Deploy the mogenius-namespace helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you will use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart by providing the name of the chart, any custom values you want to override, and the namespace to which you'd like to deploy.

Below you will find a Pulumi TypeScript program that shows how to deploy the mogenius-namespace Helm chart to an OpenShift cluster. Please ensure you have the Helm chart available and accessible for Pulumi, in a Helm repository or as a local chart for example.

Firstly, make sure you've installed the necessary Pulumi packages by running:

npm install @pulumi/kubernetes

Then create a new TypeScript file (e.g., index.ts) and write the following Pulumi program:

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

// Create a new Helm Chart resource that will deploy the mogenius-namespace chart.
const mogeniusNamespaceChart = new k8s.helm.v3.Chart("mogenius-namespace", {
    // You need to specify the repo URL where the Helm chart is located.
    // If it's a local chart, you can point to the local path instead.
    // For the sake of this example, I will assume the chart is in a Helm repository.
    // Replace `<REPO_URL>` with the actual repository URL.
    chart: "mogenius-namespace",
    version: "1.0.0", // replace this with the actual chart version
    namespace: "default", // replace this with the desired namespace
    fetchOpts: {
        repo: "<REPO_URL>", // specify the Helm repository containing the chart
    },
    // If the Helm chart requires custom values, provide them as an object.
    values: {
        // ... provide any custom values here
    },
});

// Export the resulting chart's resources, if needed
export const chartResources = mogeniusNamespaceChart.resources;

Make sure you replace <REPO_URL> with the actual Helm repository URL or local chart path, and provide any custom values needed by the chart.

Before running the Pulumi program, make sure your Pulumi CLI is configured to communicate with your OpenShift cluster. Typically, Pulumi uses your local kubeconfig file, which should be set up and configured to point to your OpenShift cluster.

To deploy the Helm chart using Pulumi, run the following command:

pulumi up

The Pulumi CLI will prompt you to confirm the deployment before proceeding. Once confirmed, Pulumi will apply the Helm chart to your OpenShift cluster, and you will see the outputs on your console. If you export resources or any other outputs, Pulumi will display them too.

Keep in mind that deploying to an OpenShift cluster might require additional permissions, and depending on the configuration, you might need to log in to your OpenShift cluster using the oc command-line tool and switch to the correct user context that has the required permissions.

Remember to review the Helm chart documentation or its values.yaml file to understand which values you can customize. Adjust the values property in the Pulumi program accordingly if customization is necessary for your deployment scenario.
