1. Deploy the tyk-gateway helm chart on Google Kubernetes Engine (GKE)


    To deploy the Tyk Gateway helm chart on Google Kubernetes Engine (GKE) using Pulumi, you would first need to create a GKE cluster and then deploy the helm chart onto this cluster.

    We will be using the following Pulumi resources:

    • google-native.container/v1.Cluster: This will create a GKE cluster in the specified location with the desired settings. This resource allows us to configure all the necessary settings for our Kubernetes cluster, including node pools, networking, and access controls. For the full list of configurable options and their descriptions, you can refer to the official Pulumi documentation for GKE Cluster.
    • kubernetes.helm.v3.Chart: This Pulumi resource is used to deploy a helm chart to a Kubernetes cluster. Helm charts help to simplify the deployment and management of applications on Kubernetes.

    Below is a detailed TypeScript program that demonstrates how to create a GKE cluster and deploy the Tyk Gateway helm chart on it:

    import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Configurable variables for the GKE cluster const clusterName = "tyk-gateway-cluster"; const clusterLocation = "us-west1"; // You can select an appropriate location const nodeCount = 2; // Number of nodes in the GKE cluster // Create a GKE cluster. const cluster = new gcp.container.Cluster(clusterName, { name: clusterName, location: clusterLocation, initialNodeCount: nodeCount, nodeConfig: { machineType: "n1-standard-1", // Assumed machine type, can be adjusted as per requirements oauthScopes: [ // Set of minimum scopes needed for the GKE nodes "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); // Export the Cluster name export const gkeClusterName = cluster.name; // Create a Kubernetes provider instance that uses our GKE cluster from above. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigRaw, }); // Deploy the Tyk Gateway helm chart. const tykGatewayChart = new k8s.helm.v3.Chart("tyk-gateway", { chart: "tyk-gateway", version: "1.0.0", // Replace with an actual chart version fetchOpts: { repo: "https://helm.tyk.io/public/helm/charts/", // Replace with the Tyk Gateway helm chart repository URL }, }, { provider: k8sProvider }); // Export the Helm chart's status export const helmChartStatus = tykGatewayChart.status;

    This Pulumi program performs the following actions:

    • Imports the necessary Pulumi packages for working with GCP and Kubernetes.
    • Defines configurable variables for the GKE cluster such as clusterName, clusterLocation, and nodeCount.
    • Creates a new GKE cluster using the gcp.container.Cluster class with the specified machine type and OAuth scopes for the nodes.
    • Exports the cluster name as a stack output.
    • Sets up a Kubernetes provider using the newly created GKE cluster's kubeConfigRaw data.
    • Deploys the Tyk Gateway helm chart to the GKE cluster using the k8s.helm.v3.Chart class.
    • Exports the status of the helm chart deployment as a stack output.

    To apply this program:

    1. Save the above TypeScript code into a file named index.ts.
    2. Run pulumi up within the same directory as your index.ts file and Pulumi will begin to create the GKE cluster and deploy the Tyk Gateway helm chart.
    3. After completion, Pulumi CLI will output the exported variables, including the gkeClusterName and helmChartStatus.

    You can further customize this program by editing the configuration variables or by adding additional options to the GKE cluster and Helm chart deployments.
