Deploy the provider-aws helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

In order to deploy the `provider-aws` Helm chart on a Linode Kubernetes Engine (LKE) instance using Pulumi, you would need to do the following:

1. Set up a Linode Kubernetes Engine cluster.
2. Configure your Pulumi environment for the Linode provider and the Kubernetes provider.
3. Use the Pulumi Kubernetes provider to deploy the `provider-aws` Helm chart to the LKE cluster.

Below is a program in TypeScript that demonstrates how to accomplish this. Do note that `provider-aws` is not an actual Helm chart, so for this example, I will assume you want to deploy a generic Helm chart from a repository. The example will also assume you've already created an LKE cluster and have its kubeconfig file available. In a real-world scenario, you may need to replace `"generic-chart"` and `"generic-repo"` with the actual chart and repository names for AWS.

First, we need to install the necessary Pulumi packages for Linode and Kubernetes. You can do this by running `npm install` with the following packages:

```bash
npm install @pulumi/linode @pulumi/kubernetes
```

Now let's proceed with the Pulumi program:

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

// Load the kubeconfig file from local file path to connect to the LKE cluster
const kubeconfig = "./kubeconfig.yaml";

// Create a Kubernetes provider instance using the kubeconfig from Linode Kubernetes Engine
const provider = new kubernetes.Provider("lke-k8s", {
    kubeconfig: kubeconfig,
});

// Deploy the 'provider-aws' Helm chart into the LKE cluster
const chartName = "provider-aws"; // This should be the actual chart name for AWS
const repoName = "aws"; // The actual repository name that hosts the AWS chart
const chart = new kubernetes.helm.v3.Chart("aws-helm-chart", {
    chart: chartName,
    version: "1.0.0", // Specify the chart version you want to deploy
    repo: repoName,
    namespace: "default", // Specify the Kubernetes namespace to deploy into
    // You can provide additional configuration for the Helm chart here with `values`
}, { provider });

// Export the public IP address of the service once it's deployed
export const serviceIp = chart.getResourceProperty("v1/Service", "my-service", "status").apply(status => status.loadBalancer.ingress[0].ip);

```

This program will use the Pulumi Kubernetes provider to deploy a Helm chart assumed to be named `provider-aws` in the `default` namespace on a Linode Kubernetes Engine cluster. The `kubeconfig` file needs to be at the location specified in the program, or you can modify the path as per your setup.

The `serviceIp` export assumes that the deployed Helm chart results in a `Service` object called `my-service`. In practice, you will need to replace `my-service` with the actual name of the service deployed by the Helm chart.

Before running this Pulumi program, ensure you have the kubeconfig file for your LKE cluster, have the Pulumi CLI installed, and have logged into your Linode account. Also, make sure to replace any placeholder values with actual values that match your requirements and the Helm chart you intend to deploy.
