1. Deploy the rh-sso helm chart on Linode Kubernetes Engine


    To deploy the RH-SSO (Red Hat Single Sign-On) Helm chart on Linode Kubernetes Engine (LKE), you will need to create a Kubernetes cluster on Linode, configure kubectl to communicate with your cluster, and then use Pulumi to deploy the Helm chart.

    Here is a Pulumi program written in TypeScript that demonstrates how to perform these tasks. It assumes that you already have a Kubernetes cluster running on Linode and your environment is set up with the necessary credentials to interact with Linode and the Kubernetes cluster.


    1. You will use the @pulumi/kubernetes package to interact with Kubernetes from Pulumi.
    2. The kubernetes.helm.v3.Chart resource from Pulumi Kubernetes provider is ideal for deploying Helm charts.
    3. You will specify the Helm chart for RH-SSO, which should be available in a known Helm chart repository.
    4. The program below does not specify how to obtain the kubeconfig file for your LKE cluster, which you should have obtained when you set up your LKE cluster. You must ensure this kubeconfig is correctly pointed to by the KUBECONFIG environment variable or is located at the default ~/.kube/config path for your Pulumi program to communicate with your Kubernetes cluster.

    Pulumi Program

    import * as kubernetes from "@pulumi/kubernetes"; // Create a provider for the existing Linode Kubernetes cluster. // This assumes that you have a kubeconfig file configured correctly. const provider = new kubernetes.Provider("lke", { kubeconfig: process.env.KUBECONFIG, // Make sure to have this environment variable set }); // Deploy the RH-SSO Helm chart. // Ensure you use the correct 'repo' and 'chart' value for the RH-SSO Helm chart and its specific version if required. const rhSsoChart = new kubernetes.helm.v3.Chart( "rh-sso", { // Replace with the actual repository containing the RH-SSO chart. // The Helm repository URL where the chart is hosted and the chart name should be provided. // As an example, below 'repo' is a placeholder and should be replaced with the actual value. repo: "example-repo", chart: "rh-sso", version: "1.0.0", // specify the chart version here namespace: "default", // specify the namespace where you want to deploy the chart }, { provider: provider, // specify the Kubernetes provider } ); // Export the status URL which might be provided by the RH-SSO Helm chart, if available. // This highly depends on the chart's outputs and needs to be adjusted accordingly. export const statusUrl = rhSsoChart.status.apply(status => status.url);

    Explanation of the Program

    • The provider instance is created to manage resources in your existing Kubernetes cluster on Linode.
    • The rhSsoChart declares a new Helm chart resource to be deployed, which describes the RH-SSO software.
    • The repo property is supposed to contain the URL of the Helm chart repository where the RH-SSO chart is kept. This must be substituted with the actual repository you'd be using.
    • The chart and version properties specify the exact Helm chart and its version you want to deploy.
    • The export statement exposes a URL or any output that the Helm chart provides, making it easily accessible outside of Pulumi. This depends on whether the RH-SSO chart provides such an output.

    Next Steps

    • Install Pulumi CLI on your machine if you haven't already.
    • Use pulumi login to connect to the Pulumi service.
    • Create a new Pulumi project or use an existing one.
    • Add the above code to your Pulumi program file (typically index.ts).
    • Install the required NPM packages by running npm install in your project directory.
    • Run pulumi up to preview and deploy the changes.

    Please ensure you replace placeholders like example-repo with appropriate values for repo and other relevant configuration properties that match the RH-SSO Helm chart you're deploying. This might involve also setting other Helm values specific to RH-SSO which are not covered in this general example.
