Microk8s uses a non-standard Kubelet state directory.
Installing listener-operator on Microk8s requires the argument
`--set kubeletDir=/var/snap/microk8s/common/var/lib/kubelet` to be added to the `helm install` command.

=== HUAWEI cloud

In some cases HUAWEI cloud has the kubelet directory located at `/mnt/paas/kubernetes/kubelet`, resulting in the following error:

`failed to publish volume error=status: Unavailable, message: "failed to create secret parent dir /mnt/paas/kubernetes/kubelet/pods/<POD_ID>/volumes/kubernetes.io~csi/pvc-<PVC_ID>/mount: No such file or directory (os error 2)"`

In case you are encountering the mentioned error (or listener-operator does not work on your HUAWEI cloud at all), you need to add the argument `--set kubeletDir=/mnt/paas/kubernetes/kubelet` to the `helm install` command.

=== IBM cloud

In case you are encountering the mentioned error (or listener-operator does not work on your IBM cloud at all), you need to add the argument `--set kubeletDir=/var/data/kubelet` to the `helm install` command.

=== VMware Tanzu
