Deploy the ara helm chart on Opensshift

Question

Pulumi · Accepted Answer

In order to deploy the `ara` helm chart on an OpenShift cluster with Pulumi, you will need to use the Pulumi Kubernetes provider. The `Chart` resource from the `@pulumi/kubernetes/helm` module can help us to deploy a helm chart to a Kubernetes cluster, including an OpenShift cluster which is essentially a Kubernetes distribution with additional features.

Below I will provide you with a Pulumi TypeScript program that demonstrates how to deploy the `ara` helm chart on an OpenShift cluster. To use this code, you will need to have access to an OpenShift cluster, and your `kubeconfig` file should be set up to connect to your OpenShift cluster.

Here is a detailed rundown of what the TypeScript program does:

1. **Import Required Modules**: The program starts by importing the necessary modules from the Pulumi library that we will use to create Kubernetes resources.

2. **Create a Helm Chart Resource**: The program declares a `Chart` resource named `ara` using the `@pulumi/kubernetes/helm` module, specifying the chart name, along with any required deployment values. You would typically specify which namespace the chart should be deployed into as part of the helm chart options. If `ara` requires custom configuration, it should be passed in the `values` object.

3. **Export Output**: Finally, the program can export any relevant outputs that you might need, such as the status of the helm deployment.

Here is the Pulumi TypeScript program:

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

// The detailed explanation for the code begins here:

// We create a new instance of the Chart class from the pulumi/kubernetes/helm module,
// specifying the release name ("ara"), and options which contain the chart details.
// We set the chart version to a specific version required for the ara chart.
// The `repo` option specifies the Helm chart repository.
// If the 'ara' Helm chart requires specific `values` for configuration, you would add them in the `values` object.
// The namespace is where this helm chart will be deployed. Replace 'YOUR_NAMESPACE' with your actual namespace.

const araChart = new k8s.helm.v3.Chart("ara", {
    chart: "ara",
    version: "x.y.z", // Replace with the specific chart version you require
    namespace: "YOUR_NAMESPACE", // Specify the namespace where the chart should be installed
    // Add the Helm repo URL that contains the 'ara' chart if it's not from the stable repository
    // Example:
    // repo: "https://charts.example.com/repository",
    // values: {
    // Here you could provide configuration options that are specific to the ara Helm chart.
    // For example:
    // someValue: someSetting,
    // },
});

// This line exports the status of the Helm release which includes various properties such as the version,
// and the namespace where it has been deployed. You may view these details in your Pulumi stack output.
export const araHelmDeploymentStatus = araChart.status;

// Now that the code has completed, you have a Pulumi program that will deploy the `ara` Helm chart to your OpenShift Cluster.
// You must have your Pulumi CLI set up and configured along with access to an OpenShift cluster for this code to work.
```

To deploy the chart, make sure you've Pulumi CLI installed and configured along with access to your OpenShift cluster. Save this program to a file (e.g., `index.ts`), then run `pulumi up` to execute the deployment.

Please replace `"x.y.z"` with the specific version of the `ara` helm chart you intend to deploy, `"YOUR_NAMESPACE"` with the target namespace in your OpenShift cluster, and the `values` as per the chart's requirements. If `ara` is not in the default helm repository, amend the `repo` key with the URL of the repository containing the `ara` chart.

Remember to use `pulumi destroy` if you need to delete the deployed resources later, and to check the Pulumi documentation for any additional details or configuration options that might be relevant to your use case.
