K3S + iSCSI - 02 - How to Flash a Raspberry Pi to Boot from the Network

In this series, we go over how to install k3s (Light Kubernetes) on network booting Raspberry Pis to create a cluster. But unlike my previous release, this time we are using iSCSI to hold the linux filesystems. This makes it much better since it reduces issues caused by NFS.
In this second video, we prepare the Raspberry Pi to boot from the network by updating the bootloader with that capability. Finally, we prepare the SD Card to boot and copy all the necessary files to the NAS.

Hi, nice video ! What OS is on your custom image ? Is this Raspberry Pi OS or something else ? I would like to do the same thing with a Linux distribution like Debian or Fedora.

I am using Raspbian OS in my cluster but there are other Linux variants available for Raspberry Pis like Ubuntu, Debian, etc.
