Deploy the ibm-mq-operator helm chart on Digital Ocean Kubernetes Service

Question

Pulumi · Accepted Answer

To deploy the IBM MQ Operator Helm Chart on Digital Ocean Kubernetes Service using Pulumi, you'll first need to set up a Kubernetes cluster on Digital Ocean. Once your cluster is created, you'll then use the Helm Chart resource to deploy the IBM MQ Operator.

The steps we will follow are:

1. Create a Kubernetes cluster on Digital Ocean.
2. Deploy the IBM MQ Operator using a Helm Chart.

We'll utilize DigitalOcean's `KubernetesCluster` resource to create the cluster and use the `Chart` resource from the `kubernetes` package to deploy the IBM MQ Operator Chart.

Here's a detailed TypeScript program that uses Pulumi to perform these actions:

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

// Create a DigitalOcean Kubernetes cluster
const cluster = new digitalocean.KubernetesCluster("do-cluster", {
    region: "nyc1",
    version: "latest", // Make sure you use a supported version here. The string "latest" will use the latest available version.
    nodePool: {
        name: "default",
        size: "s-2vcpu-2gb", // This is the size of the droplet (DigitalOcean's term for a VM)
        nodeCount: 2, // The number of droplets to create
    },
});

// Using the kubeconfig from the generated DigitalOcean cluster to create a provider
const provider = new k8s.Provider("do-k8s", {
    kubeconfig: cluster.kubeConfigs[0].rawConfig,
});

// Deploying the IBM MQ Operator Helm chart
const ibmMqOperatorChart = new k8s.helm.v3.Chart("ibm-mq-operator", {
    chart: "ibm-mq-operator",
    version: "1.0.0", // Specify the version of the chart you want to deploy
    fetchOpts: {
        repo: "https://raw.githubusercontent.com/IBM/charts/master/repo/stable/", // URL of the Helm repository where the chart is located
    },
}, { provider });

// Export the cluster's kubeconfig and the IBM MQ Operator Helm release status
export const kubeconfig = cluster.kubeConfigs[0].rawConfig;
export const ibmMqOperatorStatus = ibmMqOperatorChart.status;
```

In this program, we create a Kubernetes cluster on Digital Ocean by specifying the desired region, version, and size of the node pool. Note that we only create a single node pool with two droplets (VMs), which minimizes costs but isn't necessarily suited for production workloads.

After creating the cluster, we establish a Pulumi Kubernetes provider that uses the kubeconfig from the newly created cluster. This allows Pulumi to interact with your cluster.

We then declare a Helm chart resource for the IBM MQ Operator. We specify the name and version of the chart and provide the repository URL where the chart can be found. This code assumes there is a Helm chart named `ibm-mq-operator` in the IBM Helm chart repository at version `1.0.0`.

Lastly, we export the kubeconfig for the cluster and the status of the Helm release. The kubeconfig allows you to manage your Kubernetes cluster with tools such as `kubectl`, and the Helm release status can provide information about the deployment of the IBM MQ Operator.

Remember to install the required Pulumi packages using npm before running this program:

```shell
npm install @pulumi/pulumi @pulumi/digitalocean @pulumi/kubernetes
```

Run the program with the Pulumi CLI to provision your resources:

```shell
pulumi up
```

This command will prompt you to confirm the deployment after showing you a preview. Once approved, Pulumi will provision the Digital Ocean Kubernetes Service cluster and deploy the IBM MQ Operator Helm chart to it.
