Prerequisites to install Nuvolaris in a Linux server

You can install Nuvolaris on any server either in your intranet or on in Internet running a Linux distribution, with the following requirements:

You know the IP address or DNS name of the server on Internet or in your Intranet.
The server requires at least 8GB of memory and 30GB of disk space available.
It should be running a Linux distribution supported by K3S.
You must open the firewall to access ports 80, 443 and 6443 (for K3S) or 16443 (for MicroK8S) from your machine.
You have to install a public ssh key to access it without a password.
You have to configure sudo to execute root commands without a password.

You can:

get a server on any cloud provider or even install by yourself and then configure it
provision such a server with nuv on Amazon Web Services
provision such a server with nuv on on Google Cloud Platform

Once you have such a server you can optionally (it is not required) install K3S or MicroK8S in it.

Once you have configured you server, you can proceed configuring Nuvolaris for the installation.
