Deploy the tt-workflow helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy a Helm chart on an OpenShift cluster using Pulumi, you would use the `kubernetes.helm.v3.Chart` resource. This resource is part of Pulumi's Kubernetes provider and allows you to deploy Helm charts in a Kubernetes cluster. OpenShift is a Kubernetes distribution, so the same resources can be used.

Below, you'll find a TypeScript program that demonstrates how you would use Pulumi to deploy the `tt-workflow` Helm chart to an OpenShift cluster. This program assumes you have already configured Pulumi to use your OpenShift cluster's kubeconfig file.

Here is a step-by-step guide to what the following Pulumi program does:

1. Import the necessary Pulumi and Kubernetes packages.
2. Instantiate a Helm chart using the Pulumi Kubernetes provider, specifying the necessary parameters, such as the Helm chart name (`tt-workflow`), repo URL, and any other configuration values for the chart.

Please note that you should replace placeholders such as `REPO_URL` with the actual URL of the Helm chart repository where `tt-workflow` is hosted, and configure the `values` field with any necessary customization required for the Helm chart deployment.

Here is the TypeScript program:

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

// Deploy a Helm chart 'tt-workflow' in the 'default' namespace
// The 'repo' will need to be specified with the URL where your Helm chart is located
const ttWorkflowChart = new k8s.helm.v3.Chart('tt-workflow', {
    chart: 'tt-workflow',
    version: '1.0.0', // Specify the chart version you want to deploy
    namespace: 'default', // You can specify the namespace where you want to deploy the chart
    fetchOpts: {
        repo: 'REPO_URL', // Replace with the actual Helm chart repository URL
    },
    // If your chart requires additional values, provide them in the 'values' field.
    values: {
        // Example configuration values
        // Replace these with actual configuration values required for 'tt-workflow' Helm chart
        key1: 'value1',
        key2: 'value2',
        // ...
    },
}, { provider: k8sProvider });

// Export the base URL for the deployment
// This is a placeholder to demonstrate how to export outputs from your deployment
export const base_url = ttWorkflowChart.getResourceProperty("v1/Service", "tt-workflow", "status").apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);
```

Please be careful to validate the `values` field with the correct values expected by the `tt-workflow` Helm chart. The exported `base_url` value is just a placeholder; you would replace it with the actual service or endpoint you wish to export from your deployment. Typically, you will find this detail in the Helm chart documentation or by inspecting the chart's resources.

After preparing your TypeScript code, you can deploy the Helm chart to your OpenShift cluster by running `pulumi up` in the Pulumi project directory where your code resides.
