According to the official docker docs,

Docker Machine is a tool that lets you install Docker Engine on virtual hosts, and manage the hosts with docker-machine commands.

Since docker engine can be directly installed on Linux, my question is whether there are any use cases where docker-machine is actually needed when working on a Linux environment

If you want to just run small tests on your machine, you should not need it.

It becomes useful when you want to provision other hosts, it may be a virtual machine running on your computer or a remote host.

Why would you want to do this? I can think of 2 cases.

  • You can have different virtual hosts with different versions of your system and you can just pause/start them as a whole.
  • You may need a bigger machine than your own computer. Even more if you are working on a laptop, it's easy to run out of 16GB (maybe 32?) of ram if you start deploying multiple services.
