Howdy,

Why is it "better" is not really the right question - it does things differently (very differently) and depending on what you are wanting to do would determine if it was better (for you) or not.

VMware, Proxmox, Hyper-V, virtualbox, etc are all about slicing a machine up to run multiple "machines" on a single physical machine. So you need to manage devices, OSes, etc inside the virtualised environment. Some of those are better than others because, of features like machines floating between 2 physical machines, virtual networking, etc.

Docker is an application runtime environment and the analogy is "live CD". An application is "built" into an image, and the imagine doesnt change. So everytime you start the image anything inside it from last time is lost. If there is important data you need to keep, then you need to put that data on a persistent mount (analogy think USB stick that is used with the live CD).

What's good about the image, is it has everything it needs to run the application and it can run anywhere the docker runtime is installed (for the architecture of the application). As a example, I run Synchronet on my MAC while I code in javascript (for my videotex interface), but then deploy the same image on my linux host when I run it live. If you ran docker on Windows, that same image would work as well.
