|
# Usage:
|
|
# ./make-debian-cloudinit-template.sh <VMID> [CODENAME]
|
|
#
|

|
|
# STORAGE Proxmox storage pool for disks (default: local-zfs)
|
|
# BRIDGE Network bridge (default: vmbr0)
|
|
# MEMORY RAM in MB (default: 2048)

|
# CORES CPU cores (default: 4)
|
|
# NAME Template name in Proxmox (default: debian-<CODENAME>-cloudinit-<VMID>)
