Permission denied error

[larrycai]

In one old docker server, I got permission error "Permission denied: Untitled.ipynb"

• docker version: 1.13.1 (can't change so far)
• docker host server: Ubuntu 16.04

error from console is

[I 13:41:04.238 NotebookApp] Creating new notebook in
...
[W 13:43:19.126 NotebookApp] 403 GET /api/sessions?_=1527255637897 (x.x.x.x) 1.60ms referer=http://x.x.x.x:8888/tree?
[W 13:43:19.135 NotebookApp] Forbidden

While it works fine in my local docker @ Windows 7

• docker version: 18.01.0-ce

Hi @larrycai,

Could you show me the result of the below cmd?

$ docker exec <container_id> ls -ld /code

[larrycai]

The success one is

/code # ls -ld
drwxrwxrwx    1 docker   50               0 May 27 20:16 .

The failure one is

/code # ls -ld
drwxr-xr-x    2 root     root          4096 May 27 20:12 .

UPDATE, when I try again for failure one, it is

drwxrwxr-x    2 docker   docker        4096 May 28 06:59 .

@larrycai
hmm, Do you use workdir not /code but any other directory or don't use local volume mount option?

[larrycai]

I mounted the folder from host to /code , like -v $PWD/scikit:/code, I guess it is a bug/permission issue in Dockerfile, which I met before.

I will also try to see whether I can provide patch to fix it.

I am not sure whether you can add jupyter into docker group as well, I tested below works

FROM smizy/scikit-learn
RUN addgroup jupyter docker
ENTRYPOINT ["/sbin/tini", "--", "entrypoint.sh"]
CMD ["jupyter", "notebook"]

[smizy]

I fixed in another branch "fix_permission_denied" without rebuilding dependency libs. And docker image tag "smizy/scikit-learn:0.19.1-alpine-r1". Please give it a try.
