I am also attempting to figure out how to enable

feature gate

on RKE2. I have looked at https://rancher.com/docs/rancher/v2.6/en/cluster-admin/editing-clusters/rke2-config-reference/ which leads to https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet/

--feature-gates <A list of 'key=true/false' pairs>

...

(DEPRECATED: This parameter should be set via the config file specified by the Kubelet's

--config

flag. See kubelet-config-file for more information.)

I have tried a few ways to add, but all the ways I would add to rke do not seem to be there. I used to be able to add via API. Wanting to add to test out linstor-csi

You will need to enable the following feature gates on both the kube-apiserver and all kubelets for this plugin to be operational:

CSINodeInfo=true

,

CSIDriverRegistry=true,VolumeSnapshotDataSource=true

. Please ensure that your version of Kubernetes is recent enough to enable these gates.

Other Doc: https://linbit.com/blog/linstor-csi-plugin-for-kubernetes/ Any know how to enable feature flags on RKE2 though Rancher?

Yeah it was a similar problem for me with trying to install the

AWS EBS CSI Driver

. I found this issue https://github.com/rancher/rke2/issues/3145 in the end I tried without the feature gates and the driver worked anyways. If you are on a test cluster you can attempt to install the CSI plugin without enabling those feature gates.

Yeah that is what I did, I found that the flags are all GA anyway lol
