cinderlib/examples/docker

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
lvm = cl.Backend(volume_driver='cinder.volume.drivers.lvm.LVMVolumeDriver',
                 volume_group='cinder-volumes',
                 target_protocol='iscsi',
                 target_helper='lioadm',
                 volume_backend_name='lvm_iscsi')

# Create a 1GB volume
vol = lvm.create_volume(1)

# Export, initialize, and do a local attach of the volume
attach = vol.attach()

print('Volume %s attached to %s' % (vol.id, attach.path))

# Detach it
vol.detach()

# Delete it
vol.delete()
