→Global persistent volumes
Since anyone can mount global persistent volumes in the same namespace, they can and should be used to share datasets. The name of a PVC which contains a useful dataset should start with "dataset-" and be descriptive, so that it can easily be found by other users. Also, the root of the PVC should contain a README with informations about the dataset (at least the source and what exactly it is).
A note on mounting. Currently (will change in the near future), ceph volumes can be either mounted ReadWrite by a single pod only, or ReadOnly by multiple pods. Thus, the workflow for a static dataset is to create the PVC, then create a pod to write all the data to it, then delete this pod and mount it read only from now on (using ReadOnlyMany as access mode) so it can be used in multiple pods.
