Requirements

Requirements to do Remote Deployment using NixOS native Tools.

NixOS System (Dev System)

  1. SSH-Access to Target-Host with Sudo Privileges.
  2. Don't forget to Configure your ssh Config! (See Hosts)
  3. This Configuration git clone https://git.kb-one.de/Serverraum-mit-Matratze/infra

Non NixOS System with Nix Package Manager (Dev System)

  1. SSH-Access to Target-Host with Sudo Privileges.
  2. Don't forget to Configure your ssh Config! (See Hosts)
  3. This Configuration git clone https://git.kb-one.de/Serverraum-mit-Matratze/infra
  4. Open Nix-Shell with nixos-rebuild Command available nix-shell -p '(nixos{}).nixos-rebuild'

Remote Deployment

So, you changed the Configuration on your Computer, how can you deploy it to the Server?

Warning

Don't forget to stage Added or Deleted Files! git add . (They will be ignored if you miss this step!)

Now Rebuild the System (on the Server) and Deploy it Remotely to the Server (Example mow0m):

nixos-rebuild switch --flake .#mow0m --build-host master@mow0m --target-host master@mow0m --use-remote-sudo
View command explanation (click to expand)

nixos-rebuild switch will rebuild a NixOS Configuration and Switch to it immediately, by restarting affected Services.

--flake . specifies the Directory of flake.nix with the NixOS System Configuration.

#mow0m tells it to Build the NixOS-System with the Hostname mow0m of the Flake. (See Hosts)

--build-host master@mow0m specifies the SSH-Connection to the Build-Host. We will build on the Target Host, to avoid messing with Signatures of the Nix-Store.

--target-host master@mow0m specifies the SSH-Connection to the Target-Host to deploy the Configuration to.

--use-remote-sudo this will redirect the Sudo-Prompt on the Target-Host to your Command-Prompt.
