Deploy the ibm-security-solutions-prod helm chart on Kubernetes

Question

Pulumi · Accepted Answer

Deploying a Helm chart on Kubernetes using Pulumi is a straightforward process that involves creating a Pulumi program to define your infrastructure as code. With Pulumi, you use familiar programming languages such as TypeScript to create, deploy, and manage infrastructure.

In this case, we'll deploy the `ibm-security-solutions-prod` Helm chart on a Kubernetes cluster. To achieve this, we will perform the following steps:

1. Set up a Pulumi project.
2. Import the necessary packages for Kubernetes and Helm.
3. Define the Kubernetes provider, pointing it to your cluster.
4. Define the Helm chart resource, specifying the chart name, and optionally the chart version, values overrides, and the namespace for deployment.
5. Perform the deployment using Pulumi CLI.

Make sure you have access to a running Kubernetes cluster and have your `kubeconfig` file configured for access. Ensure that Helm and Pulumi are installed on your local machine.

Below is the TypeScript program that will accomplish this:

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

// Create a Kubernetes provider instance using the current context from kubeconfig.
const provider = new k8s.Provider("provider", {
    kubeconfig: process.env.KUBECONFIG, // This uses the KUBECONFIG environment variable.
});

// Deploy the `ibm-security-solutions-prod` helm chart.
const ibmSecurityChart = new k8s.helm.v3.Chart("ibm-security-solutions-prod", {
    chart: "ibm-security-solutions-prod",
    // You can specify the chart version you want to deploy.
    // version: "x.y.z",
    // Specify the namespace where the chart will be installed.
    namespace: "default",
    // If you need to override values in the chart, you can specify them here:
    // values: {
    //   // Override values here, for example:
    //   // someValue: "someOverride"
    // },
}, { provider });

export const chartName = ibmSecurityChart.metadata.name;
```

To deploy the above code, follow these steps:

1. Initialize a new Pulumi project or use an existing one.
2. Create a new TypeScript file (e.g., `index.ts`) if it doesn't already exist.
3. Paste the code into the TypeScript file.
4. Replace the `chart` property with the correct Helm chart repository and name, if needed.
5. Adjust any values or configurations according to your deployment requirements.
6. From the terminal, run `pulumi up` to preview and deploy the changes.
7. Confirm the deployment when prompted, and Pulumi will perform the deployment.

This program will use Pulumi's Kubernetes provider to connect to your cluster and then use the Helm Chart resource to deploy the specified Helm chart.

You should see output similar to the following if the deployment is successful:

```
Updating (dev):

Type                              Name                                 Status
 +   pulumi:pulumi:Stack               helm-chart-on-k8s-dev                created
 +   └─ kubernetes:helm.sh/v3:Chart    ibm-security-solutions-prod          created

Outputs:
    chartName: "ibm-security-solutions-prod-abcdefghi"

Resources:
    + 2 created

Duration: 4m56s
```

The exported `chartName` will be the generated name of your deployed Helm chart. You can use this name to query the deployed resources within your Kubernetes cluster or reference it in other Pulumi programs.
