1. Deploy the tyk-operator helm chart on Opensshift


    To deploy a Helm chart on a Kubernetes cluster using Pulumi, you can use the helm.sh/v3.Chart resource from the Pulumi Kubernetes provider. This resource allows you to deploy Helm charts in a declarative way, specifying the chart name, values, and other configuration options.

    For deploying on OpenShift, which is a Kubernetes distribution, you can follow the same process as you would for a standard Kubernetes cluster. However, OpenShift has some additional security and networking features that you might need to account for, depending on the Helm chart requirements and your OpenShift cluster configuration.

    Below is a Pulumi TypeScript program that deploys the tyk-operator Helm chart to an OpenShift cluster. This program assumes that you already have access to an OpenShift cluster and that you've configured Pulumi to communicate with this cluster using your kubeconfig file.

    First, we will install the necessary Pulumi packages for Kubernetes and then create a new Pulumi program.

    Here is the full Pulumi program for deploying the tyk-operator Helm Chart.

    import * as k8s from "@pulumi/kubernetes"; // Create a new instance of the Helm chart for Tyk Operator. // Make sure to configure the settings according to the needs of your environment // and the Tyk Operator’s prerequisites. // You can customize the installation by adding your values in the `values` property. const tykOperatorChart = new k8s.helm.v3.Chart("tyk-operator", { chart: "tyk-operator", version: "0.9.0", // specify the desired chart version fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // specify the Helm repository }, namespace: "tyk-operator", // specify the namespace where you want to deploy the chart, it should be existing // For custom configurations, add values according to the chart's documentation. values: { // ... }, }); // Export the resources created by the Helm chart // This can be adjusted to export specific URLs, service names, or other metadata. export const operatorName = tykOperatorChart.getResourceProperty("v1/Service", "tyk-operator", "metadata").apply(m => m.name);

    This program does the following:

    • It imports the Pulumi Kubernetes package.
    • Uses the helm.v3.Chart class to declare a new Helm chart resource to deploy.
    • Specifies the chart name (tyk-operator) and version.
    • Points Pulumi to the Tyk Helm chart repository.
    • Sets the namespace where the chart will be installed. Ensure this namespace exists in your OpenShift cluster beforehand.
    • Optionally includes a values property where you can pass a custom configuration to the chart as needed.
    • Exports a resource property from the chart, in this case, the name of a service created by the chart, which could be useful for automatically retrieving the endpoint later on.

    Please ensure you have the following prerequisites:

    • Pulumi CLI: Install the Pulumi CLI on your local machine.
    • Node.js: You need Node.js installed to execute the Pulumi TypeScript program.
    • OpenShift CLI (oc): Ensure you have the OpenShift CLI tool to interact with your OpenShift cluster.
    • Kubernetes Configuration: The Pulumi program relies on the default kubeconfig to connect to the Kubernetes cluster. Make sure this is configured and pointing to your OpenShift cluster.

    After setting up the program, deploy it with the following Pulumi CLI commands:

    pulumi stack init tyk-operator-deployment pulumi up

    This will provision the Tyk Operator Helm chart in your OpenShift cluster in the specified namespace. You can see outputs defined in the program after the deployment, such as the name of the Tyk Operator service.
