​Azure

Leverage Microsoft Azure services within Kestra data workflows.

Authentication

All tasks must be authenticated for the Azure Platform. Multiple authentication methods are supported:

1. Service Principal with Client Secret

You can set the following task properties:

• tenantId: Directory (tenant) ID of the Azure Active Directory instance.
• clientId: Application (client) ID of your service principal.
• clientSecret: Secret associated with your service principal.

This is a common method for server-to-server authentication and recommended for automation scenarios. This is best used with secrets to avoid exposing credentials in plain text.

2. Service Principal with Certificate

Alternatively, you can use a PEM certificate for authentication by specifying:

• tenantId
• clientId
• pemCertificate: PEM-formatted certificate content.

This method is preferred over client secrets when enhanced security and certificate lifecycle management are required.

3. Default Azure Credentials

If no client secret or certificate is defined, the DefaultAzureCredential chain will be used. This includes:

• Environment variables (AZURE_TENANT_ID, AZURE_CLIENT_ID, AZURE_CLIENT_SECRET, etc.).
• Managed identity for Azure resources (if the task is running on an Azure VM, App Service, etc.).
• Azure CLI logged-in user.
• Visual Studio Code or Azure Developer CLI credentials.

⚠️ In all cases, specifying tenantId is required.

4. SAS Token or Shared Key Authentication

Some Azure services support alternate authentication modes:

• Shared Key: use sharedKeyAccountName and sharedKeyAccountAccessKey for services like Azure Storage.
• SAS Token: use sasToken for temporary delegated access to resources.

These can also be stored as secrets.

Common Properties

• endpoint: Most tasks require an endpoint property pointing to the Azure service endpoint (e.g., Blob storage URL).
• scopes: Some tasks allow you to define custom scopes (defaults to https://management.azure.com/.default).

Example

id: azure_get_token
namespace: company.team

tasks: 
  - id: get_access_token
    type: io.kestra.plugin.azure.oauth.OauthAccessToken
    tenantId: "{{ secret('AZURE_TENANT_ID') }}"
    clientId: "{{ secret('AZURE_CLIENT_ID') }}"
    clientSecret: "{{ secret('AZURE_CLIENT_SECRET') }}"
