Azure Cloud Provider

To enable the Azure cloud provider, besides setting the name as azure, there are specific configuration options that must be set. Additionally, the Azure node name must also match the Kubernetes node name.

cloud_provider:
    name: azure
    azureCloudProvider:
      aadClientId: xxxxxxxxx
      aadClientSecret: xxxxxxxxx
      location: xxxxxxxxx
      resourceGroup: xxxxxxxxx
      subnetName: xxxxxxxxx
      subscriptionId: xxxxxxxxx
      vnetName: xxxxxxxxx
      tenantId: xxxxxxxxx
      securityGroupName: xxxxxxxxx

Overriding the hostname

Since the Azure node name must match the Kubernetes node name, you override the Kubernetes name on the node by setting the hostname_override for each node. If you do not set the hostname_override, the Kubernetes node name will be set as the address, which will cause the Azure cloud provider to fail.

nodes:
    - address: x.x.x.x
      hostname_override: azure-rke1
      user: ubuntu
      role:
        - controlplane
        - etcd
        - worker
