1. Deploy the keycloak-helm-chart helm chart on AWS EKS


    To deploy the keycloak-helm-chart on an AWS EKS cluster, we'll need to follow these steps:

    1. Set up an AWS EKS cluster where Keycloak will be deployed.
    2. Create an instance of the Helm Chart for Keycloak, specifying any configurations as necessary.

    We'll be using the following resources from Pulumi:

    • eks.Cluster: This resource will create the necessary infrastructure for an AWS EKS cluster. Read the docs.
    • kubernetes.helm.v3.Chart: This resource is used to deploy Helm charts, which is a package management solution for Kubernetes applications. We'll deploy Keycloak using this Helm chart resource. Read the docs.

    Here's the TypeScript Pulumi program for deploying Keycloak on AWS EKS:

    import * as eks from "@pulumi/eks"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("my-keycloak-cluster", { desiredCapacity: 2, minSize: 1, maxSize: 3, // Specify additional settings as required for the EKS cluster. }); // Once the cluster is created, we can configure our k8s provider to use the cluster's kubeconfig. const provider = new k8s.Provider("my-keycloak-provider", { kubeconfig: cluster.kubeconfig.apply(JSON.stringify), }); // Deploy Keycloak using the Helm chart. const keycloakChart = new k8s.helm.v3.Chart("keycloak", { chart: 'keycloak', version: 'x.y.z', // Replace this with the desired chart version namespace: 'keycloak', // Specify the namespace or use the default one fetchOpts:{ repo: "https://codecentric.github.io/helm-charts", // The repo URL where the chart can be found }, // Specify your Keycloak configurations within values values: { keycloak: { // Specify Keycloak configurations here }, }, }, { provider }); // Export the cluster's kubeconfig and the Keycloak load balancer URL. export const kubeconfig = cluster.kubeconfig; export const keycloakUrl = keycloakChart.getResourceProperty('v1/Service', 'keycloak', 'status').apply(status => status.loadBalancer.ingress[0].hostname);

    In the above program:

    • The EKS cluster is initialized with basic scaling configurations. You can modify desiredCapacity, minSize, and maxSize depending on your use case.
    • The Kubernetes provider uses the kubeconfig from the newly created EKS cluster, allowing us to deploy resources to that cluster.
    • We define a Helm chart for Keycloak, specifying the repository URL and the chart version.
    • We export the Kubernetes configuration (kubeconfig) and the hostname of the Keycloak service (assuming it's exposed via a LoadBalancer).

    Remember to replace 'x.y.z' with the actual version of the Helm chart you want to deploy. You may also need to specify additional Keycloak configurations within the values section to suit your needs.

    Also, Keycloak should be configured with a persistent data store. This example assumes you are using the chart's defaults or have a suitable external configuration. Please consult the Keycloak Helm Chart documentation for detailed configuration options, particularly around persistence and database settings.

    To deploy this program:

    1. Ensure you have Pulumi CLI installed and your AWS credentials configured.
    2. Place this program in a new directory.
    3. Run pulumi up from within that directory.
    4. Apply appropriate settings as suggested by the CLI interactions during the deployment process.
