1. Deploy the ethereum helm chart on Google Kubernetes Engine (GKE)


    Deploying an Ethereum Helm chart on Google Kubernetes Engine (GKE) involves several steps: setting up a GKE cluster, installing Helm in your local development environment, and then using Helm to deploy the Ethereum chart onto the GKE cluster.

    First, let's set up a GKE cluster. We'll use the google-native.container/v1.Cluster resource to create a new Kubernetes cluster in GKE. This resource allows you to provision and manage GKE clusters using native GCP fields and properties directly within Pulumi.

    Here is how you would set up the GKE cluster using Pulumi:

    import * as gcp from "@pulumi/gcp"; // Create a GKE cluster. const cluster = new gcp.container.Cluster("ethereum-cluster", { initialNodeCount: 2, nodeVersion: "latest", minMasterVersion: "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 and Kubeconfig export const clusterName = cluster.name; export const kubeconfig = cluster.endpoint.apply(endpoint => { return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${cluster.masterAuth[0].clusterCaCertificate} server: https://${endpoint} name: ${cluster.name}`; });

    This code does the following:

    1. Imports the necessary GCP module from Pulumi's Google Cloud provider.
    2. Creates a GKE cluster with a specified number of nodes and machine type.
    3. Exports the cluster name and endpoint information.

    Next, you need to set up Helm in your local development environment. After installing Helm, you would typically add the appropriate chart repository and then use Helm commands to deploy your chart. Unfortunately, Pulumi does not directly manage Helm chart installations.

    However, it is possible to use Pulumi's exec function to run arbitrary commands, including Helm commands. This feature can be used to script the Helm deployment within Pulumi's TypeScript program, although it is a bit more advanced and not an officially recommended pattern due to its imperative nature.

    For the sake of simplicity, I will assume that you will run the Helm commands separately from the Pulumi program. Once your cluster is provisioned by Pulumi, you would execute the following commands in your shell to deploy the Ethereum chart:

    helm repo add ethereum https://helm.ethereum.org helm repo update helm install my-ethereum ethereum/ethereum

    Please remember to configure kubectl using the kubeconfig exported from the Pulumi program before running these Helm commands.

    After running these commands, Helm will deploy the Ethereum chart to your GKE cluster, and you can then interact with your Ethereum nodes using kubectl.
