Deploy the pinot helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the Pinot Helm chart on Linode Kubernetes Engine (LKE), you will create a Pulumi program written in TypeScript. This program will use Pulumi's Kubernetes package to interact with the Kubernetes API and deploy Helm charts.

Firstly, ensure that you have the following prerequisites set up:

- A Linode account, with access to the LKE (Linode Kubernetes Engine).
- The `kubectl` command-line tool configured to communicate with your LKE cluster.
- Helm, the package manager for Kubernetes, installed on your machine.
- Pulumi CLI installed and logged in.
- A Pulumi project initialized, with the appropriate Linode credentials configured.

The program will consist of the following steps:

1. Import necessary Pulumi and Kubernetes packages.
2. Create a `helm.v3.Chart` resource that specifies the Pinot Helm chart and its settings.

As you follow the code comments, they will explain each part of the program. Here is the Pulumi program that will deploy the Pinot Helm chart on your LKE cluster:

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

// Define the settings for the Pinot Helm chart. 
// These should be modified based on your specific requirements and environment.
const pinotChartSettings = {
    chart: "pinot",
    version: "0.1.0", // Specify the version of the Helm chart you wish to deploy.
    fetchOpts:{
        repo: "https://helm.pinot.apache.org", // This is the Helm repository for Pinot.
    },
    // Include additional settings and custom values for the Pinot Helm chart as needed.
    // values: {},
};

// Create a new Helm chart resource for Apache Pinot, using the defined settings.
const pinotChart = new k8s.helm.v3.Chart("pinot", pinotChartSettings);

// Export the URL of the Linode Kubernetes Engine cluster
export const kubeconfig = pinotChart.getResourceProperty("v1/Service", "pinot", "status").apply(status => status.loadBalancer.ingress[0].ip);
```

Replace the `chart`, `version`, and `repo` fields with the appropriate values for the Pinot Helm chart you wish to deploy. You might also need to specify custom values by modifying the `values` field accordingly.

Once this program is set up, you can deploy it using the Pulumi command line by running `pulumi up`. Pulumi will reach out to your LKE cluster and apply the Helm chart, starting the deployment of the Apache Pinot service.

The export at the end of the program provides the IP address of the load balancer that exposes the Pinot service after deployment is complete. You can use this IP address to interact with your Pinot cluster.

Remember, before running the Pulumi program, make sure your Pulumi stack is correctly configured to interact with your LKE cluster.

There are more advanced configurations and options you can apply depending on your use case, such as setting up persistent storage, configuring resource limits, or customizing Pinot configurations. You can find these options in the official [Pinot Helm chart documentation](https://helm.pinot.apache.org/).
