I am running a Windows7 (64-bit) machine having vmplayer , which hosts Fedora 25 . I have installed docker CE on it and my examples till now have worked fine. The issue is when trying to run docker-machine examples. As per my understanding, it is required to create hosts for docker. While it makes sense to have it on Windows and Mac but do I need it on Linux ? What even adds to confusion is, how come all the examples I tried till now have worked fine? Another point is, if docker-machine is not part of Linux docker distribution; then how do we create multiple docker hosts on Linux ?

Is docker-machine required on linux?
