1. Deploy the Wordress helm chart on Linode Kubernetes Engine

    TypeScript

    To deploy the WordPress Helm chart on Linode Kubernetes Engine using Pulumi, you'll need to first set up your Linode Kubernetes Engine (LKE) cluster and then use the Helm chart resource to deploy WordPress onto your cluster.

    First, you must have the Pulumi CLI installed and configured with Linode access credentials appropriately set up. Pulumi interacts with your cloud provider using the credentials configured for that cloud. For Linode, you can set the access token in your environment variables, like so: LINODE_TOKEN=your-token-here.

    Next, we'll outline the basic steps you need to follow in this program:

    1. Set up the Linode Kubernetes Engine (LKE) cluster using Pulumi's Linode provider.
    2. Use the Kubernetes provider to interact with your LKE cluster.
    3. Deploy WordPress using the Helm chart resource provided by Pulumi's Kubernetes provider.

    Here's a complete TypeScript program for deploying WordPress on an LKE cluster:

    import * as linode from "@pulumi/linode"; import * as k8s from "@pulumi/kubernetes"; import * as pulumi from "@pulumi/pulumi"; // Step 1: Create a Linode Kubernetes Engine cluster const cluster = new linode.LkeCluster("my-wordpress-cluster", { region: "us-central", // You can choose the region that is close to you k8sVersion: "1.22", // Specify your desired Kubernetes version tags: ["pulumi-lke"], // Define node pools (groups of machines with the same configuration) pools: [{ count: 2, // Number of nodes in the pool type: "g6-standard-2" // Node type, this is a standard node with 2CPU and 4GB RAM }], }); // Step 2: Configure Kubernetes provider to use the kubeconfig from the generated cluster const kubeConfig = cluster.kubeconfig.apply(JSON.parse); const k8sProvider = new k8s.Provider("k8s-provider", { kubeconfig: kubeConfig.rawConfig, }); // Step 3: Deploy WordPress Helm Chart to the LKE cluster using Helm provider const wordpress = new k8s.helm.v3.Chart("wp-chart", { chart: "wordpress", version: "11.1.5", // You might want to use the latest version that suits your needs fetchOpts: { repo: "https://charts.bitnami.com/bitnami", }, }, { provider: k8sProvider }); // Export the Kubeconfig and WordPress service endpoint to access your WordPress deployment export const kubeconfigOutput = kubeConfig.rawConfig; export const wordpressEndpoint = wordpress.getResource("v1/Service", "default/wp-chart-wordpress").status.apply(s => s.loadBalancer.ingress[0].ip);

    Let's break down this program step by step:

    1. We import the required Pulumi packages for Linode (@pulumi/linode), Kubernetes (@pulumi/kubernetes), and the core Pulumi library (@pulumi/pulumi).

    2. We define a new Linode Kubernetes Engine cluster resource called my-wordpress-cluster with the desired configuration such as region, Kubernetes version, and the node pool specifying the number and type of nodes using linode.LkeCluster.

    3. We then configure a Pulumi Kubernetes provider (k8s.Provider) to interact with our Kubernetes cluster. The provider needs the kubeconfig, which we obtain from the LKE cluster resource.

    4. We deploy WordPress using the Helm chart resource (k8s.helm.v3.Chart). We specify the chart name (wordpress), version, and the repository where the Helm chart is located.

    5. Lastly, we export the kubeconfig for your LKE cluster and the endpoint IP address for the WordPress service, allowing you to interact with your Kubernetes cluster and access your WordPress site after deployment.

    To run this Pulumi program, you'll need to create a new Pulumi project, add this code to the main TypeScript file, run pulumi up, and follow the prompts. After deployment, you can access your WordPress site using the exported service endpoint IP address.
