convoy_full_installation.sh

# install convoy

wget https://github.com/rancher/convoy/releases/download/v0.5.2/convoy.tar.gz
tar xvzf convoy.tar.gz
sudo cp convoy/convoy convoy/convoy-pdata_tools /usr/local/bin/
sudo mkdir -p /etc/docker/plugins/
sudo bash -c 'echo "unix:///var/run/convoy/convoy.sock" > /etc/docker/plugins/convoy.spec'

# download and execute preparation script

wget https://raw.githubusercontent.com/rancher/convoy/master/tools/dm_dev_partition.sh
bash dm_dev_partition.sh --write-to-disk $DISK_MOUNTPOINT

# unmount disk
umount $DISK_MOUNTPOINT

# copy-paste last string of the output 
# or just run:

convoy daemon --drivers devicemapper --driver-opts dm.datadev=$DISK_MOUNTPOINT\1 --driver-opts dm.metadatadev=$DISK_MOUNTPOINT\2 &

# now you should be able to create volumes using convoy driver:
docker volume create --driver convoy --opt size=100m test
