# Persistent Installation of MySQL and WordPress on Kubernetes
This example describes how to run a persistent installation of [Wordpress](https://wordpress.org/) using the [volumes](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/volumes.md) feature of Kubernetes, and [Google Compute Engine](https://cloud.google.com/compute/docs/disks) [persistent disks](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/docs/volumes.md#gcepersistentdisk).
This example describes how to run a persistent installation of [Wordpress](https://wordpress.org/) using the [volumes](/docs/volumes.md) feature of Kubernetes, and [Google Compute Engine](https://cloud.google.com/compute/docs/disks) [persistent disks](/docs/volumes.md#gcepersistentdisk).
We'll use the [mysql](https://registry.hub.docker.com/_/mysql/) and [wordpress](https://registry.hub.docker.com/_/wordpress/) official [Docker](https://www.docker.com/) images for this installation. (The wordpress image includes an Apache server).

For this WordPress installation, we're going to configure our Kubernetes [pods](http://docs.k8s.io/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.
You will need to create the disks in the same [GCE zone](https://cloud.google.com/compute/docs/zones) as the Kubernetes cluster. The `cluster/kube-up.sh` script will create the cluster in the `us-central1-b` zone by default, as seen in the [config-default.sh](https://github.com/GoogleCloudPlatform/kubernetes/blob/master/cluster/gce/config-default.sh) file. Replace `$ZONE` below with the appropriate zone.

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](http://docs.k8s.io/volumes.md), where $DISK_SIZE is specified as, e.g. '500GB'. In future, this process will be more streamlined.
