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


    To deploy the Tyk Operator on Google Kubernetes Engine (GKE) using Pulumi, you'll need to follow these steps:

    1. Set up a GKE cluster: This will be your Kubernetes environment where the Tyk Operator will run.
    2. Install the Helm chart: With Helm, you'll deploy the Tyk Operator Helm chart to the GKE cluster.

    Let's step through these tasks using Pulumi and TypeScript.

    Firstly, make sure you have Pulumi installed, and you are authenticated with Google Cloud. Additionally, you should have kubectl and helm CLI tools installed to interact with your Kubernetes cluster and manage Helm charts.

    1. Set Up GKE Cluster

    To create a GKE cluster, we'll use the @pulumi/gcp package. You'll need to define the GKE cluster resource within your Pulumi program. Here's how you could do it:

    import * as gcp from "@pulumi/gcp"; // Create a GKE cluster const cluster = new gcp.container.Cluster("tyk-operator-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "latest", nodeConfig: { preemptible: false, machineType: "n1-standard-1", oauthScopes: [ "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 Kubeconfig so that 'kubectl' can connect to the new Kubernetes cluster export const kubeconfig = cluster.masterAuth.apply(masterAuth => { const context = `${gcp.config.project}_${gcp.config.zone}_${cluster.name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${masterAuth.endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Use the new Kubernetes cluster as the provider for subsequent resources const k8sProvider = new kubernetes.Provider("k8sProvider", { kubeconfig: kubeconfig, });

    Here's what's happening in this code:

    • We're creating a basic GKE cluster named tyk-operator-cluster with two nodes.
    • The kubeconfig is being exported so that you can interact with the cluster using kubectl.
    • Finally, we are initializing a Pulumi Kubernetes provider which allows Pulumi to deploy Kubernetes resources to our newly created GKE cluster.

    2. Install the Helm Chart

    Next, we'll deploy the Tyk Operator Helm chart into the cluster we've just created. Pulumi has a Helm provider available in the @pulumi/kubernetes package that we can use. It simplifies Helm chart management on Kubernetes clusters managed by Pulumi.

    To deploy the Helm chart, you would add the following lines to your Pulumi program:

    import * as k8s from "@pulumi/kubernetes"; // Deploy the Tyk Operator Helm chart const tykOperatorChart = new k8s.helm.v3.Chart("tyk-operator", { chart: "tyk-operator", version: "0.9", // use the version that suits your requirements fetchOpts:{ repo: "https://helm.tyk.io/public/helm/charts/", }, }, { provider: k8sProvider }); // Export the Helm chart's status export const tykOperatorStatus = tykOperatorChart.status;

    This snippet deploys the tyk-operator Helm chart to the GKE cluster. We specify the chart name, version, and the repository URL. We tell Pulumi to use our GKE cluster for this deployment by passing the Kubernetes provider we initialized earlier.

    Once you have configured your index.ts with the code above, you can run the following commands to create the resources:

    pulumi up

    This will start the deployment process. Once completed, you should have a GKE cluster with the Tyk Operator running on it.

    To inspect the Helm release or interact with your GKE cluster, you can use kubectl with the kubeconfig outputted by Pulumi:

    pulumi stack output kubeconfig > kubeconfig.yaml export KUBECONFIG=./kubeconfig.yaml kubectl get all -n tyk-operator

    This sets the KUBECONFIG environment variable to the path of the kubeconfig file that Pulumi outputs and then uses kubectl to get all resources in the tyk-operator namespace.

    Remember, this program creates real resources in your GCP account and may incur costs.

    This is a high-level overview and should be adjusted based on the specific requirements, the size and configuration details of your GKE cluster, and any specific configurations you want for the Tyk Operator deployment.
