• Available driver version: v0.5.0 or above

This driver also supports reading the cloud config from Kubernetes secrets. The secret is a serialized version of azure.json file with key cloud-config. The secret should be put in kube-system namespace and its name should be azure-cloud-provider.

How to convert cloud config to a Kubernetes secret

1. create azure.json file and fill in all necessary fields, refer to Cloud provider config, and here is an example

2. serialize azure.json by following command:

cat azure.json | base64 | awk '{printf $0}'; echo

3. create a secret file(azure-cloud-provider.yaml) with following values and fill in cloud-config value produced in step#2

apiVersion: v1
data:
  cloud-config: [fill-in-here]
kind: Secret
metadata:
  name: azure-cloud-provider
  namespace: kube-system
type: Opaque

4. Create a azure-cloud-provider secret in k8s cluster

kubectl create -f azure-cloud-provider.yaml
