1. Deploy the glowroot helm chart on Opensshift


    To deploy the Glowroot Helm chart on an OpenShift cluster, you will use the kubernetes.helm.v3.Chart resource from Pulumi's Kubernetes provider. This resource allows you to deploy Helm charts within a Kubernetes cluster, which OpenShift is built on top of. Before you start, you should have Pulumi installed, an OpenShift cluster available, and the oc command-line tool configured to access your cluster.

    The process involves creating a new Pulumi project, defining the Helm chart deployment in TypeScript, and running pulumi up to apply the changes to your cluster.

    Below is a Pulumi program in TypeScript that defines the deployment:

    1. Install the necessary Pulumi packages by running the following:
    npm install @pulumi/pulumi @pulumi/kubernetes
    1. Here's the TypeScript code that deploys the Glowroot Helm chart:
    import * as kubernetes from "@pulumi/kubernetes"; // Define the Helm chart for Glowroot. You must specify the correct repository URL and chart name. const glowrootChart = new kubernetes.helm.v3.Chart("glowroot", { // The OpenShift namespace where you want to deploy Glowroot. Change it to your desired namespace. namespace: "glowroot-namespace", chart: "glowroot", version: "0.1.0", // Specify the version of the chart you want to deploy. fetchOpts: { repo: "https://helm-repository-url/", // Replace with the Helm repository URL that has the Glowroot chart. }, // If you have any custom values to provide to the chart, specify them here. // For example, to set the service type to `NodePort`: values: { service: { type: "NodePort", }, }, }, { provider: openshiftProvider }); // Export the chart name and version. export const chartName = glowrootChart.metadata.apply(m => m.name); export const chartVersion = glowrootChart.version.apply(v => v.toString()); // Note: Replace 'openshiftProvider' with an appropriate Kubernetes Provider instance that points to your OpenShift cluster.

    Here's what the program does:

    • Imports the Pulumi Kubernetes package.
    • Defines a Helm chart resource for deploying Glowroot.
    • Sets the namespace, chart name, and version.
    • Optionally, if you have custom values for the Helm chart (like service type or other configurations), you can provide them in the values property.
    • Exports the chart name and the version of the chart for easy access.

    To run this program:

    • Save the code to a file named index.ts.
    • Use the Pulumi CLI to create a new stack, which represents an isolated deployment target in your project:
      pulumi stack init dev
    • Run the following command to preview and then deploy the changes:
      pulumi up
    • When prompted, confirm the deployment by selecting yes.

    Please ensure you replace the placeholders in the code like the namespace, chart version, Helm repository URL, and possibly the values object with the details that fit your requirements.

    Remember that the openshiftProvider referenced in the code needs to be created and configured according to your OpenShift cluster. For OpenShift, you may need to use the Kubernetes provider configuration specific to OpenShift's requirements to ensure proper authentication and permissions.

    Lastly, always consult the official Glowroot Helm chart documentation and its values.yaml file to understand all the configurable parameters.
