You can install IoT Edge on Kubernetes using KubeVirt technology. KubeVirt is an open-source project from the Cloud Native Computing Foundation (CNCF) that provides a Kubernetes virtualization API and runtime to define and manage virtual machines.
| Note | Description |
|---|---|
| 1 | Install KubeVirt custom resource definitions (CRDs) into the Kubernetes cluster. Like the Kubernetes cluster, management and updates to KubeVirt components are outside the purview of IoT Edge. |
| 2 | A KubeVirt VirtualMachine custom resource is used to define a Virtual Machine with required resources and base operating system. A running instance of this resouce is created in a Kubernetes Pod using KVM and QEMU technologies. If your Kubernetes node itself is a Virtual Machine, you'll need to enable Nested Virtualization to use KubeVirt. |
| 3 | The environment inside the QEMU container is just like an OS environment. IoT Edge and its dependencies (like the Docker container engine) can be setup using standard installation instructions or a cloud-init script. |
A functional sample for running IoT Edge on Azure Kubernetes Service (AKS) with KubeVirt is available at https://aka.ms/iotedge-kubevirt.
