Deploy the argocd-operator helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Argo CD operator Helm chart on an OpenShift cluster using Pulumi, you'll need the Pulumi Kubernetes provider, which allows you to manage Kubernetes resources with Pulumi programs. The example provided will demonstrate how to use the `Chart` resource from the Pulumi Kubernetes provider to deploy the Argo CD operator Helm chart.

Before running the following program, ensure that you have configured your Pulumi environment to use the OpenShift cluster where you want to deploy the chart. Typically, this involves setting up your `kubeconfig` file correctly, so that Pulumi can communicate with your OpenShift cluster.

Here is a Pulumi program in TypeScript that accomplishes the deployment of the Argo CD operator Helm chart:

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

// Define the settings for the Argo CD operator Helm chart
const argoCDChartSettings = {
    namespace: "argocd", // The target namespace for deployment
    repo: "https://argoproj.github.io/argo-helm", // The Helm chart repository
    chart: "argo-cd", // The name of the chart
    version: "3.2.3", // The version of the chart to deploy
    values: {
        // Add any custom values here that you want to override.
        // For example, enabling the OpenShift integration:
        openshift: {
            enabled: true,
        },
    },
};

// Create a new Helm chart resource to deploy Argo CD
const argoCDChart = new k8s.helm.v3.Chart("argocd-operator", argoCDChartSettings);

// Export the name of the namespace argoCD is deployed into
export const argocd_namespace = argoCDChartSettings.namespace;
```

In this program:

- We start by importing the `@pulumi/kubernetes` package.
- We create `argoCDChartSettings` which contains:
  - `namespace`: The namespace in which you want to deploy the Argo CD operator. Namespaces in Kubernetes act like a virtual cluster within your OpenShift cluster, enabling you to partition resources.
  - `repo`: This is the URL of the repository where the Helm chart is stored.
  - `chart`: The name of the chart that you want to deploy. In this case, it is "argo-cd" from the "argoproj" repository.
  - `version`: The specific version of the chart you wish to deploy. It’s generally a good practice to pin chart versions to ensure repeatable deployments.
  - `values`: A dictionary containing the values that you want to override in the default chart configuration. Here, the example sets the `openshift.enabled` value to `true` to customize the chart for OpenShift.
- We then use the `k8s.helm.v3.Chart` resource to create an instance of the Argo CD operator Helm chart in your cluster with the specified settings.
- Lastly, we export the namespace as a stack output, so you know where the Argo CD operator was deployed.

To run this program, you would need to have Pulumi installed and configured for your desired environment, and you would typically execute `pulumi up` to start the deployment process. Pulumi would show you a preview of the resources to be created and prompt for confirmation before applying the changes to your cluster.

Please ensure you have the necessary permissions on your OpenShift cluster to deploy Helm charts and create the resources that the Argo CD Helm chart requires.
