1. Deploy the kubernetes-pipeline helm chart on Linode Kubernetes Engine


    To deploy a Helm chart to a Kubernetes cluster using Pulumi, you would typically do the following:

    1. Set up the Pulumi Kubernetes provider to communicate with your Kubernetes cluster.
    2. Use the Helm Chart resource in Pulumi to deploy your desired chart to the cluster.

    Below, I'll guide you step-by-step on how to deploy the kubernetes-pipeline Helm chart to a Linode Kubernetes Engine (LKE) cluster.

    First, you must have access to a Linode Kubernetes Engine cluster and have the kubeconfig file that allows you to communicate with your Kubernetes cluster. This kubeconfig file must be set up on the machine where you're running Pulumi. Pulumi uses this kubeconfig file to communicate with your LKE cluster.

    Next, we'll write a Pulumi program in TypeScript to install the kubernetes-pipeline Helm chart on the cluster:

    Step 1: Installing the Pulumi CLI and setting up your project

    Before we begin, ensure that you have installed the Pulumi CLI and set up your Pulumi project. Follow the Pulumi documentation on how to do it here:

    Step 2: Writing the Pulumi Program

    Here's a TypeScript Pulumi program to deploy the kubernetes-pipeline Helm chart:

    import * as k8s from '@pulumi/kubernetes'; // The configuration for deployment const helmChartName = 'kubernetes-pipeline'; const helmChartVersion = '1.0.0'; // replace this with the actual chart version you want to deploy const namespace = 'default'; // replace with the namespace where the chart should be deployed // Create an instance of the Kubernetes provider based on the kubeconfig. const provider = new k8s.Provider('lke-k8s-provider', { kubeconfig: '<Your Linode kubeconfig here>', }); // Deploy the kubernetes-pipeline Helm chart using the Kubernetes provider. const pipelineChart = new k8s.helm.v3.Chart(helmChartName, { chart: helmChartName, version: helmChartVersion, namespace: namespace, }, { provider }); // Export the Helm chart name and status export const chartName = pipelineChart.chart; export const chartStatus = pipelineChart.status;

    Replace '<Your Linode kubeconfig here>' with the contents of your kubeconfig from Linode, or alternatively make sure your kubeconfig is configured correctly in your environment so Pulumi can automatically use it.

    Step 3: Executing the Pulumi Program

    To deploy the Helm chart to your LKE cluster, execute the following commands in your terminal:

    pulumi up

    This command will prompt Pulumi to perform an update, showing you a preview of the resources that will be created. After reviewing the changes, you can confirm the deployment, and Pulumi will proceed to install the Helm chart on your LKE cluster.

    What does the code do?

    • It starts by importing the necessary Kubernetes package from the Pulumi SDK.
    • We define some constants that configure the Helm chart deployment, such as the chart name, version, and namespace.
    • We create a Provider instance, which tells Pulumi how to communicate with our LKE cluster by providing the kubeconfig.
    • Then, we declare a Chart resource, which represents the Helm chart we wish to install. We pass in the chart configuration and associate it with the provider we just set up.
    • Finally, we export the Helm chart's name and status for easy access.

    Now you have a Pulumi program that will deploy the kubernetes-pipeline Helm chart to your Linode Kubernetes Engine cluster. Remember to handle your kubeconfig securely and remove any sensitive data before sharing your Pulumi program.
