Booting devices from the net by PXE is a good way to start diskless devices or provisioning new devices. A new tool is presented iVentoy. Or do it the traditional way with DNSMASQ or DHCP by TFTP. #pxe #iventou #netboot #proxydhcp

Oops!
This happens some times especially on older consumer grade stuff like SATA disks but also enterprise grade stuff will break. Newer ever think you don't need backup's, you do! ZFS makes all this easier.
Tools
Some scripts I use to set up and destroy clusters or just build a set ot VM's. I use the cloud-images for a ready-to-run VM with minimal intervention. #proxmox #automation #script

How to automate creation of templates and VM's in Proxmox. This script builds templates to be the base for VM's in k8s or anything else in your cluster. You can easily choose from the menu what to do like auto install qemu-guest-agent. Or by editing and commenting or de-commenting lines.
