Deploy the ark helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the "ark" Helm chart on a Kubernetes cluster using Pulumi, you'll use the `Chart` resource from Pulumi's Kubernetes provider. The `Chart` resource allows you to deploy a Helm chart from a repository or a local path. Helm is a package manager for Kubernetes that packages multiple Kubernetes resources into a single logical deployment unit called a "chart".

To begin deploying the ark Helm Chart, first you need to ensure that you have a Kubernetes cluster running and that your `kubectl` is configured to communicate with it. This configuration is typically found in `~/.kube/config` and is used by Pulumi's Kubernetes provider to deploy resources to the correct cluster.

For this deployment, you'll need to specify the repository URL where the ark chart can be found, and the version of the chart you want to install. You can also provide custom values to the chart by creating a YAML file with your configurations and passing its contents to the `values` field in the options.

Below is a complete Pulumi program written in TypeScript that deploys the ark Helm chart:

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

// Define the ark Helm chart from a remote repository
const arkChart = new k8s.helm.v3.Chart("ark", {
    // Replace with the actual repository URL and version that hosts the ark chart
    repo: "example-repo",
    chart: "ark",
    version: "1.0.0", // Replace with the desired chart version
    // If additional configuration is required, use the 'values' option:
    // values: {
    //    key1: value1,
    //    key2: value2,
    // },
});

// Export the ark Chart deployment name
export const arkChartName = arkChart.metadata.apply(m => m.name);
```

In this program, you create a new instance of `k8s.helm.v3.Chart` to deploy the ark Helm chart:

- The `repo` is set to a placeholder string `"example-repo"`. You'll need to replace it with the actual URL of the repository where the ark Helm chart is hosted.
- The `chart` is specified as `"ark"`, which is the name of the chart in the repository.
- The `version` field specifies the version of the chart to deploy. Replace `"1.0.0"` with the version you need.
- The `values` field supplies any override values needed for customizing the deployment. This field accepts an object representing the values.yaml file that you would typically use with Helm on the command line.

To apply this Pulumi program:

1. Ensure you have Pulumi installed and have set up your Pulumi project.
2. Have your Kubernetes cluster running and `kubectl` configured.
3. Replace the placeholder values in the `repo` and `version` fields with actual values corresponding to the ark Helm chart you'd like to deploy.
4. If necessary, add a `values` field with an object that contains any required configuration for your ark chart deployment.
5. Run `pulumi up` to preview and deploy the changes.

When you run the `pulumi up` command, Pulumi will communicate with your Kubernetes cluster and deploy the ark Helm chart specified in the program. If successful, you will see output indicating the resources that were created. The exported `arkChartName` provides the name of the ark Chart deployment, which you can use to reference and manage it in future Pulumi updates or inquire about its status using `kubectl`.
