如何初始化Jupyterhub/Jupyterlab中notebook/工作目录的内容？

# ~/.jupyter/jupyter_notebook_config.py
import os

# 设置默认的工作目录
c.NotebookApp.notebook_dir = '/path/to/your/notebook/directory'

# 初始化工作目录的内容
def initialize_notebook_directory():
    notebook_dir = c.NotebookApp.notebook_dir
    if not os.path.exists(notebook_dir):
        os.makedirs(notebook_dir)
        with open(os.path.join(notebook_dir, 'README.md'), 'w') as f:
            f.write('# Welcome to your Jupyter Notebook Environment\n')

initialize_notebook_directory()

#!/bin/bash

NOTEBOOK_DIR="/path/to/your/notebook/directory"

if [ ! -d "$NOTEBOOK_DIR" ]; then
    mkdir -p "$NOTEBOOK_DIR"
    echo "# Welcome to your Jupyter Notebook Environment" > "$NOTEBOOK_DIR/README.md"
fi

FROM jupyterhub/jupyterhub:latest

USER root

# 创建工作目录并初始化内容
RUN mkdir -p /home/jovyan/work && \
    echo "# Welcome to your Jupyter Notebook Environment" > /home/jovyan/work/README.md

USER jovyan

chmod -R 755 /path/to/your/notebook/directory
chown -R jovyan:jovyan /path/to/your/notebook/directory

# ~/.jupyter/jupyter_notebook_config.py
c.NotebookApp.notebook_dir = '/path/to/your/notebook/directory'
