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


    To deploy the ocp-oauth-github Helm chart on Digital Ocean Kubernetes, we will first need to create a Kubernetes cluster on Digital Ocean. Once the cluster is up and running, we can install the Helm chart onto it. In Pulumi, this is achieved by defining resources in code, which describe the desired state of our infrastructure.

    Below you'll find a Pulumi program written in TypeScript to accomplish this. The program is divided into two parts:

    1. Provisioning the Digital Ocean Kubernetes Cluster: We'll define a digitalocean.KubernetesCluster resource to create the cluster.
    2. Deploying the Helm Chart: We'll define a kubernetes.helm.v3.Chart resource to deploy the ocp-oauth-github chart onto our newly created Kubernetes cluster.

    Here is the Pulumi TypeScript program that performs these steps:

    import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Provision a DigitalOcean Kubernetes Cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc1", // Select the region to deploy the cluster version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default-pool", size: "s-2vcpu-2gb", // Select the size for the nodes in the node pool nodeCount: 2, // Number of nodes to deploy }, }); // Once the cluster is provisioned, we get its kubeconfig for deploying Helm charts. const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Step 2: Deploy the ocp-oauth-github Helm chart on the cluster const helmChart = new k8s.helm.v3.Chart("ocp-oauth-github-chart", { // You should specify the correct chart version as per your requirements. chart: "ocp-oauth-github", version: "1.0.0", // Replace with the desired chart version fetchOpts: { // Replace with the correct repo URL where your Helm chart is hosted. repo: "https://charts.example.com/", }, // If your Helm chart requires custom values, specify them as an object. values: { // These are example values that might differ for your specific use case. replicaCount: 2, githubClientId: "your-github-client-id", githubClientSecret: "your-github-client-secret", }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig }) }); // Export the cluster's name and the Helm chart's status export const clusterName = cluster.name; export const chartStatus = helmChart.status;

    Let's go over the program:

    • Kubernetes Cluster Creation: We create a Kubernetes cluster using the digitalocean.KubernetesCluster resource. We specify the region (nyc1), the Kubernetes version (latest), the node pool configuration (2 nodes of s-2vcpu-2gb), and the node count (2).

    • Kubernetes Provider: Pulumi uses providers to interact with cloud services. Since we need to deploy resources into the Kubernetes cluster, we create a Kubernetes provider with the kubeconfig obtained from the Digital Ocean Kubernetes cluster.
