Deploy the zookeeper-helm-chart helm chart on Google Kubernetes Engine (GKE)

To deploy the zookeeper-helm-chart Helm chart on Google Kubernetes Engine (GKE), we'll first ensure that a GKE cluster is up and running. Then we will install the Helm chart onto that cluster. We'll proceed with the following steps using Pulumi with TypeScript:

1. Provision a GKE Cluster: We need a Kubernetes cluster where our Helm chart will be deployed. We'll use the google-native.container.v1.Cluster resource to create a new GKE cluster.

2. Setup K8s Provider: Once our cluster is up, we'll configure the Kubernetes provider to connect to the GKE cluster. This provider facilitates the deployment of Kubernetes resources.

3. Deploy Helm Chart: We will use the kubernetes.helm.v3.Chart resource to deploy the zookeeper-helm-chart onto our GKE cluster.

Here's a complete Pulumi program that accomplishes the deployment:

import * as gcp from "@pulumi/gcp";
import * as k8s from "@pulumi/kubernetes";
import * as pulumi from "@pulumi/pulumi";

// Create a GKE cluster
const cluster = new gcp.container.Cluster("zookeeper-cluster", {
    initialNodeCount: 2,
    minMasterVersion: "latest",
    nodeVersion: "latest",
    nodeConfig: {
        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 Cluster name
export const clusterName = cluster.name;

// Export the Kubeconfig to access the Cluster
export const kubeconfig = pulumi.
    all([cluster.name, cluster.endpoint, cluster.masterAuth]).
    apply(([name, endpoint, masterAuth]) => {
        const context = `${gcp.config.project}_${gcp.config.zone}_${name}`;
        return `apiVersion: v1
clusters:
- cluster:
    certificate-authority-data: ${masterAuth.clusterCaCertificate}
    server: https://${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
`;
    });

// Create a Kubernetes provider instance that uses our cluster from above.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: kubeconfig,
});

// Create a Helm Release for the zookeeper chart
const zookeeperHelmChart = new k8s.helm.v3.Chart("zookeeper-helm-chart", {
    chart: "zookeeper",
    fetchOpts:{
        repo: "https://charts.bitnami.com/bitnami",
    },
    version: "5.14.3", // specify the version of the chart to deploy
}, { provider: k8sProvider });

// Export the Helm Chart status
export const zookeeperHelmChartStatus = zookeeperHelmChart.status;

This program does the following:

• Defines a GKE cluster with the necessary OAuth scopes and node specifications. It sets the master and node versions to the latest available GKE versions.
• Exports the clusterName and kubeconfig necessary to interact with the cluster using kubectl or other Kubernetes tooling.
• Creates a k8s.Provider resource that knows how to communicate with our GKE cluster using the exported kubeconfig.
• Deploys the ZooKeeper Helm chart by specifying it with k8s.helm.v3.Chart. This command fetches the specified version of the Helm chart from the Bitnami repository and installs it on the cluster associated with our Kubernetes provider.
• Exports the status of the ZooKeeper Helm chart release so we can confirm if it was deployed successfully.

To run this Pulumi program:

1. Install Pulumi CLI and set up Google Cloud SDK (gcloud).
2. Authenticate with GCP and set the default project and zone.
3. Install Node.js and npm to run the Pulumi program.
4. Place the above code in a file named index.ts.
5. Run npm install to install the necessary Pulumi and GCP packages.
6. Run pulumi up to execute the program.

Please replace the placeholders like chart version with the actual version you wish to deploy or omit to use the latest. Also, ensure that your GCP project and zone are configured before running this program.

Also, note that provisioning GKE clusters and deploying Helm charts may incur costs in your GCP account, and appropriate billing setup should be ensured.
