 For this WordPress installation, we're going to configure our Kubernetes [pods](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/pods.md) to use [persistent disks](https://cloud.google.com/compute/docs/disks). This means that we can preserve installation state across pod shutdown and re-startup.

+Before doing anything else, we'll create the persistent disks that we'll use for the installation: one for the mysql pod, and one for the wordpress pod.
 The general series of steps required is as described [here](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/volumes.md), where $ZONE is the zone where your cluster is running, and $DISK_SIZE is specified as, e.g. '500GB'.  In future, this process will be more streamlined.
