Lifecycle Management
Upon uninstallation of an XRd instance, if you had configured persistence, a persistent volume claim (PVC) remains. To fully eliminate the XRd instance, you must delete the PVC manually.
To enable support upgrade flows, bring down the worker node, uninstall the XRd deployment while retaining the PVC to allow persistence over upgrades, reinstall and reinstate with new settings.
You can use the standard Helm upgrade path if no worker node modifications are needed. The worker node can remain operational during the upgrade. Kubernetes must accept the resource changes that ensue.
Testing in the lab may be necessary to determine if an upgrade is compatible because not all circumstances are considered. Most configuration upgrades, including images, base configurations, and interfaces, are expected to work with this method.
