Enhanced version of LVM flexVolume driver for Kubernetes.

lvm-flexvolume provides a LVM driver with Thin Provisioning support. It will allocate LV from a previously created VG/Thinpool and mount it for usage in a container.

• can create LV if does not exist
• support for thin provisioned logical volumes
• support for optional mount options

• Make sure kubelet is running with --enable-controller-attach-detach=false
• Create the directory /usr/libexec/kubernetes/kubelet-plugins/volume/exec/sysoperator.pl~lvm
• Install driver as /usr/libexec/kubernetes/kubelet-plugins/volume/exec/sysoperator.pl~lvm/lvm

Create a Kubernetes Pod such as:

cat examples/nginx.yaml | kubectl apply -f -

The driver will create a logical volume and the volume will also be mounted as /data inside the container.

Following options are required:

• volumeID - Name of logical volume.
• size - Size to allocate for the new logical volume. Accepts any value supported by --size parameter of lvcreate.
• volumegroup - Name of volume group.

Optional options may be passed:

• thinpool - Name of thin pool.
• mountoptions - Additional options passed to mount. (e.g. noatime)
