instruction: Create a Kubernetes Pod configuration with best practices
output: ```dockerfile
  from the host); if something already exists at
  that path and isn't a regular file, the Pod fails.Here's the example manifest:apiVersion: v1
  kind: Pod
  metadata:
   name: test-webserver
  spec:
   os: { name: linux }
   nodeSelector:
   kubernetes.io/os: linux
   containers:
   - name: test-webserver
   image: registry.k8s.io/test-webserver:latest
   volumeMounts:
   - mountPath: /var/local/aaa
   name: mydir
   - mountPath: /var/local/aaa/1.txt
   name: myfile
   volumes:
   - name: mydir
   hostPath:
   # Ensure the file directory is created.
   path: /var/local/aaa
   type: DirectoryOrCreate
   - name: myfile
   hostPath:
   path: /var/local/aaa/1.txt
   type: FileOrCreate
  imageFEATURE STATE:
  Kubernetes v1.33 [beta] (enabled by default: false)An image volume source represents an OCI object (a container image or
  artifact) which is available on the kubelet's host machine.An example of using the image volume source is:pods/image-volumes.yaml
  apiVersion: v1
  kind: Pod
  metadata:
   name: image-volume
  spec:
   containers:
   - name: shell
   command: ["sleep", "infinity"]
   image: debian
   volumeMounts:
   - name: volume
   mountPath: /volume
   volumes:
   - name: volume
   image:
   reference: quay.io/crio/artifact:v2
   pullPolicy: IfNotPresent
  The volume is resolved at pod startup depending on which pullPolicy value is
  provided:Alwaysthe kubelet always attempts to pull the reference. If the pull fails,
  the kubelet sets the Pod to Failed.Neverthe kubelet never pulls the reference and only uses a local image or artifact.
  The Pod becomes Failed if any layers of the image aren't already present locally,
  or if the manifest for that image isn't already cached.IfNotPresentthe kubelet pulls if the reference isn't already present on disk. The Pod becomes
  Failed if the reference isn't present and the pull fails.The volume gets re-resolved if the pod gets deleted and recreated, which means
  that new remote content will become available on pod recreation. A failure to
  resolve or pull the image during pod startup will block containers
