Driver parameters

Please refer to driver parameters

Set up CSI driver on AKS cluster (only for AKS users)

follow guide here

Prerequisite

Option#1: Provide cloud provider config with Azure credentials

• This option depends on cloud provider config file, usually it's /etc/kubernetes/azure.json on agent nodes deployed by AKS or aks-engine, here is azure.json example.

  specify a different cloud provider config file

  
  create azure-cred-file configmap before driver installation, e.g. for OpenShift, it's /etc/kubernetes/cloud.conf (make sure config file path is in the volumeMounts.mountPath)
  

  kubectl create configmap azure-cred-file --from-literal=path="/etc/kubernetes/cloud.conf" --from-literal=path-windows="C:\\k\\cloud.conf" -n kube-system

• This driver also supports read cloud config from kubernetes secret as first priority

• Make sure identity used by driver has Contributor role on node resource group and vnet resource group

• How to set up CSI driver on Azure RedHat OpenShift(ARO)

Option#2: Bring your own storage account (only for SMB protocol)

This option does not depend on cloud provider config file, supports cross subscription and on-premise cluster scenario. Refer to detailed steps.

Install driver on a Kubernetes cluster

• install by kubectl (please use helm for RedHat/CentOS)
• install by helm charts (supports RedHat/CentOS)
