1. Deploy the oauth-server helm chart on Digital Ocean Kubernetes Service


    Deploying an oauth-server helm chart on Digital Ocean's Kubernetes service using Pulumi requires a few steps:

    1. Set up a Digital Ocean Kubernetes cluster resource.
    2. Install the helm chart onto the Kubernetes cluster.

    To begin, you'll need to have Pulumi installed along with the necessary Pulumi provider for Digital Ocean. Next, the code below illustrates the TypeScript program that achieves the deployment of the oauth-server helm chart on a Digital Ocean Kubernetes cluster.

    Here's a step-by-step guide to the code:

    Step 1: Create a Digital Ocean Kubernetes Cluster

    First, we define a KubernetesCluster resource using Digital Ocean's Pulumi provider. This represents the Kubernetes cluster where your helm chart will be deployed.

    Step 2: Deploy the Helm Chart

    Once the cluster is available, we then use the Chart resource from @pulumi/kubernetes to deploy the oauth-server helm chart. This resource does not require pre-configuration of the helm repository because you will specify the repo property where your chart is hosted.

    Now let's look at the program:

    import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Provision the DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: digitalocean.Regions.NYC1, // Choose the region closest to your app's users version: "latest", nodePool: { name: "default-pool", size: digitalocean.DropletSlugs.DropletS2VCPU2GB, // Choose according to your needs nodeCount: 2, // Number of nodes (VMs) in the node pool }, }); // Export the Kubeconfig and Cluster name export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const clusterName = cluster.name; // Step 2: Deploy the oauth-server helm chart // The Kubernetes provider uses the generated kubeconfig from the cluster. const k8sProvider = new kubernetes.Provider("do-k8s", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // The Helm Chart deployment of oauth-server. Replace `repo` and `chart` with actual values. const oauthServerChart = new kubernetes.helm.v3.Chart("oauth-server", { chart: "oauth-server", // The name of the chart version: "1.0.0", // Specify the chart version you want to deploy namespace: "default", // The Kubernetes namespace to deploy into (create this if it doesn't exist) fetchOpts: { repo: "https://charts.example.com/", // Replace with your helm chart's repository URL }, }, { provider: k8sProvider }); // Optional: Export URLs or other information like the chart status export const oauthServerChartStatus = oauthServerChart.status;

    Understanding the Code:

    • We start by importing the necessary Pulumi packages for Digital Ocean and Kubernetes.
    • Next, we create a new Kubernetes cluster in Digital Ocean with the specified region, version, and node pool configuration.
    • We then create a Kubernetes provider configured with the cluster's kubeconfig.
    • Using the Kubernetes provider, we deploy the oauth-server Helm chart with a specified version and repository URL.
    • Optionally, you could export additional outputs such as the Helm chart status or other resources created as part of the chart deployment.

    Please replace "https://charts.example.com/" with the actual repository URL where your oauth-server Helm chart is hosted.

    Once you have this program, you would run it using the usual Pulumi workflow:

    1. Run pulumi up to execute the code and create the resources.
    2. Pulumi will show you a preview of what will be created.
    3. If the preview looks good, you can confirm and proceed with the deployment.

    Ensure that you have installed Pulumi CLI and configured your Digital Ocean access token. Once the resources are created, you can manage and update them through the Pulumi CLI or the Pulumi Console web interface.
