a simple Dockerfile:

FROM python:3.8

WORKDIR /app

COPY requirements.txt .
RUN pip install -r requirements.txt

COPY . .

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

This sets up a Flask app in a Docker container.

How do I build and run the Docker container?

You can build the container using docker build -t my-flask-app . and run it with docker run -p 5000:5000 my-flask-app.
