What is Docker and how can I use it with Python?

Docker is a platform that allows you to automate the deployment of applications in lightweight containers. You can use it with Python to create isolated environments for your applications.

How do I create a Dockerfile for my Python app?

To create a Dockerfile for your Python app, start with a base image like python:3.9. Then, copy your application files, install dependencies, and specify the command to run your app.

Can you give me an example of a simple Dockerfile?

Sure! Here's a simple Dockerfile:

FROM python:3.9
WORKDIR /app
COPY . .
RUN pip install -r requirements.txt
CMD ["python", "app.py"]

This sets up a Python environment, installs dependencies, and runs your app.

How do I build and run the Docker container?

You can build the Docker container using the command docker build -t my-python-app . and run it with docker run my-python-app.
