HowTo build a Docker Image

... for my python experiments

• Use the latest ubuntu docker-image from hub.docker.com

  • because I need the recent libolm3 and libolm-dev
• I need to

  * apt update
  * apt install python3-venv libolm-dev emacs-nox build-essential python3-pip python3-openssl ffmpeg
  * adduser experiments --home /home/experiments --disabled-password
  * experiments:experiments | chpasswd
  * su -l experiments
    * mkdir /home/experiments/applications 
    * python3 -m venv /home/experiments/applications
    * source /home/experiments/applications/bin/activate

  I have to run

  python3 matrix-commander.py

  before it will work with my own script, because it needs to setup the storage with my login data and the room to post to.
