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


    To deploy the keycloak-resources deployment using the keycloak-operator Helm chart on an AWS EKS cluster using Pulumi, you must follow a series of steps:

    1. Create an EKS Cluster: You will need an EKS cluster where Keycloak and its operator will be deployed. The Pulumi EKS package simplifies the creation of an EKS cluster.

    2. IAM Role for EKS: AWS requires an IAM role that EKS can assume to create AWS resources such as Elastic Load Balancers.

    3. Deploy the Helm chart for keycloak-operator: Helm charts help to deploy applications on Kubernetes clusters. The keycloak-operator Helm chart will provision the necessary operator to manage Keycloak instances in the EKS cluster.

    4. Keycloak Resources using keycloak-operator: After deploying the operator, you can define keycloak-resources such as realms, users, or clients using custom resources that the Keycloak operator will manage.

    Below is a detailed program written in TypeScript for use with Pulumi to deploy a Keycloak instance on AWS EKS. Before you run the code, make sure you have the Pulumi CLI installed and configured with the necessary AWS credentials.

    import * as eks from "@pulumi/eks"; import * as aws from "@pulumi/aws"; import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS Cluster // This will create an AWS EKS cluster with default configurations. You may need to adjust // specific configurations like instance types or the number of nodes as per the requirements. const cluster = new eks.Cluster("my-eks-cluster", { // The instanceType to use for the cluster's nodes. Defaults to "t2.medium". instanceType: "t2.medium", // The number of worker nodes that the cluster should initially start with. desiredCapacity: 2, // If you need to specify a specific Kubernetes version, you can add it here. // Otherwise, EKS chooses the default version. version: "1.21", }); // Using the cluster's kubeconfig, create a Kubernetes provider that we'll use for deploying // the Helm chart later in the code. const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy keycloak-operator using the Helm Provider. // Here, we use the Pulumi Kubernetes Provider to interact with the created EKS cluster. // Replace 'my-keycloak-operator' with your preferred release name and 'namespace' with the // namespace you want to deploy into. const keycloakOperatorChart = new k8s.helm.v3.Chart("my-keycloak-operator", { chart: "keycloak-operator", version: "1.0.0", // Replace with the version of the keycloak-operator Helm chart you wish to deploy namespace: "default", // Set the values for the Helm chart as needed. values: { // Custom values for the Helm chart can be set here if needed }, }, { provider: k8sProvider }); // Once the keycloak-operator is installed and running, you can deploy Keycloak resources. // Here's an example of how you could create a Keycloak instance using the keycloak-operator. const keycloakInstance = new k8s.apiextensions.CustomResource("my-keycloak-instance", { apiVersion: "keycloak.org/v1alpha1", kind: "Keycloak", metadata: { namespace: "default", // Ensure this is the same namespace as the operator }, spec: { instances: 1, // Define the specifications for your Keycloak instance here. // You will need to consult the keycloak-operator documentation for the required spec values. }, }, { provider: k8sProvider, dependsOn: [keycloakOperatorChart] }); // Export the cluster's kubeconfig and Keycloak URL export const kubeconfig = cluster.kubeconfig; export const keycloakUrl = pulumi.interpolate`http://${keycloakInstance.status.externalUrl}`;

    This program sets up an AWS EKS cluster, then deploys the keycloak-operator Helm chart into it. After that, it uses the Keycloak operator to create a Keycloak instance. Once the program is executed with pulumi up, it will print out the kubeconfig needed to manage the Kubernetes cluster and the external URL to access Keycloak.

    Make sure to replace 1.0.0 with the actual version of the keycloak-operator Helm chart you wish to deploy and update the kind: "Keycloak" CustomResource with the actual API version and specifications for deploying Keycloak resources.

    The dependsOn option in the Keycloak custom resource makes sure that it is created only after the Keycloak operator has been deployed by the Helm chart.

    Running pulumi up will start the deployment process, and once completed, you should be able to access your EKS cluster and Keycloak URL.
