Always complains "You aren’t in a git repository" after launching juputerlab from jupyterhub

My notebook_url is set to /home/admin, and when admin logged in, it is automatically navigated to /home/admin as default. I’ve tried to create a new gitlab repo and apply /home/admin to this git repo after commands like (git init; git add .; git commit -m '...'; git push origin master). After all these done, the directory looks as below:

[root@9b27d6147671 admin]# pwd
/home/admin
[root@9b27d6147671 admin]# ll -a
total 40
drwxrwx---  8 admin admin 4096 Aug 16 18:56 .
drwxr-xr-x 14 root  root  4096 Aug 16 18:33 ..
-rw-------  1 admin admin   56 Aug 16 19:10 .bash_history
drwx------  3 admin admin 4096 Aug 16 18:55 .config
drwxr-xr-x  7 admin admin 4096 Aug 16 19:16 .git

I launched jupyterhub from path ‘/’ via command jupyterhub --port 8080 and the git extension always complains “You aren’t in a git repository” even though the git repo exists there. Any ideas? Thanks.

I finally got it working in my docker build. For me the secrets were 1) ensuring I ran jupyter labextension link and 2) making sure my serverextension command included --sys-prefix jupyterlab_git

Below is my docker file excerpt showing how I’m loading jupyterlab-git. Note that I’m cloning from github and doing a checkout at a specific hash just to ensure nothing changes underneath me over time.

RUN git clone https://github.com/jupyterlab/jupyterlab-git 
WORKDIR ./jupyterlab-git
RUN git checkout 276a42d772e0a13eb4b880c1ea45044cd5821a45
RUN npm install 
RUN npm run build
RUN jupyter labextension link . 
RUN npm run build 

RUN pip3.6 install .
RUN jupyter serverextension enable --py --sys-prefix jupyterlab_git

Same with jupyterlab 0.35.2, but:

• no more error on jupyterlab start (jupyterlab_git pypi module seem well installed)
• 404 still returned on the git/all_history endpoint. The log displays:

404 POST /staging/user/myusername/git/all_history?1540396029715 (myusername@12.13.14.15) 30.64ms

I am behind a jupyterhub + jupyterlab, and the url is accessible throught: http://jupyter.mycompany.fr/staging/user/myusername/lab
