instruction: Create a Kubernetes Pod configuration with best practices
output: ```dockerfile
  from the existing in-tree plugin to the
  pxd.portworx.com Container Storage Interface (CSI) Driver.
  Portworx CSI Driver
  must be installed on the cluster.projectedA projected volume maps several existing volume sources into the same
  directory. For more details, see projected volumes.rbd (removed)Kubernetes 1.32 does not include a rbd volume type.The Rados Block Device (RBD) in-tree storage driver
  and its csi migration support were deprecated in the Kubernetes v1.28 release
  and then removed entirely in the v1.31 release.secretA secret volume is used to pass sensitive information, such as passwords, to
  Pods. You can store secrets in the Kubernetes API and mount them as files for
  use by pods without coupling to Kubernetes directly. secret volumes are
  backed by tmpfs (a RAM-backed filesystem) so they are never written to
  non-volatile storage.Note:You must create a Secret in the Kubernetes API before you can use it.A Secret is always mounted as readOnly.A container using a Secret as a subPath volume mount will not
  receive Secret updates.For more details, see Configuring Secrets.vsphereVolume (deprecated)In Kubernetes 1.32, all operations for the in-tree vsphereVolume type
  are redirected to the csi.vsphere.vmware.com CSI driver.The vsphereVolume in-tree storage driver was deprecated in the Kubernetes v1.19 release
  and then removed entirely in the v1.30 release.The Kubernetes project suggests that you use the
  vSphere CSI
  third party storage driver instead.Using subPathSometimes, 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
  Using subPath with expanded environment variablesFEATURE STATE:
  Kubernetes v1.17 [stable]Use the subPathExpr field to construct subPath directory names
