Flex Volume failed to attach volume on Google Container Engine

[azhuo-va]

Torus version: torus_v0.1.2_darwin_amd64

I want to try torus on Google Container Engine, so I followed the instruction here to set up everything. I was able to create torus volume, but I got stuck at step 6.
I thought that was because torus's deriver wasn't installed on my kubernetes nodes. So I ssh into each node and ran these commands:

mkdir -p /usr/libexec/kubernetes/kubelet-plugins/volume/exec/coreos.com~torus/
wget https://github.com/coreos/torus/releases/download/v0.1.2/torus_v0.1.2_darwin_amd64.zip
unzip torus_v0.1.2_darwin_amd64.zip
cp torus_v0.1.2_darwin_amd64/torusblk /usr/libexec/kubernetes/kubelet-plugins/volume/exec/coreos.com~torus/torus
sudo /etc/init.d/kubelet restart
modprobe nbd nbds_max=32

Then I was told that dbus was missing, so I ran:

sudo apt-get update
sudo apt-get install dbus
sudo /etc/init.d/dbus restart

Then I re-tried step 6 but it failed again with the following reason:

This host is running on systemd? FlexVolume doesn't support non-systemd system as below:

https://github.com/coreos/torus/tree/master/contrib/kubernetes#1-install-torustorusblk-in-kubelet-volume-plugin-directory

NOTICE: The FlexVolume functionality currently uses systemd to manage its lifecycle. Running as a FlexVolume on non-systemd systems is TBD

is torus going to work on google container engine any time soon???
