- Use the latest Nix version 1.11.14.
- Attempts to download the Nix installation tarball from http://nixos.org
redirect to https these days, which wget doesn't support unless OpenSSL is
available.
- Use addgroup and adduser commands to create the Nix build users.
- Link the Nix profile script into /etc/profile.d, where it's run
automatically.
- Dropped installation of bash and tar. Neither tool is essential for running
Nix.
Use the command "docker build -t nix . && docker run -it --rm nix sh -"
to build and run the Nix docker container.
