1. Deploy the tekton-pipelines helm chart on Linode Kubernetes Engine


    To deploy the Tekton Pipelines Helm chart on Linode Kubernetes Engine using Pulumi, you'll first need a Kubernetes cluster running on Linode. We will be using Pulumi's Kubernetes provider to interact with your Kubernetes cluster and deploy the Helm chart.

    Here's a step-by-step guide on how you can accomplish this:

    1. Set up the Linode Kubernetes Engine (LKE) cluster using Pulumi.
    2. Install the Tekton Pipelines Helm chart into the LKE cluster.


    Before you begin, ensure that you have:

    • A Linode account with the necessary permissions to create a Kubernetes cluster.
    • The Pulumi CLI installed and configured with your Linode API token (Instructions can be found in the Pulumi documentation).
    • Helm CLI installed on your machine for managing Helm chart deployments (Optional, as Pulumi can manage Helm charts directly).

    Step 1: Setting up the LKE Cluster with Pulumi

    Firstly, we will use Pulumi to create an LKE cluster. For this, we will either need to import an existing cluster or create a new one.

    Step 2: Deploying Tekton Pipelines Helm Chart using Pulumi

    After setting up your Kubernetes cluster, you can deploy the Tekton Pipelines Helm chart using the kubernetes.helm.v3.Chart resource. You will need to specify the chart name and the repository where the chart is located.

    Here's a complete Pulumi program in TypeScript that demonstrates both steps:

    import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; import * as linode from "@pulumi/linode"; const clusterName = "tekton-pipelines-cluster"; const k8sVersion = "1.20"; // Use a supported Kubernetes version for LKE // Step 1: Create a new LKE cluster const cluster = new linode.LkeCluster(clusterName, { k8sVersion: k8sVersion, region: "us-central", tags: ["pulumi-lke"], nodePools: [{ count: 1, type: "g6-standard-2", // g6-standard-2 is a node type with 2 vCPUs and 4GB RAM }], }); // Step 2: Configure the Kubernetes provider to use the kubeconfig from the created LKE cluster const k8sProvider = new k8s.Provider("k8sProvider", { kubeconfig: cluster.kubeconfigRaw, }); // Tekton Helm chart repository url const tektonRepoUrl = "https://tekton.dev/charts"; // Step 3: Deploy the Tekton Pipelines Helm chart const tektonPipelinesChart = new k8s.helm.v3.Chart("tekton-pipelines", { repo: "tekton", // The repo name, as it is in the Helm repository chart: "tekton-pipelines", version: "0.24.1", // Specify the version of the Tekton chart you want to deploy namespace: "tekton-pipelines", // The namespace for deploying the Tekton chart }, { provider: k8sProvider }); // Export the kubeconfig to access the cluster using `kubectl` export const kubeconfig = cluster.kubeconfigRaw;

    Ensure that you replace k8sVersion with a version that is supported by Linode at the time you run this.

    Understanding the Code

    • The linode.LkeCluster() function creates a new LKE cluster with a given Kubernetes version and a node pool configuration.
    • The k8s.Provider() establishes the Pulumi provider for Kubernetes, which allows Pulumi to interact with your Kubernetes cluster.
    • We specify the name of the repo (tekton) and the chart (tekton-pipelines) for the Tekton Pipelines Helm chart. This way, Pulumi knows where to find the chart.
    • We also provide a version number to ensure you deploy the exact version of Tekton Pipelines you want.
    • We set the namespace for isolating Tekton Pipelines within the Kubernetes cluster.

    Running the Program

    To run this Pulumi program:

    1. Save the code to a file with a .ts extension, say index.ts.
    2. Run pulumi up in the same directory as your code file. Pulumi will perform the deployment, creating an LKE cluster and deploying the Tekton Pipelines Helm chart.

    You can monitor the deployment status directly through the Pulumi CLI, and once completed, the given kubeconfig output can be used to connect to your Kubernetes cluster with kubectl.

    Keep in mind that you might incur costs from Linode for the resources created with Pulumi, and you should destroy the resources with pulumi destroy once you no longer need them to avoid unnecessary charges.
