Deploy the crossplane-controllers helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Crossplane Controllers Helm chart on an OpenShift cluster using Pulumi, you would write a program using Pulumi's Kubernetes provider. The `kubernetes.helm.v3.Chart` resource is specifically designed to deploy Helm charts to a Kubernetes cluster, which OpenShift is a distribution of.

Firstly, you would need to configure your local environment to connect with the OpenShift cluster. This involves setting up `kubectl` to connect to your OpenShift cluster. Pulumi utilizes the same configuration as `kubectl`, so once `kubectl` is configured and can interact with your cluster, so can Pulumi.

In the Pulumi program, you will define a Helm chart resource, specifying the necessary chart name, version, and any custom configuration parameters required for the Crossplane Controllers chart.

Below is a TypeScript program using Pulumi to deploy the Crossplane Controllers Helm chart to an OpenShift cluster. This code assumes you have the chart details such as name, and version (If you have a custom repository for Crossplane Controllers, you would specify it with the `repo` field and give it the repository URL):

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

const crossplaneChart = new k8s.helm.v3.Chart("crossplane-controllers", {
    // Assuming 'crossplane-controllers' is the chart name.
    // Make sure to use the exact chart name as published in the Helm repository you are using.
    chart: "crossplane-controllers",
    // Specify the version of the chart you want to deploy.
    version: "x.y.z", // Use the appropriate chart version.
    // Add any custom configuration in the 'values' field.
    // This depends on what the specific Helm chart for Crossplane Controllers requires.
    values: {
        // Custom values go here. For example:
        // replicaCount: 2,
    },
    // Specify the namespace where this chart should be installed (if not default).
    // OpenShift may require a specific project or namespace for certain deployments.
    namespace: "my-crossplane-namespace",
    // If your Helm chart is stored in a private repository or a place that needs authentication,
    // specify the 'repo' property with the repository URL.
    // repo: "https://charts.crossplane.io/stable",
});

// Export the chart name of the deployed Crossplane Controllers for easy reference.
export const crossplaneChartName = crossplaneChart.metadata.apply(metadata => metadata.name);
```

To run the above Pulumi program, you would:

1. Install the Pulumi CLI and set up your Pulumi account.
2. Have Node.js installed along with a package manager such as npm or Yarn to handle TypeScript dependencies.
3. Initialize a new Pulumi project for TypeScript (`pulumi new typescript`).
4. Install the `@pulumi/kubernetes` package as a dependency (`npm install @pulumi/kubernetes`).
5. Replace the content of `index.ts` in your Pulumi project with the above program.
6. Replace `"x.y.z"` with the actual version of the Crossplane Controllers Helm chart you want to deploy.
7. Run `pulumi up` after ensuring your `kubectl` is configured to connect to your OpenShift cluster.

When you run `pulumi up`, Pulumi will reach out to your OpenShift cluster and initiate the deployment of the Crossplane Controllers Helm chart as specified in the program. The output will show you the changes being made, and you can confirm the deployment to proceed. After successful deployment, Pulumi will show you the state of the resources and any exports defined, such as `crossplaneChartName`.
