Voila.ip option not in documentation and -h help string

[tomanizer]

Follow up from #443

Viola has an option to serve the dashboard on a public interface using the voila.ip parameter.
However this is not mentioned in the documentation which only refers to serving on localhost,
It is also not referenced in the voila help string -h..
-h only refers to the port, but not the IP address.

The option should be added to the documentation and the help string.

Btw it is spelled voila ;)

Thanks @tomanizer for opening a new issue to keep track of this.

Would you like to open a PR to add it to the documentation?

[tomanizer]

Yes. Let me try to add this.

It could also be good to expose --Voila.ip as --ip as in JupyterLab.

It could also be good to expose --Voila.ip as --ip as in JupyterLab.

This should come "for free" with #492.

In the meantime we could add an alias here:

voila/voila/app.py

Lines 119 to 129 in e97044f

	aliases = {
	'port': 'Voila.port',
	'static': 'Voila.static_root',
	'strip_sources': 'VoilaConfiguration.strip_sources',
	'autoreload': 'Voila.autoreload',
	'template': 'VoilaConfiguration.template',
	'theme': 'VoilaConfiguration.theme',
	'base_url': 'Voila.base_url',
	'server_url': 'Voila.server_url',
	'enable_nbextensions': 'VoilaConfiguration.enable_nbextensions'
	}

Just came here to say that this is related to the recent bugfix in 0.3.0 which changes the default behaviour and this option is missing to change it back to the old behaviour.

Edit: I needed to set this option in order for the docker deployment to work
