我们可以使用 --user / -u 在 docker 容器中运行 jupyter lab

Question

我正在尝试将 jupyter-lab 添加到我现有的 docker 映像之一（带有 R、python 和特定于工作的库）以进行交互式测试。

一个有效的示例是这个 Dockefile：

FROM my_existing_image

# Install jupyter lab (assuming python3 and pip3 already installed)
RUN pip3 install jupyterlab

# Declare port used by jupyter-lab
EXPOSE 8888

# Set default command
CMD ["jupyter", "lab", "--port=8888", "--no-browser", "--ip=0.0.0.0", "--allow-root"]

但是，我们有一个共享 NFS 驱动器，我们将其安装在/mnt/NAS. 要以正确的权限从 docker 容器访问共享文件夹，我们通常使用以下标志启动它们：

docker run -u $(id -u ${USER}):$(id -g ${USER}) -v /mnt:/mnt my_image

但是，-u( --user) 选项会阻止 juyter-lab 正常启动，并且我收到以下错误消息：

Traceback (most recent call last):
  File "/usr/local/lib/python3.7/dist-packages/traitlets/traitlets.py", line 528, in get
    value = obj._trait_values[self.name]
KeyError: 'runtime_dir'

During handling of the above exception, another exception occurred:

我无法找到配置 Dockerfile 来访问驱动器和 jupyter-lab 工作的正确方法。我们经常以同样的方式使用Rocker/Rstudio容器，没有任何问题。

您有什么建议吗？感谢您的帮助。

我收到了相同的错误消息，因为容器的 $HOME 变量是 root /，如果没有sudo.

所以，对我来说，解决方案是将 $HOME 设置为指向可写目录。例如，

mkdir ./.home  # make a virtual home directory
docker run \
    -u $(id -u):$(id -g) -v $(pwd):$(pwd) -w $(pwd) -e HOME=$(pwd)/.home \
    -it --rm --init -p 8888:8888 your_image \
    jupyter lab --ip=0.0.0.0 --port=8888 --no-browser
