Deploy the fluentbit-resource helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `fluentbit` Helm chart on an OpenShift cluster using Pulumi, you will be creating a Pulumi program in TypeScript that leverages the Kubernetes provider. The Kubernetes provider in Pulumi allows you to interact with your Kubernetes cluster and deploy applications using Helm charts.

First, you should have Pulumi installed along with the necessary cloud provider CLI (in this case OpenShift's `oc` or `kubectl` for Kubernetes). Ensure you are authenticated to your OpenShift cluster to which you wish to deploy the Helm chart.

The Pulumi program will involve the following steps:
1. Importing necessary packages.
2. Creating a Helm chart resource using `@pulumi/kubernetes`.
3. Setting chart values if needed.

Here’s how you can create a Pulumi program to deploy the `fluentbit` Helm chart on OpenShift:

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

// Create an instance of Helm Chart for fluentbit.
const fluentbitChart = new k8s.helm.v3.Chart("fluentbit-resource", {
    // You need to specify the chart and repository details
    // for fluentbit alongside any custom values.
    // For fluent-bit this configuration may require customization as per your cluster specifics.
    chart: "fluentbit",
    version: "X.Y.Z", // Specify the version of the chart
    fetchOpts: {
        repo: "https://fluent.github.io/helm-charts",
    },
    // Values for the Helm chart as per the requirements.
    // Refer to the Helm chart documentation for `fluentbit`
    // to understand what values are needed. This is an example configuration.
    values: {
        // Your custom configuration here:
    },
    // Assuming deployment to 'logging' namespace. Create the namespace if not exists.
    namespace: "logging", 
}, { provider: openshiftProvider }); // Pass the appropriate provider if needed.

// Export the base URL
// If the chart exposes any endpoints, you may need to export such information.
export const fluentbitBaseUrl = fluentbitChart.getResourceProperty("v1/Service", "fluentbit", "status");
```

What you need to customize in the above code:
- Ensure to specify the actual `version` of the fluentbit chart you want to deploy.
- Customize the `values` to match the fluentbit configuration required for your infrastructure or application.
- Assign `openshiftProvider` which should be configured to point to your OpenShift cluster if using a provider configuration. If you are using the default provider (kubeconfig) and it's already set for your OpenShift, you might not need to pass this argument.

After you write your Pulumi TypeScript program, you should [install the Pulumi CLI](https://www.pulumi.com/docs/get-started/install/) and run:

```sh
pulumi up
```

To deploy the changes to your OpenShift cluster. The `pulumi up` command will show you a preview of what resources will be created or changed. If you agree with the changes, select `yes` to proceed with the deployment.

Please make sure to replace the "X.Y.Z" with the actual chart version you intend to deploy and to review and provide the correct values that are tailored to your needs. The `fluentbit` chart provided in this example is sourced from its [official Helm repository](https://fluent.github.io/helm-charts), ensure that it contains the `fluentbit` chart or refer to its documentation for the correct repository URL.
