How to test CSI driver in local environment

Install csc tool according to https://github.com/rexray/gocsi/tree/master/csc

$ mkdir -p $GOPATH/src/github.com
$ cd $GOPATH/src/github.com
$ git clone https://github.com/rexray/gocsi.git

Start CSI driver locally

$ cd $GOPATH/src/github.com/kubernetes-csi/csi-driver-iscsi
$ ./_output/iscsiplugin --endpoint tcp://127.0.0.1:10000 --nodeid CSINode -v=5 &
  • Get plugin info
$ csc identity plugin-info --endpoint "$endpoint"
"iscsi.csi.k8s.io"    "v2.0.0"
  • Publish an iscsi volume
$ export ISCSI_TARGET="iSCSI Target Server IP (Ex: 10.10.10.10)"
$ export IQN="Target IQN"
$ csc node publish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/iscsi --attrib targetPortal=$ISCSI_TARGET --attrib iqn=$IQN --attrib lun=<lun-id> iscsitestvol
iscsitestvol
  • Unpublish an iscsi volume
$ csc node unpublish --endpoint tcp://127.0.0.1:10000 --target-path /mnt/iscsi iscsitestvol
iscsitestvol
  • Validate volume capabilities
$ csc controller validate-volume-capabilities --endpoint "$endpoint" --cap "$cap" "$volumeid"
  • Get NodeID
$ csc node get-info --endpoint "$endpoint"
