Overview

Docker for Mac is an integrated, easy-to-deploy environment for building, assembling, and shipping applications from a Mac, Docker for Mac is a native Mac application architected from scratch, with a native user interface and auto-update capability, deeply integrated with OS X native virtualization, Hypervisor Framework, networking and file system, making it faster and more reliable than previous ways of getting Docker on a Mac.

With Docker for Mac, volume data access works correctly, including file change notifications enabling edit/test cycles for "in container" development. It includes a DNS server for containers, and is integrated with the Mac OS X networking system so that Docker can be used even when connected to a very restrictive corporate VPN.

Ever since I started hearing about Docker, I keep thinking it's a solution in search of a problem. OK, it's a virtualization technology that doesn't require you to install a guest OS, which is cool, I think, but the configuration needed to get apps installed is every bit as complicated that installing a virtualization engine (VitualBox, Parallels, VMware Fusion) and putting an OS on it. Yes, it's cool to see a non-Mac app running "natively" on Mac hardware, but if the app is the thing (and in Docker, that's the whole point), then I can put up a virtual machine, OS and app in less time than it takes me to put up a Docker registry item, download it and maintain it. If your thing is microservices, then Docker may be a good choice, but then why use a Mac? This is not a review, but a comment and question. Technology for technology's sake, it seems...
