From 746ff37c26277159584e2ad9b01b55a8f70fbd71 Mon Sep 17 00:00:00 2001 From: PatrikBuhr Date: Fri, 30 Apr 2021 15:12:51 +0200 Subject: [PMS] Persistent storage of policies and type definitions Improvements: - Using common metadata for the PV and the PVC. - Changed the deployment to a stateful set. Even Deployments with one replica using ReadWriteOnce volume are not recommended. This is because the default Deployment strategy creates a second Pod before bringing down the first Pod on a recreate. The Deployment may fail in deadlock as the second Pod can't start because the ReadWriteOnce volume is already in use, and the first Pod won't be removed because the second Pod has not yet started. Instead, use a StatefulSet with ReadWriteOnce volumes.
