So I have my machines PXE booting into RancherOS. My question is do I need to install RancherOS to the disk now using the cloud-config?

I want the OS to run in Ram but save the docker images, etc. to the hard disks.

Is it recommended to run the OS in a ramdisk ( since it’s only 30mb or so ). Or should all my machines PXE boot, install to the hard disk and reboot into the installed version of the OS?

Thanks,

Hi,

take a look at persisting state / RANCHER\_STATE  
[http://docs.rancher.com/os/running-rancheros/workstation/boot-from-iso/](http://docs.rancher.com/os/running-rancheros/workstation/boot-from-iso/)

It should work.

I did this and it still downloads the images to ram and doesn’t persist through reboots. Any ideas?
