1. Deploy the keycloak-helm-chart helm chart on Opensshift

    TypeScript

    To deploy the keycloak-helm-chart on OpenShift using Pulumi, you'll need to have an OpenShift cluster already set up and running. I'll show you the necessary steps to deploy a Helm chart into that cluster using Pulumi's Kubernetes provider. You can find more documentation and resources on Kubernetes and Helm in Pulumi over at the Kubernetes and Helm chart deployment sections of the Pulumi documentation.

    Prerequisites:

    Before running the Pulumi program, make sure you have the following:

    • An OpenShift cluster where you will deploy Keycloak.
    • kubectl configured to connect to your OpenShift cluster.
    • Helm chart details for Keycloak. Usually, you can find these in the official chart repositories or the Keycloak documentation.

    Pulumi Program Explained:

    First, we'll import the necessary modules from the Pulumi Kubernetes provider:

    // Import the required Pulumi and Kubernetes packages. import * as k8s from "@pulumi/kubernetes";

    Next, we'll write the code that will create a Chart resource which represents the Keycloak Helm chart. We'll also specify any custom values we need to configure Keycloak precisely as needed:

    // Create a new Kubernetes Chart. const keycloakChart = new k8s.helm.v3.Chart("keycloak", { // Replace with the appropriate chart values chart: "keycloak", version: "<chart version>", fetchOpts: { repo: "https://codecentric.github.io/helm-charts", // This is the repository where the Keycloak chart can be found, replace if different. }, // specify the namespace where Keycloak should be installed namespace: "keycloak", // If necessary, provide the custom values to the chart values: { // Custom values go here (e.g., replicas, service type, etc.) }, });

    In the above Chart declaration, you replace <chart version> with the specific chart version you want to deploy. Also, adapt the namespace field to match where you want to deploy the keycloak cluster if you have specific requirements such as persistence settings or specific replicaCount. You would define that within the values field. Note that repo should point to the URL of the chart's repository.

    Make sure you have the @pulumi/kubernetes npm package installed in your project:

    npm install @pulumi/kubernetes

    Complete Pulumi Program:

    Below is a complete Pulumi program in TypeScript that deploys the Keycloak Helm chart on OpenShift. This program assumes you've already configured Pulumi to use your Kubernetes cluster and the OpenShift context:

    import * as k8s from "@pulumi/kubernetes"; const keycloakChart = new k8s.helm.v3.Chart("keycloak", { chart: "keycloak", version: "<chart version>", fetchOpts: { repo: "https://codecentric.github.io/helm-charts", }, namespace: "keycloak", values: { // Custom values for the Keycloak deployment // Example value: // replicaCount: 1, }, });

    Running the Pulumi Program:

    1. Ensure pulumi CLI is installed and you're logged into a Pulumi account.

    2. Place the Pulumi TypeScript program in a directory, and ensure you have initialized a new Pulumi project.

    3. Install the necessary node modules:

      npm install

    4. Run the Pulumi program to deploy the Keycloak chart to your OpenShift cluster:

      pulumi up

    This Pulumi program will deploy Keycloak using the specified Helm chart into your OpenShift cluster. You can monitor the output in your terminal to see the progress, and once the deployment is complete, you'll get output indicating the success of the deployment. You can then proceed to manage Keycloak within your OpenShift environment.

    Remember to always verify the chart values and version based on your specific deployment requirements for Keycloak. Also, consult the Keycloak Helm chart's values.yaml file for all configurable options to tailor the deployment to your needs.
