Deploy the mozilla-common-voice helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Mozilla Common Voice Helm chart on OpenShift using Pulumi, you'll first need the Helm chart's repository URL and chart name. The Common Voice chart might be available on a Helm chart repository, or it could be packaged and hosted somewhere accessible to your OpenShift cluster.

Here is a step by step guide along with a Pulumi TypeScript program to help you with the deployment:

1. **Setting up the Pulumi Project**: Before writing the code, ensure you have a Pulumi project set up. If you don't have a project already, you can create one by running `pulumi new typescript`.

2. **OpenShift Configuration**: Make sure OpenShift is properly configured with the necessary credentials.

3. **Writing the Pulumi Program**:

- **Importing Dependencies**: We'll import the necessary Pulumi Kubernetes package to deploy resources to OpenShift.
    
    - **Creating a Kubernetes Provider**: When using Pulumi with a provider like OpenShift, we need to create a Kubernetes Provider instance, which will communicate with OpenShift's API endpoint. This requires you to configure the provider with the appropriate kubeconfig or context information.
    
    - **Deploying the Helm Chart**: Using Pulumi's `Chart` resource, we will then declare the deployment of the `mozilla-common-voice` chart. You will need to replace `CHART_REPO_URL` with the actual repository URL where the chart is hosted and `mozilla-common-voice` with the correct chart name if it's different.

Here is the Pulumi TypeScript code to deploy the Mozilla Common Voice Helm chart to your OpenShift cluster:

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

// Replace the `CHART_REPO_URL` with the actual repository URL and
// `mozilla-common-voice` with the actual chart name (if necessary).
const chartRepoUrl = "CHART_REPO_URL"; // Placeholder for chart repository URL
const chartName = "mozilla-common-voice"; // Placeholder for chart name

// Create a Kubernetes provider instance that targets our OpenShift cluster.
// We need to make sure that the OpenShift credentials are configured correctly
// in the environment or via the kubeconfig file.
const openshiftProvider = new k8s.Provider("openshiftProvider", {
  // Assuming the kubeconfig is set up in the environment or kubeconfig file
});

// Deploy the Mozilla Common Voice Helm chart using the Pulumi Kubernetes provider.
const commonVoiceApp = new k8s.helm.v3.Chart(chartName, {
  chart: chartName,
  version: "CHART_VERSION", // Specify the chart version here, if applicable
  fetchOpts: {
    repo: chartRepoUrl,
  },
  namespace: "mozilla-common-voice", // Specify the namespace to deploy to, this could be an existing one or a new one
}, { provider: openshiftProvider });

// The `commonVoiceApp` now contains all the Kubernetes resources defined by the Helm chart.
// Below is how you can export an output, for example, the URL to access the deployed application.
// Depending on the chart, you may need to adjust the way the URL is constructed.
export const applicationURL = commonVoiceApp.getResourceProperty("v1/Service", "mozilla-common-voice-svc", "status").apply(status => {
  // If the service is of Type LoadBalancer or has an ingress, fetch that data here to construct the URL.
  // You will need to check how the Common Voice Helm chart is exposing the service to set this part correctly.
});
```

This program creates an instance of the `Chart` from the Pulumi Kubernetes package, targeting your OpenShift cluster using a Kubernetes Provider.

To find the exact repository URL and chart name for Mozilla Common Voice, you would typically search Helm's public repositories or the project's official repositories. This information is necessary to fill in the `CHART_REPO_URL` and adjust the chart name if needed.

After you write the Pulumi code, you'd run `pulumi up` to deploy the chart to your OpenShift cluster. If there are services, ingresses, or other resources created by the Helm chart, you can add additional Pulumi code to export details about these resources, such as URLs or IP addresses.

**Note**: The `CHART_VERSION` and other placeholders should be replaced with actual values depending on the chart you are using. The `namespace` should also be an existing namespace on your OpenShift cluster or a new one that you want to create for this application.

Refer to the [Pulumi Kubernetes API documentation](https://www.pulumi.com/docs/reference/pkg/kubernetes/) for more details on the Kubernetes provider and Helm charts.
