Nix2container: faster container image rebuilds
2022-10-21 , Main track (Gym)

Nix2container is an alternative implementation to our
nixpkgs.dockerTools. Its main difference is to rely on Skopeo to
actually build the image: this allows us to use the container image
building logic of Skopeo and also provide opportunities to implement
more aggressive layer caching and skipping.


In this presentation, we first take a look at our current nixpkgs.dockerTools
functions and explain why they have been introduced. In the second
part, we will see how nix2container differs from dockerTools
functions: how it basically works and what are its unique features.
