@tormeh look at a Docker just like at a system that gets you the images (in "tar" archives) from the Docker Hub repo (or build them by yourself) and lets you run these "tar" images by leveraging the cgroups (Linux kernel abstraction feature that limits, isolates resource usage of a process). You may basically look at a Docker like at "chroot-on-steroids". And yes, it helps to run the images wherever you have Docker installed. There are few limitations though, especially when it comes to the point one needs to pass something from the host into a container (e.g. driver libraries, devices, special system paths or environment variables), since they may differ from distro to distro, from Platform to Platform.
