How MirageOS Powers Docker Desktop

Recently, I posted about how vpnkit, built with MirageOS libraries, powers Docker Desktop. Docker Desktop enables users to build, share and run isolated, containerised applications on either a Mac or Windows environment. With millions of users, it's the most popular developer tool on the planet. Hence, MirageOS networking libraries transparently handle the traffic of millions of containers, simplifying many developers' experience every day.
