CSI Hostpath driver

Usage:

Build hostpathplugin

$ make hostpath

Start Hostpath driver

$ sudo ./_output/hostpathplugin --endpoint tcp://127.0.0.1:10000 --nodeid CSINode -v=5

Test using csc

Get csc tool from https://github.com/rexray/gocsi/tree/master/csc

Get plugin info

$ csc identity plugin-info --endpoint tcp://127.0.0.1:10000
"csi-hostpath"  "0.1.0"

Create a volume

$ csc controller new --endpoint tcp://127.0.0.1:10000 --cap 1,block CSIVolumeName
CSIVolumeID

Delete a volume

$ csc controller del --endpoint tcp://127.0.0.1:10000 CSIVolumeID
CSIVolumeID

Validate volume capabilities

$ csc controller validate-volume-capabilities --endpoint tcp://127.0.0.1:10000 --cap 1,block CSIVolumeID
CSIVolumeID  true

NodePublish a volume

$ csc node publish --endpoint tcp://127.0.0.1:10000 --cap 1,block --target-path /mnt/hostpath CSIVolumeID
CSIVolumeID

NodeUnpublish a volume

$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/hostpath CSIVolumeID
CSIVolumeID

Get NodeID

$ csc node get-id --endpoint tcp://127.0.0.1:10000
CSINode
