title: Should Airflow and Jupyter be decoupled to 2 dockers
body: <p>The airflow is to schedule python and jupyter jobs.
  There are environment settings, directories and installed python and linux packages used by the python code.
  Should airflow be installed in a separate docker or in the same docker?
  If it is in a separate docker, how can the env, directories, installed packages be shared to the airflow?</p>
