Deploy the logstash-super-turbo helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the `logstash-super-turbo` Helm chart on Rancher using Pulumi, we're going to use the `rancher2` package. This provider allows you to manage Rancher 2 resources programmatically.

In this program, we'll create a new Rancher 2 catalog, then deploy the `logstash-super-turbo` Helm chart into a specific project and namespace within a Rancher managed Kubernetes cluster. We'll assume that you have already installed Rancher, configured it correctly, and have access to its API from Pulumi.

Here's a step-by-step Pulumi program in TypeScript:

1. Set up the `rancher2` provider using the API token and URL of your Rancher server.
2. Create a new catalog if needed, or use an existing one with the Helm chart repository that contains the `logstash-super-turbo` chart.
3. Create a namespace in a specific project where we want to deploy the Helm chart.
4. Finally, deploy the Helm chart using the details such as chart name, version, values, and so on.

Below is the complete program:

```typescript
import * as rancher2 from "@pulumi/rancher2";
import { CatalogV2, AppV2 } from "@pulumi/rancher2";

// Initialize Rancher 2 provider with the required credentials.
// You have to replace `RANCHER_API_URL` and `RANCHER_API_TOKEN` with actual values.
const rancherProvider = new rancher2.Provider("rancherProvider", {
    apiUrl: "RANCHER_API_URL",
    apiToken: "RANCHER_API_TOKEN",
});

// Optional: Create a new Rancher Catalog (if it does not already exist)
// This is usually a one-time setup step and may not be needed in your case.
const catalog = new CatalogV2("logstashCatalog", {
    clusterId: "local",
    url: "https://logstash-helm-chart-repo.example.com", // Replace with the URL of the Helm chart repository
    branch: "main",
}, { provider: rancherProvider });

// Apply the Rancher Catalog to create it.
catalog.apply(c => {
    const logstashChartVersion = "1.0.0"; // Replace with the version of the chart you want to deploy.

// Create a namespace in a specific project within the Rancher cluster.
    // Replace `YOUR_PROJECT_ID` and `YOUR_NAMESPACE` with actual values.
    const namespace = new rancher2.Namespace("logstashNamespace", {
        projectId: "YOUR_PROJECT_ID", // The Project ID where the namespace and app will reside
        name: "YOUR_NAMESPACE", // The name of the namespace where you want to deploy your app
    }, { provider: rancherProvider });

// Deploy the `logstash-super-turbo` Helm chart into the specified namespace.
    const logstashApp = new AppV2("logstashApp", {
        // Chart details and deployment configuration
        chartName: "logstash-super-turbo",
        chartVersion: logstashChartVersion,
        clusterId: "local",
        projectId: namespace.projectId,
        namespace: namespace.name,
        // Assume we have default values or have a custom values file that you want to deploy with your app.
        values: `
logstashConfig:
  key1: value1
  key2: value2
`,
    }, { provider: rancherProvider });

return logstashApp;
});

// Export the endpoint of logstash application if it has one
export const logstashEndpoint = logstashApp.status.apply(status => status.endpoint);
```

In this program, replace `RANCHER_API_URL`, `RANCHER_API_TOKEN`, `YOUR_PROJECT_ID`, and `YOUR_NAMESPACE` with the actual values specific to your Rancher setup. The values YAML string should contain the custom configurations you want to apply to your Logstash deployment; replace `key1: value1` and `key2: value2` with actual Logstash configurations.

Please ensure you have Rancher 2 credentials and access to the Rancher 2 cluster where you want to deploy the Helm chart. To use the presented code, you need to have Pulumi CLI and Node.js installed on your machine. Save the code in a `index.ts` file, run `npm install` to fetch the necessary packages, and then use `pulumi up` to deploy your resources.
