Proxmox Cloud-Init Template Service

A terminal-based utility that helps you build cloud-init–ready Linux VM templates in Proxmox VE, so you can stop clicking through the web UI and start templating like a boss.

It simplifies the creation of cloud-init–enabled VM templates using official Linux cloud images. The script presents a menu-driven interface (via whiptail) to select from a list of popular distributions (e.g., Ubuntu, Debian, CentOS, Fedora, Gentoo, openSUSE), and automatically downloads, imports, and configures them as reusable Proxmox templates.

FEATURES

• Supports official qcow2 cloud images (NoCloud or GenericCloud)
• Imports as VMs, sets required flags, enables serial console
• Converts VMs into reusable cloud-init templates
• Uses whiptail as the user interface
• Designed for simplicity, speed, and Proxmox sanity
• Smart image selection tailored for Proxmox compatibility
• Downloads and caches the official distro image selected for future use (qcow2 format)
• Uses clearly tagged distro labels for broad terminal compatibility
