Next set cache directory for singularity, go to that directory, and get the docker container for coffea-dask:

export SINGULARITY_CACHEDIR=/uscms_data/d2/<your_directory>/singularity/.singularity
cd /uscms_data/d2/<your_directory>/singularity
singularity shell -B ${PWD}:/work /cvmfs/unpacked.cern.ch/registry.hub.docker.com/coffeateam/coffea-dask:latest

From within the container, set the jupyter paths and start a server:

export JUPYTER_PATH=/work/.jupyter
export JUPYTER_RUNTIME_DIR=/work/.local/share/jupyter/runtime
export JUPYTER_DATA_DIR=/work/.local/share/jupyter
export IPYTHONDIR=/work/.ipython
jupyter notebook --ip 0.0.0.0 --no-browser --notebook-dir /work
