1. Deploy the quarkus helm chart on Linode Kubernetes Engine


    To deploy the Quarkus Helm chart on Linode Kubernetes Engine, you need to have a Kubernetes cluster running on Linode and a Pulumi program to manage the deployment of the Helm chart. Here's a comprehensive guide to help you through the process:


    Before proceeding, make sure you have:

    • An active Linode account
    • A Kubernetes cluster set up on Linode Kubernetes Engine (LKE)
    • kubectl configured to interact with your LKE cluster
    • Pulumi CLI installed on your local machine
    • Your Pulumi stack is logged in and set up. If not, you can follow Pulumi's getting started guide for setting up Pulumi and creating a new project

    Understanding Pulumi Resources Used

    In the Pulumi program, we'll use the following Pulumi resource:

    • kubernetes.helm.sh/v3.Chart: This resource is used to deploy a Helm chart into a Kubernetes cluster. Helm is a package manager for Kubernetes, and it allows us to install, upgrade, and manage Kubernetes applications.

    Pulumi currently supports deploying Helm charts using the Helm v3 client, which is reflected in our resource choice.

    Deploying Quarkus Helm Chart with Pulumi

    Now let's write the Pulumi TypeScript program to deploy the Quarkus Helm chart:

    import * as k8s from "@pulumi/kubernetes"; // Step 1: Create an instance of Chart class to deploy Quarkus Helm chart. const quarkusChart = new k8s.helm.v3.Chart("quarkus", { // Assuming you're using a chart sourced from a Helm repository, you should specify the repo URL. // Here we are using a placeholder URL as an example. You'll need to specify the actual URL of the Quarkus Helm chart. repo: "https://your-repo-url", chart: "quarkus", version: "chart-version", // Replace with the version you want to deploy // `values` specifies the values used to configure the deployment. values: { // Configure your values according to the specific needs of Quarkus chart // Example could be the service type, number of replicas, etc. // Below is a placeholder for configuration values. // service: { // type: "ClusterIP" // }, // replicaCount: 2, }, }); // Optional: Export any resource properties you may want to access later. // For example, you could export the Quarkus service endpoint if your chart exposes any service. // export const quarkusServiceEndpoint = quarkusChart.getResourceProperty("v1/Service", "quarkus-service", "status").apply(status => status.loadBalancer.ingress[0].ip);

    Detailed Explanation of What We're Doing:

    1. We import the Kubernetes package provided by Pulumi which includes the necessary classes and functions to interact with Kubernetes resources.
    2. We create an instance of the Chart class representing the Quarkus Helm chart, which Pulumi will deploy to the connected Kubernetes cluster.
    3. You must provide the repo value that points to the repository where the Quarkus Helm chart is hosted. Replace "https://your-repo-url" with the actual repository URL.
    4. Specify the chart and version for the Quarkus Helm chart. The version string should match an actual chart version you want to deploy.
    5. The values object allows you to customize the Helm chart's settings; you'll need to provide the actual configuration values suitable for the Quarkus application deployment.

    Remember to replace the placeholders, like https://your-repo-url and chart-version, with actual information relevant to the Quarkus Helm chart you're deploying.

    Next Steps

    After writing your Pulumi program, you can deploy the Helm chart to your LKE cluster with the following steps:

    1. Run pulumi up in the directory containing your Pulumi program. This will start the deployment process.
    2. Review the plan shown by Pulumi. If everything looks correct, confirm the deployment to proceed.
    3. Pulumi will perform the necessary actions to deploy the Quarkus Helm chart to your LKE cluster.

    Please ensure your Pulumi stack is configured to use the correct Kubernetes context, which should be set to manage your LKE cluster. You can configure this with pulumi config set kubernetes:context <your LKE context> if required.

    After the deployment, you can manage, update, or delete the application using Pulumi CLI's various commands.
