1. Deploy the duoauthproxy-radius-simple helm chart on Digital Ocean Kubernetes Service


    To deploy the duoauthproxy-radius-simple Helm chart on Digital Ocean Kubernetes Service using Pulumi, we shall take the following steps:

    1. Create a Digital Ocean Kubernetes Cluster.
    2. Deploy the Helm chart on the cluster.

    Here is a detailed breakdown of how the Pulumi program accomplishes this:

    • Digital Ocean Kubernetes Cluster: We create a Kubernetes cluster on Digital Ocean using the digitalocean.KubernetesCluster resource. We specify necessary configuration details such as the region, version, and node pool details.

    • Helm Chart Deployment: Once the cluster is available, we install the Helm chart using the kubernetes.helm.v3.Chart resource. We'll assume that the duoauthproxy-radius-simple chart is available in a known Helm chart repository. In this deployment, we provide the necessary chart details, such as the name and version, or repository URL if it is not a stable chart you may get from the Helm stable repository.

    Let's look at the Pulumi TypeScript code for deploying the Helm chart on Digital Ocean Kubernetes Service.

    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("do-cluster", { region: "nyc3", // For example, New York 3 region. version: "1.21.5-do.0", // Specify the version of Kubernetes. nodePool: { name: "default", size: "s-2vcpu-2gb", // Specify the size of the nodes. nodeCount: 2, // Number of nodes in the node pool. }, }); // Create a provider for the Digital Ocean Kubernetes cluster. const k8sProvider = new k8s.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Deploy the duoauthproxy-radius-simple Helm chart. const duoAuthProxyChart = new k8s.helm.v3.Chart("duoauthproxy-radius-simple", { chart: "duoauthproxy-radius-simple", // Assuming the chart is in a Helm repository, specify the repo details. // If it's a local chart, provide the path using `path: "./path/to/chart"`. fetchOpts: { repo: "https://helm-repo.example.com/", // Replace with your Helm repository URL. }, // Define any custom values you want to provide to the Helm chart. values: { // e.g., to set a custom admin password // adminPassword: "verysecurepassword", }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    In this program:

    • We initialized a new Digital Ocean Kubernetes Cluster configured in the New York 3 region. We've created a small node pool with two nodes of a moderate size suitable for small workloads.

    • We defined a Kubernetes provider which allows Pulumi to interact with the newly created Digital Ocean Kubernetes cluster using the generated kubeconfig.

    • We deployed the duoauthproxy-radius-simple Helm chart using the k8s.helm.v3.Chart resource, pointing to the chart in a hypothetical Helm repository.

    Don't forget to replace "https://helm-repo.example.com/" with the actual repository URL where the duoauthproxy-radius-simple Helm chart is hosted, and adjust the other placeholders to match your actual configuration needs.

    You can run this Pulumi program using the usual Pulumi CLI commands:

    pulumi up

    This command will provision the resources as per the defined program. Please ensure you have Pulumi installed and set up with the necessary cloud provider credentials configured for Digital Ocean.
