Azure Stack HCI Arc Ressource Bridge was deleted by deploying Azure Kubernetes Service

Question

I built an Azure Stack HCI Lab, then connected to Arc and built the Arc Resource Bridge. After that I was able to successfully deploy VMs from the Azure Portal.

After that I built Azure Kubernetes Service via Admin Center. The operation deleted the resource bridge on the HCI cluster. Now the message appears when you click on Resource Bridge in the Admin Center.

"You cannot call a method on a null-valued expression."

What can I do? I want to test both scenarios.

Hi Robert,

VM Self Service is currently in preview and both AKS on HCI and VM Self Service use the same resource bridge. If you want to use AKS on HCI and VM Self service on the same stamp you have to install AKS first, and on top of that deploy VM self Service. Also you might want to consider using powershell instead of Admin Center. Admin Center is not ready yet to deploy these to features side by side.

Beware that you need to skip some steps of the VM Self service because you already configured it with the AKS on HCI deployment.

Update:

I changed the hci-infra.yaml file and changed the k8snodeippoolstart from 192.168.57.174 (used for AKS management) to 192.168.57.175 (free) and now the deployment works fine.

Is this a bug?

Hi @Robert ,

Have you referred this link - https://learn.microsoft.com/en-us/azure/azure-arc/resource-bridge/troubleshoot-resource-bridge ?

Hello, I've the same challenge. I've deployed AKS management cluster.

And try now deploy VM Self Service (from here https://learn.microsoft.com/en-us/azure-stack/hci/manage/troubleshoot-arc-enabled-vms#limitations-and-known-issues) and start here https://learn.microsoft.com/en-us/azure-stack/hci/manage/deploy-arc-resource-bridge-using-command-line#install-powershell-modules-and-update-extensions on step 4.

The script https://learn.microsoft.com/en-us/azure-stack/hci/manage/deploy-arc-resource-bridge-using-command-line#install-powershell-modules-and-update-extensions on step 3 stucked by this line "az arcappliance deploy hci --config-file $csv_path\ResourceBridge\hci-appliance.yaml --outfile $env:USERPROFILE.kube\config" and after few minutes a got a time out.

The script use the same IP as the management cluster

Is this correct?
