1. Deploy the keycloak-resources deployment for keycloak-operator helm chart on Opensshift


    To deploy the keycloak-resources deployment for the keycloak-operator Helm chart on an OpenShift cluster, we'll use Pulumi's Kubernetes provider to install the Helm chart and create the necessary resources. Helm charts are packages of pre-configured Kubernetes resources, and the keycloak-operator Helm chart will facilitate the deployment of Keycloak on OpenShift.

    Before you begin, ensure that you have the following prerequisites in place:

    • Pulumi CLI installed.
    • An active OpenShift cluster configured with kubectl.
    • Helm CLI installed (this is only for direct Helm commands, not used in Pulumi, but useful for chart discovery and management).

    In this Pulumi TypeScript program, we will:

    1. Import the necessary Pulumi and Kubernetes packages.
    2. Create a Kubernetes provider instance that Pulumi uses to communicate with your OpenShift cluster.
    3. Use the Chart resource from the Pulumi Kubernetes package to deploy the keycloak-operator Helm chart along with the custom keycloak-resources.

    Here is the complete Pulumi TypeScript program to deploy the keycloak-resources deployment using the keycloak-operator Helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Instantiate the Kubernetes provider targeting the OpenShift cluster // Ensure your kubectl context is set to the proper OpenShift cluster where you want to deploy Keycloak const openshiftProvider = new k8s.Provider("openshiftK8s", { // You might typically need to specify context and kubeconfig here to point to the right cluster if it's not set globally. }); // Step 2: Deploy the keycloak-operator helm chart // Replace the <helm_chart_version> placeholder with the desired version of the Keycloak Operator Helm chart. const keycloakOperatorChart = new k8s.helm.v3.Chart("keycloak-operator", { chart: "keycloak-operator", version: "<helm_chart_version>", fetchOpts: { repo: "https://operatorhub.io/", }, namespace: "keycloak" // You can specify the namespace where you want to install the operator }, { provider: openshiftProvider }); // We assume that the chart will create a CustomResourceDefinition for Keycloak // Here we would typically wait for the CRD to be ready before creating resources of that CRD type // Step 3: Deploy keycloak-resources based on the custom resource definitions provided by the keycloak-operator // This step assumes that the Keycloak Operator provides a CustomResource (CR) for Keycloak. // The deployment would require the creation of such a CR. // As an example, the Keycloak CR may look something like this: const keycloakResources = new k8s.yaml.ConfigFile("keycloak-resources", { file: "path_to_keycloak_resources.yaml", }, { provider: openshiftProvider, dependsOn: [keycloakOperatorChart] }); // Export any necessary properties, such as the Keycloak instance URL or other status fields export const keycloakUrl = keycloakResources.getResourceProperty("v1/Service", "keycloak", "status"); // When running `pulumi up`, Pulumi will perform the deployment to your OpenShift cluster.

    To use this code:

    1. Create a new empty directory on your machine and change to it.
    2. Run pulumi new typescript to create a new Pulumi TypeScript project.
    3. Replace the contents of index.ts with the code provided above.
    4. Replace <helm_chart_version> with the actual version of the Keycloak operator chart you want to use. You can find the chart version using helm search repo command or by visiting the chart repository online.
    5. Create a 'path_to_keycloak_resources.yaml' file with the proper Keycloak CRD manifest content, based on your specific configuration needs. This typically includes your Keycloak instance configuration, such as the number of replicas, external access configuration, and other Keycloak operational settings.
    6. Run pulumi up to deploy the chart to your cluster.

    Please replace placeholders such as <helm_chart_version> and path_to_keycloak_resources.yaml with actual values appropriate for your use case. Also, customize the namespace property if you have a specific namespace where you want to deploy Keycloak. Make sure you have configured Pulumi with access credentials to the cluster and have set up the correct kubectl context.

    If your OpenShift cluster requires specific configurations such as custom context or kubeconfig for Provider, adjust the openshiftProvider initialization accordingly.

    The dependsOn option ensures that the keycloak-resources deployment only proceeds once the Helm chart has been successfully deployed and all the necessary CRDs are available.

    After deployment, the export statement will provide you with the URL of your Keycloak deployment, though you may need to dig into the specific properties for the correct status fields depending on the actual service definition.
