Deploy the rafay-operator-redhat helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `rafay-operator-redhat` Helm chart on an OpenShift cluster using Pulumi, you'll need to have access to an OpenShift cluster where you have permissions to deploy applications. In this guide, we'll assume you've already provisioned an OpenShift cluster and have configured your `kubectl` to interact with it.

We will use the `kubernetes` package provided by Pulumi, which enables us to work with Kubernetes resources, including managing Helm charts. The `kubernetes.helm.v3.Chart` resource allows us to deploy Helm charts into a Kubernetes cluster.

Here's a step-by-step Pulumi TypeScript program that deploys the `rafay-operator-redhat` Helm chart:

1. First, ensure you have installed Pulumi and set up your OpenShift cluster.
2. Next, create a new directory for your Pulumi project and switch to it.
3. Run `pulumi new typescript` to create a new Pulumi TypeScript project.
4. Install the necessary Pulumi Kubernetes package by running `npm install @pulumi/kubernetes`.

Now we're ready to define the Pulumi program:

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

// Replace with the namespace where you want to deploy the chart, if different from `default`.
const namespace = 'default';

// Helm Chart version, can be a specific version or `null` to get the latest
const chartVersion = 'x.y.z';

// Helm Chart values can be provided as an object.
const chartValues = {
    // Specify the chart values here, for example:
    // replicaCount: 2
    // image: {...}
};

// Instantiate the Helm chart for the rafay-operator-redhat chart from its repository.
const rafayOperatorChart = new k8s.helm.v3.Chart('rafay-operator-redhat', {
    chart: 'rafay-operator-redhat',
    version: chartVersion,
    fetchOpts: { 
        repo: 'https://charts.rafay.co/rcc', // This is a placeholder, replace with the Rafay Helm chart repository if different
    },
    values: chartValues,
    namespace: namespace,
}, {
    dependsOn: [], // If there are specific resources this chart depends on, list them here
});

// Optional: Export the Helm release status
export const helmReleaseStatus = rafayOperatorChart.status;
```

This program sets up the deployment of the `rafay-operator-redhat` Helm chart to your OpenShift cluster. The `chartValues` object is where you can specify the customizable values you want to use for the Helm chart. You need to replace the placeholder URL I've put in the `repo` property of `fetchOpts` with the actual repository URL where the Rafay Helm chart is located.

You should replace the `chartVersion` with the version of the Rafay operator that you wish to deploy if you have a specific version in mind. Otherwise, setting it to `null` will pull the latest version of the chart.

In your OpenShift cluster, you may need to work with specific permissions or ServiceAccounts, depending on your cluster's role-based access control (RBAC) setup. Ensure you apply appropriate configurations that comply with your cluster's RBAC policies.

To apply this Pulumi program:

1. Run `pulumi up` to preview and deploy the changes.
2. Review the planned changes and select `yes` to confirm and deploy the chart to your OpenShift cluster.

After the deployment succeeds, you should be able to see the Rafay operator running in the specified namespace by using `kubectl get pods -n <namespace>`.

Remember that Helm charts are typically maintained by their providers, so refer to the chart's documentation for configuration details and requirements specific to the `rafay-operator-redhat` chart.
