Kubernetes hands-on

We learned how to install the Kubernetes cluster in the previous section. Now, let's create a more complex example with Kubernetes. In this application, we will deploy an application running a WordPress site and MySQL database using official Docker images.

1. Create a persistent volume. Both WordPress and MySQL will use this volume to store data. We will create two local persistent volumes of size 5 GB each. Copy the following content to the volumes.yaml file:

apiVersion: v1kind: PersistentVolumemetadata:  name: pv-1  labels:    type: localspec:  capacity:    storage: 5Gi  accessModes:    - ReadWriteOnce  hostPath:    path: /tmp/data/pv-1  storageClassName: slow ---apiVersion: v1kind: PersistentVolumemetadata:  name: pv-2  labels:    type: localspec:  capacity:    storage: 5Gi  accessModes:    - ReadWriteOnce  hostPath:    path: /tmp/data/pv-2  storageClassName: slow 

2. Now, create the volume by running the following command:

        $ kubectl create -f volumes.yaml         persistentvolume...
