1. Deploy the tyk-stack helm chart on Kubernetes


    To deploy the tyk-stack Helm chart on Kubernetes using Pulumi, you will need to use the Chart resource from the Pulumi Kubernetes provider. The Chart resource allows you to deploy a Helm chart from a repository or a local path.

    Here are the steps you will follow in the program:

    1. Import Pulumi Packages: Use the necessary Pulumi Kubernetes package to interact with Kubernetes.
    2. Create a Kubernetes Provider: If necessary, create an instance of a Kubernetes provider to communicate with a specific Kubernetes cluster.
    3. Deploy the Helm Chart: Use the Chart resource to deploy the tyk-stack Helm chart with the required configurations.

    Below is a Pulumi program written in TypeScript, which deploys the tyk-stack Helm chart on a Kubernetes cluster. This assumes you have already configured Pulumi with access to a Kubernetes cluster (e.g., via kubeconfig).

    import * as k8s from "@pulumi/kubernetes"; // The version of the Helm chart you want to deploy. You may want to update it to the desired version. const chartVersion = "x.y.z"; // Replace 'x.y.z' with the actual chart version. // Deploying the tyk-stack Helm chart const tykStackChart = new k8s.helm.v3.Chart("tyk-stack", { chart: "tyk-headless", // This is the name of the chart in the Helm repository. version: chartVersion, // Depending on the Helm repository, you may need to specify the repository URL. // For example, if the chart is in the official Tyk Helm repository: // repositoryOpts: { // repo: "https://helm.tyk.io/public/helm/charts/", // }, // Specify the values for the Helm chart as needed. This is an example set of values: values: { gateway: { replicaCount: 1, }, dashboard: { replicaCount: 1, // You may need to set license and other settings here }, // Add other configurations for the Tyk stack components as necessary }, // Namespace where you want to install the chart. If not specified, it will be installed in the default namespace. // namespace: "tyk", }); // Export the Gateway URL export const gatewayUrl = tykStackChart.getResourceProperty("v1/Service", "tyk-gateway", "status").apply(status => { // Construct the URL from the service status, which might vary based on your environment. // This is an example assuming a LoadBalancer service on a cloud provider. const ingress = status.loadBalancer.ingress[0]; return ingress.ip ? `http://${ingress.ip}` : `http://${ingress.hostname}`; });

    This program does the following:

    • It imports the Kubernetes package from Pulumi to interact with the Kubernetes API.
    • It creates a new Chart resource, which represents the Helm chart you want to deploy.
    • The repositoryOpts can be specified if the Helm chart is in a Helm repository. In this case, we have commented it out since you'll either specify the repo for where the tyk-stack is stored, or you might have it locally. If you're using a local chart, the path property would be used instead.
    • The values object allows you to configure the Helm chart with the desired values. This is where you'd customize the deployment to meet your requirements.
    • Lastly, it exports the gateway URL, making the assumption that tyk-gateway service is of LoadBalancer type which may provide an external IP or hostname.

    Please adjust the chart, version, repositoryOpts, namespace, and values fields as per your requirements and the specifics of the tyk-stack Helm chart you wish to deploy. If you have a specific configuration you'd like to use or other advanced settings, you'll need to modify the values or add additional options to the Chart resource.
