Deploy the ibm-connect-direct helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `ibm-connect-direct` Helm chart on OpenShift using Pulumi, you'll need to make use of the `kubernetes` package, which is the Pulumi provider for Kubernetes resources. The provider allows you to manage Kubernetes resources in a declarative way using Pulumi's infrastructure as code approach. Specifically, you'll use the `Chart` class from the Helm module (`kubernetes.helm.v3`) to deploy applications packaged as Helm charts.

Below is a step-by-step guide on how the code is structured:

1. Import the required Pulumi and Kubernetes packages.
2. Create an instance of `kubernetes.helm.v3.Chart` which references your Helm chart. You will need to specify the name of the chart, the repository where it's located, and any configuration options that are specific to this chart.
3. Deploy the chart onto your target OpenShift cluster. This step assumes you have already set up the necessary Kubernetes context to communicate with your OpenShift cluster.

Here's the Pulumi program in TypeScript that demonstrates these steps:

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

// Helm Chart information
const chartName = "ibm-connect-direct";
const chartVersion = "1.2.3"; // Specify the chart version you want to deploy
const chartRepo = "https://charts.example.com/"; // Replace with your Helm chart's repository URL
const namespace = "default"; // Specify the namespace where you want to deploy the chart

// Deploy ibm-connect-direct Helm chart
const ibmConnectDirectChart = new k8s.helm.v3.Chart("ibm-connect-direct", {
    chart: chartName,
    version: chartVersion,
    namespace: namespace,
    fetchOpts: {
        repo: chartRepo,
    },
    // If your ibm-connect-direct requires specific values, modify the 'values' field accordingly
    values: {
        // Example configuration - replace with your actual values
        key1: "value1",
        key2: "value2",
        // ...additional chart values
    },
});

// Export the URL for the ibm-connect-direct service
export const ibmConnectDirectUrl = ibmConnectDirectChart.getResourceProperty(
    "v1/Service", "ibm-connect-direct", "status"
).apply(status => status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip);
```

To use this code:

- Replace the `chartVersion`, `chartRepo`, and values in the `values` object with those relevant to the `ibm-connect-direct` Helm chart you want to deploy.
- Ensure you have access to your OpenShift cluster by configuring your local Kubernetes config file (`~/.kube/config`) with the necessary context.
- Finally, run `pulumi up` to deploy the chart.

Here's what each section of the code does:

- The `import` statement pulls in the required libraries from Pulumi's JavaScript/TypeScript SDK, namely the Kubernetes package.
- The `chartName`, `chartVersion`, `chartRepo`, and `namespace` constants hold the configuration that will tell Pulumi which Helm chart to deploy and where to find it.

The `ibmConnectDirectChart` is an instance of the `Chart` class. In the constructor:
  - `chart`: Specifies the name of the chart to be deployed.
  - `version`: Defines the version of the chart you wish to deploy.
  - `namespace`: Indicates the Kubernetes namespace into which the chart should be deployed.
  - `fetchOpts.repo`: Tells Pulumi where to fetch the chart from.
  - `values`: Provides any custom configuration needed for the chart.

The export statement at the end of the program will output the URL that you can use to access the deployed service, based on the ingresses/statuses reported by the resources created by the Helm chart.

Run this TypeScript program with Pulumi to deploy ibm-connect-direct on your OpenShift cluster. Make sure that you have Pulumi installed, and you're logged in to the Pulumi service (or using a local backend if you prefer), and have access to the target Kubernetes cluster where you want to deploy the Helm chart.
