Setting up the Azure Cloud Provider

When using the Azure cloud provider, you can leverage the following capabilities:

  • Load Balancers: Launches an Azure Load Balancer within a specific Network Security Group.

  • Persistent Volumes: Supports using Azure Blob disks and Azure Managed Disks with standard and premium storage accounts.

  • Network Storage: Support Azure Files via CIFS mounts.

The following account types are not supported for Azure Subscriptions:

  • Single tenant accounts (i.e. accounts with no subscriptions).
  • Multi-subscription accounts.

To set up the Azure cloud provider following credentials need to be configured:

  1. Set up the Azure Tenant ID
  2. Set up the Azure Client ID and Azure Client Secret
  3. Configure App Registration Permissions
  4. Set up Azure Network Security Group Name

1. Set up the Azure Tenant ID​

Visit Azure portal, login and go to Azure Active Directory and select Properties. Your Directory ID is your Tenant ID (tenantID).

If you want to use the Azure CLI, you can run the command az account show to get the information.

2. Set up the Azure Client ID and Azure Client Secret​

Visit Azure portal, login and follow the steps below to create an App Registration and the corresponding Azure Client ID (aadClientId) and Azure Client Secret (aadClientSecret).

  1. Select Azure Active Directory.
  2. Select App registrations.
  3. Select New application registration.
  4. Choose a Name, select Web app / API as Application Type and a Sign-on URL which can be anything in this case.
  5. Select Create.

In the App registrations view, you should see your created App registration. The value shown in the column APPLICATION ID is what you need to use as Azure Client ID.

The next step is to generate the Azure Client Secret:

  1. Open your created App registration.
  2. In the Settings view, open Keys.
  3. Enter a Key description, select an expiration time and select Save.
  4. The generated value shown in the column Value is what you need to use as Azure Client Secret. This value will only be shown once.

3. Configure App Registration Permissions​

The last thing you will need to do, is assign the appropriate permissions to your App registration.

  1. Go to More services, search for Subscriptions and open it.
  2. Open Access control (IAM).
  3. Select Add.
  4. For Role, select Contributor.
  5. For Select, select your created App registration name.
  6. Select Save.

4. Set up Azure Network Security Group Name​

A custom Azure Network Security Group (securityGroupName) is needed to allow Azure Load Balancers to work.

If you provision hosts using Rancher Machine Azure driver, you will need to edit them manually to assign them to this Network Security Group.

You should already assign custom hosts to this Network Security Group during provisioning.

Only hosts expected to be load balancer back ends need to be in this group.
