Docker For Mac Vs Parrells4/18/2021
Docker for Mac is a complete development environment deeply integrated with the Mac OS Hypervisor framework, networking, and filesystem.Docker for Mac is the fastest and most reliable way to run Docker on a Mac.There is also Docker Toolbox which is not a packaged Mac app but rather is a pure command line tool thatI believepredates Docker Desktop as explained here.
Docker Vs Parrells Mac OS Hypervisor FrameworkAt installation time, Toolbox uses docker-machine to provision a VirtualBox VM called default, running the boot2docker Linux distribution, with Docker Engine with certificates located on your Mac at HOME.dockermachinemachinesdefault.

For example, in order for a Container to readwrite from your Host OS hard drive, it has to. For example, in order for a VM to readwrite from your Host OS hard drive, it has to. All that synchronizing work between these layers is not trivial. While it is true that Docker on Linux is the architecture as intended (and therefore is the best experience), simply switching is not tenable for most folks. At the very least, the jet plane taking off might only happen every once in a while versus all the time. You wont have to worry about the details though, as they package it as part of the Docker for Mac Edge build. It is, in effect, another abstraction layer to speed up the process. As it proved out its utility, it was eventually ported to macOS and Windows. This unfortunately results in these low-level inefficiencies that we otherwise take for granted. I decided to setup a Linux VM on Mac and install my Docker dev environment on the Linux VM. ![]() Im using Parallels Desktop which is a lot more performant than Virtual Box so that could also help things as well. I havent seen or heard of anyone else doing this but it was the only way for me to get my dev environment to run from my Mac without running out of resources. I knew that Docker for Mac OS was different and running inside a VM, but not with such details. However IMHO there is a little bit of exageration: it is working correctly on my machine, and the overhead in comparison with the Linux setup is not such a pain. We have a pretty IO heavy setup with our front-end (i.e. Checking my Activity Monitor right now, at idle, my docker.hyperkit on my MBP sits at 40.and thats with help from docker-sync. After a comparison that I did running Docker on Linux, the MacOS version (Including the use of NFS volumes) is too slow. If indeed the case generally, Docker devs should suggest such a solution, rather than providing a substandard VM of their own for MacOS. Im hearing these reports after learning of Doki malware and Im losing confidence in the product. Or should I say Im losing faith in the organization behind the product. Whereas Microsoft was cooperative in creating a bridge to their kernel with WSL-2, Apple generally keeps macOS under lock and key. Docker for Mac will be at the mercy of the macOS Hyperkit. Looks like Mutagen integration isnt happening now so I think Ill try the Linux VM as well.
