Use API version profiles with Go in Azure Stack Hub

Go and version profiles

A profile is a combination of different resource types with different versions from different services. Using a profile helps you mix and match between different resource types. Profiles can provide the following benefits:

• Stability for your app by locking to specific API versions.
• Compatibility for your app with Azure Stack Hub and regional Azure datacenters.

In the Go SDK, profiles are available under the profiles path. Profile version numbers are labeled in the YYYY-MM-DD format. For example, Azure Stack Hub API profile version 2020-09-01 isfor Azure Stack Hub versions 2102 or later. To import a given service from a profile, import its corresponding module from the profile. For example, to import Compute service from 2020-09-01 profile, use the following code:

import "github.com/Azure/azure-sdk-for-go/profiles/2020-09-01/compute/mgmt/compute"

Install the Azure SDK for Go

1. Install Git. See Getting Started - Installing Git.
2. Install Go. API profiles for Azure require Go version 1.9 or newer. See Go programming language.

Profiles

To use a different SDK profile or version, substitute the date in an import statement such as github.com/Azure/azure-sdk-for-go/profiles/<date>/storage/mgmt/storage. For example, for the 2008 version, the profile is 2019-03-01, and the string becomes github.com/Azure/azure-sdk-for-go/profiles/2019-03-01/storage/mgmt/storage. Note that sometimes the SDK team changes the name of the packages, so simply replacing the date of a string with a different date might not work. See the following table for association of profiles and Azure Stack versions.

For more information about Azure Stack Hub and API profiles, see the Summary of API profiles.

See Go SDK profiles.

Subscription

If you do not already have a subscription, create a subscription and save the subscription ID to be used later. For information about how to create a subscription, see this document.

Service principal

A service principal and its associated environment information should be created and saved somewhere. Service principal with owner role is recommended, but depending on the sample, a contributor role may suffice. Refer to the README in the sample repository for the required values. You may read these values in any format supported by the SDK language such as from a JSON file (which our samples use). Depending on the sample being run, not all of these values may be used. See the sample repository for updated sample code or further information.

Tenant ID

To find the directory or tenant ID for your Azure Stack Hub, follow the instructions in this article.

Register resource providers

Register required resource providers by following this document. These resource providers will be required depending on the samples you want to run. For example, if you want to run a VM sample, the Microsoft.Compute resource provider registration is required.

Azure Stack resource manager endpoint

Azure Resource Manager (ARM) is a management framework that enables administrators to deploy, manage, and monitor Azure resources. Azure Resource Manager can handle these tasks as a group, rather than individually, in a single operation. You can get the metadata info from the Resource Manager endpoint. The endpoint returns a JSON file with the info required to run your code.

• The ResourceManagerEndpointUrl in the Azure Stack Development Kit (ASDK) is: https://management.local.azurestack.external/.
• The ResourceManagerEndpointUrl in integrated systems is: https://management.region.<fqdn>/, where <fqdn> is your fully qualified domain name.
• To retrieve the metadata required: <ResourceManagerUrl>/metadata/endpoints?api-version=1.0. For available API versions, see Azure rest API specifications. E.g., in 2020-09-01 profile version, you can change the api-version to 2019-10-01 for resource provider microsoft.resources.

Sample JSON:

{
   "galleryEndpoint": "https://portal.local.azurestack.external:30015/",
   "graphEndpoint": "https://graph.windows.net/",
   "portal Endpoint": "https://portal.local.azurestack.external/",
   "authentication": 
      {
         "loginEndpoint": "https://login.windows.net/",
         "audiences": ["https://management.yourtenant.onmicrosoft.com/3cc5febd-e4b7-4a85-a2ed-1d730e2f5928"]
      }
}

Samples

See the sample repository for update-to-date sample code. The root README.md describes general requirements, and each sub-directory contains a specific sample with its own README.md on how to run that sample.
