The following guide will result in a fully setup Proxmox environment on a Hetzner dedicated server with additional IPs and subnets imported from the Hetzner Robot API via script

What does this script do?

  • Install Proxmox on your server
  • Let’s Encrypt Certificate for the Proxmox-Interface
  • Option to use Thin-Pool Storage
  • Read the Server-IPs (Single-IP and Subnet) from the Hetzner-Robot
  • Write the Network-Config
  • Option to create private IPs if you use a vSwitch

Please note:

If you would like to use a Thin-Pool for Proxmox, run the below (make your customizations):

PART lvm pve all
LV   pve root / ext4 10G


Begin by installing the minimal Debian-Stretch or Debian-Buster using the Rescue option via the Robot interface in Hetzner.

Once installed, set a hostname or FQDN on your host machine – this can be done by editing two files:

nano /etc/hostname
nano /etc/hosts

After changing the hostname, restart your host.

Once rebooted, proceed to download the script as follows:

apt -y update
apt -y install php-cli php-curl wget
cd /root
tar xfz hetzner-proxmox.tgz
cd proxmox

Now to prepare the Proxmox Enviroment:

php install-proxmox.php

Upon running the script, it will check and verify your OS and also show the Proxmox version:

Detected OS: Debian Buster
Install Proxmox-Version: 6.x

The script will proceed to ask the following questions:

Full qualified hostname (FQDN) of the server [server]:

Make sure to use the full FQDN you set earlier (i.e otherwise Let’s Encrypt will not work!

IP of the server []:

The IP should be already populated by default, if not, then add your host IP.

Network Card [enp0s31f6]:

Your network card may be of a different name for example, eth0, eth1, etc.

Do you want to autoconfigure the network? (y,n) [y]:

To automatically import additional IPs and/or subnets, chose “Y” and continue to input your Hetzner Robot API credentials:

Enter your credentials for the Hetzner-API
robot_url []:
robot_user []: 
robot_password []:

Next, you will be asked if you would like to enable Thin-Pool:

Enabled Thin-Pool for Proxmox? (y,n) [n]:

If you have chosen to install a Thin-Pool, it will say the following:

Only one LV found - using pve
Use LV Name for Proxmox Thin-Pool - 'none' to skip [data]:

You will be asked to permit SSH and on what port, it is advised to keep this as default:

SSH Port [22]:
SSH PremitRootLogin [yes]:

Let’s Encrypt

Now an SSL certificate can be installed. Input your email for the script to continue and challenge ACME:

Email to use with Let's Encrypt and in scripts [[email protected]]:
Use Let's Encrypt for the Interface (y,n) [y]:


This step will initiate the Proxmox Install:

Start Proxmox Install? (y,n) [y]:

Once this finalizes, you will be able to access your Proxmox environment using or using your host IP with port 8006


If you use a vSwitch, proceed with the script:

This server is connected to the vswitch with the ID 4868 [4001]
Add the vswitch to the network-config? (y,n) [y]:
Use Private IP []:
Use Private IP []: 
Netmask [24]:

After setting your vSwitch, reboot your host, once restarted you can access your Proxmox environment again via https://yourdomain or using your host IP with port 8006.
