发现哪个内核已经启动 [英] discovering which kernel has been started
问题描述
环境:我正在Docker容器中生成Notebook服务器(版本5)，并且拥有一个系统，用户可以在其中选择他们希望启动的多个Notebook内核之一(因此，Docker映像).
Environment : I am spawning Notebook Servers (version 5) in Docker Containers, and have a system where users may select one of several Notebook kernels (thus, docker images) they wish to start.
我需要在笔记本服务器页面上添加一个指示器，以指示已启动了哪个特定内核.
I have a need to add an indicator to the notebook server page to indicate which particular kernel has been started.
我已经有修改page.html和tree.html模板的模板，因此可以将我需要的内容添加到 html 没问题....我无法解决的问题是我如何从Docker容器获取一些数据到Notebook Server渲染代码.
I already have templates that modify the page.html and tree.html templates, so can add whatever I need into the html no problem.... what I'm failing to work out is how I get some piece of data from the Docker Container to the Notebook Server rendering code.
我推断这可能是通过向jupyter_notebook_config.py文件中添加一些内容而实现的-但找不到任何方法可以帮助您.
I'm deducing that it will probably be by adding something to the jupyter_notebook_config.py file - but can't find anything to help either way.
有人这样做吗?
推荐答案
感谢Jupyter开发人员...我有一个解决方案:
With thanks to the Jupyter development peoples... I have a solution:
在jupyter_notebook_config.py中，您可以设置一个字典:
In jupyter_notebook_config.py you can set a dict:
c.NotebookApp.jinja_template_vars = {'Ian_1':'One','ian_2':'Two'}
读取模板中的数据
在您的Jinja模板文件中，可能有一个获取参数的块.在tree.html中，它看起来像这样:
Reading data in the templates
In your Jinja template file, there's probably a block for getting parameters. In tree.html it looks like this:
{% block params %}
{{super()}}
data-base-url="{{base_url | urlencode}}"
data-notebook-path="{{notebook_path | urlencode}}"
data-terminals-available="{{terminals_available}}"
data-server-root="{{server_root}}"
{% endblock %}
您需要做的所有事情都会添加到变量中(显然，它们是区分大小写的)....例如:
All you need to do it add in your variables (obviously, they are case-sensitive).... eg:
{% block params %}
{{super()}}
data-base-url="{{base_url | urlencode}}"
data-notebook-path="{{notebook_path | urlencode}}"
data-terminals-available="{{terminals_available}}"
data-server-root="{{server_root}}"
ian_1="{{ian_1}}"
ian_2="{{ian_2}}"
{% endblock %}
(请注意Ian_1的大小写不正确)
(note the incorrect case-match for Ian_1)
现在，如果您在笔记本中查看/tree页面的源代码，则会在body标记的属性中找到它们:
if you now look at the source code of the /tree page in your notebook, you'll find them as attributes to the body tag:
<body class=""
data-jupyter-api-token="<token-string>"
data-base-url="/"
data-notebook-path=""
data-terminals-available="True"
data-server-root="/home/jovyan"
ian_1=""
ian_2="Two"
dir="ltr">
(请注意，由于大小写不匹配，ian_1为空白.)
(and note that ian_1 is blank due to the case mis-match.)
您现在可以将变量用作Jinja中的任何其他变量(根据 http://jinja.pocoo.org /)
You can now use the variable as any other variable in Jinja (as per http://jinja.pocoo.org/)
