Deploy the keeper helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Kubernetes using Pulumi, you can use the `kubernetes.helm.v3.Chart` resource. This resource allows you to install, configure, and manage Helm charts in a Kubernetes cluster.

We'll create a Pulumi program in TypeScript that deploys the `keeper` Helm chart to a Kubernetes cluster. You will need to have Helm and Pulumi installed on your machine, along with `kubectl` configured for the Kubernetes cluster you wish to deploy to.

Below is a detailed explanation followed by the TypeScript program that accomplishes this task:

1. **Import necessary modules**: We import the required modules from Pulumi and define any necessary configuration settings or constants.

2. **Create a Helm Chart resource**: Utilizing the `Chart` resource from the `@pulumi/kubernetes/helm` package to define the Helm chart we want to deploy. You will need to specify the chart name and optionally, the repository URL, if the chart is not found in the default Helm repositories.

3. **Export any required outputs**: After the chart is deployed, we can export certain outputs such as the status, which might include URLs, external IP addresses, or other data depending on what the Helm chart provides.

Here's the Pulumi program in TypeScript for deploying the `keeper` Helm chart:

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

// You must have a Kubernetes cluster and Pulumi configured to deploy to that cluster.
// Define the name and repository URL for the Keeper Helm chart.
const chartName = "keeper";
const chartRepo = "https://charts.example.com/"; // Replace with the actual repository URL for the keeper chart

// Deploy the Helm chart for Keeper to the Kubernetes cluster.
const keeperChart = new k8s.helm.v3.Chart(chartName, {
    repo: chartRepo,
    chart: chartName,
    // If you have specific values you wish to override in the Helm chart, specify that here.
    // `values` is an object where keys are the setting names within the chart's 'values.yaml' file.
    values: {
        // Example of overriding a value, adjust according to the actual values you might want to change:
        // image: {
        //     repository: "keeper/keeper",
        //     tag: "latest"
        // },
        // service: {
        //     type: "LoadBalancer"
        // },
    },
    // Specify the namespace where the chart should be deployed if you have a preference.
    // If not specified, it will be deployed in the 'default' namespace.
    namespace: "default",
});

// Export the status or other properties of the Helm chart, which could include the deployed services' URLs.
// This depends on what resources the Helm chart creates and what data it outputs.
export const chartStatus = keeperChart.status;

```

This program will deploy the `keeper` chart from the specified Helm repository into your Kubernetes cluster. Keep in mind that values and other configurations such as chart `version`, `namespace`, or `values` should be customized to match the requirements of the `keeper` chart you are deploying.

Before running this Pulumi program, you should ensure your Pulumi CLI is configured for your Kubernetes cluster. You can then run `pulumi up` to start the deployment process.

Remember, the success of this operation depends on the correctness of the chart name and repository URL, as well as any specific configurations required by the `keeper` Helm chart. Be sure to check the chart's documentation for the right configuration to use.
