Deploy the ibm-mq-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the IBM MQ Operator Helm chart on an OpenShift cluster, we will follow these steps:

1. **Assuming**: You have an OpenShift cluster up and running and have the necessary permissions to deploy Helm charts to it.

2. **Connectivity**: Ensure that `kubectl` or `oc` CLI is configured correctly to interact with your OpenShift cluster.

3. **Helm**: Helm must be installed on your machine, and the Helm CLI must be available for Pulumi’s Helm support to work.

In this program, we'll utilize Pulumi's `kubernetes.helm.v3.Chart` resource, which allows you to deploy a Helm chart to a Kubernetes cluster. The IBM MQ Operator chart will be deployed into the OpenShift cluster.

The `Chart` resource takes several arguments:

- `chart`: Specifies the name of the chart to be deployed.
- `values`: Provides configuration values that override the default settings in the Helm chart.
- `namespace`: Defines the namespace in which to deploy the chart. If the namespace doesn’t exist, it will be created by Helm.
- `fetchOps`: Pass options for fetching Helm charts from remote repositories.
  
Here is a TypeScript program that deploys the IBM MQ Operator Helm chart:

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

// Create an instance of the kubernetes Provider connected to your OpenShift cluster.
const openshiftProvider = new kubernetes.Provider("openshiftK8s", {
    // `kubeconfig` can be set explicitly or Pulumi will use the default kubeconfig location.
    // kubeconfig: your-kubeconfig,
});

// Define the IBM MQ Operator Helm chart deployment.
const ibmMqOperatorChart = new kubernetes.helm.v3.Chart("ibm-mq-operator", {
    // Add the IBM Helm chart repository and specify the IBM MQ Operator chart name.
    chart: "ibm-mq-operator",
    version: "x.y.z", // Replace with the specific chart version you want to deploy
    namespace: "mq-operator-namespace",  // Ensure this namespace exists in your OpenShift cluster.
    fetchOpts: {
        repo: "https://ibm.github.io/ibm-mq-helm", // This URL is hypothetical; you will need the actual repository URL for the IBM MQ Operator.
    },
}, { provider: openshiftProvider });

// Export the chart name and namespace as outputs.
export const chartName = ibmMqOperatorChart.metadata.name;
export const chartNamespace = ibmMqOperatorChart.metadata.namespace;
```

This program does the following:
- Imports the necessary Pulumi and Kubernetes libraries.
- Sets up a Kubernetes provider pointing to your OpenShift cluster.
- Defines the deployment of the IBM MQ Operator Helm chart using the Chart resource.

You will need to replace `x.y.z` with the actual version of the Helm chart you wish to deploy. Also, ensure that the namespace provided exists or that you have the appropriate permissions to create namespaces if it does not.

To run this Pulumi program:

1. Save the code to a file with a `.ts` extension, for example, `deployIbmMqOperator.ts`.

2. Run `npm install` to install the necessary dependencies.

```bash
npm install @pulumi/kubernetes
```

3. Execute the Pulumi program with the appropriate Pulumi CLI commands.

```bash
pulumi up
```

This command will prompt you to confirm the deployment after showing you a preview of the resources that will be created.

After running the program, the IBM MQ Operator Helm Chart will be deployed to your OpenShift cluster, and you can manage IBM MQ instances within that cluster using the operator.
