How to kubernetes on xcp-ng (csi?)
-
If you specify us exactly what do you need to access, we can help you to make a CSI provider for XO API. We need to know which "commands" do you need. It seems relatively simple if I understand correctly: create a virtual disk, give its size, then remove it or expand it. Right?

@olivierlambert here's a page at the kubernetes site talking about storage providers: https://kubernetes.io/docs/concepts/storage/storage-classes/
Kubernetes has a few built in but they can also be external providers, which I've used for nfs and cifs. I believe kubernetes speaks csi to interact with the providers.
There may already be something... in my first post I mentioned someone created one for xcp-ng a couple years ago. Tried it out and it no longer works. Hoping it may have evolved and become more integrated somehow... and someone might know who sees this post.
Getting something put together and added to kubernetes as a built in solution would be nice... could draw in business as xcp-ng would shine as a platform for kubernetes... but I'm ok with using a solution I have to install.
-
@olivierlambert ok, I can see about putting something together. First though, going to wait a bit with my fingers crossed to see if someone might already have something.

To help k8s integration with XCP-ng/XO we already have plans to write a Node driver for Rancher.
But if CSI driver is simple to make, why not. But having a real specification will be more helpful than telling us to learn it in the first place

Update in case someone comes across this posting looking for the same answer. I needed a solution sooner than later and am so far thrilled with truenas core, a free solution if you've got a box to spare. It has several providers which can be used with kubernetes.
Moved my large drives from my two xcp-ng servers over to truenas.
Working solution: Kubernetes nodes as vms on xcp-ng, Kubernetes storage provisioner hosted via truenas core.

OMG that would be amazing!

Stay tuned but work started
-
@olivierlambert Do you have any news regarding xo CSI storage provider for kubernetes?
-
Not yet sadly, the persons tasked to do it aren't giving any news since a while. Internally, we are working on our Project Pyrgos to help deploy easily k8s clusters.
-
@olivierlambert Thanks for the prompt reply! Fingers crossed for the Project Pyrgos!
-
@olivierlambert any update to this and the pyrgos project?
-
Yes, June's release came with new features, like selecting the Kubernetes version. We got multi control planes before, static IPs and such.
Take a look at our blog posts to see what's going on, there's not a new feature per month (yet) but it's moving forward
-
@olivierlambert ok seen there was another blog post about it here https://xen-orchestra.com/blog/xen-orchestra-5-84/
ok cool, thanks
-
Next steps take a bit more time because it's about storing the cluster key safely to be able (then) to use XO to make basic queries on it (like current version and such), which is the first step to prepare the automated node upgrade/replacement
