Tutorial / Cram Notes
Azure Resource Manager (ARM) provides a management layer that enables you to create, update, and delete resources in your Azure account. When working with Microsoft Azure Stack Hub, you interact with two different environments: the Azure Stack Hub itself and the Azure cloud. It is crucial to understand how to obtain and connect to ARM endpoints in both environments to manage resources effectively.
Connecting to ARM in Azure:
-
Obtain the ARM endpoint for Azure
Normally, the ARM endpoint for Azure is
https://management.azure.com/. This is the endpoint you use when you send requests to Azure services. -
Authenticate to Azure
To authenticate to Azure, you can use Azure Active Directory (Azure AD) by obtaining a token that then gets passed along in the HTTP header of your API calls.
Example using Azure CLI for authentication and getting a token:
az login
az account get-access-token -
Connect using PowerShell
To connect to Azure using PowerShell, you’ll need to install the Azure PowerShell module and use the
Connect-AzAccountcmdlet. This connects to your Azure subscription by providing a sign-in prompt for Azure credentials.Install-Module -Name Az -AllowClobber -Scope CurrentUser
Connect-AzAccount -
Connect using Azure SDKs
You can also use Azure SDKs in various programming languages (like .NET, Java, Python, and JavaScript) to interact with ARM. These SDKs generally take care of the authentication and connection details for you.
Connecting to ARM in Azure Stack Hub:
-
Obtain the ARM endpoint for Azure Stack Hub
The ARM endpoint for Azure Stack Hub differs from the Azure cloud and is specific to each Azure Stack Hub deployment. You can typically retrieve it from the Azure Stack Hub administrator or from the Azure Stack Hub portal.
Example ARM endpoint for Azure Stack Hub:
https://management.local.azurestack.external/ -
Authenticate to Azure Stack Hub
Similar to Azure, you authenticate using Azure AD or Active Directory Federation Services (AD FS) depending on the deployment. This process involves obtaining a token that you include in your API calls against ARM.
-
Connect using PowerShell
To manage Azure Stack Hub with PowerShell, you will need a specific module for Azure Stack Hub. Before connecting, ensure that you have the Azure Stack Hub compatible Azure PowerShell module installed.
Then use the
Add-AzEnvironmentcmdlet to add the Azure Stack Hub environment to your PowerShell session, andConnect-AzAccountto authenticate.Add-AzEnvironment -Name “AzureStackHub” -ArmEndpoint “https://management.local.azurestack.external”
Connect-AzAccount -Environment “AzureStackHub” -
Connect using Azure Stack Hub SDKs
For programmatic access, you can differentiate between Azure and Azure Stack Hub by using the appropriate API profiles. Since Azure Stack Hub may lag in feature updates behind Azure, you should use the appropriate version of SDKs that match your Azure Stack Hub version.
Comparison of Azure vs Azure Stack Hub:
| Feature | Azure | Azure Stack Hub |
|---|---|---|
| ARM Endpoint | https://management.azure.com/ |
Specific to deployment, e.g., https://management.local.azurestack.external/ |
| Authentication | Azure AD | Azure AD or AD FS |
| PowerShell Module | Az | Specific Azure Stack Hub version of Az |
| SDK Compatibility | Latest SDKs | Version-matched SDKs with appropriate API profiles |
| Feature Availability | All new features and services | Subset of Azure services, depends on version |
When working with ARM in either environment, you may need to tailor your scripts and applications to accommodate these differences. It’s also worth noting that Azure Stack Hub operators might have specific policies or configurations that could alter the endpoints or authentication methods. Always check with your Azure Stack Hub operator for the most up-to-date and applicable information for your deployment.
Overall, obtaining and connecting to ARM endpoints in Azure and Azure Stack Hub involves understanding the different endpoints, authentication mechanisms, and toolsets available for each environment. While their APIs are similar, there are crucial differences in usage and compatibility to navigate throughout your operations.
