This is yet another deployment tool for NixOS. This tries to be as easy to use as possible while not introducing new concepts to NixOS.
This deployment tool looks to the future and thus it is mostly usable only if you use Flakes!
The concept is that Nix Flakes allow you to manage multiple NixOS profiles in a single repository. The only thing that is missing at that point is the deployment solution, that is definition where and how to build and copy and apply new NixOS version. This tries to deal with already existing systems where you have SSH access and configured way to get root access. The NixOS module in this repository specifies configuration for nixdeploy script.
NixDeploy consist of NixOS configuration module and nixdeploy tool itself.
The configuration can be bootstrapped with:
nix flake init -t gitlab:cynerd/nixosdeployThis will copy to your current work directory template from this repository that
is prepared to be used with NixDeploy. If you already have existing
configurations, then you can just add this repository as flake input and
nixosModules.default to modules your configurations import.
The important step is to activate deployment in your configuration. The simplest
is to just include option deploy.enable = true;.
The next step is to actually run nixdeploy. You have few options how to run
it, you can either run it directly from this flake with nix run gitlab:cynerd/nixdeploy or you can install it as package to your system, but
the preferred way is to make it a default package of you flake:
packages.x86_64-linux.default = nixosdeploy.packages.x86_64-linux.default;Now you can just do nix run . to invoke NixDeploy. The advantage of this is
that consistency between NixOS module and the tool is ensured.
Now you can read the help of the nixdeploy with nix run . -- -h.
All available configuration can be seen in NixOS module file in this repository.
