Azure Native v1: Installation & Configuration

To provision resources with the Pulumi Azure Native provider, you need to have Azure credentials. Your Azure credentials are never sent to Pulumi.com. Pulumi uses the Azure SDK and the credentials in your environment to authenticate requests from your computer to Azure.

Installation

The Azure Native provider is available as a package in all Pulumi languages:

• JavaScript/TypeScript: @pulumi/azure-native
• Python: pulumi-azure-native
• Go: github.com/pulumi/pulumi-azure-native/sdk/go/azure
• .NET: Pulumi.AzureNative
• Java: com.pulumi.azurenative

Authentication Methods

Pulumi can authenticate to Azure via several methods:

• Azure CLI
• Service Principal with a client secret or certificate
• OpenID Connect (OIDC)
• Managed Service Identity (MSI)

If you’re running the Pulumi CLI locally, in a developer scenario, we recommend using the Azure CLI. For team environments, particularly in CI, one of the other options is strongly recommended.

Authenticate using the CLI

The CLI instructions assume you’re using the Azure CLI (az).

Log in to the Azure CLI and Pulumi will automatically use your credentials:

$ az login
A web browser has been opened at https://login.microsoftonline.com/organizations/oauth2/v2.0/authorize. Please continue the login in the web browser. If no web browser is available or if the web browser fails to open, use device code flow with `az login --use-device-code`.

Do as instructed to log in. After completed, az login will return and you are ready to go.

The Azure CLI, and thus Pulumi, will use the Default Subscription by default. You can override the subscription by setting your subscription ID to the id output from az account list’s output:

$ az account list

Pick out the <id> from the list and run:

$ az account set --subscription=<id>

Authenticate with OpenID Connect (OIDC)

OIDC allows you to establish a trust relationship between Azure and another identity provider such as GitHub. Once established, your program can exchange a token issued by the identity provider (in this case, GitHub) for an Azure token. Your Pulumi program running in, for instance, GitHub Actions CI, can then access Azure, without storing any secrets in GitHub.

OIDC Azure Configuration

To configure the trust relationship in Azure, please refer to this guide. This needs to be set up only once.

Additionally, you may find the GitHub OIDC documentation helpful.

OIDC Pulumi Provider Configuration

To use OIDC, either set the Pulumi configuration useOidc via pulumi config set azure-native:useOidc true or set the environment variable ARM_USE_OIDC to “true”.

Next, supply the provider with an ID token and a URL to use for exchange. In GitHub, we don’t need to configure this since GitHub sets the relevant environment variables ACTIONS_ID_TOKEN_REQUEST_TOKEN and ACTIONS_ID_TOKEN_REQUEST_URL by default and the provider reads them. In other scenarios, set the Pulumi configuration azure-native:oidcRequestToken or environment variable ARM_OIDC_REQUEST_TOKEN for the token, and configuration azure-native:oidcRequestUrl or environment variable ARM_OIDC_REQUEST_URL for the URL.

Finally, configure the client and tenant IDs of your Azure Active Directory application. Refer to the above Azure documentation on how to retrieve the IDs, and set them via Pulumi config as azure-native:clientId and azure-native:tenantId or via environment variables as ARM_CLIENT_ID and ARM_TENANT_ID.

Authenticate using a Service Principal

A Service Principal is an application in Azure Active Directory with a client ID and a tenant ID, exactly like the one used in the OIDC scenario. In this scenario, instead of a pre-configured trust relationship, a client secret is used to authenticate with Azure.

Create your Service Principal and get your tokens

To use a Service Principal, you must first create one. If you already have one, skip this section.

You can create a Service Principal using the Azure CLI, using the Azure Cloud Shell, or using the Azure Portal.

After creating a Service Principal, you will obtain three important tokens:

• appId is the client ID
• tenant is the tenant ID
• password is the client secret

For example, a common Service Principal as displayed by the Azure CLI looks something like this:

{
  "appId": "WWWWWWWW-WWWW-WWWW-WWWW-WWWWWWWWWWWW",
  "displayName": "ServicePrincipalName",
  "name": "http://ServicePrincipalName",
  "password": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "tenant": "YYYYYYYY-YYYY-YYYY-YYYY-YYYYYYYYYYYY"
}

You also need to obtain a Subscription ID. To retrieve your current Subscription ID, you can use:

$ az account show --query id -o tsv

To list all available subscriptions, you can use:

$ az account list --query '[].{subscriptionName:name,subscriptionId:id}' -o tsv

Make tokens available to Pulumi

Once you have the Service Principal’s authorization tokens, choose one of the ways below to make them available to Pulumi:

Set configuration using pulumi config

Remember to pass --secret when setting clientSecret so that it is properly encrypted:

```bash
$ pulumi config set azure-native:clientId <clientID>
$ pulumi config set azure-native:clientSecret <clientSecret> --secret
$ pulumi config set azure-native:tenantId <tenantID>
$ pulumi config set azure-native:subscriptionId <subscriptionId>
# optional default location, otherwise set in code
$ pulumi config set azure-native:location <locationName>
```

Set configuration using environment variables

$ export ARM_CLIENT_ID=<YOUR_ARM_CLIENT_ID>
$ export ARM_CLIENT_SECRET=<YOUR_ARM_CLIENT_SECRET>
$ export ARM_TENANT_ID=<YOUR_ARM_TENANT_ID>
$ export ARM_SUBSCRIPTION_ID=<YOUR_ARM_SUBSCRIPTION_ID>
$ export ARM_LOCATION_NAME=<YOUR_ARM_LOCATION_NAME>

$ export ARM_CLIENT_ID=<YOUR_ARM_CLIENT_ID>
$ export ARM_CLIENT_SECRET=<YOUR_ARM_CLIENT_SECRET>
$ export ARM_TENANT_ID=<YOUR_ARM_TENANT_ID>
$ export ARM_SUBSCRIPTION_ID=<YOUR_ARM_SUBSCRIPTION_ID>
$ export ARM_LOCATION_NAME=<YOUR_ARM_LOCATION_NAME>

> $env:ARM_CLIENT_ID = "<YOUR_ARM_CLIENT_ID>"
> $env:ARM_CLIENT_SECRET = "<YOUR_ARM_CLIENT_SECRET>"
> $env:ARM_TENANT_ID = "<YOUR_ARM_TENANT_ID>"
> $env:ARM_SUBSCRIPTION_ID = "<YOUR_ARM_SUBSCRIPTION_ID>"
> $env:ARM_LOCATION_NAME = "<YOUR_ARM_LOCATION_NAME>"

Alternatively, you can use a certificate instead of a password as client secret. In this case, configure the provider as shown above except use clientCertPath/ARM_CLIENT_CERTIFICATE_PATH instead of clientSecret/ARM_CLIENT_SECRET.

Authenticate using Managed Service Identity (MSI)

When MSI is used for authentication, all configuration is done in Azure and we only need to tell the provider to use MSI. You can set the Pulumi configuration useMsi or the environment variable ARM_USE_MSI to “true”.

You can also configure a custom MSI endpoint, although this is not generally required. Do so via the msiEndpoint configuration or the ARM_MSI_ENDPOINT environment variable.

Configuration options

Use pulumi config set azure-native:<option> or pass options to the constructor of new azure-native.Provider.
