Deploy the tekton-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the tekton-operator Helm chart on OpenShift using Pulumi, you need to follow these steps:

Set up Pulumi with the necessary provider for Kubernetes.
Create a new Pulumi project.
Define resources using the Kubernetes provider to deploy the Helm chart.

Below is a detailed explanation of the Pulumi program which accomplishes the deployment of the tekton-operator Helm chart on OpenShift.

Firstly, you'll need to import the required Pulumi and Kubernetes packages. The @pulumi/kubernetes package is used to interact with Kubernetes resources, including deploying Helm charts.

In the code, the kubernetes.helm.v3.Chart class from Pulumi's Kubernetes provider is instantiated to deploy the tekton-operator chart. This class is a high-level abstraction to deploy charts, and it requires some basic information such as the chart name and the repository where the chart can be found.

For the Chart class:

chart parameter specifies the name of the chart ("tekton-operator").
version parameter specifies the version of the chart you want to deploy. (This is optional; if you omit it, the latest version will be used).
fetchOpts parameter specifies retrieval options, where you can define the repository's URL.
Using the namespace parameter, you can deploy the chart within a specific namespace on your OpenShift cluster.

Now let's write the Pulumi program:

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

// Define the OpenShift provider configuration.
// This assumes you have the kubeconfig file in place.
const provider = new kubernetes.Provider("openshift", {
    kubeconfig: '<KUBE_CONFIG_CONTENT>',
});

// Deploy the tekton-operator Helm chart into the "tekton-operator" namespace.
const tektonOperatorChart = new kubernetes.helm.v3.Chart("tekton-operator", {
    chart: "tekton-operator",
    // Use the version suitable for you or omit for the latest version.
    version: "0.0.1",
    namespace: "tekton-operator",
    fetchOpts: {
        repo: "https://tekton-charts.storage.googleapis.com", // replace with the correct repo if necessary
    },
}, { provider: provider });

// Export the resources name of the Chart
export const chartName = tektonOperatorChart.metadata.name;

In the above code:

A new instance of the Pulumi Kubernetes provider is created. The kubeconfig is passed directly here. Ensure to replace <KUBE_CONFIG_CONTENT> with the actual content or the path of your kubeconfig file of your OpenShift cluster.
A new Helm chart resource named tekton-operator is declared. You need to replace "https://tekton-charts.storage.googleapis.com" with the actual Helm repository URL for the tekton-operator chart if it's different.
The chart is deployed in the namespace tekton-operator. If this namespace doesn't exist in your OpenShift cluster, it should be created beforehand, or you can set createNamespace: true in the Chart args to let Pulumi handle its creation.

Remember that you need to have appropriate permissions for deploying resources in your OpenShift cluster. This Pulumi program doesn't include role configurations or bindings.

To execute this program, you'll need to follow these basic steps:

Install Pulumi and configure it for TypeScript.
Create a new Pulumi project with pulumi new kubernetes-typescript.
Replace the content of index.ts with the code above.
Run pulumi up to preview and deploy these changes.

Please make sure that your Pulumi CLI is configured with access to your OpenShift cluster and that you have the necessary permissions to deploy and manage resources in the cluster.
