Question

我正在尝试使用JupyterLab

我想生成许多JupyterLab个实例，就像{Jupyter Notebook} tmpnb的方式一样。

我使用以下Dockerfile通过docker build -t jupyterlab2 .命令创建了一个新的docker镜像：

FROM jupyter/datascience-notebook
MAINTAINER apr
RUN pip install npm
RUN pip install jupyterlab
RUN jupyter serverextension enable --py jupyterlab

在此之后我运行以下命令：

export TOKEN=$( head -c 30 /dev/urandom | xxd -p )

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=proxy jupyter/configurable-http-proxy --default-target http://127.0.0.1:9999

docker run --net=host -d -e CONFIGPROXY_AUTH_TOKEN=$TOKEN --name=tmpnb -v /var/run/docker.sock:/docker.sock jupyter/tmpnb python orchestrate.py --allow_origin='*' --image='jupyterlab2' --pool-size=5 --container-user=root  --command='jupyter lab --allow-root LabApp.allow_origin="*"'

当我访问网址http://<ip-address>:8000时，我会被重定向到http://<ip>:8000/user/sTVKGwH01uoQ，但这会显示为404。我也试过访问http://<ip>:8000/user/sTVKGwH01uoQ/lab，但这也给了404。

1个实例的日志如下：

我看了an issue related to JupyterHub，看起来非常相似。 404错误页面对我来说也是一样的。我用start.sh尝试了一些随机的东西，但没有运气。

甚至可以使用tmpnb运行JupyterLab吗？如果不是，那么我可以使用的其他工具有哪些实现相同的目的？

Answer 1

必须设置基本URL，否则/user/...路由将不会映射到正确的内容。这是所有示例命令in the tmpnb README中的--NotebookApp.base_url={base_path}部分。这些看起来像：

python orchestrate.py --command='jupyter notebook --no-browser \
    --port {port} --ip=0.0.0.0 --NotebookApp.base_url={base_path} \
    --NotebookApp.port_retries=0'

所以JupyterLab等价物是：

python orchestrate.py --command='jupyter lab --no-browser \
    --port {port} --ip=0.0.0.0 --NotebookApp.base_url={base_path} \
    --NotebookApp.port_retries=0'

所有这些都适用于jupyterlab，所以你想要替换的唯一arg可能是notebook和lab。同时，您根本不需要更改默认命令，因为如果安装了实验室扩展，则在您启动/lab时，jupyter notebook URL会显示jupyterlab。您现在可以通过在任何现有tmpnb.org网址上将/tree替换为/lab来查看此内容。

使用Jupyter Lab和tmpnb
