Deploy the ibm-sccm helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying an IBM SCCM (Software Configuration and Change Management) Helm chart on Kubernetes can be achieved with Pulumi through the use of the `kubernetes.helm.v3.Chart` resource. This functionality provided by Pulumi allows you to deploy any Helm chart into a Kubernetes cluster, making Helm's catalog of applications available for easy deployment.

Below, you’ll find a Pulumi program written in TypeScript that deploys the ibm-sccm Helm chart to an existing Kubernetes cluster. The program assumes that you have already set up Pulumi with access to the desired Kubernetes cluster, and that `kubectl` configured to connect to the same Kubernetes cluster.

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

// Define the settings for the IBM SCCM Helm chart
const chartName = "ibm-sccm";
const chartRepo = "https://raw.githubusercontent.com/IBM/charts/master/repo/stable";
const chartVersion = "YOUR_CHART_VERSION"; // Replace with the specific chart version you want to use
const releaseName = "my-ibm-sccm-release";
const namespace = "ibm-sccm-namespace";

// Create a namespace for the IBM SCCM Helm chart if it doesn't already exist
const ns = new k8s.core.v1.Namespace(namespace, {
    metadata: {
        name: namespace,
    },
});

// Deploy the IBM SCCM Helm chart
const ibmSccmChart = new k8s.helm.v3.Chart(releaseName, {
    chart: chartName,
    version: chartVersion,
    namespace: namespace,
    fetchOpts: {
        repo: chartRepo,
    },
}, { dependsOn: [ns] });

export const ibmSccmChartStatus = ibmSccmChart.status;
```

Here is what each part of the script is doing:

- **Import the Kubernetes package**: The `@pulumi/kubernetes` package is imported to interact with Kubernetes resources.

- **Configuration**: Set up some constants at the beginning of the script, which specify the Helm chart details such as its name, repository URL, and version.

- **Namespace creation**: Before deploying the chart, a Kubernetes namespace is created. This allows for logical separation within the cluster, and the chart will be deployed within this namespace.

- **Helm chart deployment**: The `kubernetes.helm.v3.Chart` resource is then used to deploy the IBM SCCM Helm chart. You specify the details of the chart such as the repository URL and version. The `dependsOn` option is provided to ensure the namespace is created before the Helm chart is deployed.

- **Export**: Finally, the status of the Helm chart is exported. This allows you to get feedback about the deployment after running the Pulumi program.

Remember to replace `YOUR_CHART_VERSION` with the version number of the Helm chart that you want to deploy.

To execute this Pulumi program, you would:

1. Save the script to a file named `index.ts`.
2. Run `pulumi up` in the same directory as the file. Pulumi would perform the diffing, show you the planned changes, and prompt you for an approval before making those changes to your Kubernetes cluster.
