Managing Secrets and Secure Access in Azure Applications

Managed identities for Azure resources provides Azure services with an automatically managed identity in Azure Active Directory (Azure AD).

This example demonstrates using a managed identity with Azure App Service to access Azure KeyVault, Azure Storage, and Azure SQL Database without passwords or secrets.

The application consists of several parts:

• An ASP.NET Application which reads data from a SQL Database and from a file in Blob Storage
• App Service which host the application. The application binaries are placed in Blob Storage, with Blob Url placed as a secret in Azure Key Vault
• App Service has a Managed Identity enabled
• The identify is granted access to the SQL Server, Blob Storage, and Key Vault
• No secret information is placed in App Service configuration: all access rights are derived from Active Directory

Running the App

1. Create a new stack:

   $ pulumi stack init dev
   

2. Login to Azure CLI (you will be prompted to do this during deployment if you forget this step):

   $ az login
   

3. Restore NPM dependencies:

   $ npm install
   

4. Build and publish the ASP.NET Core project:

   $ dotnet publish webapp
   

5. Set an appropriate Azure location like:

   $ pulumi config set azure:location westus
   

6. Run pulumi up to preview and deploy changes:

   $ pulumi up
   Previewing changes:
   ...
   
   Performing changes:
   ...
   info: 15 changes performed:
       + 15 resources created
   Update duration: 4m16s
   

7. Check the deployed website endpoint:

   $ pulumi stack output endpoint
   https://app129968b8.azurewebsites.net/
   $ curl "$(pulumi stack output endpoint)"
