Answer 1

There are two options.

I. set

KUBELET_EXTRA_ARGS=--FLEXVOLUME_DIR_PATH=/var/lib/kubelet/volumeplugins

within the file

/etc/default/kubelet

And restart kubelete service

sudo systemctl restart kubelet

II. You can set kubelet parameters via a config file.

For example:

kind: KubeletConfiguration
apiVersion: kubelet.config.k8s.io/v1beta1
env:
- name: FLEXVOLUME_DIR_PATH
  value: "/var/lib/kubelet/volumeplugins"

Then, you just start the Kubelet with the --config flag set to the path of the Kubelet’s config file

sudo kubelet --config=/etc/default/kubelet/custom-conf.config
