Deploy the elastic-filebeat helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Elastic Filebeat Helm chart on OpenShift using Pulumi, you'll first need to ensure you have an OpenShift cluster up and running. Pulumi's Kubernetes package can then be used to deploy Helm charts to your cluster.

Below is a Pulumi program written in TypeScript that demonstrates how to deploy the Elastic Filebeat Helm chart to an OpenShift cluster. The program uses the `Chart` resource from Pulumi's Kubernetes package, which encapsulates a Helm chart deployment.

Before diving into the code, here's a step-by-step explanation:

1. Import necessary Pulumi and Kubernetes packages.
2. Create a Kubernetes provider instance that targets your OpenShift cluster.
3. Use the `Chart` class from the `@pulumi/kubernetes/helm/v3` package to create a new Helm chart deployment in your cluster.
   - The `repo` argument specifies the Helm repository containing the chart.
   - The `chart` argument specifies the name of the chart to deploy.
   - The `version` argument can optionally specify a specific chart version.
   - The `values` argument allows you to provide configuration values that will be passed to the Helm chart upon deployment.

Make sure you have set up the `kubeconfig` file correctly so that Pulumi can communicate with your OpenShift cluster.

Now, here's the Pulumi TypeScript program:

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

// Initialize a Kubernetes provider with the context of your OpenShift cluster.
const k8sProvider = new kubernetes.Provider("openshift-provider", {
    // You can specify a kubeconfig file or other configuration here that provides access to your OpenShift cluster.
});

// Deploy the Elastic Filebeat Helm chart.
const filebeatChart = new kubernetes.helm.v3.Chart("filebeat", {
    // Define the Helm chart details.
    repo: "elastic",
    chart: "filebeat",
    // Optionally specify the version of the chart.
    // version: "x.y.z",
    // Provide any custom values to the Helm chart.
    values: {
        // Custom values for the Filebeat Helm chart can be specified here.
        // For example:
        // filebeatConfig: {
        //   filebeat.yml: "...",
        // },
    },
}, { provider: k8sProvider });

// Export the Helm release status and other details if necessary.
export const filebeatReleaseName = filebeatChart.getResourceProperty("v1/Service", "filebeat-filebeat", "metadata").name;
export const filebeatReleaseNamespace = filebeatChart.getResourceProperty("v1/Service", "filebeat-filebeat", "metadata").namespace;
```

To apply this program, perform the following steps:
1. Save the code in a file (e.g., `index.ts`).
2. Run `pulumi up` to preview and deploy the changes.

By executing the `pulumi up` command, Pulumi will communicate with your OpenShift cluster, deploy the specified Helm chart, and output the service name and namespace where the Filebeat application is running.

Please note that the actual `values` to provide will depend on your specific use case and configuration requirements for Filebeat. You would typically provide these values in the Helm chart to specify Elasticsearch connection details and other configuration parameters for Filebeat.
