1. Deploy the ibm-minio-objectstore helm chart on Digital Ocean Kubernetes Service


    To deploy the IBM MinIO Object Store Helm chart on Digital Ocean's Kubernetes Service using Pulumi, you'll follow these general steps:

    1. Create a DigitalOcean Kubernetes cluster if you don't already have one.
    2. Install the Helm chart for MinIO into your Kubernetes cluster.

    For this task, we'll leverage Pulumi's TypeScript SDK and the following packages:

    • @pulumi/digitalocean to provision the DigitalOcean Kubernetes cluster.
    • @pulumi/kubernetes to work with Kubernetes resources, including deploying the Helm chart.

    Below you'll find a Pulumi program written in TypeScript that provisions a new DigitalOcean Kubernetes cluster and deploys the IBM MinIO Object Store Helm chart. I'll go step by step explaining each part, with the detailed code comments provided within the code itself.

    First, let's provide the code that sets up the Kubernetes cluster on DigitalOcean. We'll instantiate a digitalocean.KubernetesCluster resource that represents the cluster configuration.

    Then, after the cluster is set up, we'll use a kubernetes.helm.v3.Chart resource to deploy the MinIO Object Store Helm chart onto the cluster. Note that Helm charts are a convenient way to deploy and manage applications on Kubernetes clusters, and MinIO has an official Helm chart that can be used for this purpose.

    Here's the Pulumi TypeScript program:

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // DigitalOcean Kubernetes cluster configuration const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", version: "1.21.5-do.0", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2, }, }); // Kubernetes provider to connect to the newly created DigitalOcean Kubernetes cluster const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy IBM MinIO Object Store Helm chart const minioChart = new k8s.helm.v3.Chart("minio", { chart: "ibm-minio-objectstore", version: "2.5.30", // Use the desired version of the Helm chart fetchOpts: { repo: "https://charts.min.io/", }, // Define any custom MinIO configurations here values: { accessKey: "YOUR-ACCESS-KEY", secretKey: "YOUR-SECRET-KEY", // You can include additional custom values as needed for your MinIO deployment }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Export the IP address assigned to the MinIO service export const minioServiceIP = minioChart.getResourceProperty("v1/Service", "minio", "status").apply(status => status.loadBalancer.ingress[0].ip);

    The sequence of the code is as follows:

    1. Import the necessary DigitalOcean and Kubernetes modules from Pulumi's package.
    2. Create a DigitalOcean Kubernetes cluster with a specified region, version, and node pool configuration.
    3. Instantiate a Kubernetes provider using the kubeconfig of the new cluster that allows Pulumi to interact with the cluster.
    4. Deploy the MinIO Object Store Helm chart using k8s.helm.v3.Chart, specifying the chart's name, a specific chart version, and the chart's repository. You can pass custom values for various MinIO configurations, like the accessKey and secretKey.
    5. Export the kubeconfig so it can be used outside of Pulumi to interact with the Kubernetes cluster.
    6. Also, export the IP address of the MinIO service assuming it's exposed via a LoadBalancer.

    Make sure to replace YOUR-ACCESS-KEY and YOUR-SECRET-KEY with your actual MinIO credentials. These will be used to access the MinIO dashboard and S3 API.

    After running this Pulumi program, the DigitalOcean Kubernetes cluster will be provisioned, and the IBM MinIO Object Store will be deployed and accessible at the exported service IP address.
