Deploy the konvoyconfig helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart on Kubernetes using Pulumi, you'll first need to ensure you have a Kubernetes cluster set up and that `kubectl` is configured to communicate with it, as Pulumi uses the current context from the kubeconfig file. When deploying applications via Helm, Pulumi leverages the Kubernetes provider and the `helm.v3.Chart` resource to wrap the Helm functionality.

Below, I'm going to guide you through the process of deploying a Helm chart named "konvoyconfig" on Kubernetes using Pulumi and TypeScript. This example assumes that the "konvoyconfig" chart is publicly available in a Helm repository or that you have the necessary information to add a private repository.

Firstly, ensure that you have installed the Pulumi CLI and configured it with the appropriate cloud provider credentials.

Now, I'll walk you through a Pulumi program that performs the following steps:
1. Sets up the Pulumi Kubernetes provider to interact with your cluster.
2. Deploys the "konvoyconfig" Helm chart to your Kubernetes cluster.

Here's the TypeScript program:

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

// You can specify the settings for your Helm release below.
const chartName = "konvoyconfig";
const chartVersion = "1.0.0"; // Replace with the actual version of the chart.
const releaseName = "my-konvoyconfig";
const namespace = "default"; // Ensure this namespace exists in your cluster.

// Define the Helm chart.
const konvoyconfigChart = new k8s.helm.v3.Chart(releaseName, {
    chart: chartName,
    version: chartVersion,
    namespace: namespace,
    // Uncomment and edit the below if your chart requires custom values or you have a private Helm repo.
    // values: {
    //     key: "value", // Custom values to override the chart's default configuration.
    // },
    // fetchOpts: {
    //     repo: "http://your-helm-chart-repo.com/", // URL for the Helm repository that holds the chart.
    // },
}, {
    provider: k8sProvider, // If you have a specific provider instance, pass it here.
});

// Export the resources' details if needed.
export const chartStatus = konvoyconfigChart.status;
```

This program will deploy the "konvoyconfig" Helm chart with the given version to the specified namespace. Replace the `chartVersion` with the version of the konvoyconfig chart you wish to deploy. The `values` field is where you can provide custom configuration values for the chart, and the `fetchOpts` provide the details of the Helm repository.

Before running this program, make sure you install the Pulumi Kubernetes package:

```bash
npm install @pulumi/kubernetes
```

Then you can run the program with the Pulumi CLI:

```bash
pulumi up
```

This command starts the deployment process. Pulumi will present you with a summary of the planned changes, which you can confirm to proceed with the deployment. After it successfully completes, the specified version of the "konvoyconfig" chart will be deployed to your Kubernetes cluster in the designated namespace.
