Python is a widely used general-purpose, high-level programming language. Its design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than would be possible in languages such as C. The language provides constructs intended to enable clear programs on both a small and large scale.
FROM python:3
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "python", "./your-daemon-or-script.py" ]
or (if you need to use Python 2):
FROM python:2
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "python", "./your-daemon-or-script.py" ]
Then build and run the docker image.
docker build -t my-python-app
docker run -it --rm --name my-running-app my-python-app
For many single file projects, it may not be convenient to write a Dockerfile for your project. In such cases, you can run a python script by using the python docker image directly.
docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp python:3 python your-daemon-or-script.py
or (again, if you need to use Python 2):
docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp python:2 python your-daemon-or-script.py

You are invited to contribute new features, fixes, or updates, large or small; we are always thrilled to receive pull requests, and do our best to process them as fast as we can.
Before you start to code, we recommend discussing your plans through a GitHub issue, especially for more ambitious contributions. This gives other contributors a chance to point you in the right direction, give you feedback on your design, and help you find out if someone else is working on the same thing.
