Dependencies

To remotely Deploy Nix-Servers with Native Tools, you will need Access to the nixos-rebuild command.

You can either use a NixOS System.

Or you can Install the Nix Package Manager and open a Nix-Shell with the Command available:

nix-shell -p '(nixos{}).nixos-rebuild'

Updating Configuration

So, you updated the Configuration on your Computer, how can you apply the Updated Config to the Server?

You'll need SSH-Access to the Server, with a User which can run Nix-Commands, and can escalate Privileges using sudo.

1. Don't forget to Configure your ssh Config! (See Hosts)
2. Stage the Changes if you created or deleted Files git add . (They will be ignored if you miss this step!)
3. Build and Switch the Config on the Target Server! (Example mow0m):

nixos-rebuild switch --flake .#mow0m --target-host master@mow0m --build-host master@mow0m --use-remote-sudo 

You want to keep the Build-Host the Same as the Target-Host, because the Target will only accept Binarys with a trusted Signature. It is way easier, to just run the Build on the Same Machine then.
