Deploy the schildichat-web helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `schildichat-web` Helm chart on AWS EKS using Pulumi, you will perform the following steps:

1. Create an Amazon EKS cluster using the `awsx` library, which is a higher-level abstraction over the `aws` provider. This simplifies creating and managing an EKS cluster.
2. Deploy the Helm chart onto the EKS cluster using Kubernetes provider from Pulumi.

For this task, you will use two Pulumi resources:
- `eks.Cluster`: To create and configure the Amazon EKS cluster. ([Documentation](https://www.pulumi.com/registry/packages/eks/api-docs/cluster/))
- `kubernetes.helm.v3.Chart`: To deploy the `schildichat-web` Helm chart onto the EKS cluster. ([Documentation](https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm/v3/chart/))

Below is the TypeScript program that demonstrates these steps:

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

// Step 1: Create an EKS cluster
const cluster = new eks.Cluster("my-cluster", {
    desiredCapacity: 2, // Set the number of worker nodes
    minSize: 1,
    maxSize: 3,
    deployDashboard: false, // Dashboard is not recommended in production
});

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

// Step 2: Deploy the schildichat-web Helm chart onto the EKS cluster
// We will use the kubeconfig from the created EKS cluster to interact with it
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig,
});

// Note: You need to specify the correct repository or chart location and any necessary values
const schildichatChart = new k8s.helm.v3.Chart("schildichat-web", {
    chart: "schildichat-web",
    // If your Helm chart is in a Helm repository, you have to add 'repo' attribute here
    // repo: "<repository_url>",
    // If the Helm chart requires custom values, you provide them here
    values: {
      // Specify any required configuration values for your Helm chart
    },
}, { provider: k8sProvider });

// Export the address of the web application
export const webAppUrl = "http://" + cluster.endpoint;
```

This will set up your EKS cluster and deploy the Helm chart. Please replace the placeholders for the chart repository URL and configuration values, if needed.

Please make sure that your Pulumi installation is configured for TypeScript, and you have the AWS CLI configured with the necessary credentials. After that, you may run this program using the `pulumi up` command in your terminal. It will automatically create the resources in the correct order and manage dependencies between them.
