1. Deploy the cosi-driver-nutanix helm chart on Azure Kubernetes Service (AKS)


    To deploy the cosi-driver-nutanix Helm chart on Azure Kubernetes Service (AKS), you will need to perform several steps, including setting up an AKS cluster, installing Helm on your local machine or inside your CI/CD system, and then using Helm to deploy the specified chart.

    We'll start by using Pulumi to provision an AKS cluster. Once the AKS cluster is up and running, we'll configure kubectl to connect to our new Kubernetes cluster. After this, we'll install the Helm CLI and use it to deploy the cosi-driver-nutanix Helm chart to our AKS cluster.

    Let's begin by writing a Pulumi program in TypeScript to create the necessary infrastructure.

    Before you run the Pulumi program, you must ensure that you have the Azure CLI installed and authenticated with your Azure account. Also, ensure that you have Pulumi CLI installed and configured.

    Here is the Pulumi program that sets up an AKS cluster:

    import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Create an Azure Resource Group const resourceGroup = new azure.core.ResourceGroup("aksResourceGroup"); // Create an Azure AD service principal for the Kubernetes cluster. const adApp = new azuread.Application("aks"); const adSp = new azuread.ServicePrincipal("aksSp", { applicationId: adApp.applicationId }); const adSpPassword = new azuread.ServicePrincipalPassword("aksSpPassword", { servicePrincipalId: adSp.id, endDate: "2099-01-01T00:00:00Z", }); // Create a virtual network for the AKS cluster. const vnet = new azure.network.VirtualNetwork("aksVnet", { resourceGroupName: resourceGroup.name, addressSpaces: [""], }); // Create a subnet for the AKS cluster. const subnet = new azure.network.Subnet("aksSubnet", { resourceGroupName: resourceGroup.name, virtualNetworkName: vnet.name, addressPrefix: "", }); // Now let's create the AKS cluster. const cluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, defaultNodePool: { name: "akspool", nodeCount: 2, vmSize: "Standard_DS2_v2", // Additional properties can be added as needed. }, dnsPrefix: `${pulumi.getStack()}-kube`, linuxProfile: { adminUsername: "aksuser", sshKey: { keyData: "ssh-rsa AAAAB3NzaC1yc2...key...", // replace with your real SSH public key }, }, servicePrincipal: { clientId: adApp.applicationId, clientSecret: adSpPassword.value, }, networkProfile: { networkPlugin: "kubenet", serviceCidr: "", dnsServiceIp: "", dockerBridgeCidr: "", }, }); // Export the kubeconfig to access the Kubernetes cluster. export const kubeConfig = cluster.kubeConfigRaw; // Use the pulumi/kubernetes provider to connect to the new AKS cluster. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeConfigRaw, }); // Here you would typically use `k8s.helm.v3.Chart`, `k8s.yaml.ConfigFile`, or other resources // to deploy applications to your cluster, including the `cosi-driver-nutanix` Helm chart.

    This program sets up an AKS cluster with a new Azure resource group, a service principal for authenticating with the Kubernetes cluster, and a virtual network with a subnet. The default node pool is set up with 2 virtual machines of size Standard_DS2_v2.

    After deploying the AKS cluster with Pulumi, you will have the kubeconfig output, which you can use to set up kubectl. You should replace the SSH key in linuxProfile with your own SSH public key.

    Next, we'll install Helm to your local machine. Visit the Helm releases page and follow the installation instructions specific to your operating system.

    Once Helm is installed, you can add repositories and install charts with commands like these:

    helm repo add nutanix https://nutanix.github.io/helm/ helm install my-cosi-driver nutanix/cosi-driver-nutanix --version <chart_version>

    Remember to replace <chart_version> with the version of the chart you wish to deploy.

    To deploy this Helm chart through Pulumi directly into AKS, you'd use the Kubernetes provider like shown in the commented section of the Pulumi program above. However, at the time of writing this response, the cosi-driver-nutanix Helm chart information isn't directly available through Pulumi, and you would need to use the Helm CLI to deploy this chart.

    Remember to configure kubectl to connect to your AKS cluster (by setting the KUBECONFIG environment variable or by using kubectl config commands) before running Helm commands. The kubeConfig exported by Pulumi can help set up kubectl.
