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

    TypeScript

    To deploy a Helm chart on a DigitalOcean Kubernetes service, we will need to go through several steps using Pulumi. This process will involve creating a DigitalOcean Kubernetes cluster, then using the Helm chart to deploy the mTLS (Mutual Transport Layer Security) application onto the cluster. We will break down these steps as follows:

    1. Setting up a DigitalOcean Kubernetes Cluster: This is the underlying infrastructure where your mTLS application will run. The Kubernetes cluster provides the necessary features to manage and scale your application.

    2. Deploying the mTLS Helm Chart: Helm is a package manager for Kubernetes that allows you to define, install, and upgrade even the most complex Kubernetes applications. Helm charts help you define, install, and upgrade applications in Kubernetes.

    Let's walk through the Pulumi program in TypeScript that will perform these actions. Below is a detailed breakdown of the code:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", version: "1.21.5-do.0", nodePool: { name: "default", size: "s-2vcpu-2gb", nodeCount: 2, }, }); // Export the DigitalOcean Kubernetes cluster kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Set up a Kubernetes provider using the cluster's kubeconfig const k8sProvider = new k8s.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the mTLS Helm chart on the DigitalOcean Kubernetes cluster const mtlsChart = new k8s.helm.v3.Chart("mtls-chart", { chart: "mtls", // Replace with the actual chart name if different // Optionally specify the Helm repository using `repo: "https://example.com/helm-charts"` // If your chart requires custom values, specify them with `values: { /* ... */ }` }, { provider: k8sProvider }); // Export the Helm chart deployment name export const mtlsChartName = mtlsChart.name;

    Explanation

    • We start by importing the necessary Pulumi packages: @pulumi/pulumi for accessing the core Pulumi; @pulumi/digitalocean is the DigitalOcean provider package used to interact with DigitalOcean services, and @pulumi/kubernetes for the Kubernetes provider and resources.

    • Next, we define a DigitalOcean Kubernetes cluster with one node pool consisting of 2 nodes of the "s-2vcpu-2gb" size.

    • We export the kubeconfig which is necessary to interact with the Kubernetes cluster using tools like kubectl or any Kubernetes client library.

    • A Kubernetes provider is instantiated using the kubeconfig from the newly created DigitalOcean Kubernetes cluster. This tells Pulumi how to communicate with the Kubernetes API.

    • We then declare an instance of k8s.helm.v3.Chart to deploy our mTLS Helm chart. In this example, the chart is named mtls. You will need to replace it with the actual chart name and, if necessary, specify the Helm repository where Pulumi can find the chart.

    • Finally, we export the name of the Helm chart deployment so that it can be easily referenced or identified in the DigitalOcean dashboard, or through kubectl when managing resources.

    Next Steps

    To use this program:

    1. Save this code in a TypeScript file (e.g., index.ts).
    2. Run pulumi up to preview and deploy the changes. Pulumi CLI will interpret this code and provision the resources accordingly.
    3. Once applied, the kubeconfig output can be used to configure kubectl and interact with your cluster.

    Make sure that you have the Pulumi CLI installed and configured for use with DigitalOcean. You'll also need to have node and npm installed to work with the Pulumi TypeScript SDK.
