Deploy the ibm-mobilefoundation-dev helm chart on AWS EKS

Question

Pulumi · Accepted Answer

Deploying a Helm chart on an Amazon EKS (Elastic Kubernetes Service) cluster involves several steps. Below is a guide on how to deploy the `ibm-mobilefoundation-dev` Helm chart using Pulumi and TypeScript. We will create an EKS cluster, install the Helm chart into it, and ensure all required AWS and Kubernetes resources are in place.

### Overview of Resources Used

1. `awsx.eks.Cluster`: Represents an EKS Kubernetes cluster. We will use this to create a new EKS cluster where the `ibm-mobilefoundation-dev` Helm chart will be deployed.

2. `kubernetes.helm.v3.Chart`: Represents a Helm chart. We will use this to deploy the `ibm-mobilefoundation-dev` chart onto our EKS cluster.

Here's the detailed Pulumi program:

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

// Create an EKS cluster with the default configuration. 
// The `eks.Cluster` class encapsulates the EKS cluster's control plane and default node group.
const cluster = new eks.Cluster("my-eks-cluster");

// Export the cluster's kubeconfig to connect to your cluster.
export const kubeconfig = cluster.kubeconfig;

// After the cluster is up and running, we can deploy the Helm chart.

// We'll create a new Kubernetes provider instance that uses our kubeconfig.
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the ibm-mobilefoundation-dev Helm chart.
const mobileFoundationChart = new k8s.helm.v3.Chart("ibm-mobilefoundation-dev-chart", {
    chart: "ibm-mobilefoundation-dev",
    // You can specify the Helm chart version to use, repository opts, and values here.
    // This example uses defaults. You may need to adjust the `values` based on the Helm chart's requirements.
    values: {
        // Chart-specific values: these need to be configured based on the Helm chart's requirements.
        // For example:
        // replicaCount: 1
    },
    // The namespace where this Helm chart will be deployed.
    // If it's not provided, the Helm chart will be installed in the default namespace.
    namespace: "default",
}, { provider });

// Export the resources.
export const chartName = mobileFoundationChart.name;
export const chartStatus = mobileFoundationChart.status;
```

This program sets up everything you need to deploy the `ibm-mobilefoundation-dev` Helm chart on an EKS cluster. It starts by creating an EKS cluster using the `eks.Cluster` resource, then sets up a Kubernetes provider with the kubeconfig obtained from our cluster that allows us to interact with the cluster's API.

Once the provider is in place, we use the `k8s.helm.v3.Chart` resource to actually deploy the `ibm-mobilefoundation-dev` Helm chart. The `values` field in the Chart resource should be customized as per the Helm chart's configurations that you wish to override or specify.

Here's a quick rundown of what this Pulumi program does:
- Creates an AWS EKS cluster using Pulumi's EKS package.
- Configures Pulumi with a Kubernetes provider that knows how to communicate with the EKS cluster.
- Deploys the `ibm-mobilefoundation-dev` Helm chart into the Kubernetes cluster with default settings.

Do note that you will need `kubectl` and `helm` command-line tools installed if you are planning to interact with the cluster or Helm manually in addition to using Pulumi.

After running the program with Pulumi, you'll have an EKS cluster running with the IBM Mobile Foundation developer edition deployed as a Helm chart, ready for you to configure and use for development.
