1. Authentication for Azure Bot Services with Certificates.


    To authenticate Azure Bot Services with certificates, the process typically involves acquiring a certificate, then using it to configure the bot service to establish a secure communication channel. Azure Bot Service provides an identity when interacting with services such as Bot Framework Connector and Azure Active Directory.

    In your Pulumi program, you would follow these general steps:

    1. Acquire or create a certificate.
    2. Deploy a bot service on Azure using azure-native.botservice.Bot which allows you to configure authentication parameters.
    3. Set up the required properties for the bot including the Microsoft App ID and configuring the endpoint where the bot will be available.

    Below is a Python program using Pulumi to set up an Azure Bot Service and enable authentication using certificates. The program assumes you have the certificate details, specifically a certificate name, that you wish to use for the bot service. For simplicity, we use a managed identity (msaAppMSIResourceId), and reference the certificate from a given Key Vault.

    import pulumi import pulumi_azure_native as azure_native from pulumi_azure_native import botservice as bs # You should have a valid certificate uploaded to Azure Key Vault. # For this example, we assume the certificate details and Key Vault are already configured. # Replace these variables with the actual names and identifiers. certificate_name = "your-certificate-name" key_vault_id = "key-vault-id" app_id = "your-msa-app-id" bot_name = "your-bot-name" resource_group_name = "your-resource-group-name" # Create an Azure Bot Service with a Managed Identity and enable Client certificate-based authentication. bot_service = bs.Bot("botService", resource_name=bot_name, resource_group_name=resource_group_name, sku=bs.SkuDescriptionArgs(name=bs.SkuName.F0), # Choose a proper SKU. kind="Bot", # For a bot service, the kind should be "Bot" location="westus", # Replace with the location of your choice. properties=bs.BotPropertiesArgs( display_name=bot_name, endpoint="https://your-bot-name.azurewebsites.net/api/messages", # Replace with your endpoint. msa_app_id=app_id, msa_app_type="ManagedIdentity", # Managed Identity type for the bot. msa_app_msi_resource_id=key_vault_id, # Reference the Key Vault with the certificate. ) ) # Export the bot service name and endpoint URL. pulumi.export("bot_service_name", bot_service.name) pulumi.export("bot_service_endpoint", bot_service.properties.endpoint)

    This program creates an Azure Bot Service instance. The bs.BotPropertiesArgs class is used to configure the properties specific to the bot service, such as the display name, endpoint, and Microsoft App ID.

    The msa_app_msi_resource_id is used to refer to your Azure Key Vault where the certificate is stored. The certificate is then used to authenticate the managed identity associated with the Bot Service.

    Remember to replace placeholder values such as your-certificate-name, key-vault-id, your-msa-app-id, your-bot-name, and your-resource-group-name with actual values that you have setup in your Azure account.

    This program doesn't include the process of creating the certificate or the Azure Key Vault as those are outside the scope of this task and typically require manual steps or different permissions. You need to ensure that the certificate is stored securely in the Azure Key Vault and the bot service has the appropriate permissions (access policies) set to read from the Key Vault.

    After deploying this stack with pulumi up, you should have a Bot Service configured to authenticate via a client certificate obtained from Azure Key Vault. The pulumi.export statements will output the bot service name and the endpoint URL to the Pulumi service, so you can easily retrieve them after deployment.
