Create a VM template from the latest Debian release with settings appropriate for the CCCHH Proxmox clusters

Prerequisites

The script uses the package libguestfs-tools' virt-builder to download and customize a Debian image. and then add it as a template to Proxmox.

Building the Template

Configuration Options

Verify that the settings at the beginning of the script are suitable to the cluster you want to create the template from.

Variable	Default	Description
VMID	9023	ID the template should have in Proxmox
STORAGE	local-zfs	Pool the disks should be created in
OS	debian-12	virt-builder name of the OS to install
NAME	chaos-${OS}-tmpl	name of the template
BRIDGE	vmbr0,tag=208	name of the bridge to use and any parameters needed, like the VLAN tag

authorized_keys

The script expects authorized_keys to be in the current directory. Copy the correct contents from the appropriate repository.

Run the Script

./build-proxmox-template

Cloning the Template

Please use "Full Clone" when creating a VM based on this template. Using Linked Clone means that the template's disk cannot be recreated since the linked clones need it. This means that the script cannot update the template.
