Error occurred in Google Cloud (GKE) on Kuburnets install

[cmj717_GTP]

Hi, experts.

We are continuing to try to install Installation Qlik Sense Enterprise on Kubernets.

After all failures in the local vm environment or Oracle Cloud (OKE)
I found the Google Cloud (GKE) installation guide on Qlik Support.

I installed it from Google Cloud (GKE) using the URL below.

https://support.qlik.com/articles/000082465

We followed the guide, but the installation failed.

Reviewing installation failure
I checked the pvc event below.
ProvisioningFailed :  failed to provision volume with StorageClass "nfs-dynamic": error getting NFS server IP for volume: service SERVICE_NAME=nfs-nfs-server-provisioner is not valid; check that it has for ports map[{2049 TCP}:true {20048 TCP}:true {111 UDP}:true {111 TCP}:true] exactly one endpoint, this pod's IP POD_IP=10.4.0.9

If anyone knows the cause, please help me.

2) pv

@cmj717_GTP, from the link below, looks like you can get this when the ProvisionerName is set empty. But it should self generate...
