1. Deploy the riemann helm chart on Kubernetes

    TypeScript

    To deploy the Riemann Helm Chart on a Kubernetes cluster using Pulumi, we will follow these steps:

    1. Setup Kubernetes: Make sure you have a Kubernetes cluster running and the kubectl CLI tool configured with access to your cluster. Pulumi interacts with the cluster configuration that kubectl uses.

    2. Install Pulumi: If you haven't already installed Pulumi, please follow the instructions on Pulumi's installation guide.

    3. Configure Pulumi for TypeScript: Create a new directory for your project, change into it, and run pulumi new typescript to create a new Pulumi project using TypeScript.

    4. Write the Pulumi Program: We're going to use the Chart resource from the @pulumi/kubernetes package to deploy the Riemann Helm Chart. This package is capable of interacting with the Helm package manager to deploy charts into Kubernetes clusters.

    5. Preview and Deploy: Run pulumi preview to preview the deployment changes and pulumi up to perform the deployment.

    Below, you'll find a Pulumi program written in TypeScript to deploy the Riemann Helm Chart:

    import * as k8s from "@pulumi/kubernetes"; const riemannChart = new k8s.helm.v3.Chart("riemann", { chart: "riemann", version: "1.0.0", // Specify the exact chart version, adjust this as per the chart you are using. fetchOpts: { repo: "https://helm.riemann.io/", // Use the correct Helm repository URL for the Riemann chart. }, // If you have specific values you wish to override in the Helm Chart, you can include them here. values: { // For example, you can set the service type to be of type LoadBalancer if exposed externally // service: { // type: "LoadBalancer", // }, }, }); // Export any of the resources' properties that are required. // For instance, if you've exposed Riemann on a LoadBalancer, you might want to export the external IP. export const riemannExternalIp = riemannChart.getResourceProperty("v1/Service", "riemann", "status") .apply(status => status.loadBalancer.ingress[0].ip || "not-assigned");

    To run this Pulumi program:

    • Ensure you have a directory setup for your Pulumi project.
    • Place this TypeScript code into the index.ts file within your project directory.
    • Install the required NPM package by running npm install @pulumi/kubernetes.
    • Use pulumi preview to see the changes that will be made.
    • Apply the changes to your cluster by running pulumi up.

    The above program does the following:

    • Imports the Pulumi Kubernetes package.
    • Creates a new Helm chart deployment named "riemann" using Chart construct from Pulumi’s Kubernetes library.
    • Sets the chart to "riemann", which should match the chart you wish to deploy from the Helm repository.
    • Specifies a specific version of the chart to be deployed. The version number provided in the example is fictional, so you should replace it with the real version number that you require.
    • Includes an example of how you can override default values set in the Helm Chart. In this case, it's commented out, but you can uncomment and adjust the values to match your requirements.
    • Exports the external IP address that will be assigned to the Riemann service if it is exposed externally. This is useful for accessing Riemann after the deployment.

    Please adapt the values and settings to match the exact details of the Helm chart you are using and any specific configurations you need.
