Deploy the ibm-license-service-instance helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on OpenShift with Pulumi involves several steps. We will define a Pulumi program that will:

1. Set up a Kubernetes provider that targets an OpenShift cluster.
2. Use the `kubernetes.helm.sh/v3.Chart` resource to deploy the Helm chart.

Below is a detailed Pulumi TypeScript program to achieve these steps:

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

// Step 1: Configure the Kubernetes provider to target your OpenShift cluster
// You would typically use the KUBECONFIG environment variable or the kubeconfig file to configure access to your OpenShift cluster.
const k8sProvider = new k8s.Provider("openshiftK8s", {
    kubeconfig: process.env.KUBECONFIG, // replace with the kubeconfig contents or path if needed
});

// Step 2: Define a Helm chart resource for the IBM license service instance
const ibmLicenseServiceChart = new k8s.helm.v3.Chart("ibm-license-service-instance", {
    chart: "ibm-license-service", // This should match the name of the chart in the Helm repository
    version: "1.2.3", // Specify the version of the chart you want to deploy
    namespace: "default", // Specify the namespace where the chart should be deployed
    fetchOpts: {
        repo: "https://charts.your-repository.com/", // Replace with the URL of the repository containing your chart
    },
    // If your chart requires custom values, specify them in `values`
    values: {
        // Custom values go here - this is just an example
        service: {
            type: "ClusterIP",
        },
    },
}, { provider: k8sProvider });

// Step 3: Export any relevant information after the deployment.
// For example, if your chart creates a service and you want to export its cluster IP:
export const serviceClusterIP = ibmLicenseServiceChart.getResourceProperty("v1/Service", "ibm-license-service", "spec.clusterIP");

```

This program sets up:

- A Kubernetes provider that points at your OpenShift cluster. Here it's assumed that you have set the `KUBECONFIG` environment variable to point at your cluster. Alternatively, you can directly embed the contents of your `kubeconfig` file in the `kubeconfig` field.
- The `kubernetes.helm.v3.Chart` resource specifies the Helm chart to be deployed. The `chart` and `version` specify the chart's name and version. The `repo` is the repository's URL where the Helm chart is located.
- The `values` property is used to pass any required values that your Helm chart needs.

After running `pulumi up` with this program, Pulumi will deploy the specified IBM license service instance Helm chart into the OpenShift cluster. The example assumes that you are deploying a chart named `ibm-license-service` and you have a repository containing this chart.

Please ensure to replace the chart name, version, and repository URL with those matching the Helm chart you want to deploy. You will also need to configure any required chart values.

Remember, you need the Pulumi CLI installed and configured to run this program. Additionally, you need to have access to your OpenShift cluster and Helm chart's repository.
