The kubelet doesnt manage containers which were not created by Kubernetes.On top of Kubelet, we have kubernetes services running.

It runs on a LinuxKit VM and NOT on VirtualBox or VMware Fusion.

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.

At installation time, it creates symlinks in usrlocalbin for docker docker-compose and others, to the commands in the application bundle, in ApplicationsDocker.appContentsResourcesbin.

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.

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

The Docker Engine API is exposed on a socket available to the Mac host at varrundocker.sock.

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.

Because of the way networking is implemented in Docker for Mac, you cannot see a docker0 interface on the host.

It provides binfmtmisc multi architecture support, so you can run containers for different Linux architectures, such as arm, mips, ppc64le, and even s390x.

It is built on top of Hypervisor.framework in OS X 10.10 Yosemite and higher, runs entirely in userspace, and has no other dependencies.

HyperKit is basically a toolkit for embedding hypervisor capabilities in your application.

It includes a complete hypervisor optimized for lightweight virtual machines and container deployment.

It is designed to be interfaced with higher-level components such as the VPNKit and DataKit.

The osxfs is a new shared file system solution, exclusive to Docker for Mac.

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.

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 hosts VPN configuration.

VPNKit operates by reconstructing Ethernet traffic from the VM and translating it into the relevant socket API calls on OSX.

This allows the host application to generate traffic without requiring low-level Ethernet bridging support.

The docker-for-mac.yml contains an example use of the open source components of Docker for Mac.

The example has support for controlling dockerd from the host via vsudd and port forwarding with VPNKit.

It requires HyperKit, VPNKit and a Docker client on the host to run.

If you are new to K8s, kubelet is an agent that runs on each node in the cluster.

It basically takes a set of PodSpecs that are provided through various mechanisms and ensures that the containers described in those PodSpecs are running and healthy.
