Developing on Apple M1 Silicon with Virtual Environments
Docker containers all the way down - In my article Creating Repeatable Development Environments, I showed how I use Vagrant as an orchestrator and VirtualBox as a provider of virtual machines for creating consistent development environments for my students and development teams. That worked really well until Apple released their new 2020 Macs with Apple M1 Silicon chips based on the ARM architecture. I had selected VirtualBox because it was free and supports Mac, Linux, and Windows, but it only runs on Intel computers (x86_64 architecture) and Apple Silicon is ARM base (aarch64 architecture). As it turns out, 8 of my students showed up for the 2021 spring semester with Apple M1 Macs which meant that all of my labs based on VirtualBox were not going to work for them. I need another solution and I needed it fast.
