NixOS-Infect

What is this?

A script to install NixOS on non-NixOS hosts.

NixOS-Infect is so named because of the high likelihood of rendering a system inoperable. Use with extreme caution and preferably only on newly provisioned systems.

This script has successfully been tested on at least the follow hosting providers and plans:

Should you find that it works on your hoster, feel free to update this README and issue a pull request.

Motivation

Motivation for this script: nixos-assimilate should supplant this script entirely, if it's ever completed. nixos-in-place was quite broken when I tried it, and also took a pretty janky approach that was substantially more complex than this (although it supported more platforms): it didn't install to root (/nixos instead), left dregs of the old filesystem (almost always unnecessary since starting from a fresh deployment), and most importantly, simply didn't work for me! (old system was being because grub wasnt properly reinstalled)

How do I use it?

Read and understand the the script
Deploy any custom configuration you want on your host
Deploy your host as non-Nix Operating System.
Deploy an SSH key for the root user.

NB: This step is important. The root user will not have a password when nixos-infect runs to completion. To enable root login, you must have an SSH key configured.

run the script with:

  curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | NIX_CHANNEL=nixos-23.05 bash -x

NB: This script wipes out the targeted host's root filesystem when it runs to completion. Any errors halt execution. A failure will leave the system in an inconsistent state, and so it is advised to run with bash -x.

Hoster notes:

Digital Ocean

You may utilize Digital Ocean's "user data" mechanism (found in the Web UI or HTTP API), and supply to it the following example yaml stanzas:

#cloud-config

runcmd:
  - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | PROVIDER=digitalocean NIX_CHANNEL=nixos-23.05 bash 2>&1 | tee /tmp/infect.log

Potential tweaks:

/etc/nixos/{,hardware-}configuration.nix: rudimentary mostly static config
/etc/nixos/networking.nix: networking settings determined at runtime tweak if no ipv6, different number of adapters, etc.

#cloud-config
write_files:
- path: /etc/nixos/host.nix
  permissions: '0644'
  content: |
    {pkgs, ...}:
    {
      environment.systemPackages = with pkgs; [ vim ];
    }    
runcmd:
  - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | PROVIDER=digitalocean NIXOS_IMPORT=./host.nix NIX_CHANNEL=nixos-23.05 bash 2>&1 | tee /tmp/infect.log

Vultr

To set up a NixOS Vultr server, instantiate an Ubuntu box with the following "Cloud-Init User-Data":

#!/bin/sh

curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | NIX_CHANNEL=nixos-23.05 bash

Allow for a few minutes over the usual Ubuntu deployment time for NixOS to download & install itself.

OVHcloud

Before executing the install script, you may need to check your mounts with df -h. By default, OVH adds a relatively short in memory tmpfs mount on the /tmp folder, so the install script runs short in memory and fails. Just execute umount /tmp before launching the install script.

Contabo

Tested on Cloud VPS. Contabo sets the hostname to something like vmi######.contaboserver.net, Nixos only allows RFC 1035 compliant hostnames (see here). Run hostname something_without_dots before running the script. If you run the script before changing the hostname - remove the /etc/nixos/configuration.nix so it's regenerated with the new hostname.

AWS Lightsail

Make sure to set PROVIDER="lightsail".

Setting a root ssh key manually is not necessary, the key provided as part of the instance launch process will be used.

If you run into issues, debug using the most similar ec2 instance that is on the Nitro platform. Nitro platform instances have a serial console that allow you to troubleshoot boot issues, and Lightsail instances are just EC2 with a different pricing model and UI.

Windcloud

Scaleway

As of November 2020, it is easy to get a NixOS VM running on Scaleway by using nixos-infect and Scaleway's support for cloud init. All that is needed is to follow the nixos-infect recipe for Digital Ocean, removing the Digital Ocean-specific stuff. So, pragmatically, start an Ubuntu or Fedora VM and use something like the following as your cloud-init startup script:

#cloud-config
write_files:
- path: /etc/nixos/host.nix
  permissions: '0644'
  content: |
    {pkgs, ...}:
    {
      environment.systemPackages = with pkgs; [ tmux ];
    }
runcmd:
  - curl https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect |  NIXOS_IMPORT=./host.nix NIX_CHANNEL=nixos-23.05 bash 2>&1 | tee /tmp/infect.log

RackNerd

Remember that the SSH keys are not automatically generated/uploaded, so you need to create them as usual with ssh-keygen or some other means, add the public key to the .ssh/authorized_keys file on the remote host, and have a copy of the private key on your local box.

On RackNerd's Ubuntu 20.04, there's no curl by default, so wget -O- needs to be used instead:

# wget -O- https://raw.githubusercontent.com/elitak/nixos-infect/master/nixos-infect | NIX_CHANNEL=nixos-23.05 bash -x
