Docker example
This Vagrant file deploys a small VM (1GB and 1CPU) with cinderlib in a container and with LVM properly configured to be used by the container.
This makes it really easy to use the containerized version of cinderlib:
$ vagrant up
$ vagrant ssh -c 'sudo docker exec -it cinderlib python'
Once we've run those two commands we are in a Python interpreter shell and can run Python code to use the LVM backend:
import cinderlib as cl
# Initialize the LVM driver
= cl.Backend(volume_driver='cinder.volume.drivers.lvm.LVMVolumeDriver',
lvm ='cinder-volumes',
volume_group='iscsi',
target_protocol='lioadm',
target_helper='lvm_iscsi')
volume_backend_name
# Create a 1GB volume
= lvm.create_volume(1)
vol
# Export, initialize, and do a local attach of the volume
= vol.attach()
attach
print('Volume %s attached to %s' % (vol.id, attach.path))
# Detach it
vol.detach()
# Delete it
vol.delete()
