Remote deployment with NixOS
You can set up an agent on a remote NixOS machine by following the same NixOS instructions via an SSH connection.
Instead of deploying with Terraform, or NixOps with
deployment.targetEnv = "none", you could script the deployment yourself.
nixos-rebuild has a
--target-host option to make deployment via SSH easier. Evaluation of the NixOS configuration will happen on your local machine, but build and activation are performed via SSH.
[user@workstation:~/my-agent]$ NIXOS_CONFIG=$PWD/configuration.nix nixos-rebuild --target-host my-agent
Note that this determines the NixOS version via
NIX_PATH, which defaults to a channel on
Updating the secret files is still a manual operation.
