Using python

Running the Python Read-Eval-Print Loop (REPL)

The Python interpreter is the default command running in this image. Typing an end-of-file character (Control-D on Linux, Control-Z on Windows) causes the interpreter to exit. You can also exit the interpret by typing in the command: quit().

docker run -it --rm \
  docker.io/polymathrobotics/python:3.8-focal

Run a single Python script

For single file projects, you can run a Python script by using the container image directly:

docker run -it --rm \
  --mount type=bind,source="$(pwd)",target=/usr/src/myapp \
  --workdir /usr/src/myapp \
  docker.io/polymathrobotics/python:3.8-jammy python your-script.py

Create a Containerfile in your Python app project

FROM docker.io/polymathrobotics/python:3.8-jammy

WORKDIR /usr/src/app

COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

CMD [ "python", "./your-daemon-or-script.py" ]
