基于Ubuntu的docker-machine映像

Question

Is there a possibility to simply create a docker-machine that is non-boot2docker based (ie, Ubuntu based) (which uses virtualbox driver)?

I would like to have full-featured Linux distro running the docker daemon on my mac instead of Tiny Core Linux distro which is fast and lightweight but doesn't offer me all the debugging facilities I need.

I know I can create it manually. I'm just wondering if there is a simple way such as docker-machine create is.

You could take advantage of the --virtualbox-boot2docker-url option.
This issue illustrates its usage (with an iso which is not a TinyCore one, but a RancherOS one )

docker-machine create -d virtualbox --virtualbox-boot2docker-url https://releases.rancher.com/os/latest/machine-rancheros.iso rancher

If RancherOS is a bit too bare, you can take some clues from how boot2docker is currently built , and build your own distro.

The key is to remove the parts not needed in order to be able to launch headless VM without using too much memory.

# Remove useless kernel modules, based on unclejack/debian2docker 
RUN cd $ROOTFS/lib/modules && \
rm -rf ./*/kernel/sound/* && \
rm -rf ./*/kernel/drivers/gpu/* && \
...
