1. How do I use Kubernetes CoreDNS with Azure Virtual Machines?

    C#

    To use CoreDNS with Azure Virtual Machines in a Kubernetes cluster, you firstly need to deploy Kubernetes in your Azure VM instances. Next, you will configure CoreDNS as the DNS service for your cluster.

    In this process, you will need to use azure-native.connectedvmwarevsphere.VirtualMachineInstance to create Azure Virtual Machines and kubernetes-coredns.CoreDNS to configure CoreDNS in your Kubernetes cluster.

    The program below demonstrates how you can accomplish that.

    For simplification, the program is divided into two main parts, the part where we create an Azure VM and the part where we create a CoreDNS resource.

    using Pulumi; using Pulumi.AzureNative.Resources; using Pulumi.AzureNative.Connectedvmwarevsphere; using Pulumi.Kubernetes; class MyStack : Stack { public MyStack() { // Create an Azure Resource Group (Assumption: Already Configured) var azureResourceGroup = new ResourceGroup("myResourceGroup"); // Create a Virtual Machine Instance with specified properties var virtualMachine = new VirtualMachineInstance("myVM", new VirtualMachineInstanceArgs { ResourceGroupName = azureResourceGroup.Name, Location = deploymentResourceGroup.Location, // Provide other instance properties here... }); // Create a CoreDNS configuration in Kubernetes. var myCoreDns = new Pulumi.Kubernetes.CoreDns.V1.Chart("coredns", new Pulumi.Kubernetes.CoreDns.V1.ChartArgs { Namespace = "coredns", // Provide other CoreDNS configuration here... }); } }

    When you run this program with the Pulumi CLI, Pulumi will perform the following steps:

    1. Create an Azure Resource Group.
    2. Create an Azure Virtual Machine Instance within that group.
    3. Configure CoreDNS that will run within your Kubernetes cluster.

    Remember to replace '...' in the second block with your actual CoreDNS configuration. You can see all of the configuration options for the CoreDNS Helm chart in the documentation.

    Please note that when you create Azure Virtual Machines, you will have to specify certain required properties like "osProfile", "networkProfile", and "storageProfile". You can find more details about these properties in the documentation.

    Also, ensure that Azure and Kubernetes are properly configured for your Pulumi project.
