Matthew Garrett, a Google security engineer and well-known open-source developer, tweeted that while he thinks " Linuxkit is really interesting from a technical perspective," he also believes "Docker going to find the same thing everyone else does - companies with RHEL contracts hate running niche Linux distributions.
Is there a market for LinuxKit? Good question. We'll continue to invest in Alpine." McCauley also said LinuxKit is "a Linux subsystem focused on security." A stronger Alpine is a stronger LinuxKit. In a tweet, Nathan McCauley, Docker's security director, made it explicit that " Linuxkit's roots are in Alpine. The key difference is that LinuxKit is meant to be even more flexible and easier to customize. Alpine is, and will remain, Docker's native Linux for containers. As you'd expect, "All system services are containers, which means that everything can be removed or replaced." It's highly portable and can work on desktops, servers, IoT, mainframes, bare metal, and virtualized systems. At its smallest, LinuxKit Linux takes up only 35MB with an extremely fast boot time to match. The base LinuxKit Linux distribution is tiny. That way users who want Linux container support on platforms without native Linux such as macOS and Windows can run on these operating systems. LinuxKit enables this by bundling Linux into the Docker platform. It is a kit, very much in the Docker philosophy of batteries included but swappable." All components can be substituted with ones that match specific needs. All system services are containers that can be replaced, and everything that is not required can be removed. In a blog post, Justin Cormack, a Docker engineer, added: " LinuxKit includes the tooling to allow building custom Linux subsystems that only include exactly the components the runtime platform requires. As a result, systems created with LinuxKit have a smaller attack surface than general purpose systems." That's all true, but it's true of any containerized operating system. All of the processes, including system daemons, run in containers, enabling users to assemble a Linux subsystem with only the needed services.
