Configure Jupyte Notebook Permissions

Things on this page are fragmentary and immature notes/thoughts of the author. Please read with your own judgement!

1. umask in /etc/profile or /etc/bashrc doesn’t work in docker, which is strange. Changing UMASK 022 in /etc/login.defs doesn’t work either ...

Had issues, tried to set /etc/profile, /etc/bashrc, in an init script, none of them worked worked well, For JupyterHub, you can configure in the *.py file jupyterhub/jupyterhub#1402

2. setfacl, getfacl, umask all are useful ...

setfacl, etc. works partially, there is currently a bug in jupyter notebook and I have file a issue on GitHub for them for fix it.

3. inotify can be used as a temporary solution

   #!/bin/bash dir=/jupyter inotifywait -m -r -e create --format ‘%w%f’ “$dir" | while read f; do if [[ -d "$f” ]]; then chmod 775 “$f” fi done
