Prerequisite

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

To 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 kuberenetes secret.
• If cluster identity is Managed Service Identity(MSI), make sure user assigned identity has Contributor role on node resource group

Install driver on a Kubernetes cluster

• install via kubectl on public Azure (please use helm for other cloud environments, e.g. Azure Stack)
• install via helm charts on public Azure and Azure Stack
