1. Deploy the mongo-sed helm chart on Digital Ocean Kubernetes Service


    To deploy the mongo-sed Helm chart on the Digital Ocean Kubernetes Service using Pulumi, you'll need to follow these steps:

    1. Create or configure a Digital Ocean Kubernetes cluster.
    2. Install the Helm chart on the Kubernetes cluster.

    For the Kubernetes cluster, we'll use the digitalocean.KubernetesCluster resource, which allows you to create and manage a Kubernetes cluster on Digital Ocean. Once the cluster is up, we'll use the kubernetes.helm.sh/v3.Chart resource to deploy the mongo-sed Helm chart to the cluster.

    Below is the TypeScript program that performs these tasks. Note that I'm assuming mongo-sed is the name of the Helm chart that you wish to deploy, but this may need adjustment if the actual chart name differs or if it requires a specific repository. Helm charts can also require additional configuration values, which you'll pass as an object to the values property in the Helm chart resource.

    Please replace the <YOUR_CLUSTER_NAME> and <REGION> placeholders with your desired cluster name and region respectively. Additionally, if the Helm chart mongo-sed is in a Helm repository, you'll have to provide the repository URL and the chart's version.

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a Digital Ocean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("<YOUR_CLUSTER_NAME>", { region: "<REGION>", // Specify the region for your cluster, for example "nyc3" version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // This is the size of each node in the node pool nodeCount: 2, // This will create 2 nodes in the default node pool }, }); // Once the cluster is provisioned, we can configure a Kubernetes provider that uses the kubeconfig from the cluster const k8sProvider = new k8s.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the mongo-sed Helm chart on the cluster using the k8sProvider const mongoChart = new k8s.helm.v3.Chart("mongo-sed", { chart: "mongo-sed", // Uncomment below if the Helm chart is hosted in a Helm repository // repo: "https://charts.example.com/", // version: "1.0.0", // Specify the chart version values: { // Specify any custom values for your Helm chart }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    Explanation of Resources:

    • digitalocean.KubernetesCluster: This resource is used to provision a Kubernetes cluster on Digital Ocean. You need to specify the region, version, and details about the node pool.
    • k8s.Provider: The Kubernetes provider resource is how Pulumi communicates with a Kubernetes cluster. In this case, it's configured with the kubeconfig that is output by the Digital Ocean Kubernetes cluster, which allows Pulumi to deploy resources onto that cluster.
    • k8s.helm.v3.Chart: This is the resource used to deploy Helm charts to a Kubernetes cluster. It takes parameters such as chart, repo, version, and values that allow you to specify the Helm chart you want to deploy and configure it according to your needs.

    The kubeconfig output at the end provides you with the kubeconfig of your cluster, which you can use with kubectl to interact with your cluster from your local machine.

    Note: Before running this Pulumi program, make sure you have authenticated to Digital Ocean and have the necessary access rights to create and manage resources. Also, you'll need to have Pulumi CLI installed and configured on your local machine.

    When ready, navigate to the directory containing this Pulumi program and run pulumi up to preview and deploy the resources. After deployment, you should have a running Digital Ocean Kubernetes cluster with the mongo-sed Helm chart installed.
