instruction: Create a Kubernetes Pod configuration with best practices
output: ```dockerfile
  from being loaded by the controller manager and the kubelet, you need to set InTreePluginvSphereUnregister feature flag to true. You must install a csi.vsphere.vmware.com CSI driver on all worker nodes.
  Using subPath
  Sometimes, it is useful to share one volume for multiple uses in a single pod.
  The volumeMounts[*].subPath property specifies a sub-path inside the referenced volume
  instead of its root.
  The following example shows how to configure a Pod with a LAMP stack (Linux Apache MySQL PHP)
  using a single, shared volume. This sample subPath configuration is not recommended
  for production use.
  The PHP application's code and assets map to the volume's html folder and
  the MySQL database is stored in the volume's mysql folder. For example:
  apiVersion: v1
  kind: Pod
  metadata:
   name: my-lamp-site
  spec:
   containers:
   - name: mysql
   image: mysql
   env:
   - name: MYSQL_ROOT_PASSWORD
   value: "rootpasswd"
   volumeMounts:
   - mountPath: /var/lib/mysql
   name: site-data
   subPath: mysql
   - name: php
   image: php:7.0-apache
   volumeMounts:
   - mountPath: /var/www/html
   name: site-data
   subPath: html
   volumes:
   - name: site-data
   persistentVolumeClaim:
   claimName: my-lamp-site-data
