* run the ./build after setting the NIX_PATH. Previously the images were always generate with the system channel. Oops! * pin the outer shell version to nixos-19.09. skopeo broke in unstable. also we don't need to force the system here, technically this could run on macOS. |

docker-nixpkgs: docker images from nixpkgs
This project is a collection of docker images automatically produced with Nix and the latest nixpkgs package set. All the images are refreshed daily with the latest versions of nixpkgs.
It's also a good demonstration on how to build and publish Docker images with Nix.
Always keep your docker images fresh!
Why use Nix to build docker images?
Nix has a number of advantages over Dockerfile when producing docker images:
- builds are more likely to be repeatable and binary reproducible
- Nix will only rebuild the minimum set of changes with no manual intervention
- Nix produces optimised layers with no manual intervention
- nixpkgs provides automatic security updates
Example usage
Here is an example of using one of the docker images. Usage will change from image to image.
# run the curl image which has curl as an entry-point
$ docker run -ti --rm nixpkgs/curl curl http://ifconfig.co

Adding new images
To add a new image to the project, create a new folder under
./images/<image-name> with a default.nix that returns the docker image.
Then run nix-build -A <image-name> to test that it builds, and
then use
docker load -i /nix/store/...<image-name>.tar.gz to load and test the image.
