python - 如何使用带有 .devcontainer.json 的 Docker 在 VSCode 中启动 jupyter lab

Question

我正在尝试在由 Docker 封装的 VSCode 远程服务器中启动 jupyter 实验室，但出现错误提示

无法为内核 Python 3.8.5 64 位启动会话。选择另一个内核来启动。

我在工作区目录中设置了 Dockerfile 和 .devcontainer.json。我是否还需要 docker-compose.yaml 文件来进行 jupyter 实验室设置（如端口转发）？或者我可以用 .devcontainer.json 文件处理和替换 docker-compose 文件？

Dockerfile：

FROM python:3.8
RUN apt-get update --fix-missing && apt-get upgrade -y
# Set Japanese UTF-8 as locale so Japanese can be used
RUN apt-get install -y locales \
    && locale-gen ja_JP.UTF-8

ENV LANG ja_JP.UTF-8
ENV LANGUAGE ja_JP:ja
ENV LC_ALL ja_JP.UTF-8

# RUN apt-get install zsh -y && \
#     chsh -s /usr/bin/zsh

# Install zsh with theme and some plugins
RUN sh -c "$(wget -O- https://raw.githubusercontent.com/deluan/zsh-in-docker/master/zsh-in-docker.sh)" \
    -t mrtazz \
    -p git -p ssh-agent

RUN pip install jupyterlab
RUN jupyter serverextension enable --py jupyterlab
