Unable to pass tornado_settings command line with a space.

[rwmajor2]

Trying to do the following:
docker run -it --rm myDockerimg:latest start-notebook.sh --NotebookApp.base_url=/turing/notebooks/f63e305a-539a-4487-b68d-6a147fafb6ee --NotebookApp.token=2VIKxSkcA8o6mEmaIFvQMSO6z1NQOT+txTjWYqk/dv8= --NotebookApp.notebook_dir=/mnt/arcgis --NotebookApp.tornado_settings="{'headers':{'Content-Security-Policy':'frame-ancestors self *.mydomain.com'}}"

I need to launch containers where the CSP could change dynamically, hence why I am not using a config file. However, that space in the tornado_settings is causing me a problem. I have tried numerous attemps of single quotes, double quotes, backslashes, etc. to no avail. Can anyone offer any suggestions?

Looking at the Docker logs, I see Jupyter say this:

Executing the command: jupyter notebook --NotebookApp.base_url=/turing/notebooks/f63e305a-539a-4487-b68d-6a147fafb6ee --NotebookApp.token=2VIKxSkcA8o6mEmaIFvQMSO6z1NQOT+txTjWYqk/dv8= --NotebookApp.notebook_dir=/mnt/arcgis --NotebookApp.tornado_settings={'headers':{'Content-Security-Policy':'frame-ancestors self'}}
The Jupyter HTML Notebook.

This launches a Tornado based HTML Notebook Server that serves up an
HTML5/Javascript Notebook client.

But then complains:

[C 15:56:20.505 NotebookApp] Bad config encountered during initialization:
[C 15:56:20.505 NotebookApp] The 'tornado_settings' trait of a NotebookApp instance must be a dict, but a value of class 'str' (i.e. "{'headers':{'Content-Security-Policy':'frame-ancestors") was specified.

It's technically possible with the right amount of quotes, but I would consider these settings to effectively require being set in a config file.

I have this problem too.And how can I fix it?

I've encountered the same issue. Did you figure it out?

So basically you can write this piece of code in your jupyter_config.py:
c.NotebookApp.tornado_settings = {'headers': { 'Content-Security-Policy': "frame-ancestors *YourDomain.com* 'self' ;",}}

However, if you want to do it dynamically through command line, you can write this in your yml file:
command: -c "jupyter lab --NotebookApp.tornado_settings='{\"headers\":{\"Content-Security-Policy\":\"frame-ancestors self *YourDomain.com*; report-uri /api/security/csp-report\"}}'"
