The latest release of Docker for Windows ("Docker Community Edition 18.06.0-ce-win70 2018-07-25") has officially deprecated AUFS with the following notice (https://docs.docker.com/docker-for-windows/release-notes/#docker-community-edition-18060-ce-win70-2018-07-25):

AUFS storage driver is deprecated in Docker Desktop and AUFS support will be removed in the next major release. You can continue with AUFS in Docker Desktop 18.06.x, but you will need to reset disk image (in Settings > Reset menu) before updating to the next major update. You can check documentation to save images and backup volumes

I'm thinking it's probably sane for us to follow suit and have 18.06.x be the final release that supports AUFS (especially since it repeatedly makes kernel upgrades / choosing a kernel version challenging).

Ok, let's do this. Release notes for 18.06.x officially updated: https://github.com/boot2docker/boot2docker/releases/tag/v18.06.0-ce

I'm going to leave this issue open for a bit as a catch-all to hopefully provide slightly better visibility for this change.

So far changing /var/lib/boot2docker/profile to overlay2

No issues loading an image and attaching a container.

Question. How does /var/lib/boot2docker/profile get created in a newly created vm. Does that come from docker-machine?

https://github.com/docker/machine/blob/master/libmachine/provision/boot2docker.go

if provisioner.EngineOptions.StorageDriver == "" { provisioner.EngineOptions.StorageDriver = "aufs" }

This default will need changing.

Thanks for the digging / info @kaosagnt! ❤️

I've filed docker/machine#4558 to discuss/update those references. 👍

Most likely, the same change should go into Minikube (even though it doesn't use Boot2Docker by default)

https://github.com/kubernetes/minikube/blob/master/pkg/minikube/machine/client.go#L113

			EngineOptions: &engine.Options{
				StorageDriver: "aufs",
				TLSVerify:     true,
			},

This was changed in Minishift already, although they went from "devicemapper" to "overlay2":
(it seems like the fallback code with the btrfs vs the aufs storage driver is never used anymore ?)

minishift/minishift#1961

Mostly because devicemapper falls back to "loopback" unless drives are partioned correctly...
But that's another story, anyway it (minishift) is now also using "overlay2" for the boot2docker.iso

https://github.com/minishift/minishift-centos-iso

centos-7.template:# update docker-storage to use overlay2 as default storage driver
centos-7.template:echo 'DOCKER_STORAGE_OPTIONS="--storage-driver overlay2"' > /etc/sysconfig/docker-storage
