Purpose: Builds container images with Nix without writing tarballs to the Nix store.
Layer reuse: Can skip already pushed layers without rebuilding them.
Image formats: The image configuration follows the OCI image specification.
Image loading: Examples show loading images into Docker and Podman.
Base images: Can pull base images from a container registry by digest or from a supplied manifest file.
Layer caching: Dedicated layers can isolate dependencies so unchanged layers need not be rebuilt or pushed.
Permissions: File permissions can be set when a tar layer is created without writing those permissions to the Nix store.
Registry authentication: The documentation describes configuring registry authentication for Nix daemon builds using Docker credentials and a Skopeo auth file.
Architecture: The getting-started example selects the x86_64-linux system.
Security setting: Image-pull functions default tlsVerify to true.
License: The repository includes the Apache License, Version 2.0.
Support: Commercial support is available for customizations, image optimizations, best-practices guidance, and bug fixes by contacting the maintainer.
Testing limitation: The project documentation says its container tests do not run in the Nix sandbox because running a container there is currently not possible.
