Deploy the zotero helm chart on Linode Kubernetes Engine

To deploy the Zotero Helm chart on Linode Kubernetes Engine using Pulumi, we will follow these steps:

1. Set Up and Configure the Linode Kubernetes Engine (LKE) Cluster: We need a Kubernetes cluster where our Helm chart will be deployed. We will create a new LKE instance using Pulumi's Linode provider.

2. Deploy the Helm Chart: Once we have a Kubernetes cluster, we will use Pulumi's Kubernetes provider to deploy the Zotero Helm chart to the cluster. The kubernetes.helm.v3.Chart resource will be used for this purpose.

Below I'll provide you with a program written in TypeScript that performs these tasks. The program assumes that you have Pulumi installed, have the necessary Linode and Kubernetes configurations in place, and are familiar with running Pulumi commands such as pulumi up to create and update your resources.

Let's begin by creating the LKE instance:

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

// Step 1: Create a Linode Kubernetes Engine cluster
const cluster = new linode.LkeCluster("zotero-cluster", {
    region: "us-central",
    k8sVersion: "1.20",
    label: "zotero-cluster",
    tags: ["pulumi-cluster"],
    pool: [
        {
            type: "g6-standard-2",
            count: 3,
        },
    ],
});

// Export the Kubeconfig and cluster id
export const kubeconfig = cluster.kubeconfig;
export const clusterId = cluster.id;

// Step 2: Deploy the Zotero Helm chart onto the LKE cluster
// We need to use the Kubeconfig generated from our new LKE cluster to interact with it
const k8sProvider = new k8s.Provider("k8s", { kubeconfig: cluster.kubeconfig });

// Deploy the Zotero Helm chart
const zoteroChart = new k8s.helm.v3.Chart("zotero", {
    chart: "zotero",
    version: "1.0.0", // Specify the version of the chart, if known
    fetchOpts: { repo: "https://helm.example.com/" }, // Replace with the Zotero Helm chart's repository URL
}, { provider: k8sProvider });

// (Optional) Export the endpoint to access the Zotero service
export const zoteroServiceEndpoint = zoteroChart.getResourceProperty("v1/Service", "zotero", "status");

Explanation:

• We begin by importing the necessary Pulumi packages for Linode and Kubernetes (@pulumi/linode and @pulumi/kubernetes).

• We instantiate a Linode.LkeCluster to create a new Kubernetes cluster in Linode, specifying the details such as region, Kubernetes version, and the pool of nodes.

• Once the cluster is created, we export the kubeconfig, which will be used to access the LKE cluster programmatically.

• With the Kubeconfig in hand, we set up a Kubernetes provider k8s.Provider, which tells Pulumi how to communicate with our Kubernetes cluster.

• Then, we deploy the Zotero Helm chart using the k8s.helm.v3.Chart resource. We specify the chart name, along with version and the location of the chart's repository fetchOpts.repo. Adjust these values as necessary based on the actual details of the Zotero Helm chart.

• Optionally, we export the service endpoint of the deployed Zotero service. This URL will be useful to access the Zotero application once it's deployed.

Remember, to successfully run this program, you need to replace "https://helm.example.com/" with the correct Helm chart repository URL for Zotero. Additionally, the version 1.0.0 is hypothetical—please use the actual chart version you wish to deploy.

To apply this Pulumi program:

1. Save the code to a file index.ts.
2. Run pulumi stack init to create a new stack.
3. Run pulumi up to execute the program and create the resources.

Please ensure that your Linode provider is configured correctly with the necessary access tokens. You'll also want to ensure that your Pulumi CLI is configured for the correct stack and environment.
