Deploy the kube-plex helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the kube-plex Helm chart on an OpenShift cluster, you'll need to have an OpenShift cluster up and running and have Helm installed. The Pulumi program below uses the `kubernetes.helm.v3.Chart` resource to deploy a Helm chart within your OpenShift cluster.

This Pulumi program assumes you have configured your Pulumi Kubernetes provider to point to your OpenShift cluster. Helm charts can be deployed using a variety of customizable options, but this program will demonstrate a very basic deployment with default settings.

Here's the TypeScript program to deploy the kube-plex Helm chart on OpenShift:

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

// Create an instance of the kube-plex Helm chart
const kubePlexChart = new k8s.helm.v3.Chart("kube-plex", {
    // Assuming 'kube-plex' is available in the default Helm repo, otherwise specify 'repo' option.
    chart: "kube-plex",
    // Specify the OpenShift namespace where the chart should be installed.
    namespace: "plex-namespace", // Replace with the actual namespace
    // Include any custom values here, or omit the 'values' key to use the defaults.
    values: {
        // Custom values for the Helm chart can be set here. This is an example:
        // persistence: {
        //     enabled: true,
        //     storageClass: "my-storage-class", // Replace with your storage class
        // },
    },
    // Additional options can be set here such as 'version' for a specific chart version.
});

// Export any important information, e.g., the service endpoint
export const kubePlexServiceEndpoint = kubePlexChart.getResourceProperty(
    "v1/Service", // Adjust kind and apiVersion as necessary
    "kube-plex",  // Adjust based on real service name (found in chart's service.yaml or release info)
    "status"
).apply(status => status.loadBalancer.ingress[0].ip);
```

Explanation of the program:

1. The `@pulumi/kubernetes` package is imported to interact with Kubernetes resources.
2. The `kubernetes.helm.v3.Chart` resource is instantiated to deploy the kube-plex Helm chart. The constructor requires a name for the resource instance and a configuration object that describes the Helm chart deployment. 
3. The `chart` property specifies the name of the chart to deploy. Replace `"kube-plex"` with the exact chart name if different.
4. The `namespace` property is where you'll specify which OpenShift project (namespace) the chart should be deployed into. Replace with your target namespace.
5. The `values` property is an object that you can use to override default chart values. This is where you can provide custom configuration for your kube-plex deployment.
6. The `version` option (if needed) allows you to specify a particular version of the chart to deploy.
7. After the deployment, an export statement is used to output the service endpoint of the deployed kube-plex. The `getResourceProperty` function is used to get a specific property from a resource created by the Helm chart. Here, we are trying to extract the IP address from the load balancer's ingress. Note that you will need to adjust the kind (`v1/Service`), resource name (`kube-plex`), and the properties to match those defined by your Helm chart.

Please note that you may need to set up the Helm repository that contains the kube-plex chart before running this if it's not part of the stable repositories known by Helm.

To run this Pulumi program, save it as `index.ts`, install dependencies with `npm` or `yarn`, and run `pulumi up`. Make sure that you have authenticated with your OpenShift cluster and that your Pulumi stack is correctly configured to use your OpenShift Kubernetes context.

Please replace placeholders such as `plex-namespace` with the actual namespaces and adjust the `values` according to the kube-plex Helm chart's documentation and your specific requirements.
