+# MySQL installation with cinder volume plugin
+
+Cinder is a Block Storage service for OpenStack. This example shows how it can be used as an attachment mounted to a pod in Kubernets.
+
+### Prerequisites
+
+Start kubelet with cloud provider as openstack with a valid cloud config
+Sample cloud_config:
+
+```
+[Global]
+auth-url=https://os-identity.vip.foo.bar.com:5443/v2.0
+username=user
+password=pass
+region=region1
+tenant-id=0c331a1df18571594d49fe68asa4e
+```
+
+Currently the cinder volume plugin is designed to work only on linux hosts and offers ext4 and ext3 as supported fs types
+Make sure that kubelet host machine has the following executables
+
+```
+/bin/lsblk -- To Find out the fstype of the volume
+/sbin/mkfs.ext3 and /sbin/mkfs.ext4 -- To format the volume if required
+/usr/bin/udevadm -- To probe the volume attached so that a symlink is created under /dev/disk/by-id/ with a virtio- prefix
+```
+
+Ensure cinder is installed and configured properly in the region in which kubelet is spun up
+
+### Example
+
+Create a cinder volume Ex:
+
+`cinder create --display-name=test-repo 2`
+
+Use the id of the cinder volume created to create a pod [definition](mysql.yaml)
+Create a new pod with the definition
+
+`cluster/kubectl.sh create -f examples/mysql-cinder-pd/mysql.yaml`
+
+This should now
+
+1. Attach the specified volume to the kubelet's host machine
+2. Format the volume if required (only if the volume specified is not already formatted to the fstype specified)
+3. Mount it on the kubelet's host machine
+4. Spin up a container with this volume mounted to the path specified in the pod definition
+
