What is Python

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.

How to use this image

Create a Dockerfile in your python app project.

FROM python:3
ADD . /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
ADD . /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

Run a single python script.

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
