Deploy the jwks-merge helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an OpenShift cluster can be done using the Pulumi Kubernetes provider. The jwks-merge Helm chart would typically be deployed to manage JSON Web Key Sets (JWKS) for your applications running within OpenShift.

To start, you need to have your OpenShift cluster already set up and kubectl configured to communicate with the cluster. You will also need to have Pulumi installed and set up on your machine to run the program.

Below is the TypeScript program that demonstrates how to use Pulumi to deploy the jwks-merge Helm chart to an OpenShift cluster. The program assumes you have an existing Helm chart for jwks-merge. If the Helm chart is available in a public repository, you would include the repository URL. If it is a local chart, you should provide the filesystem path to the chart.

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

// Create a Kubernetes provider instance that targets your OpenShift cluster.
const openshiftProvider = new k8s.Provider("openshiftProvider", {
    // kubeconfig can be set explicitly or Pulumi will use the standard kubeconfig location
    // if no configuration is provided.
    // kubeconfig: "<Your kubeconfig contents here, if needed>"
});

// Install the JWKS-Merge Helm chart. If your chart is in a remote repository,
// make sure to add the 'repo' property.
const jwksMergeChart = new k8s.helm.v3.Chart("jwks-merge", {
    chart: "jwks-merge", // Your chart name here.
    // Uncomment and set the repo property if your chart is in a remote repository.
    // repo: "https://example.com/helm-charts",
    // version can be specified if you want a specific chart version.
    // version: "x.y.z",
    values: {}, // Set your desired values for the Helm chart.
}, { provider: openshiftProvider });

export const chartName = jwksMergeChart.metadata.apply(meta => meta.name);

This program creates a new instance of a Kubernetes provider that points to your OpenShift cluster. Then, it uses the Chart resource to install the jwks-merge Helm chart.

Here are the steps you need to follow:

First, replace <Your kubeconfig contents here, if needed> with the contents of your kubeconfig file if it is not located in the default location (~/.kube/config) or if you wish to provide its configuration explicitly.
Set the chart property to the name of your jwks-merge Helm chart.
If your Helm chart is hosted in a remote repository, you'll need to uncomment the repo property and set its value to your Helm chart's repository URL.
If you want to deploy a specific version of the Helm chart, uncomment the version property and set its value.
In the values object, provide any specific configuration you want to pass to your Helm chart. This would be the equivalent of a values.yaml file you might use with the helm CLI tool.
Run the Pulumi program with pulumi up.

Note that this example does not handle OpenShift-specific authentication or project setup within OpenShift. It assumes you have sufficient permissions to deploy applications into the default namespace, or you have adjusted the code to target a specific OpenShift project.

After running the Pulumi program, the jwks-merge Helm chart will be deployed to your OpenShift cluster. The export statement at the end exposes the name of the deployed chart for easy reference. You can use Pulumi's output to further automate processes or integrate this deployment step into larger infrastructure management tasks.
