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


    To deploy the Prometheus Federation Helm chart on Azure Kubernetes Service (AKS), we'll perform the following steps using Pulumi written in TypeScript:

    1. Set up an AKS cluster.
    2. Install Prometheus Federation using Helm.

    We'll use the azure-native provider, which interfaces directly with Azure's Resource Manager API to provision an AKS cluster. Then, we will use Pulumi's Kubernetes provider to interact with the AKS cluster and deploy the Prometheus Federation Helm chart.

    Step 1: Set up an AKS cluster

    We begin by creating the resources necessary for the AKS cluster. In this case, we need to create the following:

    • A resource group to contain all of our Azure resources.
    • An AKS cluster within that resource group.

    Step 2: Install Prometheus Federation using Helm

    Once the AKS cluster is up and running, we'll use Pulumi's Kubernetes (K8s) provider to deploy the Prometheus Federation Helm chart. Prometheus Federation is set up by deploying a Helm chart to the Kubernetes cluster; this Helm chart is a package that contains all the necessary definitions for running Prometheus in a federated configuration.

    Here's how you could write a complete Pulumi program in TypeScript to do just that:

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create a new Azure resource group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Create an AKS cluster const cluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, vmSize: "Standard_DS2_v2", name: "agentpool", mode: "System", }], dnsPrefix: "myakscluster", enableRBAC: true, kubernetesVersion: "1.19.11", }); // Export the AKS cluster kubeconfig export const kubeConfig = cluster.kubeConfig.apply(c => c.raw); // Create a K8s provider instance that uses the generated kubeconfig from the AKS cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeConfig, }); // Deploy the Prometheus Federation Helm chart const chart = new k8s.helm.v3.Chart("prometheus-federation", { chart: "kube-prometheus-stack", version: "20.0.1", namespace: "monitoring", fetchOpts: {repo: "https://prometheus-community.github.io/helm-charts"}, values: { prometheus: { prometheusSpec: { // Add your specifications for federation here }, }, }, }, {provider: k8sProvider}); // Export the endpoint to access the Prometheus server export const prometheusEndpoint = pulumi.interpolate`http://${chart.getResourceProperty("v1/Service", "monitoring", "prometheus-kube-prometheus-prometheus", "status").loadBalancer.ingress[0].ip}`;

    In this program:

    • We define the AKS cluster using azure_native.containerservice.ManagedCluster. We set the number of nodes, their size, and enable RBAC, among other settings.
    • We then export the kubeconfig required to interact with the AKS cluster.
    • We set up a Pulumi Kubernetes provider with the obtained kubeconfig which will allow Pulumi to communicate with our AKS cluster.
    • For the Helm chart deployment, we specify kube-prometheus-stack, which provides a comprehensive setup of Prometheus that we're labeling as prometheus-federation for this purpose. In the values section, you can specify additional Prometheus configuration.
    • Finally, we export an endpoint for the Prometheus server that will be created as part of the Helm chart deployment. It might take a few minutes for the endpoint to be available after the deployment is completed.


    • Before running this Pulumi program, you should have Pulumi CLI installed and configured, along with kubectl pointing at your AKS cluster.
    • Ensure you have access rights to deploy resources and Helm charts within the specified AKS cluster.
    • This example uses a specific version (1.19.11) of Kubernetes for the AKS cluster and a specific version (20.0.1) for the Helm chart. These may need to be updated according to the versions you intend to use and those supported by your cloud provider.
    • Adjust the Prometheus configuration within the values object to the specifics of your federation requirements.
    • The kube-prometheus-stack chart may have different parameters; consult the chart's documentation for configuration details.
