Default docker example doesn't work

[ctron]

Introduce your stance

I want to build a nix package using docker/podman.

Describe the issue

The documentation at https://nixos.org/download/#nix-install-docker says:

$ git clone --depth=1 https://github.com/NixOS/nixpkgs.git
$ docker run -it -v $(pwd)/nixpkgs:/nixpkgs nixos/nix
docker> nix-build -I nixpkgs=/nixpkgs -A hello
docker> find ./result # this symlink points to the build package

However, that results in:

bash-5.2# nix-build -I nixpkgs=/nixpkgs -A hello
error: path '/default.nix' does not exist

I have no idea how to resolve this.
