Prerequisite

The driver depends on cloud provider config file (here is config example), config file path on different platforms:
- AKS, capz, aks-engine: /etc/kubernetes/azure.json
- Azure RedHat OpenShift: /etc/kubernetes/cloud.conf
<details> <summary>specify a different config file path via configmap</summary></br>create configmap "azure-cred-file" before driver starts up</br><pre>kubectl create configmap azure-cred-file --from-literal=path="/etc/kubernetes/cloud.conf" --from-literal=path-windows="C:\\k\\cloud.conf" -n kube-system</pre></details>
<details> <summary>edge zone support in cloud provider config</summary></br>`extendedLocationType` and `extendedLocationName` should be added into cloud provider config file, available values of `extendedLocationName` are `attatlanta1`, `attdallas1`, `attnewyork1`, `attdetroit1`</br><pre>```"extendedLocationType": "edgezone","extendedLocationName": "attatlanta1",```</pre></details>
Cloud provider config can also be specified via kubernetes secret, check details here
Make sure identity used by driver has Contributor role on node resource group
- When install open source driver on the cluster, ensure agentpool service principal or managed service identity is assigned to the Contributor role on the resource group used to store managed disks.
