                How I like to run my Jupyter notebooks
              
          
    Step 0. Install Docker
Step 1. For your chosen project, decide where you want to store your notebooks and files in a workingfolder.
Step 2. Open that folder in the terminal  cd workingfolder
Step 3. Run this command
docker run -it --rm -v $PWD:/home/jovyan/work -p 8888:8888 jupyter/all-spark-notebook
