# 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`](https://libguestfs.org)' `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](https://gitlab.hamburg.ccc.de/ccchh/infrastructure-authorized-keys).
|
|
|
|
### Run the Script
|
|
|
|
```shell
|
|
./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. |
