ImageStore keeps copied package and provisioned packages.
Sequence of provision in Best Practice:
- Copy package to ImageStore with compress option
- Provision package
- Remove package in ImageStore
- Upgrade app/cluster
- Unprovision old version
When step 3 and 5 are missing, ImageStore accumulates files.
Symptom:
- The ImageStoreService (fabric:/System/ImageStoreService) could fill up disk.
- ImageStoreService replica may take long time in InBuild.
Option/Configuration for automatic cleanup:
How to configure cleaning up copied application package (automatic Step 3)
- Register-ServiceFabricApplicationType –ApplicationPackageCleanupPolicy Automatic
At step 2, Register (a.k.a. Provision), the application package is deleted after successfully registering the application type.
- <Section Name=”Management”>
<Parameter Name=”CleanupApplicationPackageOnProvisionSuccess” Value=”False” />
</Section>
This configuration enabled automatic cleanup of application package after successfully registering the application type.
How to configure cleaning up automatically unused application type (automatic Step 5)
<Section Name=”Management”>
<Parameter Name=”CleanupUnusedApplicationTypes” Value=”true” />
<Parameter Name=”PeriodicCleanupUnusedApplicationTypes” Value=”true” />
<Parameter Name=”TriggerAppTypeCleanupOnProvisionSuccess” Value=”true” />
<Parameter Name=”MaxUnusedAppTypeVersionsToKeep” Value=”3″ />
</Section>
Manual Cleanup:
When ImageStoreService must be cleaned up manually, you can follow this steps.
1. Delete copied packages
#Delete Content from Image Store
$content =
Get-ServiceFabricImageStoreContent -RemoteRelativePath “” -ImageStoreConnectionString fabric:ImageStore
foreach($folder in $content)
{
Write-Host Working on $folder.StoreRelativePath
if (($folder.StoreRelativePath -ne “Store”) -and ($folder.StoreRelativePath -ne “WindowsFabricStore”))
{
Write-Host Deleting $folder.StoreRelativePath
Remove-ServiceFabricApplicationPackage -ApplicationPackagePathInImageStore $folder.StoreRelativePath -ImageStoreConnectionString fabric:ImageStore
}
}
2. Unregister
Unregister-ServiceFabricApplicationType will remove application packages from image store as well as ImageCache on nodes (after a while).
Scenario1 : Seeing zombie application package in the store, which taking most of the disk space.
- Verify whether meta data for the older version is associated with ISS [ Get-SFImageStoreContent -remoterelativepath ‘StoreIberFabric.App.PortalComercial.Services.AgendaType’ verify whether older package type is in the list ]
- If the older file is not listed in the #1, you can rdp into each VM which hosting the ISS replica, and delete it manually
- If meta data is present in #1 output, please verify the version customer wanted to delete is already in the registry by running, ‘Get-ServiceFabricApplicationType’
- In the #3 output, If the application type is already there, please un provision by ‘Unregister-ServiceFabricApplicationType’
- If the #3 output application type detail is not present, you can run ‘ Remove-ServiceFabricApplicationPackage -ApplicationPackagePathInImageStore “StoreIberFabric.App.PortalComercial.Services.AgendaType<<package with version number>>

What a busy week it’s been in the world of Azure. Here are the news items the team is covering this week: Azure Stack HCI achieves general availability status, Azure Stack Edge supporting Kubernetes and Virtual Machines, GitHub Universe announcements, Azure Digital Twins now generally available, AKS pod identity offered via Azure AD in public preview, Azure Portal to drop IE11 support and the Microsoft Learn Module of the Week.
Azure Stack HCI achieves general availability status
Azure Stack HCI is Microsoft’s new subscription service for hyperconverged infrastructure and has now reached general availability. The service allows organizations to run virtual machines, containers, and select Azure services on-premises with management, billing, and support made available through the Azure cloud. Sarah Lean recently sat down with Microsoft Sr. Program Manager Matt McSpirit to discuss what Azure Stack HCI is, how you can use it within your environment and how it works with Windows, Linux, Kubernetes, Windows Admin Centre and Azure Arc.
Further details surrounding the Azure Stack HCI announcement can be found here: Starting a new era for Azure Stack HCI
GitHub Universe announcements
This week we saw GitHub host their annual conference GitHub Universe virtually. Normally this isn’t a conference IT Pros would pay attention to however, after listening to Sarah’s chat with Martin Woodward in Azure Unblogged – GitHub I paid a little more attention to it this year. And there were some cool announcements made!
