Deploy the tsorage helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

In order to deploy a Helm chart to a Kubernetes cluster managed by Linode Kubernetes Engine (LKE), you'll utilize Pulumi's Kubernetes provider to interact with your cluster and deploy applications using Helm charts. In this example, I assume that you already have an LKE cluster up and running and that you have the necessary kubeconfig to access it.

We'll accomplish this in the following steps:

Set up the Pulumi Kubernetes provider to communicate with your LKE cluster.
Use the Chart resource from the @pulumi/kubernetes/helm/v3 module to deploy the "tsorage" Helm chart to your cluster.

Here's how you can do it in TypeScript:

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

// Step 1: Create a Kubernetes provider instance using credentials from kubeconfig
const provider = new k8s.Provider("lke-provider", {
    kubeconfig: "<your-kubeconfig>", // Make sure this is the path to your LKE cluster kubeconfig
});

// Step 2: Deploy the "tsorage" Helm chart using the Pulumi Kubernetes Helm Chart resource
const tsorageRelease = new k8s.helm.v3.Chart("tsorage", {
    chart: "tsorage",
    // You may need to provide the repo URL where the "tsorage" chart can be found, like this:
    // repo: "http://<helm-chart-repository-url>",
    version: "<chart-version>", // Specify the chart version you want to deploy
    namespace: "default", // Specify the namespace where you want the chart to be deployed
}, { provider });

// Optional: Export a property from the Chart resource, like the status of the deployment
export const tsorageStatus = tsorageRelease.status;

In the code above:

Replace <your-kubeconfig> with the actual kubeconfig content or file path of your LKE cluster. The kubeconfig is needed for Pulumi to authenticate with your Kubernetes cluster.
Replace <chart-version> with the specific version of the tsorage chart that you want to deploy. If you don't specify a version, it will use the latest version available.
The namespace field is optional and defaults to default. You can set it to whatever namespace you'd prefer to deploy your chart into.

Note: It is important that you replace the placeholders with actual values suitable for your deployment. For example, if the tsorage chart is hosted in a specific Helm repository, you must provide the URL of the repository to the repo property.

The k8s.helm.v3.Chart resource is a high-level component that encapsulates the deployment of Helm charts in Kubernetes via Pulumi. When this Pulumi program is run, it will interact with the Kubernetes cluster referred to by the kubeconfig and deploy the tsorage Helm chart.

Make sure that you have installed Pulumi CLI, and configured access to your Linode account and Kubernetes cluster. You should be able to run this TypeScript program using Pulumi after setting up your Pulumi project and stack.
