1. Deploy the simple-keycloak helm chart on Oracle Kubernetes Engine (OKE)

    TypeScript

    To deploy the simple-keycloak Helm chart on Oracle Kubernetes Engine (OKE) using Pulumi, you would need to set up the following things:

    1. Oracle Kubernetes Engine Cluster: A Kubernetes cluster provided by OKE where your Helm chart will be deployed.
    2. Helm Chart Deployment: You will use Pulumi's Kubernetes provider to manage resources on Kubernetes, specifically Helm charts.

    The Pulumi program below does the following:

    • It initializes a connection with your OCI (Oracle Cloud Infrastructure) environment using your specified Kubernetes cluster configuration. For this example, we'll assume you already have an OKE cluster provisioned.
    • It then uses the Chart resource from the Pulumi Kubernetes package to deploy the simple-keycloak chart from its Helm repository.

    Let's write the Pulumi program to accomplish this:

    import * as k8s from "@pulumi/kubernetes"; // Initialize the Pulumi Kubernetes Provider for Oracle // This utilizes your existing Oracle Kubernetes Engine (OKE) cluster // Make sure you've configured your Oracle cloud provider settings correctly, // including the generation of a kubeconfig file for accessing your OKE cluster. const provider = new k8s.Provider("oke-k8s", { kubeconfig: "<Your OKE cluster kubeconfig>", }); // Deploy simple-keycloak Helm chart const chart = new k8s.helm.v3.Chart("simple-keycloak", { chart: "simple-keycloak", // Specify the repository where simple-keycloak is located // If the simple-keycloak chart is located in a specific Helm repository // You would add it using the 'repo' parameter like: // repo: "https://charts.example.com/", // For this example, the chart repository is not specified. // Ensure that the repo URL is correct and the chart is available in the repo. version: "latest", // Specify the chart version namespace: "default", // Specify the namespace to deploy to }, { provider }); // Export the public URL for Keycloak if available export const keycloakUrl = chart.getResourceProperty("v1/Service", "default", "simple-keycloak-http", "status").apply(status => { const ingress = status.loadBalancer.ingress[0]; if (ingress) { return ingress.ip || ingress.hostname; } });

    Please replace <Your OKE cluster kubeconfig> with the kubeconfig content or filepath for your OKE cluster. You also need to make sure that the Helm repository containing the simple-keycloak chart is set up correctly if it's not in the default Helm repository.

    The getResourceProperty function is used to retrieve the external IP or hostname of the Keycloak service if it's exposed publicly. It assumes that the chart creates a service of type LoadBalancer. If your service presents a different kind of endpoint, this part of the program should be adjusted accordingly.

    To use this program, save it to a index.ts file in a new Pulumi project. Ensure you have the Pulumi CLI installed, and OCI configured correctly on your system. Run pulumi up to create the resources defined in the Pulumi program.
