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
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 188.8.131.52
Each image is built with the following nixpkgs channels and map to the following image tag.
The version of the packages included in each image depends on what version the nixpkgs channel describes.
|nixos-23.05||nixos-23.05||only minor versions that include security updates|
|nixos-23.11||nixos-23.11||only minor versions that include security updates|
|nixos-unstable||latest||latest and greatest, major versions might change|

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.
nix-build -A <image-name> to test that it builds, and
docker load -i /nix/store/...<image-name>.tar.gz to load and test the image.
If you have any problems with or questions about this project, please contact us through a GitHub issue
Submit a request with an accompanying use-case for an image that you would like to see.
You are invited to contribute new features, fixes or updates, large or small; we are always thrilled to receive pull requests, and do our best to process them as fast as we can.
The docker-library is an image set maintained by the Docker Inc. team and contain officially-supported images.
Nixery is a pretty cool service that builds docker images from nixpkgs attributes on the fly.
