Does docker machine have the overhead of executing docker on top of a virtual machine?

Question

It's a totally waste to use docker machine if my Linux distribution supports docker natively because I don't need to use a virtual machine to run docker. Is that right?

Answer 1

Yes, that's correct. docker-machine will help you provision Docker within a virtual guest using one of the supported hypervisors, but otherwise it's not necessary on Linux systems that have the required kernel support for Docker.
