I use a MacBook Air as my main laptop. I have been using Vagrant to test rust programs on linux. This feels a little heavy to me though as I have to create a Vagrant machine for each repository. The up and halt phases of the Vagrant box are a little slow and each machine eats away at my available hard drive space. I do not need an entire virutalized operating system, just a place to test my programs. This seems like a good use case for Docker.
