how can I use gluster-containers as Gluster PersistentVolume with gluster-server deployed in kubernetes?

[imwower]

hello, I deployed gluster server within kubernetes, and the pods work well, I can mount the gluster-volume in the gluster-client pod with docker image : gluster/glusterfs-client, here is the script within gluster-client:

  mkdir -p /mnt/glusterfs/
  #the gluster1 is one of the gluster server:
  mount -t glusterfs gluster1:/k8s-volume /mnt/glusterfs/
  touch /mnt/glusterfs/demo.txt

this works well.
but how can I add Gluster PersistentVolume using this gluster-server? what's the Gluster Endpoint here?

• because Gluster server need Endpoint from kubernetes, and the Endpoint.yaml must use ip address to config gluser peers, the doc: https://docs.openshift.com/container-platform/3.4/install_config/storage_examples/gluster_example.html
• but kubernetes just have the hostname for the pods, the ip may change in furture
