Jupyter notebook on Docker - permission denied

Question

I have a Docker container running on a remote computer, which is mapped to port 3000 and root folder /data : When accessing root folder with Jupyter notebook, I get the following error message:

Server error: Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/tornado/web.py", line 1704, in _execute result = await result File "/usr/local/lib/python3.7/site-packages/tornado/gen.py", line 234, in wrapper yielded = ctx_run(next, result) File "/usr/local/lib/python3.7/site-packages/notebook/services/contents/handlers.py", line 112, in get path=path, type=type, format=format, content=content, File "/usr/local/lib/python3.7/site-packages/notebook/services/contents/filemanager.py", line 437, in get model = self._dir_model(path, content=content) File "/usr/local/lib/python3.7/site-packages/notebook/services/contents/filemanager.py", line 311, in _dir_model for name in os.listdir(os_dir): PermissionError: [Errno 13] Permission denied: '/data'

Other directories work, except root (ie I can access /data/abc/). Notebooks work. Notebook ver.: 4.4.0 Ubuntu 16.04

Answer 1

One of the other users on the network made some modifications and messed up permission rights, it looks like it can be done like this:

sudo chmod 777 /data

and the Permission denied warning disappears..
