Deploy the kubernetes-mixin helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `kubernetes-mixin` Helm chart on an AWS EKS cluster using Pulumi, we need to follow these steps:

1. Provision an EKS cluster.
2. Configure Pulumi to use the AWS and Kubernetes providers.
3. Deploy the `kubernetes-mixin` Helm chart to the EKS cluster.

First, you need to have Pulumi installed and set up, along with the AWS CLI configured for the relevant AWS account and region you wish to deploy the cluster in. Please ensure you have the necessary permissions to create the AWS EKS cluster and all related resources.

Next, we'll write a program in TypeScript. Here's how each part of the program works:

- `awsx.eks.Cluster`: This higher-level component creates an EKS cluster. We'll use this instead of the lower-level `aws.eks.Cluster` as it sets up the VPC and other necessary components with sensible defaults.
- `kubernetes.helm.sh/v3.Chart`: After creating the cluster, we use this resource to deploy a Helm chart into our EKS cluster. We'll specify the `kubernetes-mixin` chart.

Below is the TypeScript program which will set up the EKS cluster and deploy the Helm chart:

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

// Create an EKS cluster with the default configuration.
const cluster = new awsx.eks.Cluster('my-cluster', {
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
    instanceType: "t2.medium", // You can choose the instance type that suits your needs
});

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

// Create a Kubernetes provider that uses our EKS cluster's kubeconfig.
const k8sProvider = new k8s.Provider('k8s-provider', {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the kubernetes-mixin Helm chart.
const chart = new k8s.helm.v3.Chart('kubernetes-mixin', {
    chart: "kubernetes-mixin", // Replace with the correct chart name or path if it's different
    version: "0.1.0", // Specify the chart version you want to deploy
    fetchOpts: { repo: "https://kubernetes-mixins.github.io/" }, // Replace with the URL of the chart repository
}, { provider: k8sProvider });

// Once the program is successfully executed, you will have the `kubernetes-mixin` chart deployed on your EKS cluster.
```

After writing this program in a file, say `index.ts`, you would run it using the Pulumi CLI:

```bash
pulumi up
```

This command will prompt you to confirm the actions Pulumi plans to take. Upon confirmation, it will provision the EKS cluster and then deploy the specified Helm chart. Keep in mind that provisioning an EKS cluster and deploying a Helm chart can take several minutes.

Please replace `"kubernetes-mixin"`, `"0.1.0"`, and `"https://kubernetes-mixins.github.io/"` with the actual values that match the Helm chart you want to deploy.

You can check the status of the EKS cluster and the Helm release using Pulumi's command-line interface or through the Pulumi Console.

This program is a starting point, and you may need to customize it further to fit with the network setup and configuration specifics required by your organization or the specific Helm chart you're deploying.
