If we can build many, we can network them all together. If we can build one Raspberry Pi with Docker, we can build many. And three, it takes up no physical space.

Two, it enables Docker to do for the Pi what Docker does best for everything else: it makes software portable, easy to manage, and easy to replicate. One, it turns into software that which would otherwise be a hardware-only device that nobody has to remember to carry around (I'm always losing the peripheral cables).

Other than learning from the experience, Dockerizing an emulated Raspberry Pi enables us to do three things.

While commercial solutions exist, we will be building our own emulated cluster using a fully open source stack hosted on Google Compute Engine. Since the Raspberry Pi uses an ARM processor, this can make development problematic for those of us who work exclusively in the cloud. While the main value of these clusters comes from their size and low cost, their popularity makes them an increasingly common development platform. Innovation with the Raspberry Pi continues as they are turned into wi-fi extenders, security cameras, even bigger clusters, and more. And on the extreme end of the spectrum, Oracle built a 1060 node Raspberry Pi Cluster, which they introduced at Oracle OpenWorld 2019. Balena, built " The Beast", a 120 node Raspberry Pi cluster, for scaled testing of their online platform. David Guill built a 40-node Raspberry Pi Cluster that was intended to be part of his MSCE thesis. Interns at DataStax built a multi-datacenter, 32 nodes Cassenda fault-tolerance demo, complete with a big red button to simulate the failure of an entire datacenter.

Not long after the first Raspberry Pi was released in 2012, several set out to build them into low-cost clusters, often for research and testing purposes. It's even used administratively in production environments. The Raspberry Pi is no longer just a low-cost platform for students to learn computing, it's now a legitimate research and development platform that's used for IoT, networking, distributed systems, and software development. This guide discusses everything needed to build a simple, scalable, and fully binary compatible Raspberry Pi cluster using QEMU, Docker, Docker Compose, and Ansible.
