1. Deploy the prometheus-storage-adapter helm chart on Azure Kubernetes Service (AKS)


    To deploy the Prometheus Storage Adapter Helm Chart on an Azure Kubernetes Service (AKS) cluster using Pulumi, we will follow a sequence of steps which include provisioning an AKS cluster and deploying the Helm chart to it. Below is an explanation, followed by a complete Pulumi program written in TypeScript, to accomplish this task.


    We will perform the following actions:

    1. Define the required Azure resource group using the @pulumi/azure-native package.
    2. Provision an AKS cluster in the Azure resource group using the @pulumi/azure-native package.
    3. Deploy the Prometheus Storage Adapter Helm chart to the provisioned AKS cluster using the @pulumi/kubernetes package.

    Here's a step-by-step guide through the code:

    Step 1: Define Azure Resource Group

    Firstly, we create a new Azure resource group to logically organize our AKS cluster. This resource group will contain all the resources associated with our AKS cluster.

    Step 2: Provision AKS Cluster

    Secondly, we provision an AKS cluster within the resource group we've created. For that, we specify the AKS cluster's configuration, including the number of nodes and the node size.

    Step 3: Configure Kubernetes Provider

    Once the AKS cluster is up and running, we configure the Pulumi Kubernetes provider to target this specific AKS cluster. This includes obtaining the KubeConfig from the AKS cluster which is used by the Kubernetes provider to authenticate and communicate with the cluster.

    Step 4: Deploy Helm Chart

    Finally, we deploy the Prometheus Storage Adapter Helm chart using the @pulumi/kubernetes package. We set the chart's release name, repository, and version, and provide additional configuration as needed for the storage adapter.

    Now, let's jump into the TypeScript program:

    import * as pulumi from '@pulumi/pulumi'; import * as azure from '@pulumi/azure-native'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create a new Azure resource group const resourceGroup = new azure.resources.ResourceGroup("aksResourceGroup", { resourceGroupName: "prometheusAdapterGroup", location: "WestUS", // Adjust the location as needed }); // Step 2: Provision AKS Cluster const aksCluster = new azure.containerservice.ManagedCluster("aksCluster", { resourceGroupName: resourceGroup.name, location: resourceGroup.location, agentPoolProfiles: [{ count: 2, // Number of nodes vmSize: "Standard_DS2_v2", // VM size for nodes name: "agentpool", // Node pool name mode: "System", }], dnsPrefix: "aks-prometheus", // Enable RBAC for best security practices enableRBAC: true, }); // Obtain the KubeConfig (later used to configure Kubernetes provider) const creds = pulumi.output(azure.containerservice.listManagedClusterUserCredentials({ resourceGroupName: resourceGroup.name, resourceName: aksCluster.name, })); const kubeconfig = creds.apply(creds => { const encoded = creds.kubeconfigs[0].value; return Buffer.from(encoded, 'base64').toString(); }); // Step 3: Set up the Kubernetes provider to connect to the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Step 4: Deploy the Prometheus Storage Adapter Helm chart const prometheusStorageAdapterChart = new k8s.helm.v3.Chart("prometheusStorageAdapter", { chart: "prometheus-storage-adapter", version: "your-chart-version", // Specify the chart version fetchOpts: { repo: "https://your-helm-chart-repository/", // Specify the Helm chart repository }, // Provide values for the Helm chart values: { // Define necessary values here }, }, { provider: k8sProvider }); // Export the AKS cluster name and kubeconfig export const clusterName = aksCluster.name; export const kubeConfig = kubeconfig;

    Make sure to replace your-chart-version with the actual version of the Prometheus Storage Adapter chart and https://your-helm-chart-repository/ with the chart's repository URL. You can find the repository URL and chart version in the Helm chart's documentation or by searching Helm repositories online.

    Save this file with a .ts extension, make sure you have Pulumi installed, and then run pulumi up to deploy your infrastructure.


    After running the above program, you'll have an AKS cluster with the Prometheus Storage Adapter deployed via Helm. This setup will allow you to use Prometheus in combination with Azure services for monitoring purposes, with storage functionalities handled by the deployed adapter.

    Keep in mind that some properties and values such as the number of nodes, VM size, chart version, and repository URL should be tailored to meet your specific requirements and the latest available software versions.
