Can i use Proxmox cloud-init with the DietpiI ISO in a VM?
@StephanStS is running quite some Proxmox systems as far as I know
@doko1975: What is the target of cloud-init?
If you install DietPi in a VM, it starts with an automatic first-time-install run which sets up the most things for you. No special user etc. need to be added for a first touch to the system.
BTW: You actually can easily use a DietPi .iso image and generate a DietPi VM like you are familiar with within Proxmox: Just generate a VM with its necessary ressources and let it boot from an ISO image (-> CD-ROM boot).
You can use this image: https://dietpi.com/downloads/images/DietPi_VM-x86_64-Bookworm_Installer.iso
This might be more familiar to you compared to the installation method we have actually described in our installation docs.
