Deploy the tyk-bootstrap helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Kubernetes using Pulumi is straightforward. Below, I'll walk you through the steps to deploy the tyk-bootstrap Helm chart on a Kubernetes cluster. We'll be using the kubernetes.helm.v3.Chart resource which is a part of the @pulumi/kubernetes package. This resource is a high-level component that deploys a Helm chart as a part of your Pulumi application.

Before you begin, make sure you have access to a Kubernetes cluster and your Kubernetes configuration is appropriately set, as Pulumi uses the cluster credentials configured in your environment. Also, ensure that you have Pulumi installed and set up along with the @pulumi/kubernetes package.

Here's what the program will do:

Import necessary packages for your Pulumi app.
Deploy the tyk-bootstrap Helm chart from the Helm repository where the chart is published.

Now, let's write the program:

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

// Create a Helm Chart for Tyk-Bootstrap.
// Note: Ensure that you provide the proper helm repo or local path where your chart is located.
const tykBootstrapChart = new k8s.helm.v3.Chart("tyk-bootstrap", {
    chart: "tyk-bootstrap",
    version: "<ENTER_CHART_VERSION>", // Specify the chart version you want to deploy
    fetchOpts: {
        repo: "https://helm.tyk.io/public/helm/charts/", // Official Tyk Helm repo URL
    },
    // Values from the Helm chart's 'values.yaml' may be provided here.
    // These values will override the default values of the chart.
    values: {
        // Example of value override
        // namespaces: {
        //     tyk: "tyk-system-namespace",
        // },
    },
});

// Export the resources created.
export const chartName = tykBootstrapChart.metadata.name;

Understanding the code:

@pulumi/kubernetes: It's the core Pulumi Kubernetes package that provides a way to interact with Kubernetes resources.
k8s.helm.v3.Chart: With this resource, we deploy the tyk-bootstrap chart.
chart: This is the name of the chart we want to deploy.
version: Here you need to replace <ENTER_CHART_VERSION> with the version of the chart you wish to deploy.
repo: This is the Helm repository URL where the tyk-bootstrap chart is hosted; we're using the official Tyk repository.
values: This is an optional parameter where you can provide any values you want to override in the chart's values.yaml file. If you don't specify any values, the defaults defined in the chart will be used.

After you've written this Pulumi program, running pulumi up in your command line will initiate the deployment process. Pulumi will show you a preview of the resources that will be created, and upon confirmation, it will proceed with creating the resources on your Kubernetes cluster.

Remember to substitute <ENTER_CHART_VERSION> with the actual version of the Tyk bootstrap chart you want to deploy. You can also provide additional configurations in the values field as needed.

If you have any place-specific configuration or need to organize resources in namespaces, ensure you update the values section accordingly based on the values.yaml of the specific Helm chart version you use.
