Lets take a look at what this means, a brief history of developer tooling and then cover my first impressions as I kick the tyres.

This has been a journey and we didnt start day one with Kubernetes support in Docker for Mac, so lets look at the context.

Docker Io Performance Install A Linux

They would need to install a Linux host manually and then set up shared folders.

Sometimes people also use vagrant from Hashicorp to provide a consistent CLI between VM host software.

Docker Io Performance Plus A Writeable

Docker Machine automated the setup of a virtual machine on a local or remote environment and made use of standard ISO images ( boot2docker ) plus a writeable disk area.

This also meant upgrading from one version to another was easy.

It could support multiple-concurrent Docker versions or hosts at the same time for clustering.

Docker for MacWindows or DfM was pitched as a native integration which meant it came with a UI and a menu-bar that was hugely popular.

The initial release of DfM was through a limited beta and there was a big demand on Twitter for it.

Its primary purpose is to create a single-node Kubernetes cluster which also includes a Docker host that can be used for development.

Lets move onto my first impressions of Kubernetes on Docker for Mac.

The support is then downloaded via a UI option and this can take several minutes.

By default parts of the Kubernetes ecosystem run as containers in a hidden namespace called system.

This is in effect the same as what is running for Docker Swarm, but its hidden from you and baked into a few fixed binaries rather than being split out to this degree.

Server Version: version.InfoMajor:1, Minor:8, GitVersion:v1.8.2, GitCommit:bdaeafa71f6c7c04636251031f93464384d54963, GitTreeState:clean, BuildDate:2017-10-24T19:38:10Z, GoVersion:go1.8.3, Compiler:gc, Platform:linuxamd64.

This will help the community maintain and build the Kubernetes integration for OpenFaaS.

For example the original Swarm that ran as individual containers is still supported by Dockers UCP product.

Im really impressed with what Docker has done with Docker for Mac and the internal components that make it up like LinuxKit.
