MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms. As such, MirageOS is a collection of libraries and tools, as well as a development workflow. This means that any given release is a set of related libraries, intended for use by application developers, with various dependencies and independent version numbers.
All MirageOS libraries are released via the OCaml Package Manager (OPAM), which makes it easy for developers to obtain the libraries, with OPAM managing the dependencies. To being using MirageOS, you must first install OPAM. Once OPAM is installed, obtaining the latest release of MirageOS is as simple as opam install mirage.
Although we do not recommend using outdated package sets, below are links on how to obtain previous versions. These outdated versions of the MirageOS packages set are unsupported and we encourage all users to remain up to date. Keeping your package set up to date is as easy as opam update, followed by opam upgrade. We recommend you do this on a regular basis to benefit from frequent bug fixes and new features.
