nfs-subdir-external-provisioner VS helmfile

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.

What we’re going to install into the newly created AKS cluster is located in the helm directory. The descriptive Helmfile approach enables us to define applications and their settings in the helmfile.yaml file.

Is there any alternative to https://github.com/roboll/helmfile you are currently using in your company.

Interesting, I have approached this problem using Helmfile (https://github.com/roboll/helmfile) to define a “platform release package.”

To make managing the Helm deployments a little easier I used helmfile (https://github.com/roboll/helmfile).

But in general it's always easier to keep things quite separated. Meaning in separate helm releases. If you want to be able to manage things "together" at will, then you can use helmfile ( https://github.com/roboll/helmfile )

I agree; helm is too declarative.

Whenever I can, I use helmfile[0] for storing variables for helm since it does add a declarative layer on top of helm.

I went through the Helmfile repo Readme to figure out the difference between helmfile sync and helmfile apply. It seems like unlike the apply command, the sync command doesn't do a diff and helm upgrades the hell out of all releases 😃. But from the word sync, you'd expect the command to apply those releases that have been changed. There is also mention of the potential application of helmfile apply to periodically syncing of releases. Why not use helmfile sync for this purpose? Overall, the difference didn't become crystal clear, and I though there could probably be more to it. So, I'm asking.

helmfile is something i’ve used in the past for this https://github.com/roboll/helmfile

I always felt like dependencies in helm are for very simple non-coupled packages. I many times use Helmfile (https://github.com/roboll/helmfile) to manage dependencies instead of banging my head with vanilla Helm.

Once you do that, learn to create dynamic helm charts that use go templating and conditionals: https://github.com/roboll/helmfile
