docker-nixpkgs: docker images from nixpkgs

This project is a collection of docker images automatically produced with Nix and the latest nixpkgs package set. It even refreshes every morning a 4:00 UTC thanks to the Gitlab CI schedules.

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 actually reproducible
• Nix will only rebuild the minimum set of changes
• Nix can produce automatic optimised layers for you
• 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.

# the user must have an account at gitlab
$ docker login registry.gitlab.com
# run the curl image which has curl as an entry-point
$ docker run -ti --rm registry.gitlab.com/zimbatm/docker-nixpkgs/curl http://ifconfig.co
