-# 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
