1. Deploy the cluster-agent helm chart on Digital Ocean Kubernetes Service


    In order to deploy the cluster-agent Helm chart on a Digital Ocean Kubernetes service using Pulumi, you will follow several steps:

    1. Create a Digital Ocean Kubernetes Cluster: First, you set up the Kubernetes cluster on Digital Ocean using Pulumi's Digital Ocean provider.

    2. Deploy the Helm Chart: Once you have your Kubernetes cluster, you utilize Pulumi's Kubernetes provider to deploy the cluster-agent Helm chart to the cluster.

    Here's a simple TypeScript program in Pulumi that demonstrates how to accomplish these tasks:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1. Create a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC3, // Select the region for your cluster version: "latest", // Use the latest version of Kubernetes nodePool: { name: "default", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // You can select the size that fits your needs nodeCount: 2, // Specify the number of nodes in the node pool }, }); // Export the DigitalOcean Kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2. Deploy the cluster-agent Helm chart const clusterAgentChart = new kubernetes.helm.v3.Chart("cluster-agent", { chart: "cluster-agent", // The name of the chart version: "1.0.0", // Specify the version of the chart you wish to deploy fetchOpts: { repo: "https://your-helm-chart-repository.com/", // Replace with your Helm chart's repository URL }, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Deploying the Helm chart to your DigitalOcean Kubernetes cluster // Export the cluster name and endpoint export const clusterName = cluster.name; export const clusterEndpoint = cluster.endpoint;


    • We start by importing the necessary modules from Pulumi's Digital Ocean and Kubernetes libraries.

    • A Kubernetes cluster is provisioned on Digital Ocean with the name "do-cluster". We specify the region, Kubernetes version, size of the Droplet (VM in Digital Ocean terms), and the count of nodes in the node pool. It's crucial that you select values suitable for your requirements and budget.

    • Once the cluster is created, we obtain the raw Kubernetes configuration (kubeconfig), which is necessary for our Kubernetes provider to communicate with the Digital Ocean cluster.

    • In the second part, we instantiate a Helm chart resource, indicating the chart's name, version, and repository URL. Replace 'https://your-helm-chart-repository.com/' with the actual URL of the Helm chart repository containing cluster-agent.

    • We also create a Kubernetes provider instance configured with the kubeconfig obtained from our Kubernetes cluster. This provider is what allows Pulumi to deploy resources to that cluster.

    • Lastly, we export the cluster's name and endpoint for your reference. This information can be used to interact with your cluster using kubectl or any other Kubernetes tool.

    Please replace placeholders with actual values you intend to use, like the Helm chart version and repository URL. The region and Droplet size may also be adjusted based on your specific needs or availability.

    Remember to ensure your Pulumi and Digital Ocean credentials are configured properly in your environment before running this program. With this Pulumi program, you should be able to deploy the cluster-agent Helm chart to a Digital Ocean Kubernetes cluster successfully.
