Deploy the jira-service-desk-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the `jira-service-desk-operator` Helm chart on an OpenShift cluster using Pulumi, you need to use the Kubernetes provider to interact with the cluster and Helm charts. The Kubernetes provider allows you to manage Kubernetes resources including Helm charts, which are packages of pre-configured Kubernetes resources.

Here's how you can do this with Pulumi and TypeScript:

1. You'll need to have access to an OpenShift cluster.
2. Verify that Helm CLI is installed on your machine, as Pulumi will use it to deploy the Helm chart.
3. Ensure that `kubectl` is configured to connect to your OpenShift cluster.
4. The name `jira-service-desk-operator` suggests that it's a custom Helm chart, so you might need to add a repository that contains this chart before you begin, or reference it by its file path if it's stored locally.

Below is a Pulumi program that demonstrates how to deploy a Helm chart to an OpenShift cluster:

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

// Assuming you have the OpenShift cluster already configured in your `kubectl` context,
// Pulumi will use that context to deploy resources.

// Create a new instance of the `Chart` resource, which represents the Helm chart.
const jiraServiceDeskChart = new k8s.helm.v3.Chart("jira-service-desk-operator", {
    // Specify the chart name and version you wish to deploy. 
    // If the chart is in a custom repository or a local path, you need to configure `repo` or `path` respectively.
    chart: "jira-service-desk-operator",
    version: "x.y.z", // Replace with the actual chart version
    // Uncomment the following line and specify the repo if it's from a custom Helm repository
    // repo: "https://example.com/helm-charts",
    namespace: "default", // Replace with the target namespace on OpenShift where you want to deploy the chart

// If the Helm chart requires any custom values, define them here.
    values: {
        // ... set any custom values here
    },

// If authentication is required to access the OpenShift cluster, specify the `transformations` field.
    // This allows you to modify the resources generated by Helm before they get applied to the cluster.
    transformations: [
        (obj: any) => {
            // For example, you might need to add specific annotations or labels to the deployed resources
            // or manipulate the service account the operator will use.
            // Here is the place to do that kind of transformations if needed.
        },
    ],
}, { provider: /* If needed, additional provider configuration can go here */ });

// After running `pulumi up`, Pulumi will deploy the Helm chart to your OpenShift cluster.

// Export the status URL so that you can easily access it after deployment
export const statusUrl = jiraServiceDeskChart.getResourceProperty(
    "v1/Service", // Replace with the kind of resource you expect to output a URL
    "jira-service-desk-service", // Replace with the name of the service deployed by the Helm chart
    "status.loadBalancer.ingress[0].hostname" // Replace with the exact field path for the URL
);
```

This program does the following:

- It imports the necessary Kubernetes package from Pulumi to manage resources within a Kubernetes cluster.
- It creates a new Helm chart instance which Pulumi will use to deploy the `jira-service-desk-operator` chart into the specified namespace on your OpenShift cluster.
- The `values` field in the `Chart` resource is where you can specify any configuration options that the Helm chart accepts. Replace the comments with actual values required for the Jira Service Desk Operator.
- The `transformations` field (commented out in the example) can be used to modify the resources defined by the Helm chart before they are created on the cluster. This is useful for cases where you may need to apply custom metadata or tweak resource definitions.

Remember to replace `"x.y.z"` with the actual version of the `jira-service-desk-operator` chart, and also configure the proper repository if it's not a standard Helm chart available on Helm Hub.

Before you can apply this Pulumi program, make sure you have installed Pulumi and set up your OpenShift cluster's `kubectl` context.

After completing the setup, run the following commands from the same directory as the Pulumi program:

- `pulumi stack init <stack-name>` to create a new stack for this deployment.
- `pulumi up` to preview and deploy the changes defined in the Pulumi program. This command will actually deploy the `jira-service-desk-operator` Helm chart to your OpenShift cluster.

The `statusUrl` export is a placeholder to show how you can extract useful information from the deployed resources. It assumes there's a `Service` object with a load balancer provisioned. In reality, you would replace this with actual resource names and properties relevant to the Jira Service Desk Operator Helm chart.
