I really, really, don't understand the docker fixation, but maybe I'm missing something.

The most important function of docker, IMHO, is that it standardizes the creation of a VM using Virtualbox across platforms.

Unless Amazon AWS, DigitalOcean, GoogleCompute, etc. allow a docker image (aka a VirtualBox image) to run directly on their base virtualization platform (without me putting together an AMI or whatever on their platform), this just adds another layer of virtualization that I can do without. Do they do this already?

If and when they do that, docker would be tremendously useful because I wouldn't need to rebuild my image for that particular platform (AWS/DO/GC).

And if they do that already, then why aren't they just accepting existing popular VM images (VMWare/VirtualBox)?

Nice one. However, VirtualBox's shared-folder support is so god-awfully slow, that here at work we all swapped out the regular boot2docker setup for boot2docker-xhyve[0] which is so much faster at nearly everything that it's not even a comparison. Now, with ailispaw's dockeroot-xhyve you can even get a VM root image that can be grown on the fly, so you never run out of space on your VM when building large Docker imag…

Has anyone tried VMWare fusion to run a Docker host VM?

Virtualbox shared folders are unusable for my purpose (compiling software on Linux).

Yes, and I think its much worse in terms of reliability. When I save a file (say a Gemfile), sometimes only half of it shows up inside the container.

Anybody know what would cause VMWare Fusion (or any VM for that matter) to behave this way?

AWS supports deploying Docker images on both Elastic Beanstalk and their new Elastic Container Service. While it doesn't completely remove the need to worry about VMs, it does abstract them away somewhat (ECS much more so).

Does the docker image run directly on their base virtualization platform or does it run on top of another OS (that I install) that runs on their virtualization platform? I have an OS in my docker image already, so..

Docker Machine alone knocks out the entire list of hosts you laid out: https://docs.docker.com/machine/

For more sophisticated scheduling needs there is http://www.replicated.com/, https://cloud.google.com/container-engine/, and https://aws.amazon.com/ecs/

Related to what you say about "don't VM's solve this problem?" is a project called https://hyper.sh. They're coming at it from the angle that if VM's can boot really fast, containers are a moot point.

So docker machine will create an image for that particular host (AWS/DO/GC...) and create a docker image on TOP of that, correct? It solves the problem of me configuring multiple hosts, but there's still an extra OS layer in there, isn't it?

Docker under OSX is a real pain to solve ASAP. I've set Docker on my Linux machine and it's working like a charm. Then I had to do the same for my coworkers running OSX, the vbox shared folders are definitely unusable. Now it's been few days that I'm trying to find the best way to have a two-way sync in order to sync back changes from docker to the OSX folder (eg. when you upload a file and it's saved in the /public…

There's https://github.com/codekitchen/dinghy if you want to mount the Mac host volumes inside boot2docker via NFS. We have a Vagrantfile that does this, but dinghy packages it all up nicely.

At the end of the day though, Docker as a development environment is really bad on OS X until a VM vendor fixes file share performance. I really wish Docker would make it a priority to have decent Mac support.

I use docker for development on Mavericks using vagrant + coreos as the host VM and things works nicely [0]. NFS shared folders performance is fine and the configuration is trivial.

I appreciate the Toolbox suite as I use most of them. But I am concerned though not surprised how this make the "batteries included but removable" motto more insignificant as it becomes more unlikely that people will use alternatives.
