NixOS configuration for shared remote development via SSH

Getting started

Terminology:

• Host: The machine you are installing NixOS on.
  • It must already be running Linux (which could even be booted off a rescue image)
• Guest: Your current machine, from which you are remotely doing the install.

Step	Host	Guest
1.	Add your SSH key to authorized_keys file in /root/.ssh	Add the same key in your configuration (here, flake.nix) under: users.users.root.openssh.authorizedKeys.keys = [ "<your-ssh-key>" ];
2.	Run lsblk to find the <device-name> of the disk to partition. For example, nvme0n1 is the device here: ❯ lsblk NAME MAJ:MIN RM SIZE RO TYPE nvme0n1 259:0 0 1.9T 0 disk
3.		In disk-config.nix, set disko.devices.disk.main.device = "/dev/<device-name>";
4.		nix run github:nix-community/nixos-anywhere -- --flake .#office root@<ip-address>
5.		Deploy incremental changes with nix run github:serokell/deploy-rs -- --remote-build .#nixos-remote-01

Disclaimer: The <ip-address>¹ might change in kexec mode or post-installation, in which case SSH connection will timeout, the solution is to Ctrl-C and rerun Step 4 with updated <ip-address>.

Footnotes

1. Find the <ip-address> using ifconfig or ip a. Under the device name you will find a line that looks like: inet <ip-address> ... ↩
