Deploy the ibm-connect-direct helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Kubernetes cluster with Pulumi, you need to have a configured Kubernetes cluster and Helm installed. We'll assume that you have a cluster up and running and are authenticated to use `kubectl` with appropriate permissions.

Pulumi interacts with your Kubernetes cluster configuration via the `kubeconfig` file in your environment, which is typically located at `~/.kube/config`. If your `kubeconfig` file is in a non-standard location, you will either need to move it or set the `KUBECONFIG` environment variable with the path to your cluster configuration.

The `@pulumi/kubernetes` package provides a `Chart` resource that represents a Helm chart. Using this resource, we can deploy a chart to the Kubernetes cluster.

Below is a Pulumi program in TypeScript that deploys the "ibm-connect-direct" Helm chart into your Kubernetes cluster. The chart's repository needs to be specified since "ibm-connect-direct" is not available in the stable chart repository.

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

// If your Helm chart is hosted in a Helm repository, you must first add the repository.
// For example, to use the Bitnami repo, you would add it using `helm repo add`.
// We'll pretend `ibm-helm-repo` is the name of the Helm repository holding `ibm-connect-direct`.

const ibmConnectDirectChart = new kubernetes.helm.v3.Chart("ibm-connect-direct", {
    chart: "ibm-connect-direct",
    // Replace the `repo` value with the actual Helm repository URL
    // You may require additional configuration specific to the IBM Connect Direct Helm chart,
    // such as specifying `values` or `fetchOpts`.
    repo: "ibm-helm-repo",
    // You can customize values in the Helm chart by providing a `values` object
    values: {
        // Example of setting values
        // replicaCount: 1,
    },
    // Define the target namespace or remove if you're deploying to the default namespace
    namespace: "my-namespace",
});

// Export the base URL for the deployed IBM Connect Direct (this might vary based on the chart's configuration)
export const baseUrl = ibmConnectDirectChart.getResourceProperty("v1/Service", "ibm-connect-direct", "status").apply(s => `http://${s.loadBalancer.ingress[0].hostname}/`);
```

In this code, the `new kubernetes.helm.v3.Chart` call is what tells Pulumi to deploy the specified chart. The `name` parameter is the unique name that describes this deployment. The `chart` itself represents the `ibm-connect-direct` Helm chart.

Please ensure that you replace `"ibm-helm-repo"` with the actual repository URL where the `ibm-connect-direct` chart is hosted. Often Helm charts come with custom configuration that you can specify in the `values` object.

The final export of `baseUrl` assumes that the Helm chart deploys a `Service` of type `LoadBalancer`, and is expecting that the service will provide a single public ingress point. Note that this exact path might vary and can depend on the specifics of the Helm chart and on your Kubernetes environment, particularly if you're working with an ingress controller or need to reference something other than a `LoadBalancer` type service.

Now, let me explain some of the steps you would usually follow to run this:

1. Ensure that you have the Pulumi CLI installed and configured.
2. Create a new directory for your project and change into it.
3. Run `pulumi new typescript` to create a new Pulumi project using TypeScript.
4. Replace the auto-generated `index.ts` file with the code above.
5. Install the necessary dependencies by running `npm install @pulumi/kubernetes`.
6. Run `pulumi up` to deploy your Helm chart to the cluster.

During `pulumi up`, you will get details about the deployment plan, and Pulumi will await confirmation before proceeding with the actual deployment. Once approved, the Helm chart will be deployed to the targeted Kubernetes cluster, and the resulting base URL will be exported.
