Voila over HTTPS/TLS

[christandlg]

I'm running Voila to serve notebooks created with JupyterHub. I tried to pass ssl_options to Tornado by running Voila with the arguments --Voila.tornado_settings='{"headers":{"Content-Security-Policy":"frame-ancestors *:*;" }, "ssl_options":{"certfile":"/etc/ssl/certs/my.pem", "keyfile":"/etc/ssl/private/my.key"}}' but Voila is still served over HTTP only (browsing to http://myhost:8866 works but is not encrypted, browsing to https://myhost:8866 just times out). Both the certificate and key file are readable by the user that runs voila.
I am not using Jupyter Notebook, so I'm afraid the solution in #508 does not work for me.

If this is not possible yet, I'd like to request this as a feature.

I was able to get Voila serve over https by editing ...\lib\site-packages\voila\app.py

-- replace:
self.app.listen(port)
-- with:
self.app.listen(port, ssl_options={'certfile':'path-to-cert\cert.pem', 'keyfile':'path-to-key\key.pem'} )

-- and replace:
proto = 'http'
-- with:
proto = 'https'

I am using voila version 0.2.3 as standalone application.

It might have been mentioned in another issue, but this might be addressed in a more streamlined and easier manner when Voila switches to using the Jupyter Server ExtensionApp: #592

@abalbekov that actually worked! The only problem I got is that Chrome does not trust the certificate issued by letsencrypt
