1. Deploy the rook-operator helm chart on Digital Ocean Kubernetes Service


    Deploying a Helm chart on a Kubernetes cluster managed by Digital Ocean involves a few steps. First, you need to provision a Kubernetes cluster on Digital Ocean. Next, you would deploy the Helm chart to the cluster.

    Here's how you can achieve this with Pulumi in TypeScript:

    1. Provision a Digital Ocean Kubernetes cluster:

      • Use the digitalocean.KubernetesCluster resource to create a managed Kubernetes service on Digital Ocean.
    2. Deploy the Helm chart:

      • Use the kubernetes.helm.v3.Chart resource to deploy the rook-operator chart from the Helm repository.

    Below is the TypeScript program demonstrating these steps:

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "1.21.5-do.0", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2, }, }); // Create a provider for the Digital Ocean Kubernetes cluster const provider = new k8s.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the rook-operator Helm chart const rookOperator = new k8s.helm.v3.Chart("rook-operator", { chart: "rook-ceph", version: "1.7.6", // specify the version of the rook-operator or omit to use the latest fetchOpts: { repo: "https://charts.rook.io/release", // Helm repository for rook-operator }, }, { provider }); // Ensure the Helm chart is installed using the provider from our DO cluster // Export the Digital Ocean Kubernetes cluster endpoint and name export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint;

    This is a brief explanation of the components:

    • We call new digitalocean.KubernetesCluster to create the Kubernetes cluster. We provide it a name, the region where the cluster will be hosted, the version of Kubernetes, and the configuration of the node pool that the cluster will use.

    • For deploying Helm charts to the new cluster, we instantiate a k8s.Provider and pass in the kubeconfig obtained from the newly created Digital Ocean Kubernetes cluster. This provider is then used to interact with the Kubernetes cluster API.

    • With new k8s.helm.v3.Chart, we deploy the rook-operator Helm chart to the Kubernetes cluster. The chart argument specifies which chart to deploy (in this case, rook-ceph), and the fetchOpts provide details about where to fetch the chart from.

    • We have also configured some exports, like kubeconfig, clusterName, and clusterEndpoint, to allow interaction with the cluster outside of Pulumi.

    Please make sure to replace parameters like the cluster region, name, and node count with values that match your requirements. Also, version numbers for Kubernetes and the Helm chart may vary, so you should specify the versions that are compatible with your setup.

    To apply this Pulumi program, you would run pulumi up in the terminal after saving the above program to a file (e.g., index.ts). Make sure you have the Pulumi CLI installed and have authenticated with your Digital Ocean account, so Pulumi can manage resources on your behalf.

    Remember to review the Pulumi documentation for the Digital Ocean provider and the Helm provider for more information and to ensure you set up your Pulumi and cloud environment correctly:
