In this recipe, we will deploy Wordpress using dynamic persistent volumes created by the Rook Ceph block storage provider. Let's perform the following steps:

1. Clone the examples repository:

$ git clone https://github.com/k8sdevopscookbook/src.git
$ cd src/chapter5/rook/

2. Review both mysql.yaml and wordpress.yaml. Note that PVCs are using the rook-ceph-block storage class:

$ cat mysql.yaml && cat wordpress.yaml

3. Deploy MySQL and WordPress:

$ kubectl apply -f mysql.yaml 
$ kubectl apply -f wordpress.yaml

4. Confirm the persistent volumes created:

$ kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
pvc-eb2d23b8-d38a-11e9-88a2-a2c82783dcda 20Gi RWO Delete Bound default/mysql-pv-claim rook-ceph-block 38s
pvc-eeab1ebc-d38a-11e9-88a2-a2c82783dcda 20Gi RWO Delete Bound default/wp-pv-claim rook-ceph-block 38s

5. Get the external IP of the WordPress service:

$ kubectl get service
NAME            TYPE         CLUSTER-IP  EXTERNAL-IP  PORT(S)      AGE
kubernetes      ClusterIP    10.0.0.1    <none>       443/TCP      6h34m
wordpress       LoadBalancer 10.0.102.14 13.64.96.240 80:30596/TCP 3m36s
wordpress-mysql ClusterIP    None        <none>       3306/TCP     3m42s

6. Open the external IP of the WordPress service in your browser to access your Wordpress deployment:

Now you know how to get the popular WordPress service, with persistent storage stored on Rook-based Ceph storage, up and running.
