History

I installed nix on windows 10 (WSL) following

https://nathan.gs/2019/04/12/nix-on-windows/

Exept that nix-shell did not work as expected (see: https://www.tweag.io/posts/2017-11-10-nix-on-wsl.html)

So I decided to run it inside a Docker, starting from: https://github.com/LnL7/nix-docker

First Hello, World

While looking for nix tutorials one seemed to me very well done: https://www.sam.today/blog/environments-with-nix-shell-learning-nix-pt-1/

This is the "test.nix" used in the first part of the Sam tutorial

# This imports the nix package collection,
# so we can access the `pkgs` and `stdenv` variables
with import <nixpkgs> {};

# Make a new "derivation" that represents our shell
stdenv.mkDerivation {
  name = "my-environment";

  # The packages in the `buildInputs` list will be added to the PATH in our shell
  buildInputs = [
    # cowsay is an arbitary package
    # see https://nixos.org/nixos/packages.html to search for more
    pkgs.cowsay
  ];
}

To try it "inside" a docker container it is possible to use a Dockerfile

FROM lnl7/nix:2.2
RUN mkdir -p /home/nix
COPY test.nix /home/nix
WORKDIR /home/nix
ENTRYPOINT nix-shell test.nix

Starting from this Dockerfile it is possible to create a docker image

docker build -t nix/test-shell-copy_entry .

After the build we can run the creted docker container with:

 docker run -it nix/test-shell-copy_entry
