Deploy the ibm-datapower-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an OpenShift cluster involves several steps, including setting up the Kubernetes provider for OpenShift, and then using the Helm Chart resource to deploy the chart. OpenShift is a distribution of Kubernetes optimized for continuous application development and multi-tenant deployment.

Here's a step-by-step guide on how you would deploy the `ibm-datapower-operator` Helm chart on OpenShift using Pulumi with TypeScript:

### Prerequisites:

- Ensure you have access to an OpenShift cluster.
- Make sure you have Pulumi installed and configured for use with your OpenShift cluster.
- Install Node.js and npm, which are required for running the Pulumi TypeScript programs.

### Step 1: Setting up a Pulumi Project

First, you need to create a new Pulumi project. On your terminal, run the following commands:

```bash
mkdir ibm-datapower-operator-deployment
cd ibm-datapower-operator-deployment
pulumi new typescript
```

This will create a new Pulumi project and generate the necessary files for you to get started.

### Step 2: Define the OpenShift Provider

For this step, we'll ensure the Kubernetes provider used by Pulumi is properly set up to interact with the OpenShift cluster. This typically requires setting the KUBECONFIG environment variable or via the kubeconfig Pulumi configuration.

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

// Use an existing Kubeconfig or define your OpenShift cluster configuration
const openshiftProvider = new k8s.Provider("openshiftProvider", {
    kubeconfig: process.env.KUBECONFIG, // Ensure the KUBECONFIG environment variable is set
});
```
  
### Step 3: Deploying the Helm Chart

Next, you will define the Helm chart you want to deploy – in this case, `ibm-datapower-operator`. You'll use the `Chart` resource from Pulumi's Kubernetes provider to deploy this Helm chart into your OpenShift cluster.

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

// Deploy the ibm-datapower-operator Helm chart
const datapowerOperatorChart = new helm.v3.Chart("ibm-datapower-operator", {
    chart: "ibm-datapower-operator",
    // Ensure you have the correct repo added or specify the repo URL here
    repo: "IBM repo URL", // Replace with IBM Helm chart repository URL
    version: "chart version", // Replace with the specific chart version you want to deploy
    namespace: "target-namespace", // Specify the namespace where the operator will be deployed
}, { provider: openshiftProvider });
```

In this code snippet, you are deploying the `ibm-datapower-operator` Helm chart. Make sure to replace the `"IBM repo URL"` with the actual repository URL for the IBM Helm charts, and `"chart version"` with the specific version of the Helm chart that you want to use.

### Step 4: Exporting Deployment Details

After the chart is deployed, you might want to export specific details such as the namespace or other metadata associated with your deployment.

```typescript
// Export the namespace of the Helm chart
export const namespace = datapowerOperatorChart.namespace;

// Additional outputs can also be exported if required
```

### Step 5: Running Pulumi

To run the Pulumi program and apply your deployment, you'll need to use the Pulumi CLI. Run the following command in your terminal:

```bash
pulumi up
```

This will prompt you to confirm the deployment based on the plan Pulumi shows you. Once you accept, Pulumi will provision the resources as described in your program.

### Conclusion

This Pulumi program will deploy the `ibm-datapower-operator` Helm chart to your OpenShift cluster. It automatically handles the communication with the cluster using your kubeconfig file. If you make any changes to your Pulumi program, such as updating the chart version or changing configuration values, running `pulumi up` will apply the changes to your cluster.

Remember to review the Helm chart documentation and values.yaml file provided by IBM for all the configurable options available for the `ibm-datapower-operator`. You can provide custom values to the helm chart by specifying the `values` parameter in the `Chart` resource.
