Deploy the ibm-process-mining-instance helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `ibm-process-mining-instance` Helm chart on a Kubernetes cluster using Pulumi, you could use the `kubernetes.helm.v3.Chart` resource from the `@pulumi/kubernetes` package. This resource enables the deployment of Helm charts in a Kubernetes cluster.

First, ensure you have a Kubernetes cluster available and configured with `kubectl`. Pulumi relies on the kubeconfig file to interact with your cluster, so any cluster that you can access with `kubectl` can be used by Pulumi too.

The following program shows how to use Pulumi to deploy a Helm chart to a Kubernetes cluster. In this example, the Helm chart for `ibm-process-mining-instance` is fetched from a Helm repository, and we assume that the repository is already added to your Helm configuration and is named `ibm`. If that's not the case, you'll need to add the repository via Helm CLI or adjust the program to provide the chart's repository URL.

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

// Deploy the ibm-process-mining-instance Helm chart
const ibmProcessMiningInstanceChart = new kubernetes.helm.v3.Chart("ibm-process-mining-instance", {
    chart: "ibm-process-mining-instance",
    version: "1.0.0", // Specify the chart version you want to deploy
    fetchOpts: {
        repo: "https://charts.example.com/ibm", // Replace with the actual Helm repo URL
    },
    // Provide values to configure the chart as per your requirements.
    // This is just an example; consult the chart's documentation for valid values.
    values: {
        service: {
            type: "ClusterIP",
        },
        replicaCount: 1,
    },
});

// Export the resources' name
export const chartName = ibmProcessMiningInstanceChart.metadata.name;
```

**Explanation:**

1. **Imports**: The Pulumi Kubernetes package is imported, which provides the necessary resources to interact with Kubernetes.

2. **Chart Deployment**: The `Chart` resource is instantiated to deploy the `ibm-process-mining-instance` chart. The `chart` property specifies the name of the Helm chart, and `version` specifies the version of the chart to deploy.

3. **fetchOpts**: The `repo` option within `fetchOpts` is where you specify the Helm repository URL. Replace `https://charts.example.com/ibm` with the URL of the repository that hosts the `ibm-process-mining-instance` chart.

4. **Values**: The `values` field is a map where you can provide the values to customize the Helm chart installation. You should fill in this object with configuration settings according to the specifics of the IBM Process Mining chart you want to deploy.

5. **Export**: The program exports the name of the deployed Helm chart, which can be useful if you need to reference the chart elsewhere in your infrastructure.

Make sure to read the chart's documentation to know what values it expects and adjust the `values` property accordingly.

To run this Pulumi program, save it to a file, say `index.ts`, in a new directory and run the following commands within that directory:

```bash
# Install the Pulumi CLI if you haven't already
$ curl -fsSL https://get.pulumi.com | sh

# Install the Pulumi Kubernetes package
$ npm install @pulumi/kubernetes

# Log in to the Pulumi service or use the local mode
$ pulumi login

# Create a new Pulumi stack, which is an isolated environment for this instance
$ pulumi stack init dev

# Preview the deployment
$ pulumi up --yes
```

The above commands will set up Pulumi, install necessary dependencies, and finally, preview and perform the deployment.

Please replace the placeholder values with the actual data specific to your circumstance where necessary, for example, the Helm chart version and the repository URL.
