Topics:

• OpenSearch
• Persistent Volumes

Notes:

This project is in support of WE4.2.6 - Deploy OpenSearch capabilities for discrete product features on the Data Platform.

We expect it to be deployed only to the dse-k8s clusters, where persistent volume support already exists.

Decision: pass, with some modifications.

Reasoning: The chart can be used securely in the WMF environment, so long as we remove a few overly-permissive settings (see the discussion on this CR for more context).
