Deploy the ibm-fhir-server helm chart on Rancher

Question

Pulumi · Accepted Answer

To deploy the IBM FHIR Server helm chart on Rancher using Pulumi, you would typically follow these steps:

Set up a Rancher-managed Kubernetes cluster.
Obtain the IBM FHIR Server helm chart.
Deploy the helm chart to the cluster using Pulumi.

Below is a Pulumi program written in TypeScript that demonstrates how you would set up and deploy the IBM FHIR Server helm chart on a Rancher-managed cluster.

First, we need to create a Rancher-managed Kubernetes cluster. For this example, I'll be using a generic setup. In practice, you would have to tailor the cluster configuration to your specific requirements, such as the node size, the number of nodes, etc.

Next, we will add the Helm Chart repository that contains the IBM FHIR Server chart. Using Rancher's CatalogV2 resource, we can manage catalog repositories.

Lastly, we will deploy the IBM FHIR Server helm chart. Pulumi does not have a direct integration with Helm charts for Rancher deployments in TypeScript, but you could use Kubernetes resources to manage this if you have the helm chart already templated into Kubernetes manifests or if Rancher's API allows Helm chart deployments directly.

Please adjust the following program to suit your actual configuration, particularly the aspects concerning the Kubernetes cluster setup, and make sure that the Helm chart version and parameters match the ones you intend to deploy.

import * as rancher2 from "@pulumi/rancher2";
import * as k8s from "@pulumi/kubernetes";

// Step 1: Provision a new Rancher-managed Kubernetes cluster.
// The following is a placeholder and should be replaced with specific cluster configurations.
const cluster = new rancher2.Cluster("my-cluster", {
    // Define the necessary properties for your cluster configuration.
    // You will need to refer to the Rancher2 documentation for details specific to your cloud provider.
});

// Step 2: Add the Helm chart repository that includes the IBM FHIR Server chart using Rancher CatalogV2 resource.
const catalog = new rancher2.CatalogV2("ibm-fhir-server-catalog", {
    clusterId: cluster.id,
    url: "https://<ibm-fhir-server-helm-chart-repo-url>", // Replace with the actual IBM FHIR Server chart repo URL.
    gitRepo: "<git-repo>", // If the charts are in a git repository, specify it here.
    gitBranch: "<branch-name>", // The branch that contains the chart.
    // Refer to the documentation for additional parameters you might need: https://www.pulumi.com/registry/packages/rancher2/api-docs/catalogv2/
});

// Step 3: Deploy the IBM FHIR Server Helm chart to the cluster.
const fhirServerChart = new k8s.helm.v3.Chart("ibm-fhir-server-chart", {
    chart: "ibm-fhir-server",
    version: "<chart-version>", // Specify the chart version.
    fetchOpts: {
        repo: "https://<ibm-fhir-server-helm-chart-repo-url>", // Replace with the actual IBM FHIR Server chart repo URL.
    },
    // Define values for the chart as needed.
    values: {
        // Specify helm chart values here.
    },
}, { provider: cluster }); // Ensure you provide the Rancher cluster as the Kubernetes provider.

// Export the cluster name and catalog name
export const clusterName = cluster.name;
export const catalogName = catalog.name;

In this code, we've created a basic Rancher-managed Kubernetes cluster and added a new Helm repository via Rancher's catalog feature. Then, we've used the Helm chart to deploy the IBM FHIR Server onto that cluster.

Please replace placeholder values (like <ibm-fhir-server-helm-chart-repo-url>, <chart-version>, <git-repo>, and <branch-name>) with actual values specific to your setup. The fetchOpts block is particularly for when you're adding a Helm chart by URL, while gitRepo and gitBranch are used when the Helm charts are managed in a Git repository.

Before running the code, ensure you have the required Pulumi providers set up in your package.json and that you've logged into your Rancher instance so Pulumi can communicate with it.

Keep in mind that to run the Pulumi code above, you'll need to have Pulumi installed and configured for the appropriate cloud provider. Additionally, since this program is version-agnostic, double-check that the APIs and resource properties match the versions available at the time of your deployment.
