Best practices re: pushing data to persistent block volumes (OpenEBS cStor/mayaStor)?

If I need to push data to a volume (for example, an updated static webpage file, or configuration files for the pod/container), what is the best practice in doing so with block volumes like cStor or mayaStor? This wasn’t really a problem back when I used hostPath (as I could just directly copy data to and from the directory).

Are there any best practices when it comes to this? I can create a samba or ssh container to mount the share and connect that way, but it seems a bit clunky.

How does the community push data to mayaStor or cStor OpenEBS volumes?
