Microsoft Azure Stack Hub is a hybrid cloud platform that enables you to provide Azure services from your own data center. Managing the Azure Stack Hub marketplace is a critical task for operators. Specifically, in a disconnected environment where the Azure Stack Hub is not connected to the internet, you need to pay extra attention to how to populate the marketplace to deliver services to your users. This article discusses how to populate Azure Stack Hub Marketplace in a disconnected environment which is a vital topic for the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam.
Understanding Azure Stack Hub Marketplace
Azure Stack Hub Marketplace is essentially a service catalog from where users can deploy the services they need. In the connected mode where Azure Stack Hub is connected to the internet, marketplace items can be directly downloaded from Azure and published to the Azure Stack Hub.
However, in a disconnected environment, the situation becomes complicated. You cannot directly download items from Azure, making it challenging to populate your Azure Stack Hub Marketplace.
Populating Marketplace in a Disconnected Environment
Despite these challenges, Microsoft provides ways to populate the marketplace in a disconnected environment. The two main methods for doing this are:
- Using a Connected Azure Stack Hub Instance: With this method, you use a connected Azure Stack Hub which downloads the marketplace items. The items are then exported to a storage account and finally imported to the disconnected Azure Stack Hub. Note that the connected and disconnected Azure Stack Hubs must have the same version.
- Using the Azure Marketplace Package Downloader Tool: Microsoft provides this tool to download Azure Stack Hub marketplace items directly from Azure to local storage. After downloading, the items can be manually imported into the disconnected Azure Stack Hub.
Using a Connected Azure Stack Hub Instance
Here are the steps to populate the marketplace using a connected Azure Stack Hub instance:
- Download the Marketplace Items: Log into the Azure Stack Hub admin portal of the connected instance and navigate to the marketplace management. Download the needed marketplace items.
- Export the Items to a storage account: You can execute a PowerShell script to export the downloaded items to a Blob storage in the connected Azure Stack Hub.
- Copy the Blob to Disconnected Environment: Using the Azure Storage Explorer, you can copy the Blob container to a portable storage device.
- Import the Marketplace Items to Disconnected Azure Stack Hub: Finally, you manually import the copied items to the marketplace of the disconnected Azure Stack Hub through the admin portal.
Using the Azure Marketplace Package Downloader Tool
The Azure Marketplace Package Downloader tool is hosted on GitHub. After you download and extract the tool, you can use a simple command-line interface to download the marketplace items, which can later be imported to the disconnected Azure Stack Hub.
Conclusion
Populating Azure Stack Hub marketplace in a disconnected environment could be tricky, but with a connected Azure Stack Hub instance or the Azure Marketplace Package Downloader tool, you can overcome the challenges. Understanding this process is essential for those preparing for the AZ-600 Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub exam. Be sure to explore the Azure Stack Hub documentation for more examples and a deeper understanding of the steps and the scripts required, as well as to find the GitHub link for the downloader tool.
