Install CSI driver with Helm 3

Prerequisites

• install Helm

Tips

• run smb-controller on control plane node: --set controller.runOnControlPlane=true
• Microk8s based kubernetes recommended settings:
  • --set linux.dnsPolicy=ClusterFirstWithHostNet with --set controller.dnsPolicy=ClusterFirstWithHostNet - external smb server cannot be found based on Default dns.
  • --set linux.kubelet="/var/snap/microk8s/common/var/lib/kubelet" - sets correct path to microk8s kubelet even though a user has a folder link to it.

install a specific version

helm repo add csi-driver-smb https://raw.githubusercontent.com/kubernetes-csi/csi-driver-smb/master/charts
helm install csi-driver-smb csi-driver-smb/csi-driver-smb --namespace kube-system --version v1.10.0

install driver with customized driver name, deployment name

only supported from v1.2.0+

• following example would install a driver with name smb2

helm install csi-driver-smb2 csi-driver-smb/csi-driver-smb --namespace kube-system --set driver.name="smb2.csi.k8s.io" --set controller.name="csi-smb2-controller" --set rbac.name=smb2 --set serviceAccount.controller=csi-smb2-controller-sa --set serviceAccount.node=csi-smb2-node-sa --set node.name=csi-smb2-node --set node.livenessProbe.healthPort=39643

search for all available chart versions

helm search repo -l csi-driver-smb

uninstall CSI driver

helm uninstall csi-driver-smb -n kube-system
