There are three ways at the time to install NixOS on Hetzner

# From Hetzner's rescue image one can boot into the nixos installer using a custom kexec image that is configured with the fixed ~~IP provied~~ by Hetzner and also contain your ssh key. Tip: The kexec tarball as generated by nixos-generators can remain put into the /boot partition for future use.

# From Hetzner's rescue image one can boot into the nixos installer using a custom kexec image that is configured with the fixed IPv6 provided by Hetzner and also contain your ssh key. Tip: The kexec tarball as generated by nixos-generators can remain put into the /boot partition for future use.

# Hetzner also provides an interface to upload your own ISO-images. Also here you may want to build your own iso-image, which has openssh with ssh keys due the lack of a remote console.

# An easier method to install NixOS on Hetzner, is to use the existing integration into NixOps.

From Hetzner's [https://accounts.hetzner.com/login web interface], one can obtain both ipv4/ipv6 addresses and gateways.

Hetzner does ~~not operate dhcp~~ servers, so you need to assign those statically.

Hetzner does announce ipv6 addresses servers, so you need to assign those statically.

In this example we use networkd to configure the interface. The same configuration can be used for both

the kexec image and the final server.

the kexec installation image and the final server configuration.
