Deploy the sherlock helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Sherlock Helm chart on a Kubernetes cluster using Pulumi, you'll need to use the `kubernetes.helm.sh/v3.Chart` resource from the Pulumi Kubernetes provider. This resource allows you to deploy a Helm chart to a Kubernetes cluster.

Below is a program in TypeScript that demonstrates how to do this. The program assumes you have a Kubernetes cluster already and your `kubeconfig` file is set up correctly. Pulumi will use your `kubeconfig` file by default to communicate with your Kubernetes cluster.

Here's what the program does:
- It imports the necessary modules from Pulumi and the Pulumi Kubernetes provider.
- It creates a new Helm chart resource, specifying the name of the chart (`sherlock`), and optionally, you can provide the Helm repository details if the chart is not a part of the stable repository.
- It specifies the namespace to deploy the chart into, which could be `default` or a custom namespace that should already exist in your cluster.

Here's the Pulumi program:

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

// Create a new instance of the Chart resource specifying the Helm chart to deploy.
// Replace `chartRepoURL` with the appropriate URL for the Sherlock Helm chart repository
// and `version` with the chart version you wish to install.
const sherlockChart = new k8s.helm.sh.v3.Chart("sherlock", {
  chart: "sherlock",
  // Uncomment the next line if the chart repository is not the default one.
  // repo: "chartRepoURL",
  // Uncomment and specify the chart version you want to deploy
  // version: "chartVersion",
  namespace: "default", // Replace with the name of the namespace you would like to deploy into.
  // You can add additional customization by specifying values for the chart here:
  // values: {
  //   key: "value",
  // }
});

// Export the name of the chart
export const chartName = sherlockChart.name;
```

This basic program will deploy the Sherlock Helm chart with the default configuration. If you need to customize your Helm chart deployment (for example, setting custom values or specifying a different namespace), you can do so by providing additional parameters to the `Chart` resource.

Before running this program, make sure you have set up the Pulumi CLI and logged in to your Pulumi account. Install the Pulumi CLI according to the instructions on the [official Pulumi website](https://www.pulumi.com/docs/get-started/kubernetes/).

Once you have Pulumi set up, create a new Pulumi project with `pulumi new kubernetes-typescript`, and place the code inside the `index.ts` file. Then, run `pulumi up` to preview and deploy your changes.

Please note, the specific details for the `chartRepoURL` and the `chartVersion` would need to be determined based on the actual Helm chart you wish to deploy. The above code assumes that those details are available to you. If your Helm chart requires specific configurations (provided via Helm `values`), replace the commented-out `values` section with the necessary configurations.

Remember to check official Helm chart repositories or documentation to get the exact `chartRepoURL` and other specific values you might need to pass to `values` for the Sherlock Helm chart.
