1. Deploy the web3-indexer helm chart on Digital Ocean Kubernetes Service


    To deploy the web3-indexer helm chart on the Digital Ocean Kubernetes Service using Pulumi, we'll follow these steps:

    1. Create a Kubernetes Cluster on Digital Ocean: We'll start by declaring a digitalocean.KubernetesCluster resource to provision a Kubernetes cluster on Digital Ocean.

    2. Install the Helm Chart: Once we have a Kubernetes cluster, we'll install the web3-indexer Helm chart using the kubernetes.helm.v3.Chart resource, which is a Pulumi resource that allows you to manage Helm charts in a Kubernetes cluster.

    Here's a detailed program that includes these steps:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Provision a Digital Ocean Kubernetes cluster // Documentation: https://www.pulumi.com/registry/packages/digitalocean/api-docs/kubernetescluster/ const cluster = new digitalocean.KubernetesCluster("web3-indexer-cluster", { // Example configuration values; you should adjust these based on your needs region: "nyc1", version: "latest", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 3, // Number of nodes to provision }, }); // Step 2: Deploy the web3-indexer Helm chart to the cluster // Documentation for Helm chart resource: https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/ const helmChart = new k8s.helm.v3.Chart("web3-indexer", { // Assuming Helm chart for web3-indexer is located in the official repo // You need to replace with the correct repository and chart name if it's different chart: "web3-indexer", version: "1.0.0", // Specify the version of the Helm chart you wish to deploy fetchOpts: { repo: "https://charts.example.com/", // Replace with the correct Helm repo URL }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Stack exports to retrieve important information about the created resources export const clusterName = cluster.name; export const clusterKubeconfig = cluster.kubeConfigs[0].rawConfig;

    In this TypeScript program, we import the required Pulumi packages to work with Digital Ocean and Kubernetes. Replace https://charts.example.com/ with the repository that contains the web3-indexer Helm chart.

    The digitalocean.KubernetesCluster declaration creates a Kubernetes cluster with a default node pool. You can customize the region, version, and nodePool configurations to suit your requirements.

    The k8s.helm.v3.Chart declaration stands for the web3-indexer helm chart deployment. You have to make sure that chart, version, and repo values match the actual Helm chart you wish to install.

    The { provider: new k8s.Provider(...) } ensures that the Helm chart is deployed to the newly created Digital Ocean Kubernetes cluster.

    Lastly, we export some stack outputs like the clusterName and clusterKubeconfig. These outputs are useful if you want to interact with your Kubernetes cluster using kubectl or other Kubernetes tools outside of Pulumi.
