your server is now fully defined in configuration.nix

Is this really true?

I mean, most software comes with its own config file, which has to be maintained too.

Yes, I'll make a followup blog post on this, but basically all your other config files are generated from configuration.nix as well. They try to have sane defaults, so that's why the default configuration file is so small. Near the bottom of the blog post I define systemd units. Those are turned into SystemD configuration files which are put in the right location so systemd sees them, NixOS does that for everything. For example my IRC client (irssi) is configured using a Nix configuration file as well.

other config files are generated from configuration.nix

Ah, now I get it.

So if I have to use stuff like Zsh or Atom, the only reason they have their own configs is, that no one bothered to write a Nix expression to generate them with their packages?

I'm not totally sure of the point of using docker in this example. I don't really get what docker can do that can't be done better with pure nixos (and a simpler container system if you're in it for the supposed security benefits of docker)

Docker abstracts the operating system from the application layer, that's the only reason why I'm using Docker. I don't see the advantage of using NixOS to install my applications. With Docker your application is just fetched as a static binary blob as defined by your developers, so no worries :)

Not the way I like doing it as it is entirely inflexible from a deployment point of view.
