- To ensure most of the Azure Stack Edge features function in this disconnected mode, you'll activate your device via the Azure portal and deploy containerized and non-containerized workloads such as Kerberos, virtual machines (VMs), and IoT Edge use cases while you have an internet connection.

During offline use, you won't have access to the Azure portal to manage workloads; all management will be performed via operations local control plane operations. For a list of Azure endpoints that can't be reached during offline use, see [URL patterns for firewall rules](azure-stack-edge-gpu-system-requirements.md#url-patterns-for-firewall-rules).

| [Kubernetes](azure-stack-edge-gpu-kubernetes-overview.md) | Kubernetes deployments on a disconnected device have these differences:<ul><li>After you create your Kubernetes cluster, you can connect to and manage the cluster locally from your device using a native tool such as `kubectl`. With `kubectl`, a `kubeconfig` file allows the Kubernetes client to talk directly to the Kubernetes cluster without connecting to PowerShell interface of your device. Once you have the config file, you can direct the cluster using `kubectl` commands, without physical access to the cluster. For more information, see [Create and Manage a Kubernetes cluster on an Azure Stack Edge Pro GPU device](azure-stack-edge-gpu-create-kubernetes-cluster.md).</li><li>Azure Stack Edge has a local container registry - the Edge container registry - to host container images. While your device is disconnected, you'll manage the deployment of these images, pushing them to and deleting them from the Edge container registry over your local network. You won't have direct access to the Azure Container Registry in the cloud. For more information, see [Enable an Edge container registry on an Azure Stack Edge Pro GPU device](azure-stack-edge-gpu-edge-container-registry.md).</li><li>You can't monitor the Kubernetes cluster using Azure Monitor. Instead, use the local Kubernetes dashboard, available on the compute network. For more information, see [Monitor your Azure Stack Edge Pro device via the Kubernetes dashboard](azure-stack-edge-gpu-monitor-kubernetes-dashboard.md).</li></ul>For more information, see [Kubernetes on your Azure Stack Edge Pro GPU device](azure-stack-edge-gpu-kubernetes-overview.md). |
