Deploy the illumidesk helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the IllumiDesk Helm chart on OpenShift using Pulumi, you would typically perform the following steps:

1. Ensure you have an OpenShift cluster up and running.
2. Configure your Pulumi environment to interact with your Kubernetes cluster.
3. Write a Pulumi program that uses the Helm chart to deploy IllumiDesk to your cluster.

Before we dive into the code, let's explain the resources that will be used in the Pulumi program:

- `kubernetes.helm.v3.Chart`: This Pulumi Kubernetes resource allows you to deploy a Helm chart to a Kubernetes cluster. Helm charts are collections of pre-configured Kubernetes resources that are managed as a single unit, simplifying the deployment and management of applications on Kubernetes.

Assuming you have Pulumi installed and configured, along with kubectl access to your OpenShift cluster, the Pulumi program written in TypeScript will look something like this:

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

// Provide the Helm chart repository URL where IllumiDesk chart is stored.
const illumideskHelmChartRepo = 'https://charts.illumidesk.com/';

// Create a Kubernetes provider instance that uses your OpenShift context.
// This may already be correctly configured if your `kubectl` is set up to point to your OpenShift cluster.
const provider = new k8s.Provider('openshift-provider', {
    kubeconfig: 'your-kubeconfig', // Ensure you replace this with the actual kubeconfig data or path to your kubeconfig file.
});

// Deploy the illumidesk Helm chart using the kubernetes.helm.v3.Chart resource.
const illumideskChart = new k8s.helm.v3.Chart('illumidesk-chart', {
    chart: 'illumidesk',
    version: 'x.y.z', // Replace with the specific version of the IllumiDesk Helm chart you wish to deploy.
    fetchOpts: {
        repo: illumideskHelmChartRepo,
    },
    // You can define any custom values you want to override in the Helm chart here.
    // Refer to the IllumiDesk Helm chart's `values.yaml` file for what can be overridden.
    values: {
        // Example of custom values. The actual values will depend on IllumiDesk's chart.
        // replicaCount: 3,
        // service: {
        //     type: 'LoadBalancer',
        // },
    },
}, { provider });

// Export the web service endpoint for the deployed IllumiDesk instance
export const illumideskEndpoint = illumideskChart.getResourceProperty('v1/Service', 'illumidesk-chart', 'status').apply(status => {
    return status.loadBalancer.ingress[0].hostname;
});

```

Make sure you replace `'your-kubeconfig'` with your actual kubeconfig data or a path to your kubeconfig file. Replace `'x.y.z'` with the specific version of the IllumiDesk Helm chart if needed.

In this program, we declared a Helm chart resource, which Pulumi will use to communicate with your OpenShift cluster and create the necessary Kubernetes resources defined by the IllumiDesk Helm chart.

Additionally, we exported an `illumideskEndpoint` variable, which will display the endpoint of the IllumiDesk web service after the deployment is complete.

If you need to configure additional Helm values specific to IllumiDesk, ensure you provide the correct structure within the `values` object, according to the Helm chart's `values.yaml` file.

To run this Pulumi program:

1. Save the code to a file with a `.ts` extension, e.g., `deployIllumiDesk.ts`.
2. Run `pulumi up` in the same directory as your file to start the deployment process.
3. Pulumi will show you a preview of the resources to be created and ask for your confirmation before proceeding.
4. Once confirmed, the resources defined in the Pulumi program will be provisioned in your OpenShift cluster.
   
After the deployment is successful, you can access the `illumideskEndpoint` to interact with your IllumiDesk service.

This should get you started with deploying the IllumiDesk Helm chart to an OpenShift cluster using Pulumi. Remember, when working with actual deployments, you may need to adjust configurations and resource properties to fit your specific requirements and environment.
