> I feel Docker is a better solution to application deployment than Nix is.

So use Nix to build your Docker images (or rather OCI images).

That's the same thing I do and it is great.

I don't need much on my host server side but having that stuff be easily configurable in one place and be mostly idempotent made my life easier.

I'm somewhat out of my depth here, but isn't Vagrant suitable for this purpose?

No no no. Vagrant is for spinning up dev environment VMs with a virtualization tool like VirtualBox.

You usually use Vagrant to provision a machine with a suitable image and then use some other tech to setup your environment on that image. Common choices are Chef, Puppet or Salt, last time I checked.

You can use NixOS to replace both the OS image and the configuration tech.

You don't use Vagrant for your desktop, do you?

Great run-through, thank you!
