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


    To deploy the Prometheus-Beanstalkd-Exporter Helm chart on Azure Kubernetes Service (AKS), we will follow these steps:

    1. Set up an AKS cluster using Pulumi's Azure Native provider.
    2. Configure kubectl to communicate with the AKS cluster.
    3. Use Pulumi's Helm release resource to deploy the Prometheus-Beanstalkd-Exporter chart to the AKS cluster.

    Before writing the program, ensure you have the following prerequisites in place:

    • Pulumi CLI installed and configured for use with Azure.
    • An Azure account with the appropriate permissions to create resources.
    • Azure CLI installed and logged into your Azure account.

    Here's the TypeScript program to create an AKS cluster and deploy the Helm chart:

    import * as azure from "@pulumi/azure"; import * as azuread from "@pulumi/azuread"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure.core.ResourceGroup("aksResourceGroup", { location: "East US", // You can change the location according to your preference }); // Create an Azure AD service principal for the AKS 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 an AKS cluster const k8sCluster = new azure.containerservice.KubernetesCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osDiskSizeGb: 30, osType: "Linux", vmSize: "Standard_DS2_v2", vnetSubnetId: null, // If you have an existing VNet/Subnet you would like to attach, pass the ID of subnet here }], dnsPrefix: "aksCluster", linuxProfile: { adminUsername: "aksuser", sshKeys: [{keyData: "ssh-rsa ..."}], // replace ... with your SSH public key }, servicePrincipal: { clientId: adApp.applicationId, clientSecret: adSpPassword.value, }, kubernetesVersion: "1.18.14", roleBasedAccessControl: {enabled: true}, networkProfile: { networkPlugin: "azure", serviceCidr: "", dnsServiceIp: "", dockerBridgeCidr: "", }, }, {dependsOn: [adApp, adSp, adSpPassword]}); // Export the cluster kubeconfig export const kubeconfig = pulumi.all([k8sCluster.name, resourceGroup.name]).apply(([name, rgName]) => { return azure.containerservice.getKubeConfig({ name: name, resourceGroupName: rgName, }).then(kubeconfig => kubeconfig.kubeconfigs[0].value); }); // Create a Kubernetes provider instance that uses our cluster from above. const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the prometheus-beanstalkd-exporter Helm chart const prometheusBeanstalkdExporter = new k8s.helm.v3.Chart("prometheusBeanstalkdExporter", { chart: "prometheus-beanstalkd-exporter", // Specify the Helm repository here. This example assumes you have the chart available from a known Helm repo. // You may need to add the repository with `helm repo add` command or specify repositoryOpts in ChartArgs. fetchOpts: { repo: "https://helm-repo.example.com/charts", }, version: "1.0.0", // Specify the version of the chart you want to deploy values: { // Configure your Helm chart values here, such as replica count or image versions. }, }, {provider: k8sProvider}); // Export the Prometheus-Beanstalkd-Exporter service endpoint export const beanstalkdExporterEndpoint = prometheusBeanstalkdExporter.getResource("v1/Service", "default", "prometheus-beanstalkd-exporter").status.apply(status => status.loadBalancer.ingress[0].ip);

    Let's break down what the program is doing:

    1. Resource Group: We create an Azure resource group that will contain our AKS cluster and related resources.

    2. Service Principal: An Azure Active Directory (AD) service principal is created for the Kubernetes cluster to interact with other Azure services on your behalf. The azuread.Application, azuread.ServicePrincipal, and azuread.ServicePrincipalPassword resources are involved here.

    3. AKS Cluster: Using the azure.containerservice.KubernetesCluster resource, we define the characteristics of our AKS cluster, such as the size of the nodes and the version of Kubernetes.

    4. Kubeconfig Export: We export the kubeconfig, which will allow kubectl and Pulumi's Kubernetes provider to interact with the cluster.

    5. Kubernetes Provider: This is a Pulumi provider that allows us to deploy Kubernetes resources onto the AKS cluster. It uses the exported kubeconfig from the cluster we created.

    6. Helm Chart Release: Finally, we deploy the Prometheus-Beanstalkd-Exporter by
