Per_container and Rancher NFS

Hi guys,

I’m currently trying to understand what the per_container setting does in combination with rancher NFS. Specifically, I want to deplay an Elasticsearch Cluster using the Rancher Template, but I do not really understand how and where and if volumes for the clusters will be persisted.

In particular, I’m wondering what this config does:

driver: rancher-nfs
per_container: true

Sadly, I can’t find a word on per_container in the docs.
