Deploy the uistio helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an OpenShift cluster with Pulumi involves a few steps.

First, you need to have access to an OpenShift cluster. Pulumi does not create the cluster for you in this example; please ensure you have your OpenShift cluster up and running. You also need to have kubectl configured to communicate with your OpenShift cluster.

We'll use the kubernetes package from Pulumi to deploy the istio Helm chart, which provides resources for managing Kubernetes resources, including deploying Helm charts.

Here's how you would use Pulumi to deploy the "uistio" Helm chart, which I assume is a typo and you meant "istio" Helm chart. If "uistio" is a custom Helm chart, then you must ensure that the Helm chart is accessible to your Pulumi program, either by placing the chart in a reachable Helm repository or by specifying the path to the chart on your local file system:

Configuring Pulumi to Use Your Kubernetes Cluster: Pulumi uses the Kubernetes provider to interact with your Kubernetes cluster. It automatically uses the current context from your kubeconfig file (~/.kube/config by default). You must ensure your kubeconfig is configured appropriately to connect to your OpenShift cluster.
Installing the Helm Chart: The Chart resource from Pulumi's Kubernetes package is used to specify the Helm chart you want to deploy. You will need to provide details such as the chart name, version, and any values you want to override.
Checking Deployment Status: Pulumi will perform deployment and provide output on the command line. You can also use Pulumi's query and state commands to check on the deployment status and details about the running resources.

Here is the code that accomplishes this:

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

const chartName = "istio";
const chartVersion = "1.5.1"; // replace with the desired chart version
const chartRepo = "https://istio-release.storage.googleapis.com/charts"; // URL to the repository where the chart is located
const namespace = "istio-system"; // specify the namespace where the chart will be installed

// Create a chart instance for Istio
const istioChart = new k8s.helm.v3.Chart(chartName, {
    // Replace with the corresponding values for your Istio Helm chart.
    chart: chartName,
    version: chartVersion,
    fetchOpts: {
        repo: chartRepo,
    },
    namespace: namespace,
    values: {
        // Provide any specific configuration values here.
        // For example, you can enable the tracing feature by setting the following:
        // tracing:
        //   enabled: true,
    },
}, { provider: new k8s.Provider("openshift", { kubeconfig: "<kubeconfig-content>" }) });

// Export the status of the deployment
export const istioStatus = istioChart.status;

Notes:

Replace <kubeconfig-content> with the actual contents of your kubeconfig file if it's not using the default location or the default context.
You may need to adjust the values property to configure Istio according to your requirements, or pass in an existing values.yaml file content in the appropriate format.
The chart name and repository are typical values for deploying Istio but may need to be changed depending on the version and source of the Helm chart you are deploying.
It's important to verify the correct version of the Helm chart and the repository URL before attempting to deploy the chart.

To run this code and deploy your chart, you would need to have Pulumi installed and properly configured for TypeScript, install @pulumi/kubernetes npm package and execute this Pulumi program in your Pulumi environment. After that, run pulumi up to initiate the deployment process.
