Deploy the nginx-files-server helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the nginx-files-server Helm chart on an OpenShift cluster, we will use Pulumi's Kubernetes provider.

First, you would need to have access to an existing OpenShift cluster, which Pulumi will use to deploy resources. If you have not yet connected your Pulumi to your OpenShift instance, please follow the official [Pulumi documentation](https://www.pulumi.com/docs/get-started/kubernetes/) to set up the Kubernetes provider for an OpenShift cluster.

For our task, we will be using the `Chart` resource from the Pulumi Kubernetes Helm package. This resource lets you apply a Helm chart, which is a collection of pre-configured Kubernetes resources, from either a public or private chart repository. In this case, we're assuming that the `nginx-files-server` Helm chart exists and is available in a publicly accessible repository.

Below you'll find a Pulumi TypeScript program that deploys the `nginx-files-server` Helm chart on OpenShift:

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

// The repository where nginx-files-server Helm chart is located
const chartRepo = "https://your-helm-chart-repository.com/";

// The version of the Helm chart you want to deploy
const chartVersion = "1.0.0";

// The name of your Helm release
const releaseName = "nginx-files-server";

// The Kubernetes namespace where this Helm chart will be deployed,
// this has to be existing namespace or you can set it up separately.
const namespace = "default";  // Replace with the proper namespace if necessary

// Deploy the nginx-files-server Helm chart
const nginxFilesServerChart = new k8s.helm.v3.Chart(releaseName, {
    chart: "nginx-files-server",
    version: chartVersion,
    fetchOpts: {
        repo: chartRepo,
    },  
    namespace: namespace,
});

// Export the base URL for the nginx-files-server deployment
export const nginxBaseUrl = nginxFilesServerChart.getResourceProperty("v1/Service", `${namespace}/${releaseName}-nginx-files-server`, "status").apply(status => status.loadBalancer.ingress[0].hostname);

```

In this program:

- We import the `@pulumi/kubernetes` package to interact with Kubernetes resources.
- We define variables such as `chartRepo`, `chartVersion`, `releaseName`, and `namespace` to configure our Helm release.
- We create an instance of `Chart` with the `nginx-files-server` as the chart name and other configurations like the repository URL and namespace.
- We export `nginxBaseUrl`, assuming your service will be exposed with a LoadBalancer and you need its hostname. If your setup is different, you might need to modify this part.

Make sure to replace the `chartRepo` with the actual URL where the `nginx-files-server` chart is hosted and set the `chartVersion` to the version number you want to deploy. The `namespace` field should be set to the namespace you wish to deploy the Helm chart to, ensuring it exists.

Remember to run `pulumi up` to initiate the deployment. The exported `nginxBaseUrl` will give you the hostname where you can access the Nginx file server once the deployment is complete and the service is up and running.

Please note that if you need specific configurations for your `nginx-files-server` instance, you would include a `values` property with the appropriate settings within the `Chart` resource declaration.
