Django shell_plus:如何在 Docker 容器中访问 Jupyter notebook

Django shell_plus: How to access Jupyter notebook in Docker Container

我正在尝试从 Docker 容器中的 django-extensions 访问使用 shell_plus 命令创建的 Jupyter Notebook。

docker-compose -f local.yml run --rm django python manage.py shell_plus --notebook

我的配置基于@RobM 和@Mark Chackerian 对此 的回答。 IE。我安装并配置了一个自定义内核,我的 Django 应用程序配置文件将常量 NOTEBOOK_ARGUMENTS 设置为:

NOTEBOOK_ARGUMENTS = [
    '--ip', '0.0.0.0',
    '--port', '8888',
    '--allow-root',
    '--no-browser',
]

我可以在日志中看到容器成功启动:

[I 12:58:54.877 NotebookApp] The Jupyter Notebook is running at:
[I 12:58:54.877 NotebookApp] http://10d56bab37fc:8888/?token=b2678617ff4dcac7245d236b6302e57ba83a71cb6ea558c6
[I 12:58:54.877 NotebookApp]  or http://127.0.0.1:8888/?token=b2678617ff4dcac7245d236b6302e57ba83a71cb6ea558c6

但是我打不开 url。我在 docker-compose 中转发了端口 8888,尝试使用 localhost 而不是 127.0.0.1 并且还尝试使用容器 IP w/o 成功。

感觉我在这里遗漏了明显的东西……感谢任何帮助。

它可以正常工作,但我不明白为什么会这样。在 docker-compose run 命令中公开端口就成功了。

docker-compose -f local.yml run --rm -p 8888:8888 django python manage.py shell_plus --notebook

我的印象是,在 local.yml 中公开端口也会在 run 启动的容器中打开它们。

为了截至 2020 年的记录,我设法在 docker-compose 中使用 Postgresql 进行了工作 django 设置:

development.py (settings.py)

INSTALLED_APPS += [
    "django_extensions",
]

SHELL_PLUS = "ipython"

SHELL_PLUS_PRINT_SQL = True

NOTEBOOK_ARGUMENTS = [
    "--ip",
    "0.0.0.0",
    "--port",
    "8888",
    "--allow-root",
    "--no-browser",
]

IPYTHON_ARGUMENTS = [
    "--ext",
    "django_extensions.management.notebook_extension",
    "--debug",
]

IPYTHON_KERNEL_DISPLAY_NAME = "Django Shell-Plus"

SHELL_PLUS_POST_IMPORTS = [ # extra things to import in notebook
    ("module1.submodule", ("func1", "func2", "class1", "etc")),
    ("module2.submodule", ("func1", "func2", "class1", "etc"))

]

os.environ["DJANGO_ALLOW_ASYNC_UNSAFE"] = "true" # only use in development

docker-compose.yml

version: "3"

services:
  db:
    image: postgres:13
    environment:
      - POSTGRES_HOST_AUTH_METHOD=trust
    restart: always
    ports:
      - "5432:5432"
    volumes:
      - postgres_data:/var/lib/postgresql/data/
  web:
    build: .
    environment:
      - DJANGO_SETTINGS_MODULE=settings.development
    command:
      - scripts/startup.sh
    volumes:
      - ...
    ports:
      - "8000:8000" # webserver 
      - "8888:8888" # ipython notebook
    depends_on:
      - db

volumes:
  postgres_data:

从您的主机终端 运行 此命令:

docker-compose exec web python manage.py shell_plus --notebook

最后在主机的网络浏览器中导航到 http://localhost:8888/?token=<xxxx>

如果你想像分离服务一样使用jupyter notebook:

jupyter_notebook:
  build:
    context: .
    dockerfile: docker/dev/web/Dockerfile
  command: python manage.py shell_plus --notebook
  depends_on:
    - web
  ports:
  - 8888:8888 # ipython notebook
  env_file:
    - .env

之后:

docker-compose logs -f 'jupyter_notebook'

您将在日志中获得访问令牌

compose 运行 命令默认不会公开定义的服务端口。来自 https://docs.docker.com/compose/reference/run/

的文档

The [...] difference is that the docker-compose run command does not create any of the ports specified in the service configuration. This prevents port collisions with already-open ports. If you do want the service’s ports to be created and mapped to the host, specify the --service-ports flag:

docker-compose run --service-ports web python manage.py shell 

因此您需要运行

docker-compose -f local.yml run --rm --service-ports django python manage.py shell_plus --notebook

也可能是默认的 8888 端口已被本地 jupyter 服务器使用(例如,由 VS Code 的 jupyter notebook 实现启动。因此我通常映射到 settings.py NOTEBOOK_ARGUMENTS list. (此时compose文件中的端口映射也需要调整,当然,后台不能有另一个容器运行ning和这个服务定义相同也可能占用端口。)
