Deploy the argo-cr helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the Argo CD Helm chart on a Kubernetes cluster using Pulumi, you will need to use the `Chart` resource from the `@pulumi/kubernetes` package. The Chart resource allows you to deploy a Helm chart from various sources such as a Helm repository, a local directory, or even from a tarball.

Below is a Pulumi program written in TypeScript that demonstrates how you can deploy the Argo CD Helm chart onto a Kubernetes cluster. This program assumes that you have already configured Pulumi with access to your Kubernetes cluster and that you have Helm installed.

We will use the Argo CD Helm chart available from the official Argo project's Helm repository. Here's how to do it:

1. You first need to import the necessary libraries from Pulumi and define your Kubernetes provider.
2. You then create a new Chart resource, specifying the chart name (`argo-cd`), the version, and any custom values you wish to override.

Here is the complete TypeScript program:

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

// Create a new instance of the Argo CD Helm chart.
const argoCdChart = new k8s.helm.v3.Chart("argo-cd", {
    chart: "argo-cd",
    version: "3.26.3", // Specify the version of the Argo CD chart you wish to deploy
    fetchOpts: {
        repo: "https://argoproj.github.io/argo-helm", // The repository where the Argo CD chart is located
    },
    // Include any custom values you wish to set for the Argo CD Helm chart
    // Refer to the chart's values.yaml file or the associated documentation for available options.
    values: {
        server: {
            service: {
                type: "LoadBalancer",
            },
        },
    },
});

// Export the name of the chart deployment and other resources you might want to know about.
export const argoCdChartName = argoCdChart.getResourceName("v1/Service", "argo-cd/argo-cd-server");
```

In the `values` object, you have the option to customize your Argo CD deployment. In this example, we're specifying that the Argo CD server should be exposed via a LoadBalancer service, which is suitable for cloud-based Kubernetes clusters. For different configurations or environments, you might want to choose different service types like `ClusterIP` or `NodePort`, or even configure ingress.

Make sure to replace the `version` with your desired version of Argo CD Helm chart. You can find the available versions listed in the [Argo project's chart repository](https://argoproj.github.io/argo-helm/).

Once you've written the program:

1. Save this code in a file, for example, `index.ts`.
2. Open your terminal.
3. Navigate to the directory where you saved the file.
4. Run `pulumi up` to preview and deploy the resources.

The command will show a preview of the resources that will be created, and you can confirm to proceed with the actual deployment. After the deployment completes, any output such as the name of the Argo CD server service will be displayed.

Remember to manage the deployed Helm chart appropriately, making sure that your cluster has enough resources to host Argo CD and that your configurations follow best practices for security and scalability.
