storageclass & pvc for daemonset

[Jerry Hwang]

Hello,

I deployed storageclass and pvc and then deployed daemonset (4 pods) to use it, however I noticed the pvc was only mounted by a pod, the other 3 pods were not able to use it.

Anyone has experienced it and found a way around to make sc/pvc available to all pods in daemonset?

Thanks,

J

Hi Jerry,

With a Daemonset, all instances share the same PVC, so you need to use some multi writer storage like NFS.

If you want each instance to get a different volume, then you can use Statefulset's volumeClaimTemplates.
