Deploy the tt-workflow-driver helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

Deploying a Helm chart on the Linode Kubernetes Engine (LKE) using Pulumi is simple. You'll use the kubernetes.helm.v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart within a Kubernetes cluster. The Chart resource accepts parameters such as the name of the chart, the Helm repository where the chart can be found, and custom value overrides that you may wish to provide.

To deploy the tt-workflow-driver Helm chart on LKE, you'll need to ensure that you have a Kubernetes cluster running on Linode. Assuming you have already set up an LKE cluster and configured kubectl and Pulumi to interact with it, below is how you can deploy the Helm chart using Pulumi with TypeScript.

First, you should import the necessary modules and set up the main logic required for a Pulumi program:

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

// Deploy a Helm chart `tt-workflow-driver` on Linode Kubernetes Engine.
const chart = new k8s.helm.v3.Chart("tt-workflow-driver", {
    chart: "tt-workflow-driver",
    // Assuming the Helm chart is in a repository that Pulumi should fetch.
    fetchOpts: {
       // Here is where you would specify the repository options if needed.
       // For instance, you could specify `repo: "http://<helm-chart-repository>/"`,
       // if your Helm chart is hosted in a custom repository.
    },
    // Here you can provide any custom values to the Helm chart.
    // This is how you would customize the deployment to your needs.
    // values: {
    //   service: {
    //     type: "ClusterIP"
    //   }
    // },
    // If your Helm chart has dependencies on other charts,
    // or needs to pull in images from private repositories,
    // you can set these configurations here as well.
});

This code creates a new instance of a Helm chart deployment within your LKE cluster. The Chart object takes in the chart name (tt-workflow-driver), and it can also take in additional configuration options like fetching options (fetchOpts) and chart values (values) which can be specified to tailor the deployment to your requirements.

Remember to replace placeholders like <helm-chart-repository> with the actual URL to the Helm chart repository where the tt-workflow-driver chart can be found if it’s not in the default Helm repository.

To run this program:

Ensure you have Pulumi installed and configured with your LKE credentials.
Save the above code to a file (e.g., index.ts)
Run pulumi up to preview and deploy the changes to your cluster.

After running the program, Pulumi will perform the deployment, and you will end up with the tt-workflow-driver Helm chart running on your Linode Kubernetes Engine cluster. Pulumi will provide you with an output that shows what resources will be created or modified. After reviewing the changes, you can confirm the deployment, and Pulumi will manage the deployment process for you.
