1. Deploy the tyk-operator helm chart on Linode Kubernetes Engine


    If you're looking to deploy the tyk-operator Helm chart on Linode Kubernetes Engine (LKE), you'll first need to ensure that you have an LKE cluster up and running. Once you have your Kubernetes cluster, you can use Pulumi's Kubernetes provider to deploy the tyk-operator Helm chart.

    The following Pulumi TypeScript program demonstrates how to deploy a Helm chart to a Kubernetes cluster. This program assumes that you've already set up and configured kubectl to interact with your Linode Kubernetes cluster and have installed pulumi CLI. It leverages the @pulumi/kubernetes package to apply a Helm chart directly.

    First, let's go through some of the resources and their purpose:

    • @pulumi/kubernetes: This is the Pulumi Kubernetes provider that allows us to work with Kubernetes resources, including deploying Helm charts.
    • helm.v3.Chart: This Pulumi resource is used to deploy a Helm chart. In our case, it will be used to deploy the tyk-operator chart.

    The program below is structured in the following way:

    1. Import necessary Pulumi and Kubernetes packages.
    2. Define the configuration for the Helm chart, such as the name, version, and any specific values you want to override in the chart.
    3. Deploy the Helm chart using the Chart resource.

    Let's take a look at the code. Please replace <YOUR-NAMESPACE> with the namespace where you want to deploy the Tyk Operator.

    import * as k8s from "@pulumi/kubernetes"; // Define the settings for the tyk-operator Helm chart. const tykOperatorChart = new k8s.helm.v3.Chart("tyk-operator", { chart: "tyk-operator", version: "0.9.1", // Specify the version of the chart you want to deploy. namespace: "<YOUR-NAMESPACE>", // Replace with your target namespace. fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // Helm repository containing the tyk-operator chart. }, // Define any additional values you want to pass to the Helm chart. values: { installCRDs: true, // As an example, we ensure CRDs are installed by the chart. // Add other values as required for your configuration. }, }); // Export the name of the namespace that tyk-operator was deployed into. export const namespaceName = tykOperatorChart.namespace;

    To clarify a few of the steps in the code:

    • We create a new Helm chart resource using new k8s.helm.v3.Chart. The properties passed to the constructor define how the Helm chart should be deployed.
    • The chart parameter specifies the name of the Helm chart we want to deploy.
    • The version parameter should match the version of the tyk-operator chart you wish to deploy.
    • The namespace parameter is where the Tyk Operator will be installed. You should replace <YOUR-NAMESPACE> with the actual namespace you plan to use.
    • The fetchOpts.repo parameter specifies the repository where the Helm chart is located.
    • The values parameter is a dictionary where you can specify any custom values for your Helm chart that overrides the default settings.

    To apply this Pulumi program, save the code to a file with a .ts extension, make sure you are authenticated to your LKE cluster, and then run the following commands:

    pulumi stack init tyk-operator-deployment pulumi up

    Pulumi will perform the deployment, and you'll be able to track the progress and status in your terminal. Once the deployment is successful, the Tyk Operator will be running on your LKE cluster.
