Deploy the monitoror helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the Monitoror Helm chart on the Linode Kubernetes Engine (LKE), you would first need a running Kubernetes cluster on Linode. Then you would use the Pulumi Kubernetes provider to install the Helm chart onto your cluster.

I will guide you through the process and provide a Pulumi program written in TypeScript to accomplish this.

Prerequisites

Before running the Pulumi code, ensure the following prerequisites are met:

You have an account with Linode and have access to the Linode Kubernetes Engine.
You have created a Kubernetes cluster in the Linode Cloud Manager and have downloaded the corresponding kubeconfig file.
You have Pulumi CLI installed and configured to use your Linode account credentials.
You have Helm CLI installed and have added the repository that contains the Monitoror chart.
You have Node.js and NPM installed to execute the TypeScript program.

Detailed Explanation

The Pulumi program will:

Use the Pulumi Kubernetes provider to interact with your Kubernetes cluster.
Deploy the Monitoror Helm chart to your Linode Kubernetes cluster using Pulumi's helm.v3.Chart resource.

Here is the program that performs the deployment of the Monitoror Helm chart on LKE:

import * as k8s from "@pulumi/kubernetes";

// Replace '<YOUR-KUBECONFIG-PATH>' with the path to your kubeconfig file.
const kubeconfig = '<YOUR-KUBECONFIG-PATH>';

// The kubeconfig file allows you to authenticate with your Kubernetes cluster.
const provider = new k8s.Provider("lke_k8s", {
    kubeconfig: kubeconfig,
});

// Replace the details below according to the Monitoror Helm chart requirements.
const monitororChart = new k8s.helm.v3.Chart("monitoror", {
    chart: "monitoror",
    // You may need to specify the Helm chart version you wish to deploy.
    version: "x.y.z",
    // Provide any custom settings you wish to modify from the default Helm chart values.
    values: {},
    fetchOpts: {
        // Specify the repository for Monitoror Helm chart.
        repo: "http://path-to-monitoror-chart-repository",
    },
}, { provider: provider });

// Exporting the Kubernetes resources created by the Helm chart for easy access.
export const monitororResources = monitororChart.resources;

Please replace the placeholders with the appropriate values:

<YOUR-KUBECONFIG-PATH>: The file path of your kubeconfig downloaded from the Linode Cloud Manager.
"x.y.z": The version of the Monitoror Helm chart you want to deploy.
"http://path-to-monitoror-chart-repository": The URL to the Helm repository where the Monitoror chart is hosted.

Running the Program

To run this Pulumi program, follow these steps:

Save the TypeScript code to a file named index.ts in a new directory.
Run npm init -y in the directory to create a package.json file.
Install the necessary Pulumi package dependencies by running npm install @pulumi/kubernetes.
Run pulumi up to preview and deploy the changes to your Linode Kubernetes cluster.

When you execute pulumi up, Pulumi will interact with your Linode Kubernetes cluster and deploy the Monitoror Helm chart as specified in the program. After the deployment, the Monitoror dashboard should be running on your LKE cluster. You can use the exported resources to find the deployed services and access your Monitoror dashboard.

Remember to review the Helm chart's documentation for specific configuration options and adjust the values field in the monitororChart object accordingly.
