[Bit-dev] Docker: Python 3.6, git and Bash

Hello Folks, is someone able to deal with Docker? I'm not experienced here but now how to install it on Debian and how to run a Python REPL with a specific Python version. I install on Debian 11 sudo apt install docker docker.io Then I run the container sudo docker run -it --rm python:3.6 Now where I need help. I don't want to run the REPL. I want to begin in a bash shell because I need to do "git clone" (or mounting something from host?) and need to run unittest scripts. Has anyone a tip for me? I assume my problems root in the fact that I lack of deeper understanding of Docker concept and its UI. Kind Christian
