1. Deploy the snmp-exporter helm chart on Azure Kubernetes Service (AKS)


    To deploy the SNMP Exporter Helm chart on Azure Kubernetes Service (AKS), we'll go through the following processes:

    1. Set Up an AKS Cluster: First, we'll create an AKS cluster using the Pulumi Azure Native provider. This is a managed Kubernetes service that enables the quick deployment of cluster configurations.

    2. Install Helm Release: Once we have an AKS cluster, we'll need to deploy the SNMP Exporter application into it. We'll use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider, which allows us to manage Helm chart releases.

    Below is a TypeScript program that outlines each step to achieve your goal. Make sure you have Pulumi CLI installed and configured with your Azure account. You'll also need to have kubectl installed to interact with your Kubernetes cluster.

    import * as pulumi from "@pulumi/pulumi"; import * as azure from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an Azure Resource Group const resourceGroup = new azure.resources.ResourceGroup("resourceGroup", { resourceGroupName: "snmpExporterRG", }); // Step 2: Create an AKS cluster const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 1, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGB: 30, osType: "Linux", type: "VirtualMachineScaleSets", vmSize: "Standard_DS2_v2", }], dnsPrefix: "aks-snmpexporter", enableRBAC: true, kubernetesVersion: "1.18.14", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa YOUR_SSH_PUBLIC_KEY", }], }, }, resourceGroupName: resourceGroup.name, nodeResourceGroup: "PulumiNodeResourceGroup", }); // Step 3: Configure Kubernetes Provider to use the AKS cluster const creds = pulumi.all([aksCluster.name, resourceGroup.name]).apply(([aksClusterName, rgName]) => { return azure.containerservice.listManagedClusterUserCredentials({ resourceName: aksClusterName, resourceGroupName: rgName, }); }); const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: creds.apply(creds => creds.kubeconfigs[0].value), }); // Step 4: Deploy the SNMP Exporter Helm chart to AKS const snmpExporterChart = new k8s.helm.v3.Chart("snmp-exporter", { repo: "prometheus-community", chart: "snmp-exporter", version: "0.1.0", // replace with the desired chart version namespace: "default", }, { provider: k8sProvider }); // Export the AKS cluster's kubeconfig export const kubeconfig = creds.apply(creds => creds.kubeconfigs[0].value);


    In the above program:

    • Resource Group: We start by creating an Azure Resource Group, which serves as a logical container for the AKS cluster and its associated resources.

    • AKS Cluster: We define an AKS cluster resource with one node pool and enable RBAC for security. You need to replace "ssh-rsa YOUR_SSH_PUBLIC_KEY" with your actual SSH public key.

    • Kubernetes Provider: We retrieve the AKS cluster's credentials to configure the Pulumi Kubernetes provider. This allows Pulumi to communicate with the cluster.

    • Helm Chart: Using the Pulumi Kubernetes provider, we deploy the SNMP Exporter Helm chart to the AKS cluster. Replace 0.1.0 with your desired chart version.

    • Export kubeconfig: Finally, we export the kubeconfig, which allows you to interact with your Kubernetes cluster using kubectl.

    To run this Pulumi program, save the code in a file named index.ts, then run pulumi up via the Pulumi CLI to create the resources. You can then use the exported kubeconfig to interact with the AKS cluster and verify that the Helm chart has been deployed successfully.
