Deploy the supertubes helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `supertubes` Helm chart on Kubernetes using Pulumi, you need to perform a few steps:

1. Set up your Pulumi project and ensure you have access to a Kubernetes cluster.
2. Use the Pulumi Kubernetes package to create a Helm chart resource in your Pulumi program.
3. Configure the Helm chart properties, such as its name, version, and values per your requirements.

Below is a detailed Pulumi program in TypeScript that demonstrates how to deploy the `supertubes` Helm chart on Kubernetes. Ensure that you have the Pulumi CLI installed and configured for your Kubernetes cluster.

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

// Create an instance of the Helm chart.
// You must have your Kubernetes context set up to point to the desired cluster
// where the chart will be deployed.
const supertubesChart = new k8s.helm.v3.Chart("supertubes", {
    // Replace with your chart name, repository, and version as applicable
    chart: "supertubes",
    version: "x.y.z", // specify the exact version you need
    fetchOpts: {
        // Depending on where your chart is hosted, you may need to specify repository options.
        // If your chart is part of an existing repository, ensure to add that repo to Helm locally
        // with `helm repo add` or provide these details as part of fetchOpts.
        repo: "https://your-helm-chart-repository/",
    },
    // Values to pass to the Helm chart.
    // Here you can specify the configurations that your chart requires.
    values: {
        key1: "value1",
        key2: "value2",
        // Add additional configuration values here
    },
});

// Optional: Export the Helm chart name and the Kubernetes namespace it is deployed into
export const chartName = supertubesChart.metadata.name;
export const namespace = supertubesChart.metadata.namespace;
```

### Explanation:

- **Importing the Kubernetes module**: We import the `@pulumi/kubernetes` package, which allows us to interact with Kubernetes resources within our Pulumi program.

- **Creating the Helm Chart resource**: We create a new `Chart` resource using `new k8s.helm.v3.Chart()`. The `supertubes` string is an arbitrary name given to the Helm chart we are deploying.

- **Chart properties**: In the `Chart` resource definition, you need to specify the `chart`, `version`, and `fetchOpts.repo`. Replace `"supertubes"` with the actual chart name you want to deploy. Provide the version you want to use in place of `"x.y.z"`. Also, update the `repo` URL to point to the repository where your Helm chart is located.

- **Values configuration**: The `values` field is a JavaScript object containing the configuration values for the Helm chart. Replace `key1`, `key2`, `value1`, and `value2` with the actual configuration keys and values needed by your `supertubes` chart.

- **Exports**: Optionally, the program exports the Helm chart name and namespace to access them from outside of the Pulumi program if needed.

Make sure you have your Kubernetes configuration context set correctly so that Pulumi uses the right cluster for deploying the Helm chart.

Finally, run your Pulumi program with the following commands:

```bash
pulumi up
```

This command will prompt you to review the changes before applying them. Once you confirm, Pulumi will deploy the specified Helm chart with your defined configurations onto the Kubernetes cluster.
