Kubernetes persistant volumes

Hello,

We have pool of persistent volumes (PV's) in kubernetes and we want to use
PV's as ignite persistence storage. '

Since there are different volumes are getting used, how does ignite
recognize the individual volumes?

Need installation instructions to support this feature.

Thanks,
-gokul

Hi Gokul,

Try to assign specific PV to specific Ignite pods by having several
different Kubernetes configuration files.

thanks Stephen.  If i understand it correctly, this deployment uses single
PV for ignite persistence.  If we have pool of PV's, how to make ignite
persistence. How to share these pv's among ignite nodes?.

The general recommendation is to use stateful sets: https://www.gridgain.com/docs/latest/installation-guide/kubernetes/openshift-deployment
