Support for storage on BSD/FreeNAS

Open platten opened this issue 4 years ago • 3 comments

Hello,

It would be great to be able to install zfs-localpv as part of a FreeNAS plugin, and have it provision/manage storage for Kubernetes cluster. It would be so much cleaner than using the iSCSI https://github.com/travisghansen/freenas-iscsi-provisioner or NFS https://github.com/nmaupu/freenas-provisioner solutions out there.

Thanks, Paul

@platten, thank you for suggesting this! It would be great to add it.

Could you please explain the use case a little more? How do you foresee using FreeNAS with Kubernetes? For instance: (a) Will FreeNAS be installed within K8s cluster, on the Kubernetes worker node (or) (b) Use it as Out of cluster mode.

Hello Kiran, I would see FreeNAS sitting outside of K8s and providing storage services for the K8s cluster (with a control plane/API running on K8s to request provisioning from FreeNAS and connect the storage to the pods).

If FreeNAS is running outside of the cluster, the Kubernetes worker node will need to access the storage over the network. It has to be either NFS or iSCSI or any other protocol that FreeNAS supports.

  • control plane (CSI driver) will run on K8s - manage the provisioning of volume.
  • node component ( CSI driver) also running on K8s - will have to attach/detach the volume using either NFS or iSCSI.

(what am I missing?)