The first one was that GitHub now has a dark mode, so if you are a fan of the dark mode across your applications and workstation you can turn it on for GitHub as well.
The second was an announcement was around Discussions within GitHub. This allows for your team and community to chat and work together within your project repository in a threaded format. You can mark questions are answered and over time use this as a knowledge base for the community. This feature is currently within Beta with a few open-source communities but will be available within other projects soon.
And the third announcement I want to highlight from GitHub Universe is GitHub Sponsors for companies. Individuals can already contribute money to help support open-source projects but with this new feature is companies can how do it without having to have individual procurement agreements with each open-source project. Now organizations can support those open-source projects they rely on or believe in as easy as adding the cost to their existing GitHub bill.
Further details can be found here: News from Universe 2020: Dark mode, GitHub Sponsors for companies, and more
Azure Stack Edge supporting Kubernetes and Virtual Machines
Azure Stack Edge can now manage Kubernetes environments and host Azure virtual machines to enable organizations to run VM based IoT, AI, and business applications on an Azure appliance at your location and or deploy containerized apps to the edge. Both offerings can be invoked via the Azure Portal. Do note that hosting Azure VMs on Azure Stack Edge is currently in preview.
Learn more on how to deploy Kubernetes apps from the cloud and or host your Azure virtual machines via IoT Edge here: Purpose-built hardware-as-a-service with Azure Stack Edge
Azure Digital Twins now generally available
The now generally available Azure Digital Twins offering breaks down silos within intelligent environments by fusing data from previously deployed devices and track both past and present events to simulate possibilities to help predict future events. As an example, Bentley Systems to develop a digital twin of its wind farms allowing operators to remotely monitor equipment performance and predict energy generation based on weather conditions. They used Azure Digital Twins to combine real-time and historical IoT, weather, and other operational data with physics and machine learning-based models to accurately predict production output for each turbine in the farm.
Checkout the Azure Digital Twins technical resources available here: Azure Digital Twins Documentation
AKS pod identity offered via Azure AD in public preview
AKS applications can now access cloud resources securely using Azure Active Directory (AAD). AAD simplifies access control by using it as an identity provider to any type of resource, including cluster, node, pod, etc. Identities need to be configured and bound to a resource. Once bound, containerized applications can then access the pod and any other resources in the cloud that use AAD as an identity provider.
Further details can be viewed here: Use Azure Active Directory pod-managed identities in Azure Kubernetes Service
Azure Portal to drop IE11 support
The Azure Portal web app will no longer support IE 11 as of March 31, 2021. Internet Explorer will continue to be supported by Microsoft as a component Windows and follows the Lifecycle Policy for the product on which it is installed. Internet Explorer mode use in Microsoft Edge will not extend IE 11 access to the Azure Portal beyond the date listed above.
Further details can be found here: Azure portal to end support for Internet Explorer 11 on March 31, 2021

Some of the users have a need to use service account for the connection – some other account than the logged in user. However because of SSO, this does not work – even after providing username in the credential pop up, it defaults back to the logged in user. The workarounds are documented here – Integrate with Office 365 Outlook – Azure Logic Apps | Microsoft Docs
Also as a workaround, it is possible to use HTTP action with AAD authentication to call the Graph API directly.
One of the members from dev team has found a hack to get it working. For a good number of users, it has worked. If you are are reluctant to provide contributor access to the service account, it may be worth trying.
Symptom:
A user logs into Azure portal as user1@xxx.com and he wants to create a logic app to send emails from logic app. He does not want the email to be sent from user1@xxx.com and instead he wants the email to be sent from user2@xxx.com. Logically he add the Outlook365 action to the logic app and then try to create the connection as user2@xxx.com. The problem is that even though he specifies user2@xxx.com on connection creation, the connection is still created with user1@xxx.com. This is because AAD has the SSO feature, where AAD notices he has already logged in as user1@xxx.com and it just uses that as the credential.
Solution:
This feature/ issue lies on the AAD SSO side – can check SSO article for more details What is Azure single sign-on (SSO)? | Microsoft Docs.
From the Logic Apps side dev member Dan has found a workaround below. It is a hacky workaround but works most of the times:
- Open IE Browser setting to disable Integrated Windows Authentication under Internet Options/Advanced tab. Close the browser and open it again to verify the setting is good.
