Azure

Zuul can use Azure as a source for test nodes.

Before using the Azure driver, make sure you have created a service principal.

Two methods of authenticating the service principal are available: a shared secret or OIDC federation.

To use a shared secret: save the credential information in a JSON file. Follow the instructions at Azure CLI and use the --sdk-auth flag:

az ad sp create-for-rbac --name zuul --sdk-auth

There are two options for providing the information in this file to Zuul: place this file on the zuul-launcher and refer to it using <azure connection>.shared_credentials_file or extract the information in the file and provide it directly with the configuration options below.

To use OIDC federation, the JWT must be available in a file on the zuul-launcher (for example, by way of Kubernetes secret projection). Set the <azure connection>.subscription_id, <azure connection>.tenant_id, <azure connection>.client_id, and <azure connection>.federated_token_file fields.

You must also have created a network for Zuul to use. Be sure to enable IPv6 on the network if you plan to use it.

The Azure driver uses the “Standard” SKU for all public IP addresses. Standard IP addresses block all incoming traffic by default, therefore the use of a Network Security Group is required in order to allow incoming traffic. You will need to create one, add any required rules, and attach it to the subnet created above.

You may also need to register the Microsoft.Compute resource provider with your subscription.

The azure driver adds the following options to the provider and section configurations:

Connection Configuration

The supported options in zuul.conf connections are:

<azure connection>

<azure connection>.driver (required)

azure: The connection must set driver=azure for Azure connections.

<azure connection>.shared_credentials_file: A path to JSON file with shared access credentials. If this is supplied, no other credential settings need to be present.

<azure connection>.tenant_id: The Microsoft Entra tenant ID for the account. Required unless <azure connection>.shared_credentials_file is set.

<azure connection>.client_id: The Microsoft Entra client ID for the account. Required unless <azure connection>.shared_credentials_file is set.
