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.
