LXD is an easy to use system container and virtual machine manager. On top of letting you create and run containers and virtual machines on a wide selection of storage and network options as well as featuring a modern REST API for remote management, it can also be very easily clustered. In this tutorial, we'll go over setting up LXD from scratch on 3 Raspberry Pi 4 and then configure it to allow remote systems to create and manage containers and virtual machines on those. Such a setup can be interacted with easily from the built-in command line tool available for Linux, macOS and Windows and can be shared with multiple users by using independent "projects" on that cluster. We'll also go over the most common web interface option to make it even easier to manage from any system on the network. This kind of setup can easily be replicated in the cloud or on any spare physical hardware and on the majority of hardware architectures. The Raspberry Pi 4 used in this case allows for someone to set such a redundant cluster for themselves at a very reasonable cost, making it a perfect way to experiment.
