1. Deploy the tyk-gateway helm chart on AWS EKS


    To deploy the tyk-gateway Helm chart on AWS EKS using Pulumi, you will follow these steps:

    1. Create an EKS cluster using the awsx package, which helps to abstract some of the complexity of setting up an EKS cluster.
    2. Once the cluster is created, you will utilize the kubernetes package to deploy the tyk-gateway Helm chart to the cluster.

    The program below is written in TypeScript and will guide you through these steps with detailed explanations. The awsx package offers high-level components that simplify the creation and configuration of AWS resources. The kubernetes package lets you interoperate with Kubernetes resources in a Pulumi program.

    Here's the Pulumi TypeScript program that carries out the deployment:

    import * as awsx from "@pulumi/awsx"; // AWS crosswalk package used for simplified resource creation import * as k8s from "@pulumi/kubernetes"; // Kubernetes package to deploy Kubernetes resources with Pulumi import * as pulumi from "@pulumi/pulumi"; // Create a new EKS cluster. const cluster = new awsx.eks.Cluster("my-cluster", { // Define the configuration for the EKS cluster here. You can specify the desired node count, // node type, and other Kubernetes and AWS settings. For a production-grade cluster, // you may want to use a dedicated VPC and configure security settings in depth. }); // Create a provider for the created cluster. This is used to configure the Kubernetes resources // to target the created EKS cluster. const clusterProvider = new k8s.Provider("my-cluster-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Define the Helm chart for Tyk Gateway from its repository. const tykGatewayChart = new k8s.helm.v3.Chart("tyk-gateway", { chart: "tyk-gateway", version: "<Chart Version>", // Specify the version of the Tyk Gateway chart you want to deploy. fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/" }, // The repository containing the Tyk Gateway chart. values: { // You can set custom values for your Tyk Gateway chart deployment, such as Tyk license key, configurations, and more. // refer to the chart's `values.yaml` or the official Tyk documentation for configurable values. }, }, { provider: clusterProvider }); // Ensure that this Helm chart is deployed using the EKS cluster provider. // Export the cluster name and kubeconfig, which can be used to interact with the cluster outside of Pulumi. export const clusterName = cluster.eksCluster.name; export const kubeconfig = pulumi.secret(cluster.kubeconfig);


    • We import necessary Pulumi packages for managing AWS resources and deploying Helm charts to Kubernetes.
    • We instantiate an EKS cluster named "my-cluster". This step will create an EKS cluster with default settings; however, you may customize it with more specific requirements according to your needs.
    • Once the cluster is created, we create a Provider which allows Pulumi to interact with the Kubernetes cluster by using the cluster's kubeconfig.
    • We deploy the tyk-gateway Helm chart using the information about its repository and the version. You would have to replace <Chart Version> with the specific version of the Tyk Gateway chart you want to deploy. You can also supply custom values to configure the Helm chart to suit your requirements.
    • Lastly, we export the clusterName and kubeconfig as stack outputs. The kubeconfig is marked as a secret because it contains sensitive information. These outputs can be used to interact with your Kubernetes cluster after the program has completed running.

    Please note that before running this program, make sure you have the AWS CLI configured with the necessary permissions to create EKS clusters, and you have the Pulumi CLI installed and set up. After setting up, you can run this program using the Pulumi CLI by executing pulumi up. The CLI will prompt you with a summary of the resources being created and ask for confirmation before proceeding with the deployment.
