We'll contrast Nix with other ecosystems like Debian and Alpine and highlight some of the unique properties that make Container images with Nix Nix was explicitly designed to capture all dependencies of a software component. Nix lets you pick and choose the software that is visible in Building slim docker containers is a breeze without needing to manually handle multiple layers to copy build artifacts from. We compare the two approaches and show how they can complement each other. I always heard that with Nix you can build quite the minimal docker images and make . nix that works perfectly - I can run nix-shell locally and get everything I need. I personally find it very interesting, especially since the “normal” way of building Docker images rely on Docker image with non-root Nix If you would like to run Nix in a container under a user other than root, you can build an image with a non-root single-user installation of Nix by specifying Discussion on why Nix is considered a superior alternative to Docker's image builder in the programming community.
