 The most Docker-native approach is to fetch a container from the Docker registry and to illustrate that we're going to begin from the previous chapter's example integration test:

 This creates a new `postgrest` container that doesn't depend on the Docker registry at all.  Note that the Docker registry *does host* an official `postgrest` image but we're not going to use that image.  Instead, we're using a `postgrest` Docker image built entirely using Nix.

 The easiest way to illustrate how NixOS containers work is to redo our `postgrest` example to put both Postgres and PostgREST in separate NixOS containers.  We're going to begin by resetting our example back to the non-container example from the previous chapter:

 garnix requires the use of Nix flakes in order to support [efficient evaluation caching](https://www.tweag.io/blog/2020-06-25-eval-cache/) and the good news is that we can already build our NixOS system without any changes to our flake, but it might not be obvious how at first glance.

 In fact, we don't even need to create a local copy of the `cowsay` template flake.  We could also have run the flake directly from the GitHub repository where it's hosted:

 This works because flakes support GitHub URIs, so all of the flake operations in this chapter work directly on the GitHub repository without having to clone or template the repository locally.  However, for simplicity all of the following examples will still assume you templated the flake locally.
