Deploy the burrow helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart, like the Burrow Helm chart, on an OpenShift cluster using Pulumi, you would typically define the chart using Pulumi's Kubernetes package. This package contains resources that can be used to manage Kubernetes resources, including deploying Helm charts.

Below, I'll provide a Pulumi program written in TypeScript that demonstrates how to deploy the Burrow Helm chart on an OpenShift cluster. The main resource we’ll be using is kubernetes.helm.sh/v3.Chart which is responsible for deploying Helm charts.

First, make sure you have Pulumi installed and configured for use with your OpenShift cluster. You'll need kubectl configured with the context of the OpenShift cluster you intend to deploy to.

Here's a complete Pulumi program that deploys the Burrow Helm chart to your OpenShift cluster:

import * as k8s from "@pulumi/kubernetes";

// Create a Kubernetes provider for OpenShift by giving the context of your OpenShift cluster.
// This assumes you have already set up your kubeconfig file to point at your OpenShift cluster.
const openshiftProvider = new k8s.Provider("openshift-k8s", {
    kubeconfig: "<your kubeconfig>", // Replace with your kubeconfig or path to your kubeconfig file
});

// Define the settings for the Helm chart deployment.
// Replace the variables with the actual values needed for your Burrow Helm chart.
const burrowChart = new k8s.helm.v3.Chart("burrow", {
    // Assuming 'burrow' is available in a public Helm repository, specify that repository below.
    // If it's in a private repository, you'll have to pass additional parameters as needed.
    chart: "burrow",
    version: "<chart version>", // Replace with the version of the chart you wish to deploy
    namespace: "default", // Replace with the namespace where you want to install the chart
    values: {
        // Specify any custom values needed by Burrow chart. 
        // For example:
        // serviceType: "LoadBalancer",
        // replicaCount: 1,
        // If your chart requires extensive custom values, it might be better to import a .yaml file
        // You can import a YAML file with values using `fs` module.
    },
}, { provider: openshiftProvider });

// Export any relevant outputs; for example, if your chart creates a LoadBalancer service,
// you may want to export the endpoint.
export const burrowEndpoint = burrowChart.getResourceProperty("v1/Service", "burrow-service", "status");

In the code snippet above, we import the necessary Pulumi Kubernetes package and define a kubernetes provider that connects to our OpenShift cluster. The provider uses the kubeconfig of the cluster to authenticate.

Next, a new instance of the Chart resource is created, representing the Burrow Helm chart. The namespace, values, and chart version must match the ones required by the Burrow Helm chart you want to deploy.

This program assumes that you have a kubeconfig file configured for accessing your OpenShift cluster and that you replace placeholders like <your kubeconfig> and <chart version> with actual values. You will need to check the configuration options of the Burrow Helm chart you are using to correctly set the values section.

Lastly, if any output from the chart deployment is helpful, such as the endpoint of a LoadBalancer service the chart might create, this is exported using export const. This allows you to get easy access to important information once the deployment completes.

To run this program, save it to a file (for example, index.ts), ensure that you have all the node modules installed by running npm install or yarn, and then execute it using the Pulumi CLI with the command pulumi up. This will start the deployment process. Make sure to follow any additional setup or prerequisites required by the specific Helm chart or your OpenShift cluster.
