Azure Classic: Installation & Configuration

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


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

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.

Authenticating using the CLI will not work for Service Principal logins (e.g., az login --service-principal). For such cases, authenticate using the Service Principal method instead.

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 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.

If you’re using Government or China Clouds, you’ll need to configure the Azure CLI to work with that cloud. Do so by running az cloud set --name <Cloud>, where <Cloud> is one of AzureUSGovernment or AzureChinaCloud.

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: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:oidcRequestToken or environment variable ARM_OIDC_REQUEST_TOKEN for the token, and configuration azure: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:clientId and azure:tenantId or via environment variables as ARM_CLIENT_ID and ARM_TENANT_ID.

If you get the error “AADSTS70021: No matching federated identity record found for presented assertion”, this points to a configuration issue with the entity type and environment name described in the Azure documentation. Make sure they match your setup, e.g., the type “branch” and the correct branch name if CI runs against a fixed branch.

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

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

  "displayName": "ServicePrincipalName",
  "name": "http://ServicePrincipalName",

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:

$ pulumi config set azure:clientId <clientID>
$ pulumi config set azure:clientSecret <clientSecret> --secret
$ pulumi config set azure:tenantId <tenantID>
$ pulumi config set azure:subscriptionId <subscriptionId>
Set configuration using environment variables

Configuration options

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

environmentRequiredThe cloud environment to use. It can also be sourced from the ARM_ENVIRONMENT environment variable. Supported values are: public (default), usgovernment, china.
locationOptionalThe location to use. ResourceGroups will consult this property for a default location, if one was not supplied explicitly.
clientIdOptionalThe client ID to use. It can also be sourced from the ARM_CLIENT_ID environment variable.
clientSecretOptionalThe client secret to use. It can also be sourced from the ARM_CLIENT_SECRET environment variable.
msiEndpointOptionalThe REST endpoint to retrieve an MSI token from. Pulumi will attempt to discover this automatically but it can be specified manually here. It can also be sourced from the ARM_MSI_ENDPOINT environment variable.
oidcRequestTokenOptionalThe token to exchange for OIDC authentication. It can also be sourced from the ARM_OIDC_REQUEST_TOKEN environment variable.
oidcRequestUrlOptionalThe token exchange URL for OIDC authentication. It can also be sourced from the ARM_OIDC_REQUEST_URL environment variable.
skipCredentialsValidationOptionalPrevents the provider from validating the given credentials. When set to true, skip_provider_registration is assumed. It can also be sourced from the ARM_SKIP_CREDENTIALS_VALIDATION environment variable; defaults to false.
skipProviderRegistrationOptionalPrevents the provider from registering the ARM provider namespaces, this can be used if you don’t wish to give the Active Directory Application permission to register resource providers. It can also be sourced from the ARM_SKIP_PROVIDER_REGISTRATION environment variable; defaults to false.
subscriptionIdOptionalThe subscription ID to use. It can also be sourced from the ARM_SUBSCRIPTION_ID environment variable.
tenantIdOptionalThe tenant ID to use. It can also be sourced from the ARM_TENANT_ID environment variable.
useMsiOptionalSet to true to authenticate using managed service identity. It can also be sourced from the ARM_USE_MSI environment variable.
useOidcOptionalSet to true to authenticate using OIDC. It can also be sourced from the ARM_USE_OIDC environment variable.
