Question

Is it possible to install Vantage OnPrem at the machine which is not connected to internet?

Is the internet connection required for Vantage On-Premise installation?

Answer

In Vantage 2.1.2 version, installation procedure strongly requires internet connection because necessary data is downloaded from public docker registry on web.

Starting from Vantage 2.1.3 and later, the internet connection is not required for the  installation. The installation procedure allows using private docker registry for the installation. Still, the the docker images should be first downloaded from the internet.
