1. Deploy the grafaml helm chart on Azure Kubernetes Service (AKS)


    To deploy the Grafana Helm chart on an Azure Kubernetes Service (AKS) cluster, you will need to create several resources:

    1. AKS Cluster: The managed Kubernetes service provided by Azure where your Grafana Helm chart will be deployed.
    2. Helm Chart: Helm is a package manager for Kubernetes that allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm Charts help you define, install, and upgrade Kubernetes applications.

    Here is how you would deploy Grafana on AKS with Pulumi:

    • You will create an AKS cluster using Pulumi's azure-native package.
    • You will then use Pulumi's kubernetes package to install the Grafana Helm chart on the AKS cluster.

    Below is a step-by-step TypeScript program that uses Pulumi to perform this deployment:

    1. First, import the required Pulumi libraries. You need the azure-native library to interact with Azure resources, kubernetes to work with Kubernetes resources, and additionally, kubernetes.helm.v3 to work with Helm charts in Kubernetes.

    2. Then, set up the AKS cluster.

    3. Finally, deploy the Grafana Helm chart to the AKS cluster using the Helm Chart resource from Pulumi's Kubernetes SDK.

    Ensure you have the following prerequisites before running the code:

    • An Azure account with permissions to create resources.
    • Pulumi CLI installed and configured with Azure credentials.
    • kubectl installed to interact with the cluster.
    • Node.js and NPM installed since we are using TypeScript.

    Now, let's look at the Pulumi TypeScript program. The comments inside the code will guide you through what each section does.

    import * as pulumi from "@pulumi/pulumi"; import * as azure_native from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Create an Azure Resource Group const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup"); // Create an Azure AD Service Principal for the AKS cluster const adApp = new azure_native.graphrbac.Application("myAdApp", { availableToOtherTenants: false, displayName: "myAdApp", }); const adSp = new azure_native.graphrbac.ServicePrincipal("myAdSp", { appId: adApp.applicationId, }); const adSpPassword = new azure_native.graphrbac.ServicePrincipalPassword("myAdSpPassword", { servicePrincipalId: adSp.id, value: "your-strong-password", // Please replace with a secure password endDate: "2099-01-01T00:00:00Z", // Far future expiration }); // Create the AKS cluster const cluster = new azure_native.containerservice.ManagedCluster("myAksCluster", { resourceGroupName: resourceGroup.name, agentPoolProfiles: [{ count: 2, maxPods: 110, mode: "System", name: "agentpool", osType: "Linux", vmSize: "Standard_DS2_v2", }], dnsPrefix: "myakscluster", enableRBAC: true, kubernetesVersion: "1.18.14", linuxProfile: { adminUsername: "adminuser", ssh: { publicKeys: [{ keyData: "ssh-rsa YOUR_SSH_PUBLIC_KEY", // Replace with your SSH public key }], }, }, servicePrincipalProfile: { clientId: adSp.appId, secret: adSpPassword.value, }, }); // Expose the Kubernetes cluster name and kubeconfig export const clusterName = cluster.name; const creds = pulumi.all([cluster.name, resourceGroup.name]).apply(([clusterName, rgName]) => { return azure_native.containerservice.listManagedClusterUserCredentials({ resourceGroupName: rgName, resourceName: clusterName, }); }); const encodedKubeconfig = creds.kubeconfigs[0].value; export const kubeconfig = encodedKubeconfig.apply(enc => Buffer.from(enc, "base64").toString()); // Create a Kubernetes provider instance that uses our kubeconfig const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: kubeconfig, }); // Deploy the Grafana Helm chart using the Helm Chart resource with the Pulumi Kubernetes SDK const grafana = new k8s.helm.v3.Chart("grafana", { chart: "grafana", version: "6.1.17", // Use the version of the chart you desire namespace: "default", // The Kubernetes namespace to deploy into fetchOpts:{ repo: "https://grafana.github.io/helm-charts", }, }, { provider: k8sProvider }); // Export the Grafana service endpoint export const grafanaServiceEndpoint = grafana.getResourceProperty("v1/Service", "grafana", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Make sure to replace the placeholder your-strong-password with a password of your choice and YOUR_SSH_PUBLIC_KEY with your SSH public key.

    This program will:

    • Create an Azure Resource Group to contain all resources.
    • Set up an Azure AD application and service principal for AKS authentication.
    • Provision an AKS cluster with the defined properties such as node size and count.
    • Export the kubeconfig which is required to interact with the AKS cluster using kubectl.
    • Create a Kubernetes provider to interact with the AKS cluster using Pulumi.
    • Deploy the Grafana Helm chart to the AKS cluster.
    • Export the endpoint of the Grafana service for accessing the Grafana dashboard.

    To run this code:

    • Save the above in a file named index.ts.
    • Run pulumi up in the same directory as your code, which will execute the Pulumi program and provision all defined resources.
