Deploy the ibm-db2warehouse helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `ibm-db2warehouse` Helm chart on AWS EKS using Pulumi, we will follow a multi-step process. First, we will establish an Amazon EKS cluster, which is a managed Kubernetes service provided by AWS. Next, we will use the Pulumi Kubernetes provider to deploy the `ibm-db2warehouse` Helm chart to the EKS cluster.

Here's a high-level overview of the steps we'll take in the Pulumi TypeScript program:

1. Create an EKS cluster using the `@pulumi/eks` package. This high-level package simplifies creating and managing an EKS cluster.
2. Deploy the `ibm-db2warehouse` Helm chart using the `@pulumi/kubernetes` package. This will handle the Helm release lifecycle on the EKS cluster.

Here is the detailed Pulumi program that accomplishes these steps:

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

// Create an EKS cluster with the default configuration.
const cluster = new eks.Cluster("my-cluster", {});

// Once the cluster is created, we can use its kubeconfig output to configure a Kubernetes provider instance.
const provider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the ibm-db2warehouse Helm chart using the Kubernetes provider.
// You'll need to specify the correct repository or local path where the Helm chart is located.
const db2WarehouseChart = new k8s.helm.v3.Chart("ibm-db2warehouse-chart", {
    // Replace with the correct repository and chart details for ibm-db2warehouse.
    chart: "ibm-db2warehouse",
    version: "CHART_VERSION", // Replace with the chart version you wish to deploy.
    fetchOpts: {
        repo: "https://CHART_REPOSITORY_URL", // Replace with the repository URL that hosts the ibm-db2warehouse chart.
    },
    // You can specify values for the Helm chart, such as overrides or custom configuration.
    values: {
        // Add specific configuration for ibm-db2warehouse if required.
    },
}, { provider });

// Export the cluster's kubeconfig and the Helm release status.
export const kubeconfig = cluster.kubeconfig;
export const db2WarehouseStatus = db2WarehouseChart.status;
```

Make sure you replace `CHART_VERSION` and `https://CHART_REPOSITORY_URL` with the correct details for the `ibm-db2warehouse` Helm chart. You can also add any other relevant Helm chart values under the `values` property if you need to customize your deployment.

This program will:

- Create an EKS cluster named `"my-cluster"`.
- Define a Pulumi Kubernetes provider that uses the kubeconfig from the created EKS cluster.
- Deploy the `ibm-db2warehouse` Helm chart to the EKS cluster with the specified chart version and repository URL.

After you have the TypeScript program ready, you can use Pulumi's CLI to create and manage the AWS infrastructure and Kubernetes resources:

1. Ensure you have installed the AWS CLI and Pulumi CLI, and have configured your AWS credentials.
2. Run `pulumi up` to have Pulumi create the resources as described by the program.
3. Once the resources are created, Pulumi will provide outputs, such as the cluster's kubeconfig, so you can interact with the cluster using `kubectl`.

Remember to carefully manage your AWS credentials and kubeconfig as they provide access to your cloud resources.
