only OS X Docker client exist. "The Docker Engine uses Linux-specific kernel features, so to run it on OS X we need to use a lightweight virtual machine (vm). You use the OS X Docker client to control the virtualized Docker Engine to build, run, and manage Docker containers. To make this process easier, we've designed a helper application called Boot2Docker that installs the virtual machine and runs the Docker daemon." https://docs.docker.com/installation/mac/ https://docs.docker.com/installation/mac/
