Raspberry Pi Github Actions runner with LXD

Github Actions are a very powerful tool to run tests and CI/CD tasks in the cloud. But what if you want to interact with some hardware or run on a different architecture altogether?

Enter self-hosted runners, those can be run just about anywhere, they register with Github and process jobs, same as the cloud based ones.

This video goes over how to setup such runners with LXD on both an X86 machine as well as a Raspberry Pi 4. LXD makes it easy to run on any architecture you want, with whatever resource restrictions is appropriate and with any attached hardware you'd like to use.
