There is one more important component sitting next to Hyperkit, rightly called as VPNKit. VPNKit is a part of HyperKit attempts to work nicely with VPN software by intercepting the VM traffic at the Ethernet level, parsing and understanding protocols like NTP, DNS, UDP, TCP and doing the “right thing” with respect to the host’s VPN configuration. VPNKit operates by reconstructing Ethernet traffic from the VM and translating it into the relevant socket API calls on OSX. On macOS High Sierra, the default file system is APFS.With the recent release, NFS Volume sharing has been enabled both for Swarm & Kubernetes.

To this end, osxfs features a number of unique capabilities as well as differences from a classical Linux file system.On macOS Sierra and lower, the default file system is HFS+. osxfs provides a close-to-native user experience for bind mounting macOS file system trees into Docker containers. The osxfs is a new shared file system solution, exclusive to Docker for Mac. Just sitting next to HyperKit is Filesystem sharing solution. It is designed to be interfaced with higher-level components such as the VPNKit and DataKit.

It includes a complete hypervisor optimized for lightweight virtual machines and container deployment. HyperKit is basically a toolkit for embedding hypervisor capabilities in your application. It is built on top of amework in OS X 10.10 Yosemite and higher, runs entirely in userspace, and has no other dependencies.

Under this blog, I will deep dive into Docker for Mac architecture and show how to access service containers running on top of LinuxKit VM.Īt the base of architecture, we have hypervisor called Hyperkit which is derived from xhyve. The xhyve hypervisor is a port of bhyve to OS X. Top 5 Exclusive Features of Docker For Mac That You Can’t Afford to Ignore It provides binfmt_misc multi architecture support, so you can run containers for different Linux architectures, such as arm, mips, ppc64le, and even s390x.

Docker for Mac has now Multi-Architectural support.

This interface is actually within the virtual machine.

There is no docker0 bridge on macOS. Because of the way networking is implemented in Docker for Mac, you cannot see a docker0 interface on the host.

When you install Docker for Mac, machines created with Docker Machine are not affected.

This is the default location Docker and Docker Compose clients use to connect to the Docker daemon, so you to use docker and docker-compose CLI commands on your Mac. The Docker Engine API is exposed on a socket available to the Mac host at /var/run/docker.sock.

Docker for Mac does not use docker-machine to provision its VM.

Hyperkit is a lightweight macOS virtualization solution built on top of amework in macOS 10.10 Yosemite and higher.

Docker for Mac uses HyperKit instead of Virtual Box.

The way the filesystem sharing maps OSX volumes seamlessly into Linux containers and remapping macOS UIDs into Linux is one of the most anticipated feature. One of the most amazing feature about Docker for Mac is “drag & Drop” the Mac application to /Applications to run Docker CLI and it just works flawlessly. At installation time, it creates symlinks in /usr/local/bin for docker & docker-compose and others, to the commands in the application bundle, in /Applications/Docker.app/Contents/Resources/bin. It embeds a hypervisor (based on xhyve), a Linux distribution which runs on LinuxKit and filesystem & network sharing that is much more Mac native. It is a Mac native application, that you install in /Applications. It runs on a LinuxKit VM and NOT on VirtualBox or VMware Fusion.

Docker is a full development platform for creating containerized apps, and Docker for Mac is the most efficient way to start and run Docker on your MacBook.
