Deploy the ibm-ssp-ps helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `ibm-ssp-ps` helm chart on a Kubernetes cluster using Pulumi, you will first need to ensure you have a Kubernetes cluster up and running. Pulumi can also help you create a Kubernetes cluster on various cloud providers, but for the sake of this tutorial, I will focus on deploying the chart to an existing Kubernetes cluster.

We'll be using the `kubernetes.helm.v3.Chart` resource from the `@pulumi/kubernetes` package to deploy the `ibm-ssp-ps` helm chart. This resource allows you to deploy Helm charts into a Kubernetes cluster. Helm helps you manage Kubernetes applications through Helm Charts, which are packages of pre-configured Kubernetes resources.

Here's a step-by-step explanation of the Pulumi program in TypeScript that accomplishes the deployment:

1. **Import Dependencies**: Import the necessary Pulumi and Kubernetes packages.
2. **Create a Helm Chart Resource**: Use the `kubernetes.helm.v3.Chart` class to create an instance representing the helm chart you want to deploy.
3. **Chart Settings**: Provide settings like the chart name, version, and any custom values you wish to override in the chart's default configuration.

Below is a commented TypeScript program that deploys the `ibm-ssp-ps` helm chart on a Kubernetes cluster:

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

// Define the settings for the `ibm-ssp-ps` helm chart.
const chartName = "ibm-ssp-ps";
const chartVersion = "x.x.x";  // Replace x.x.x with the actual chart version
const chartRepo = "https://charts.your-repository.com"; // Replace with the actual Helm repo URL that hosts the `ibm-ssp-ps` chart.

// Deploy the `ibm-ssp-ps` helm chart into the Kubernetes cluster.
const sspPsChart = new k8s.helm.v3.Chart(chartName, {
    repo: chartRepo,
    chart: chartName,
    version: chartVersion,
    // You can specify custom values according to the helm chart's documentation
    values: {
        // ...Your custom values here
    },
}, { provider: // ... Your Kubernetes provider or leave blank to use the default context from kubeconfig });

export const chart_resources = sspPsChart.resources;
```

To understand this program and use it:

1. **Install Node.js and npm**: Ensure you have Node.js and npm installed on your machine to work with Pulumi and TypeScript.
2. **Install Pulumi CLI**: Download and install the Pulumi CLI and set up your Pulumi account.
3. **Configure Kubernetes**: You need `kubectl` configured to connect to your Kubernetes cluster. Pulumi uses the kubeconfig file to interact with your cluster.
4. **Install Pulumi Packages**: Install the necessary Pulumi packages using npm by running `npm install @pulumi/kubernetes`.
5. **Replace Chart Details**: Make sure to replace `chartVersion` and `chartRepo` with the appropriate values for the `ibm-ssp-ps` helm chart.
6. **Add Custom Values**: Customize the `values` property if you want to override any of the default settings in the Helm chart.
7. **Initialize a Pulumi Project**: Create a new directory for your Pulumi project and run `pulumi new typescript` inside it to initialize a new TypeScript project.
8. **Add the Code**: Replace the contents of `index.ts` with the code provided above.
9. **Deploy**: Use the `pulumi up` command to deploy your chart to the cluster.

Remember to check the documentation for the `ibm-ssp-ps` helm chart to understand what values can be customized in the `values` object. After running `pulumi up`, Pulumi will show you a preview of the actions it will take and prompt for confirmation before making any changes to your cloud resources.
