"Emulator" is not the word - it should have been "simulator". From an emulator I expect the ability to run all the usual Linux commands, or at least all the docker commands (this can be already done, maybe even just with JS [1]). Had they called it a "simulator" from the beginning and my expectations wouldn't have been so high. I understand the "type the correct string and go to the next step" kind of tutorial, but as someone who is used to the Linux shell and had heard about Docker, but never used it, it's a bit frustrating to finish the tutorial and not be able to play around a bit with the "simulator" to test Docker without having to install it. Anyway, I suppose it serves the purpose of "getting started". [1] http://bellard.org/jslinux/ http://bellard.org/jslinux/
