Deploy the onos-progran helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `onos-progran` Helm chart on a Kubernetes cluster using Pulumi, you'll need to follow these steps:

1. Ensure you have access to a Kubernetes cluster and that your `kubectl` is configured correctly to interact with it.
2. Install Pulumi and set up your Pulumi project.
3. In your Pulumi project, you will use the `@pulumi/kubernetes` package that allows you to interact with Kubernetes resources, including deploying Helm charts.

Below you will find a TypeScript program that uses Pulumi to deploy the `onos-progran` Helm chart. This program assumes that you have already set up a Pulumi project. If you haven’t done so, you can create a new project by running `pulumi new kubernetes-typescript`.

Here is the full Pulumi TypeScript program to deploy the `onos-progran` Helm chart:

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

// Create a Helm chart component resource that deploys onos-progran.
// `resource name` is the logical name for the resource in Pulumi, 
// while `chart name` is used by Helm during deployment to Kubernetes.
const progranChart = new k8s.helm.v3.Chart("onos-progran-chart", {
    repo: "your-helm-chart-repository",  // Replace with the name of the repository where onos-progran is hosted
    chart: "onos-progran",               // The name of the chart in the repository
    version: "chart-version",            // Replace with the target version of onos-progran Helm chart
    // You can override chart values here, for example:
    values: {
        // Specify any custom values your chart requires here
        // service: {
        //     type: "LoadBalancer",
        // },
    },
});

// Optional: Export resources created by the Helm chart 
// which might be needed for further operations or outputs.
export const progranService = progranChart.getResourceProperty(
    "v1/Service", "onos-progran-chart", "metadata"
);
```

In this program:
- We import the necessary Kubernetes package to work with Kubernetes resources.
- We create a Helm chart resource with `new k8s.helm.v3.Chart` and provide a name to the chart. This is the name Pulumi uses to track the resource in your infrastructure.
- We specify the repository where the `onos-progran` chart is located, its name, and the target version. Make sure to replace `"your-helm-chart-repository"` and `"chart-version"` with actual values specific to the `onos-progran` chart.
- You can also provide an optional `values` object that overrides the default values of the Helm chart. These values would typically be set in a values.yaml file when using Helm directly, but with Pulumi, they can be set directly in the code.

Once you have this code in your Pulumi project, you run `pulumi up` to execute the program and deploy the Helm chart.

Remember, this will not install Helm itself, it simply uses the Helm Chart to deploy `onos-progran` to Kubernetes. It assumes that you have already installed Pulumi CLI, logged into an account, and configured your Kubernetes cluster context correctly.

Be sure to replace any placeholders, such as `your-helm-chart-repository` and `chart-version`, with the actual values for the ONOS Progran Helm chart. If you're unsure about these details, you may need to refer to the documentation or repository that hosts the ONOS Progran Helm chart for correct configuration parameters.
