如何从 Dask Jupyter 笔记本中持久化笔记本？

Question

I am running a Docker compose file ( docker-compose up --force-recreate ) to start Dask scheduler, workers, and the Dask Jupyter notebook. I have added volumes as follows:

  notebook:
    image: daskdev/dask-notebook
    depends_on:
      - scheduler
      - worker
    ports:
      - "8888:8888"
    environment:
      DASK_SCHEDULER_ADDRESS: "tcp://scheduler:8786"
    volumes:
      - "~/Personal/python-workspace/notebooks:/home/jovyan/work"
      - "~/Personal/docker-volumes/tmp:/tmp"

Whenever I try to create a file under the work folder, I get an HTTP 403 with the following logs in the terminal:

notebook_1   | [I 03:28:19.584 LabApp] Saving file at /Untitled.ipynb
notebook_1   | [I 03:28:35.668 LabApp] Creating new file in /work
notebook_1   | [W 03:28:35.670 LabApp] Permission denied: work/untitled.txt

How do I go about resolving this and persisting my notebooks?

Answer 1

On the host (outside the docker container), this should work and allow you to avoid this Denied error :

sudo chmod -R 777 ~/Personal/python-workspace/notebooks

But that's not the correct way to fix the error and since daskdev/dask-notebook is based on jupyter/base-notebook you should refer to this documentation :

Refering to this URL, I think adding these environment variables in your docker-compose file should help fix your issue without having to use a command such as chmod :

• CHOWN_HOME=yes
• CHOWN_HOME_OPTS='-R'
