RancherOS cluster on vShpere

I’m trying to create a new k8s cluster on VSphere ESXi and there’s something I don’t understand.

I want to use Rancher OS instead of boot2docker. If I do it in Rancher 2.0, as I understand, it’ll only run the OS in RAM and everything will stay there. As I understand, running ros install would be the best practice, so that the OS is installed on disk.

Is it possible to do it from Rancher 2 ? Is it the way to go or you’re just running it in RAM ?

Thanks

Any inputs on this ?

Should I just run my OS in RAM ? Also if I do it, I won’t have a supported docker version ?

What image are you running and how did you set it up ?

Thanks
