1. Deploy the wazuh helm chart on Linode Kubernetes Engine

    TypeScript

    In order to deploy the Wazuh Helm chart on Linode Kubernetes Engine using Pulumi, you'll need to perform several steps:

    1. Set up a Kubernetes cluster on Linode (if you haven't done so already).
    2. Install Pulumi CLI and configure it to use your Linode Kubernetes cluster.
    3. Write a Pulumi program to deploy the Wazuh Helm chart to your cluster.

    Below, you will find a detailed Pulumi program written in TypeScript that deploys the Wazuh Helm chart to a Linode Kubernetes cluster.

    Before running this program, ensure you have Pulumi CLI installed and configured to manage resources in your Linode account. Also, deploy a Kubernetes cluster in Linode Kubernetes Engine and keep the kubeconfig file ready, as Pulumi will use it to communicate with your Kubernetes cluster.

    Here is a Pulumi program that accomplishes the Wazuh chart deployment:

    import * as k8s from "@pulumi/kubernetes"; // Specify the Wazuh Helm chart repository details. const wazuhChart = new k8s.helm.v3.Chart("wazuh", { chart: "wazuh", version: "4.2.5", // Specify the version of the chart you want to deploy. fetchOpts: { repo: "https://wazuh.github.io/wazuh-charts", // Wazuh Helm chart repository URL. }, values: { // Add any custom values you want to override, for example: // clusterDomain: "cluster.local", }, }); // Export any details you might be interested in, for example, the status of the chart. export const wazuhChartStatus = wazuhChart.status;

    In the snippet above:

    • We start by importing the @pulumi/kubernetes library to interact with Kubernetes-related resources.
    • We then declare a new Helm chart resource using new k8s.helm.v3.Chart.
    • The chart is named "wazuh", which matches with the Wazuh Helm chart. We are also specifying the version of the chart to ensure predictability in our deployments.
    • The fetchOpts.repo field is used to specify the location of the Wazuh Helm chart repository.
    • The values field allows you to override the default configuration options in the Helm chart with your desired settings.
    • Finally, we're exporting the status of the Helm chart deployment with export const wazuhChartStatus, which can be useful for debugging or tracking the application status programmatically.

    Ensure that you replace the version property with the correct version of the Wazuh Helm chart you wish to deploy. You can find the available versions in the Wazuh Helm chart repository.

    To run the program, save it in a TypeScript file (for example, index.ts), then, from your command line within the project's directory, execute:

    pulumi up

    Pulumi will perform a preview, then prompt for confirmation before applying the changes. If confirmed, Pulumi will deploy the specified Helm chart to your Linode Kubernetes cluster.

    Make sure you have the kubeconfig file for your Linode Kubernetes cluster configured on your machine as Pulumi relies on this file to communicate with your cluster. If this file is in the default location (~/.kube/config), Pulumi will use it automatically. If the kubeconfig is in a different location, you can specify its path by setting the KUBECONFIG environment variable.
