democratic-csi VS kadalu

The interface software regarding is not a worry of mine, as democratic-csi does the storage management for me, thus the compatibility it is not limited to the application using the storage per se, as this is handled by Kubernete's CSI drivers, being application-agnostic when utilizing the storage provided.My main worry is not latency, but rather RAM

in k3s, i'm using https://github.com/democratic-csi/democratic-csi (was using iSCSI before, now everything is NFS)

Have you checked this out? GitHub democratic-csi I have yet to test this in my @home K8s cluster. It supports iSCSI volume management for FreeNAS, Synology and other CSI backends.

If you ever migrate from docker up to kubernetes, then take a look into democratic-csi. For a modest homelab, it is a valid option (said from somebody who manages a small homelab and plays around with kubernetes).

For persistent storage have you looked into using TrueNAS with a CSI provider with your container orchestrator? I'm assuming your orchestrator is Nomad or Kubernetes.

Yes, Rancher does support FreeNAS, TrueNAS. and Scale using the storage class provider https://github.com/democratic-csi/democratic-csi It's important to remember Rancher is the server. And in this case, you need to ask the question does the k8s cluster that Rancher is managing support this storage class provider? If you are using RKE the answer is Yes.

I use https://github.com/democratic-csi/democratic-csi to mount nfs/iscsi shares (and manage the shares) from my SAN (truenas box).

iSCSI with democratic-csi (https://github.com/democratic-csi/democratic-csi) works great for me on truenas. I use iSCSI for any PVs that don't need to be shared and NFS for anything I'd like to share between different pods (like movies, music).

Storage - democratic-csi looked the most promising, it has worked well so far. I am using zfs-generic-iscsi against an Ubuntu 20.04 storage server. I also tried zfs-generic-nfs and it worked successfully with the caveat of having to deal with NFS file permissions.

https://github.com/kadalu/kadalu/ is mentioned in https://github.com/kubernetes/kubernetes/issues/100897

Right now im just mounting NFS to my worker nodes and then using docker volumes for storage, i have seen this https://github.com/kadalu/kadalu but i havent gotten around to trying it

For gluster you can check out https://github.com/kadalu/kadalu. I tried but ultimately went back to host-mounted gluster: for some reason they chose to implement their controller in Python and it uses a lot of memory. Too much for my Pi’s.

Kadalu Storage is an opinionated distribution of GlusterFS. Kadalu Storage is light weight solution based on GlusterFs, that eliminates may layers(Glusterd) and integrate directly with Kubernetes APIs.

Kadalu, a distributed persistent storage solution like longhorn, is available on ARM: https://github.com/kadalu/kadalu
