Dear All,

I use jupyter notebook server and kernel to execute python and r script on the fly using websocket.

I have created docker container using below command.

FROM jupyter/r-notebook:3b1f4f5e6cc1
USER root
RUN mkdir /opt/notebook_dir

COPY jupyter_notebook_config.py /home/$NB_USER/.jupyter/
COPY requirements.txt /home/$NB_USER/

RUN chown $NB_USER -R /home/$NB_USER
RUN chown $NB_USER -R /opt/notebook_dir

EXPOSE 8888
ENTRYPOINT [“tini”, “-g”, “–”]
CMD [“start-notebook.sh”]

RUN conda install --yes --file /home/$NB_USER/requirements.txt
RUN fix-permissions $CONDA_DIR

USER $NB_USER

But I notice after few hours all content is deleted under /home/jovyan folder. Any idea what is deleting all this files/folders?

Here is my jupyter_config file

c.NotebookApp.ip = ‘0.0.0.0’
c.NotebookApp.token = ‘’
c.NotebookApp.password = ‘’
c.NotebookApp.allow_origin = ‘*’
c.NotebookApp.disable_check_xsrf = True
c.NotebookApp.notebook_dir = ‘/opt/notebook_dir/’
c.NotebookApp.open_browser = False

Here is my requirements.txt file

matplotlib==3.2.1
numpy==1.18.4
pandas==1.0.3
scipy==1.4.1
scikit-learn==0.23.1
statsmodels==0.11.1
seaborn==0.10.1

Any help in this matter is highly appreciated. do let me know if you need any other information.

Is it possible your Docker container is being automatically shut down or restarted?

Thanks Manics,

In docker-compose I did mentioned restart always. I am not sure in what scenarios it automatically get shutdown/restarted. Even if it restart, i am not sure why it is deleting all content which were added during image build.

Is your full docker-compose.yml available to look at?
