Deploy the rate-limit-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `rate-limit-operator` Helm chart on OpenShift using Pulumi, you will first need to set up the necessary prerequisites:

1. OpenShift cluster: Ensure that you have access to an OpenShift cluster and the `oc` CLI is configured to interact with your cluster.
2. Helm chart: The `rate-limit-operator` Helm chart must be available in a Helm repository or as a local chart.
3. Pulumi: Make sure you have Pulumi installed and configured for TypeScript projects.

Given these prerequisites are met, you can proceed with the Pulumi program to deploy the Helm chart.

We'll use the `kubernetes.helm.v3.Chart` class from the Pulumi Kubernetes provider to deploy the Helm chart. This class can deploy charts from any Helm chart repository or local Helm chart.

Here's the Pulumi program in TypeScript that would handle the deployment:

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

// Define the configuration for the rate-limit-operator Helm chart.
const rateLimitOperatorChart = new k8s.helm.v3.Chart("rate-limit-operator", {
    // Replace 'CHART_REPO_URL' with the URL of the repository containing the chart.
    // Ensure that this repository is added to your Helm repositories, otherwise,
    // specify the local path where the chart is located.
    repo: "CHART_REPO_URL", // Example: "https://my-helm-repo.org/charts"
    chart: "rate-limit-operator",
    // Specify the chart version you wish to deploy.
    version: "CHART_VERSION", // Example: "1.2.3"
    // Define values to override the default chart values.
    // Refer to the Helm chart's 'values.yaml' for the list of possible values.
    values: {
        // Example values override:
        // replicaCount: 2,
        // customValue: "example",
    },
    // This is the namespace for the rate-limit-operator. Change if needed.
    namespace: "default",
});

// Export the resources created by the chart if needed.
export const chartResources = rateLimitOperatorChart.resources;
```

In the above code:

- Replace `CHART_REPO_URL` with the actual URL of the repository that hosts the `rate-limit-operator` Helm chart.
- Replace `CHART_VERSION` with the version number of the chart you wish to install. If you want to install the latest version, you can omit the `version` field.
- Customize the `values` field with any specific configuration you need for the `rate-limit-operator`. These values will override the defaults in the chart's `values.yaml` file.

Once you have configured the code above with the correct chart repository and version, running `pulumi up` will deploy the specified chart to your OpenShift cluster.

Please note that deploying to OpenShift might require additional configurations due to specific OpenShift security contexts or permissions. If you face any issues related to permissions or security contexts, you may need to adjust the chart's values or OpenShift project settings accordingly.
