## VM Preparation
The VM template needs a few cloud-init tools installed before we can use it with cloud-init configs
### Debian
[shroot]
```sh
apt install cloud-init cloud-initramfs-growroot
```
[/shroot]
## Cloud-init
Cloud-init has a config file in `/etc/cloud/cloud.cfg`
### Growing partitions
With growroot installed in the initramfs, cloud-init will expand partitions and filesystems to fit the root partition given.
### XCP-ng: Set Hostname
This cloud config snippet sets the machine hostname to the VM name.
```
#cloud-config
hostname: {name}
```
## Network config
The network config is a special config file with cloud-init that focuses on specifying network settings.
### Set Static IP
The snippet below sets a static ip address for the specified interface.
Its syntax mainly follows the `/etc/network/interfaces` syntax.
```
network:
version: 1
config:
- type: physical
name: [INTERFACE]
subnets:
- type: static
address: [ADDRESS]
gateway: [ADDRESS]
dns_nameservers: [ADDRESS]
```
