[Nix-dev] 1000 EUR for a week of work with Nix and NixOps

[zimbatm]

Hi Seroka,

I would like to recommend terraform for the orchestration layer and then
use a pull model to deploy nix channels to your servers.

nixops is fantastic and I use it to deploy to my two servers but I don't
think it's the best solution to manage a constantly-changing fleet of
servers. When deploying a bigger infrastructure you want things like:
support for auto-scaling and shared deploy state between machines. Also
terraform has a much richer community and supports more cloud providers out
of the box.

The approach would be to start the machines either trough nixops or trough
provider-specific tools like Amazon's ASG and provision the
configuration.nix file during boot and finally run `nixos-rebuild switch
--upgrade`. The configuration would be setup to pull from one of your
private hydra channels. You can also use terraform to ssh into all of the
boxes if you want to control the rate of deploys.

Let me know if you want more details. It's pretty clear in my head but
didn't have the chance to implement this yet. I think Rok Garbas did
something similar for his personal setup if you want to talk to him.

Best,
z
