1. Deploy the glowroot helm chart on Kubernetes


    To deploy the Glowroot Helm chart on Kubernetes using Pulumi, you'll first need to ensure you have Kubernetes cluster access configured for Pulumi, which typically means you have a kubeconfig file prepared and accessible by Pulumi.

    For simplicity, I'll demonstrate deploying the Glowroot Helm chart to a cluster with kubeconfig already set up. We'll use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider, which enables the management of Helm chart resources within a Kubernetes cluster.

    Here's a step-by-step TypeScript program that accomplishes this:

    1. First, you have to install the necessary Pulumi package for Kubernetes if you haven't already:

      npm install @pulumi/kubernetes
    2. Next, you'll use the Chart resource to deploy the Glowroot chart. For this example, we'll assume that the Glowroot Helm chart is available in one of the public Helm repositories. If it's in a private repository, you'll need to configure the repo property with the appropriate repository URL.

    The Chart resource takes several arguments: the first argument is the name of the Helm chart resource in the Pulumi program, the second argument is an object that specifies the chart details such as chart, version, values, etc.

    The values object is where you can specify any configurations that the Glowroot chart supports. Modify the values in the ChartArgs according to the specific configuration you require for Glowroot.

    Below is the program that deploys Glowroot using Pulumi:

    import * as k8s from "@pulumi/kubernetes"; const glowrootChart = new k8s.helm.v3.Chart("glowroot", { chart: "glowroot", version: "0.13.6", // Specify the version of Glowroot you want to deploy fetchOpts: { repo: "https://helm.glowroot.org", // Use the appropriate Helm repo URL here }, // You can specify additional configuration options that the chart supports here values: { // Examples of possible Glowroot Helm chart values: // adminPassword: "your-admin-password", // storage: { // capacity: "10Gi", // }, // These values need to come from the actual Glowroot Helm chart documentation }, }); // Export the base URL for the Glowroot service export const glowrootBaseUrl = glowrootChart.getResourceProperty("v1/Service", "glowroot", "status").apply(status => { // Assuming that Glowroot is exposed as LoadBalancer, adjust depending on actual service type const ingress = status.loadBalancer.ingress[0]; if (ingress.ip) { return `http://${ingress.ip}`; } else if (ingress.hostname) { return `http://${ingress.hostname}`; } });

    To understand what we have in the program:

    • We import the Pulumi Kubernetes library.
    • We create a new Helm chart resource which Pulumi will use to deploy Glowroot.
    • We specify the chart name, version, and repository location.
    • We could provide custom configuration values under the values key.
    • We expose a property of our Pulumi stack (in this case, the base URL of the Glowroot service) that might be needed for other operations or outputs.

    After you have written this program in a file (let's say index.ts), you can simply run it using the Pulumi CLI commands:

    pulumi up

    Remember that this is a high-level overview. To create an actual deployment, you'll need to ensure that your cluster is accessible and you have the right permissions to deploy Helm charts, and you may need to adjust your values to match the specific configuration of the Glowroot chart and your environment.

    Please consult the documentation for the Glowroot Helm chart to find all configurable values you can modify to suit your needs.
