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


    To deploy the Glowroot Helm chart on Azure Kubernetes Service (AKS), we will perform the following steps using Pulumi:

    1. Create an AKS cluster: We'll set up a managed Kubernetes cluster on Azure using the azure-native provider.
    2. Install the Helm chart: Once the AKS cluster is ready, we'll deploy the Glowroot Helm chart onto it using Pulumi's Helm support.

    Let's first create an AKS cluster using azure-native provider. We'd set up a basic cluster, which includes a default node pool. For this, you'll need an existing resource group or you can create one as part of the setup. The following code assumes you already have an Azure Resource Group defined where your AKS cluster will reside.

    Once the AKS cluster is created, we will then deploy the Glowroot Helm chart to the cluster. To do this, we will need Pulumi's kubernetes provider that supports deploying Helm charts directly. The chart can be found within the public Helm chart repositories or may need to be referenced by a URL if it is custom or private. In this example, we'll assume the chart is publicly available.

    Now let's proceed with writing the Pulumi TypeScript code.

    import * as pulumi from "@pulumi/pulumi"; import * as azureNative from "@pulumi/azure-native"; import * as k8s from "@pulumi/kubernetes"; // Replace the following with your own names if needed const resourceGroupName = "myResourceGroup"; const clusterName = "myAKSCluster"; // Create an AKS cluster const aksCluster = new azureNative.containerservice.ManagedCluster(clusterName, { resourceGroupName: resourceGroupName, agentPoolProfiles: [{ count: 1, // Number of nodes in the node pool vmSize: "Standard_DS2_v2", // VM size (make sure it's available in the chosen location) mode: "System", name: "agentpool", }], dnsPrefix: `${clusterName}-dns`, // DNS prefix for the AKS cluster identity: { type: "SystemAssigned", // Specify identity type for the cluster (this example uses SystemAssigned identity) }, }); // Export the kubeconfig to access the AKS cluster export const kubeconfig = aksCluster.kubeConfigRaw; // Setup a Kubernetes provider to deploy a Helm chart to the AKS cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeconfig, }); // Deploy the Glowroot Helm chart to the AKS cluster using the Kubernetes provider const glowrootChart = new k8s.helm.v3.Chart("glowroot", { chart: "glowroot", // Replace with the correct chart name if needed version: "0.13.6", // Replace with the correct chart version if needed fetchOpts: { repo: "https://repo.chart.com", // Replace with the correct Helm chart repository URL }, }, { provider: k8sProvider }); // Export any needed resource properties // for example if the Glowroot chart creates a LoadBalancer service to access the app export const glowrootEndpoint = glowrootChart.getResourceProperty("v1/Service", "glowroot", "status").apply(status => { return status.loadBalancer.ingress[0].ip; });

    To run this code:

    1. Ensure you have Pulumi installed and configured with your Azure credentials.
    2. Save the above code to a file with a .ts extension, for example, index.ts.
    3. Run pulumi stack init to create a new stack.
    4. Run pulumi up to provision the resources as specified in the code.

    In the code, we:

    • Import the necessary Pulumi packages.
    • Define the resource group and cluster names.
    • Create a new AKS cluster with a single node pool using the azure-native.containerservice.ManagedCluster resource.
    • Export the raw Kubeconfig of the AKS cluster to be used by the Kubernetes provider.
    • Create a new k8s.Provider that uses the exported kubeconfig for authentication.
    • Deploy the Glowroot Helm chart to the AKS cluster by creating a k8s.helm.v3.Chart resource, which refers to the Kubernetes provider.
    • Optionally, if the Glowroot Helm chart creates a LoadBalancer type service, we export the endpoint IP address so it can be easily accessed. You'd replace the placeholder information like the Helm repository URL and version with those that match the intended Glowroot chart configuration.

    Please make sure to replace the placeholder values and adjust the parameters like node size, the number of nodes, and chart version to match your desired setup and the actual Helm chart details for Glowroot.
