→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). Finally, it is probably good practice if other users of the dataset which are not the creator mount the volume readonly (by specifying "readOnly: true" after the mountPath in the pod's yaml).
=== Global dataset storage for large, static datasets ===
Every node has a link to a global repository "/raid/datasets" in its filesystem, which sits on very fast NVMe raid (1.9 GB/s read) and can be mounted read-only in every container as in the following example:
<syntaxhighlight lang="yaml">
todo
</syntaxhighlight>
Please see the page [[CCU:Global dataset storage|on global storage]] for a list of available datasets and the method to upload your own.
