nfs-subdir-external-provisioner VS nfs-ganesha-server-and-external-provisioner

Using nfs-subdir-external-provisioner instead of csi-driver-nfs

I am trying to run sonarr inside my k3s cluster. Since I have multiple nodes, in order to keep data persistant I have been using a NAS and the Kubernetes NFS external provisioner as my Storage Class.

There's this, if you want your nfs storage available to pods as PVCs, with some limitations: https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner

NFS Provisioner

Depends on how much resiliency you need . Something like https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner works well for a lab or non-prod cluster. You could even use something like this in prod if you have access to highly reliably NFS mounts.

I first installed a NFS Server via this helm chart: https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner Eventually I deployed Longhorn cause I needed expandable volumes, which the first repo doesn't support. I guess for best performance you should go for a ceph cluster, but I'm not an expert.

I used the NFS provisioner for persistent volumes until I got the Ceph side up and running. I created a share on my NAS specifically for k8s. It worked very well and had the bonus of being just a regular file system that you could browse/edit easily (just place files in or edit config). I would agree with not moving plex into k8s. I right now just have a barebones 1 control 2 worker setup using k3s.

However, is it too difficult to create new pods/deployments etc on your own? I find it super easy to just create a PVC (via https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner ) and create a MySQL pod in a new namespace for every micro service I create.

This is what you need https://github.com/kubernetes-sigs/nfs-subdir-external-provisioner Point it to a folder and it will create subfolders for each PVC.

Now, for the purposes of this article, in case you don't have an NFS server available, we will use a simple NFS Server Provisioner, which we'll use only for example purposes. As mentioned before, using a managed solution from a cloud provider or a properly configured HA NFS server in your infrastructure is highly recommended. We'll install not the most up-to-date solution, but it should work for example purposes. We will follow the Quickstart found in the repo, mixed with this repo which does some small tweaks to make it work with K3d, which is summarized in the following commands run from the helm folder:

Some people just setup an NFS share. There's one that uses existing NFS and another that also provides NFS. This becomes a single point of failure though.

Conceptually to attach your storage to your pod, you have to go through 2 objects, the PVC that attaches to the PV, which itself must have a physical support, so the nfs mount on your nodes in hostpath, which is globally disgusting, it is better to inform the NFS server in your PV. Maybe I'm wrong but it seems clear to me. However, if you ask this kind of questions, you might be missing two or three things about K8. I advise you to read the documentation about PV, PVC, SC etc... Also NFS is not POSIX and by nature slow, which can cause inconsistencies in your data, but this is an extreme case. In a logic of automation you can use this: https://github.com/kubernetes-sigs/nfs-ganesha-server-and-external-provisioner Help yourself with this . https://www.linuxtechi.com/configure-nfs-persistent-volume-kubernetes/

I found something similar that seems to be a continuation of the nfs-server-provisioner- https://github.com/kubernetes-sigs/nfs-ganesha-server-and-external-provisioner
