Technical requirements
As in previous chapters, we will continue to use our local Docker installations. Again, the screenshots in this chapter will be from my preferred operating system, macOS. We will be looking at how we can use Docker Machine to launch Docker-based virtual machines (VMs) locally using VirtualBox, as well as in public clouds, so you will need an account with DigitalOcean if you would like to follow along with the examples in this chapter.
As before, the Docker commands we will be running will work on all three operating systems on which we have installed Docker so far. However, some of the supporting commands, which will be few and far between, may only apply to macOS- and Linux-based operating systems.
