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

follow guide here

Prerequisite

  • The driver 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
    • When installing side-by-side with an earlier version of the driver on an AKS cluster, ensure the agentpool service principal or managed service identity is assigned to the Contributor role on the resource groups used to store managed disks.
  • Set up CSI driver on Azure RedHat OpenShift(ARO)

Install driver on a Kubernetes cluster

  • install via kubectl on public Azure (please use helm for Azure Stack, RedHat/CentOS)
  • install via helm charts on public Azure, Azure Stack, RedHat/CentOS
