Deploy the trino-exporter helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `trino-exporter` Helm chart on Kubernetes using Pulumi, you need to have a Kubernetes cluster configured and accessible from your machine where Pulumi is installed. You also need to have Helm and Pulumi installed on your local development machine.

The following Pulumi program in TypeScript will deploy a Helm chart to a Kubernetes cluster. It assumes that the `trino-exporter` Helm chart is available in a Helm repository, and that you have access to this repository.

Here's a step-by-step guide before we dive into the code:

1. **Create a new Pulumi project**: If you haven't done so already, you'll need to create a new Pulumi project which will organize your infrastructure resource definitions.

2. **Add the correct provider**: Make sure the Kubernetes provider is added to your project. This will allow Pulumi to interact with your Kubernetes cluster.

3. **Define the Helm Chart**: You'll need to specify the details of the `trino-exporter` Helm chart such as the `repo` (the Helm repository where the chart is located), `chart` (the name of the chart, in this case, `trino-exporter`), and `version` (the specific version of the chart you want to deploy).

4. **Deploy the Helm Chart**: Finally, you'll deploy the chart to your Kubernetes cluster using Pulumi.

Let's look at the actual Pulumi code for deploying the `trino-exporter` Helm chart:

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

// You should replace the following values with the actual details of your Helm chart.
const helmRepoName = "trino-exporter-repo"; // The name of the Helm repository
const helmRepoUrl = "http://your-helm-repository.org/"; // The URL of the Helm repository
const chartVersion = "1.0.0"; // The desired chart version

// Create a Chart resource to deploy a Helm chart.
const trinoExporterChart = new k8s.helm.v3.Chart("trino-exporter", {
    repo: helmRepoName,     // specify the name of the Helm repo
    chart: "trino-exporter",  // specify the name of the chart
    version: chartVersion,   // specify the chart version
    // In case you need to customize chart values, specify them here, e.g.:
    // values: {
    //     key: "value",
    // },
}, {
    // Custom resource options (uncomment if needed):
    // dependsOn: [ /* dependencies */ ],
    // providers: { kubernetes: k8sProvider },
});

// Export the name of the chart.
export const chartName = trinoExporterChart.metadata.name;

// Additional outputs can be defined here if required.
```

In the code provided above:

- We import the Kubernetes package from Pulumi which provides the capabilities to deploy to Kubernetes clusters.
- We specify the details of the Helm chart, like the repository URL, the chart name, and version. Make sure to replace the placeholders with the actual details of the Helm repository where the `trino-exporter` chart is located.
- We create an instance of `Chart` from the `@pulumi/kubernetes/helm/v3` module. This represents the deployment of the Helm chart to your Kubernetes cluster.
- We optionally export the name of the chart so that you can easily identify the deployed resources.

To run this Pulumi program:

1. Save this code to a file with a `.ts` extension.
2. Make sure you have access to a Kubernetes cluster and that your `kubeconfig` is set up correctly.
3. Run `pulumi up` from your command line within the directory where your Pulumi program is saved.

Pulumi will prompt you for confirmation before making any changes to your infrastructure. After confirming, it will deploy the `trino-exporter` helm chart to your Kubernetes cluster.
