1. Deploy the quickwit helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the Quickwit Helm chart on the Linode Kubernetes Engine (LKE), you'll need to create a Linode Kubernetes cluster, configure kubectl to connect to it, and then use Helm to deploy Quickwit. Below is a comprehensive guide to help you achieve this using Pulumi, which is an Infrastructure as Code (IaC) tool.

    Firstly, you'll need to install the Pulumi CLI and set up your Linode API token as per the Pulumi with Linode instructions.

    Once you have Pulumi set up, you can use the @pulumi/linode package to create a Kubernetes cluster in Linode. After the cluster is created, you can configure your local kubectl with the generated Kubeconfig to interact with your new cluster. You'll then be able to use Helm to deploy Quickwit.

    Here’s a step-by-step Pulumi TypeScript program to accomplish the deployment:

    1. Setup the required Linode provider and Kubernetes packages.
    2. Define a new Kubernetes cluster on Linode.
    3. Obtain the Kubeconfig after the cluster is provisioned.
    4. Use Helm to deploy your Quickwit chart on the new cluster.
    import * as pulumi from "@pulumi/pulumi"; import * as k8s from "@pulumi/kubernetes"; import * as linode from "@pulumi/linode"; // Step 1: Create a new Linode Kubernetes cluster. const cluster = new linode.LkeCluster("quickwit-cluster", { region: "us-central", // Pick the region that best suits you k8sVersion: "1.23", // Use a compatible Kubernetes version for Quickwit nodePools: [{ count: 2, // Define the size of your cluster type: "g6-standard-2", // Select the type of node }], }); // Step 2: Generate the Kubeconfig for the cluster. const kubeconfig = pulumi.all([cluster.id, cluster.kubeconfig]).apply(([_, kubeconfig]) => { return kubeconfig; }); // Use the generated Kubeconfig to interact with the cluster via kubectl. const provider = new k8s.Provider("quickwit-provider", { kubeconfig: kubeconfig, }); // Step 3: Deploy Quickwit Helm chart. // Replace '<your-quickwit-chart-repo>' with the actual Helm chart repository URL. // Replace '<chart-name>' with the name of the chart in the repository. const quickwitChart = new k8s.helm.v3.Chart("quickwit-chart", { chart: "<chart-name>", version: "0.1.0", // Use the specific chart version you need fetchOpts:{ repo: "<your-quickwit-chart-repo>" // The repository where your chart is located. }, }, { provider }); // Stack exports export const kubeconfigOutput = kubeconfig;

    Important Points:

    • The linode.LkeCluster resource is used to create a Linode Kubernetes cluster.
    • region and type should be selected according to your geographical and performance needs.
    • The k8s.helm.v3.Chart resource is used to deploy Helm charts. You need to specify the chart name and repository URL appropriately.
    • We're exporting the kubeconfigOutput, which you will use to connect to the Kubernetes cluster using kubectl or other Kubernetes tooling.

    Remember to replace <your-quickwit-chart-repo> with the URL of the Helm repository where the Quickwit Helm chart is hosted and <chart-name> with the actual chart name.

    To apply this Pulumi program, save the code into a file (e.g. index.ts), ensure that you've installed all the required npm packages with npm install, and then run pulumi up from the terminal in the directory where your index.ts resides.

    After running pulumi up, Pulumi performs the deployment of the resources declared in the program. It creates a Kubernetes cluster in Linode, configures the Kubeconfig, and deploys the Quickwit Helm chart to that newly created cluster.

    Verify the deployment using kubectl with the Kubeconfig file that Pulumi outputs to ensure Quickwit was deployed successfully.

    Please review the Pulumi Linode documentation for detailed information on how to set up and configure Pulumi to work with Linode, and the Pulumi Kubernetes documentation to learn more about creating Kubernetes resources.
