1. Deploy the kyuubi helm chart on Digital Ocean Kubernetes Service


    To deploy the Kyuubi Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you would need to follow these steps:

    1. Create a Kubernetes Cluster: You'll need a Kubernetes cluster on Digital Ocean. Pulumi's digitalocean package provides a KubernetesCluster resource for this purpose. You will need to specify details like the region, version, and node pool configuration for your cluster.

    2. Install Helm and Add the Kyuubi Helm Repository: Before you can install a Helm chart, you need to have Helm installed on your local machine where you're running Pulumi. Then, you would add the repository that contains the Kyuubi chart.

    3. Deploy Kyuubi using the Helm Chart: Once Helm is set up and the repository is added, you can use Pulumi's kubernetes package, specifically the helm.sh/v3.Chart resource, to deploy Kyuubi onto your Digital Ocean Kubernetes cluster.

    Here is the Pulumi program written in TypeScript that accomplishes these steps:

    import * as digitalocean from '@pulumi/digitalocean'; import * as kubernetes from '@pulumi/kubernetes'; import * as pulumi from '@pulumi/pulumi'; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster('do-cluster', { region: 'nyc1', // Replace with the desired region version: 'latest', // Use a specific version or 'latest' for the latest stable version nodePool: { name: 'default-pool', size: 's-2vcpu-2gb', // The size of Droplets to use (e.g., s-1vcpu-2gb) nodeCount: 3, // The number of Droplet instances in the node pool }, }); // Export the cluster details export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Set up Kubernetes provider to use the generated kubeconfig const k8sProvider = new kubernetes.Provider('k8s-provider', { kubeconfig: kubeconfig, }); // Deploy Kyuubi using a Helm Chart const kyuubiChart = new kubernetes.helm.v3.Chart('kyuubi', { chart: 'kyuubi', // Chart name here should be the same as used in 'helm repo add' fetchOpts: { // Replace with the actual repository details where the Kyuubi chart is available repo: 'https://kyuubi.apache.org/kyuubi-helm/', }, // Add any custom values you want to pass to the Helm chart values: { // for example // service: { // type: "LoadBalancer", // }, }, }, { provider: k8sProvider });

    What the above code does:

    • DigitalOcean Kubernetes Cluster: This code defines a DigitalOcean Kubernetes Cluster (digitalocean.KubernetesCluster) in the nyc1 region with three nodes of size s-2vcpu-2gb (2 CPUs, 2GB of RAM). This configuration might be more than you need for a small project or insufficient for a large one; adjust accordingly.

    • Exporting the kubeconfig: After creating the cluster, the kubeconfig needed to connect and manage the cluster is exported. This would typically be used on your local system to access the cluster with kubectl.

    • Kubernetes Provider: Before using Helm to deploy a chart, we need to configure the Kubernetes provider (kubernetes.Provider) with the kubeconfig from our newly created cluster to ensure that all subsequent resources are deployed to that cluster.

    • Helm Chart: The kubernetes.helm.v3.Chart class is used to deploy a Helm chart in the cluster. You specify the chart name and optional values that are specific to the Helm chart you want to install. In this case, 'kyuubi' is specified as the chart name, and a placeholder for further values has been commented out. You will need to provide the appropriate Helm repository where the Kyuubi chart is hosted. The code assumes it is available at 'https://kyuubi.apache.org/kyuubi-helm/' but please verify this as you might need to change it. You can customize the chart values in the values object to suit your configuration.

    The above program can be modified to accommodate any custom configurations or requirements specified for the Kyuubi chart.

    To deploy this Pulumi program:

    • Install Pulumi and configure it to use DigitalOcean by following the instructions here.
    • Make sure you have Helm installed locally and that you're authenticated with the DigitalOcean Kubernetes cluster.
    • Create a new directory, run pulumi new typescript to create a new Pulumi project, replace the content of index.ts with the above code, and run pulumi up to preview and deploy the changes.
