instruction: Create a Kubernetes Pod configuration with best practices
output: ```dockerfile
  from another source (for example, log files or image
  overlays), the emptyDir may run out of capacity before this limit.
  Note:You can specify a size for memory backed volumes, provided that the SizeMemoryBackedVolumes
  feature gate
  is enabled in your cluster (this has been beta, and active by default, since the Kubernetes 1.22 release).
  If you don't specify a volume size, memory backed volumes are sized to node allocatable memory.
  Caution:Please check here
  for points to note in terms of resource management when using memory-backed emptyDir.
  emptyDir configuration example
  apiVersion: v1
  kind: Pod
  metadata:
   name: test-pd
  spec:
   containers:
   - image: registry.k8s.io/test-webserver
   name: test-container
   volumeMounts:
   - mountPath: /cache
   name: cache-volume
   volumes:
   - name: cache-volume
   emptyDir:
   sizeLimit: 500Mi
  fc (fibre channel)
  An fc volume type allows an existing fibre channel block storage volume
  to mount in a Pod. You can specify single or multiple target world wide names (WWNs)
  using the parameter targetWWNs in your Volume configuration. If multiple WWNs are specified,
  targetWWNs expect that those WWNs are
