Add view-only switch to vnc configuration

[xlemmingx]

Description of the problem: By default the vnc session allows interactions including moving/closing the browser and accessing the underlying container. To avoid confusion and minimize security risks, a switch or configuration property to only allow view mode on server side would be great. The client switch in novnc is not a proper alternative.

Browser and version: All Browsers affected

Operating system: Debian 10 64 bit

WebDriverManager version: WDM 5.0.1

WebDriverManager call: WebDriverManager.getInstance(String.valueOf(type)).browserInDocker().enableVnc().dockerScreenResolution("1920x1080x24").create();

Thanks for your great work, loving v5 and the docker features so far!

At this moment, to achieve that, you simply need to set to true the URL parameter view_only to your noVNC URL. For instance:

http://localhost:49161/?view_only=true

Yes but every user can remove that URL parameter and therefore get full access again. That's why I'm looking for a server sided solution as mentioned here (via environment variable): https://github.com/SeleniumHQ/docker-selenium

If you want to run VNC in view-only mode you can set the environment variable VNC_VIEW_ONLY=1.

But I think I currently don't have the possibility to add environment variables to the browser containers since WDM is starting them for me. Or did I miss something?

I added an API method to configure this in version 5.0.3, just released. See doc.
