Creating new Nix derivations can feel daunting, but simple ones are actually pretty easy! Here we walk through packaging a simple Rubygem in Shopify's nixpkgs overlay.

Hey Burke,
Thanks for your nix tutorial series.
I would like to practice step by step as you do in this video.
But I haven't access to the Dev repo of Shopify.
Isn't better to create a video with public repos?

How can we create docker images in nix, I followed tutorial somewhere it built redis image but when I ran it couldn't run redis-cli inside container or was unable to run.

I now can install redis( nix-env -i nixpkgs.redis), but I do not know how to configure and manage it. for centos, if i install redis service, i can use systemctl to manage it, how can i manage it in nix?
