Nix not only provides the packages to include in the images, but also builds the images themselves by using a special layering strategy that optimises for cache efficiency.
For general information on why using Nix makes sense for container images, check out this blog post.
Simply pull an image from this registry, separating each package you want included by a slash:
docker pull nixery.dev/shell/git/htop
This gives you an image with
htop and an interactively configured
shell. You could run it like this:
docker run -ti nixery.dev/shell/git/htop bash
Each path segment corresponds either to a key in the Nix package set, or a meta-package that automatically expands to several other packages.
Meta-packages must be the first path component if they are used. Currently
the only meta-package is
shell, which provides a
bash-shell with interactive
configuration and standard tools like
Tip: When pulling from a private Nixery instance, replace
the above examples with your registry address.

The instance at
nixery.dev tracks a recent NixOS channel, currently NixOS
20.09. The channel is updated several times a day.
Private registries might be configured to track a different channel (such as
nixos-unstable) or even track a git repository with custom packages.
While we appreciate the enthusiasm, if you would like to use Nixery in your
production project we recommend setting up a private instance. The public Nixery
nixery.dev is run on a best-effort basis and we make no guarantees about
