On GCE Kubernetes, how can I create volumes where multiple consumers can write?

Question

K8S Volume documentation mentions that only a single consumer can write to GCE PD. What can be used on GCE for volumes where multiple consumers can write simultaneously, for example when hosting a private Docker registry?

I see an sample for creating NFS volume on GCE. Is there a straightforward solution that I am missing?

Answer 1

I followed this solution to

1. create a GCE PD,
2. host a NFS server with GCE volume mounted at "/exports"
3. Use this NFS server as a volume

This was easy to do. One change I made was to add storage-class "" to the GCE PD PV and PVC file as I did not have a default storage class.
