ReadWriteMany access mode possible alternatives?

[Mmoncadaisla]

Context

As we are exploring geonode-k8s project for our use case, deploying to Google Kubernetes Engine, we're able to see that it uses PVC ReadWriteMany accessMode, which in the particular case of GCP is not straightforward as it requires leveraging NFS.

In Google Cloud, we believe this implies either leveraging Filestore (which has a minimum of 1 TB of capacity) or else leveraging another NFS source (perhaps using MinIO or another provider like NetApp)

For what we've seen, although it is possible to maintain NFS for ReadWriteMany access mode support without depending on another service like Firestore, apparently this could add some complexity in the long term.

See also this SO post for reference.

Basically, the answer is "do everything you can to avoid ReadWriteMany, and use cloud-native services instead". The concepts of NFS don't really map well onto kubernetes, and you will save yourself a lot of trouble if you only use ReadWriteMany volumes after all else fails. For sharing files, using something like an object storage API (GCS or Amazon S3 or Openstack shift or MinIO or something along those lines) is a better idea in the long run

Question

Sorry in advance for the silly question 🙇🏼‍♂️ but is ReadWriteMany access mode compulsory for geonode-k8s to work? Do you happen to have any recommendations for GKE setup?
