1. Deploy the keycloak-operator-legacy helm chart on Digital Ocean Kubernetes Service


    To deploy the keycloak-operator-legacy Helm chart on DigitalOcean's Kubernetes Service (DOKS), we'll first create a Kubernetes cluster using digitalocean.KubernetesCluster. After that, we'll use Pulumi's kubernetes.helm.v3.Chart to deploy the Helm chart to the cluster we've created.

    Here's the program that does that, and I'll break it down step by step:

    Step 1: Create a Kubernetes Cluster

    We define a KubernetesCluster which is a managed Kubernetes service provided by DigitalOcean. We specify the region, node size, and node count here.

    Step 2: Deploy the Keycloak Operator Helm Chart

    Once the cluster is provisioned, we deploy the Keycloak operator Helm chart using the Chart resource from the @pulumi/kubernetes package. This resource represents a Helm chart within your Kubernetes cluster which is a collection of pre-configured Kubernetes resources.

    Let's get to the code:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("do-cluster", { region: "nyc3", // Specify the region for your DOKS cluster version: "latest", // Use the latest available version of Kubernetes nodePool: { name: "default", size: "s-2vcpu-2gb", // Specify the size for your nodes within the node pool nodeCount: 2, // Specify the initial number of nodes in the node pool }, }); // Step 2: Deploy the "keycloak-operator-legacy" Helm chart on the DOKS cluster const keycloakOperatorChart = new kubernetes.helm.v3.Chart("keycloak-operator", { chart: "keycloak-operator-legacy", version: "1.0.0", // Replace with the correct version of the chart namespace: "keycloak", // Specify the namespace where you want to install the chart fetchOpts: { repo: "https://your-helm-chart-repository.com", // Replace with the actual repository }, }, { provider: new kubernetes.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Export the cluster's kubeconfig export const kubeconfig = cluster.kubeConfigs[0].rawConfig;

    In this program:

    • We use the digitalocean provider to provision a new Kubernetes cluster.
    • The kubernetes.helm.v3.Chart resource manages the deployment of the Helm chart to our Kubernetes cluster.
    • We need to provide the actual Helm chart repository URL in the repo field under fetchOpts.
    • We are exporting the kubeconfig at the end, which will be the configuration file needed to connect to your Kubernetes cluster using kubectl or any other Kubernetes management tool.

    Please replace "https://your-helm-chart-repository.com" with the actual URL of the Helm chart repository where keycloak-operator-legacy is hosted and the version with the specific chart version you wish to deploy.

    Remember to configure your Pulumi CLI with the appropriate DigitalOcean API token prior to running this program, since it's assumed that you have already set up the necessary credentials.
