Hi everyone!

I saw that NixOS is getting popularity recently. I really have no idea why and how this OS works. Can you guys help me understanding all of this ?

Thanks !

    Great points and perspective!

    I think NixOS at this point is great to know and have an eye on for new projects that happen to require some preconfigured OS “underneath”. I wouldn’t think about migrate existing, working infrastructure into NixOS either, ‘just because’.

      It occurred to me that NixOS might have a hard time doing something like this:

      • create a 6 node Docker Swarm cluster, where 3 of the nodes are managers

      I can see NixOS doing a fine job of templating a standard build that includes the Docker engine. But working out which one gets to init the swarm, which ones get to join as managers, which ones get to join as workers? Yeah, that’s probably better off left to something like Ansible.

        You must’ve misunderstood. This sort of thing is exactly what NixOS excels at!

        In the Nixpkgs CI, we often spin up multiple VMs in a single test to ensure things like networking between machines work as expected, all using relatively straight forward NixOS primitives.

        I do not believe Docker Swarm specifically is supported (it’s a proprietary platform, so community interest understandably isn’t very high) but near same configurations with small differences are trivial to do with NixOS modules and they are a generic mechanism (can even be used to i.e. configure Android images and many other things).

        I can see NixOS doing a fine job of templating a standard build that includes the Docker engine.

        Note that NixOS’ module system is far far more powerful than simple templating.
