Deploy the zotero helm chart on Oracle Kubernetes Engine (OKE)

To deploy the Zotero Helm chart on Oracle Kubernetes Engine (OKE), you need to follow a series of steps. Helm charts are used to package and deploy applications on Kubernetes clusters, and Oracle Kubernetes Engine is Oracle's managed Kubernetes service, which simplifies the process of running a Kubernetes cluster.

Below is a high-level overview of what we're going to do:

1. Set up the Kubernetes provider to interact with your OKE cluster.
2. Use the Pulumi Kubernetes provider to deploy a Helm chart for Zotero.

Here's the Pulumi code written in TypeScript to meet the deployment requirement. This program assumes you have the necessary access to the Oracle Kubernetes Engine (OKE), and have set up the kubeconfig file to access your Kubernetes cluster.

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

// Get the Kubeconfig for the OKE cluster.
// This could also be sourced from an external configuration.
const kubeconfig = "path-to-your-kubeconfig-file";

// Create a Kubernetes provider instance using the cluster kubeconfig.
const provider = new k8s.Provider("okeProvider", {
    kubeconfig: kubeconfig,
});

// Deploy the Zotero Helm chart on the OKE cluster.
// The Helm chart must be located in a Helm repository, and you need to provide the correct chart name and version.
const zoteroHelmChart = new k8s.helm.v3.Chart("zotero", {
    chart: "zotero",
    version: "chart-version", // Replace with the chart version you want to deploy
    // If your chart requires you to override default values, specify them here.
    // values: {
    //     replication: {
    //         count: 3,
    //     },
    //     service: {
    //         type: "LoadBalancer",
    //     },
    // },
}, { provider });

// Export any pertinent information, such as the load balancer IP or hostname for accessing the application.
export const zoteroEndpoint = zoteroHelmChart.getStatus("v1/services", "zotero").apply(status => {
    return status.loadBalancer.ingress[0].ip || status.loadBalancer.ingress[0].hostname;
});

In this program:

• We create a new Pulumi provider for Kubernetes, enabling Pulumi to interact with the OKE Kubernetes cluster. You need to replace the kubeconfig variable with the path to your cluster's kubeconfig file.

• We then deploy the Zotero Helm chart to the cluster using Pulumi's Helm chart resource. You will need to specify the correct Helm chart repository or have it available locally. In this example, the chart parameter should be the name of the Zotero chart as recognized by Helm and version should be the chart version you wish to deploy. If the chart is not publicly available, you might need to add properties like repo to specify the repository URL.

• Optionally, if you need to provide custom values to the Helm chart to configure Zotero, you can specify an object with your configuration to the values property.

• Finally, we export an endpoint that could be used to access the Zotero service. This step might differ based on how Zotero and its associated services are exposed from the Helm chart.

Make sure to replace the placeholder values with the actual details for your cluster and Helm chart information. If Zotero requires configuration parameters specific to your environment or preferences, include them in the values object that is commented out.

Before running this Pulumi program, you should install Pulumi and set up the Oracle Cloud Infrastructure (OCI) provider. Execute pulumi up to deploy the resources. After deploying, you can get the Zotero endpoint by running pulumi stack output zoteroEndpoint.
