Toolkit

• Docker Desktop
  You have to create a docker hub account

• Docker Documentation

• WSL - (Win user only) - Optional
  Ubuntu 16.04 should be fine, but I suggest you to start with 18.04 instead.
  Someone had issue installing docker-compose via python. Installing it via curl works just fine.
  WSL provides a full linux bash experience. Win users not using WSL have to adapt some commands within this tutorial and convert some scripts to the target terminal language.
