Robur Reproducible Builds

Published: 2021-11-16 (last updated: 2023-02-09)

In 2021 we in Robur have been working towards easing deployment of reproducible mirage applications. The work has been funded by the European Union under the Next Generation Internet (NGI Pointer) initiative. The result is online.

The overall goal is to push MirageOS into production in a trustworthy way. We worked on reproducible builds for Opam packages and MirageOS - with the infrastructure being reproducible itself. Reproducible builds are crucial for supply chain security - everyone can reproduce the exact same binary (by using the same sources and environment), without reproducible builds we would not publish binaries.

Reproducible builds are also great for fleet management: by inspecting the hash of the binary that is executed, we can figure out which versions of which libraries are in the unikernel - and suggest updates if newer builds are available or if a used library has a security flaw -- albatross-client-local update my-unikernel is everything needed for an update.

Several ready-to-use MirageOS unikernels are built on a daily basis - ranging from authoritative DNS servers (secondary, let's encrypt DNS solver), DNS-and-DHCP service (similar to dnsmasq), TLS reverse proxy, Unipi - a web server that delivers content from a git repository, DNS resolver, CalDAV server, and of course your own MirageOS unikernel.

It has been developed since 2009 at the University of Cambridge, UK and is written in the programming language <a href="/Our%20Work/Technology-Employed#OCaml">OCaml</a>.</p> <p>It compiles the necessary OCaml libraries into a unikernel - a small operating system, each built for a certain purpose. For each unikernel we can pick from hundreds of permissively licensed open source libraries which implement network protocols, storage on block devices, or interfaces to network devices via the hypervisor or host operating system. As we only put into each one exactly what is needed, each unikernel is fast; instantly booting and, as there is less code base, it is easier to maintain and keep secure.</p> <p>As an example to see how lines of code compare, here are the number of lines of code needed for different elements of our <a href="/Our%20Work/Projects#Bitcoin%20Pinata">Bitcoin Pinata</a>, measured in thousands of lines of code:</p>
