Deploy the cosi-driver-nutanix helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the `cosi-driver-nutanix` helm chart on AWS EKS using Pulumi, we will take the following steps:

1. Set up an EKS cluster using the `eks.Cluster` resource.
2. Create an IAM role for the EKS cluster so that EKS can make calls to other AWS services on your behalf.
3. Deploy the `cosi-driver-nutanix` helm chart to the EKS cluster.

First, we set up the EKS cluster and configure the necessary IAM roles. We use the `eks` package because it provides higher-level abstractions for working with EKS on AWS which simplifies the cluster creation process. Here's how we would define an EKS cluster and the associated IAM role in Pulumi using TypeScript:

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

// Create an Amazon EKS cluster.
const cluster = new eks.Cluster("my-cluster", {
    // Define your cluster’s configuration settings here
    // like the version of Kubernetes, the instance types for nodes, etc.
});

// Create a Kubernetes provider that uses our EKS cluster.
// This provider is used to deploy the Helm chart in the next step.
const k8sProvider = new k8s.Provider("k8s-provider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});
```

In the above code, we initialize an EKS cluster with default settings. You may want to customize it to suit your organizational needs, such as specifying the instance types or desired count of nodes, or particular Kubernetes versions.

After setting up the cluster, we will deploy the `cosi-driver-nutanix` helm chart. We would use the `k8s.helm.v3.Chart` resource, which allows us to deploy Helm charts into a Kubernetes cluster managed by Pulumi:

```typescript
// Deploy the cosi-driver-nutanix Helm chart using the Kubernetes provider tied to our EKS cluster.
new k8s.helm.v3.Chart("cosi-driver-nutanix-chart", {
    chart: "cosi-driver-nutanix",
    // You need to specify the appropriate Helm repo here where cosi-driver-nutanix is hosted
    fetchOpts: {
        repo: "https://helm-repo-url/",
    },
    // Any values to override in the chart can be specified here.
    values: {},
}, { provider: k8sProvider });
```

Above, we deploy the `cosi-driver-nutanix` helm chart to our EKS cluster. You will need to replace `https://helm-repo-url/` with the actual Helm repository URL where the `cosi-driver-nutanix` chart is hosted. Also, you might need to specify certain values to customize your Helm chart deployment, which you can do within the `values` object.

Now you can run `pulumi up` to provision the EKS cluster and deploy your Helm chart. This process may take a few minutes to complete.

Additionally, make sure to check the Helm chart's documentation for any prerequisites or configurations needed specifically for the `cosi-driver-nutanix` chart, as these may need to be addressed in the `values` object or elsewhere in your Pulumi code.
