1. Deploy the openrefine helm chart on Kubernetes


    To deploy the OpenRefine Helm chart on a Kubernetes cluster using Pulumi, you will need to use Pulumi's Kubernetes provider to manage Kubernetes resources directly. The Helm chart will be encapsulated in a Chart resource, which Pulumi will use to apply the chart to your cluster.

    Below is a TypeScript Pulumi program that deploys the OpenRefine Helm chart. The kubernetes.helm.v3.Chart resource represents a Helm chart that Pulumi will deploy to your Kubernetes cluster. This resource expects several properties, such as chart to specify the chart name, version to specify the chart version, and values to provide custom values for the Helm chart.

    For OpenRefine, the Helm chart might be available in a community Helm repository, so you would need to add that repository URL to the repo property. The values object could be used to customize the installation, but in this basic example, we're using the default values provided by the Helm chart.

    Here's a simplified example of deploying OpenRefine with default values:

    import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Kubernetes Helm Chart class. const openRefineChart = new k8s.helm.v3.Chart("openrefine", { // The repository where the OpenRefine Helm chart is located. repo: "https://repository/url/for/openrefine", // Replace with the actual repository URL // The name of the chart. chart: "openrefine", // Specify the version of the chart you wish to deploy. version: "1.0.0", // Replace with the actual chart version // Provide any custom values to the Helm chart. values: { // If the chart requires any custom values, specify them here. // For example: // service: { // type: "LoadBalancer" // }, }, // If needed, you could specify the Kubernetes namespace to deploy into. // Otherwise, it will be deployed into the default namespace. // For example, to deploy into the "default" namespace: namespace: "default", }); // To access the values of the deployed resources, such as IP addresses or hostnames, // you can export these values using the following format: export const openRefineServiceIP = openRefineChart.getResourceProperty("v1/Service", "openrefine", "status").apply(status => status.loadBalancer.ingress[0].ip);

    This program imports the Kubernetes package from Pulumi's library (@pulumi/kubernetes). Then it creates a Helm chart resource with the name openrefine, specifying the Helm chart's repository, chart name, version, and any values overrides. It also specifies the Kubernetes namespace for deployment.

    If your Helm chart exposes a service with an external IP (typically when using a service of type LoadBalancer), you might want to export this IP so you can easily obtain it after deployment. The getResourceProperty method retrieves properties of resources, and we're using apply to access the nested properties of the load balancer IP address. If your service uses a different setup (like a NodePort or an Ingress), you would need to adjust this part accordingly.

    Note: Be sure to replace "https://repository/url/for/openrefine" with the actual URL of the Helm repository that contains the OpenRefine chart, and adjust the version with the chart version you want to deploy. The values object is where you would place any configuration overrides specific to the OpenRefine Helm chart; since this is a simplified example, it's left blank, assuming the defaults are fine for your use case.
