At work we went back to a Docker build to make reproducible images. The primary reason is poor cross-compilation support in Nix on Arm when developers needed to compile for an amd64 service and derive image checksums that are put into tooling that are run locally for service version verification and reproducibility. With Docker it turned out relatively straightforward. With Nix even when it runs in Linux Arm VM we tried but just gave up.
