Deploy the cryostat helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the Cryostat Helm chart on an AWS Elastic Kubernetes Service (EKS) cluster, we'll perform a few steps within our Pulumi program:

1. Set up an EKS cluster using the `eks.Cluster` resource.
2. Once the cluster is provisioned, we will configure `kubectl` to interact with the cluster by using the generated kubeconfig.
3. Deploy the Cryostat Helm chart using the `helm.v3.Chart` resource, which requires us to have a Helm chart available for Cryostat.

Below is a Pulumi program written in TypeScript that will perform these steps. This program assumes you have AWS credentials configured and necessary permissions to create EKS clusters and deploy resources.

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

// Create an EKS cluster
const cluster = new eks.Cluster("myEksCluster", {
    instanceType: "t2.medium",
    desiredCapacity: 2,
    minSize: 1,
    maxSize: 3,
});

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

// Create a k8s provider using the cluster's kubeconfig
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.kubeconfig.apply(JSON.stringify),
});

// Deploy the Cryostat Helm chart
const cryostatChart = new k8s.helm.v3.Chart("cryostat", {
    fetchOpts: {
        repo: "https://some-helm-chart-repo", // Replace with the actual Helm repo URL
    },
    // Specify the Helm chart, version, and values
    chart: "cryostat",
    version: "1.0.0", // Replace with the correct chart version
    values: {
        // Provide necessary values here
    },
}, { provider: k8sProvider });

// When running this Pulumi program, it will provision a new EKS cluster using the `eks.Cluster` resource.
// It uses the `kubernetes` package to deploy the Cryostat Helm chart to the newly created EKS cluster.

// To run this program:
// - Install Pulumi (https://www.pulumi.com/docs/get-started/aws/begin/)
// - Configure your AWS credentials (https://www.pulumi.com/docs/intro/cloud-providers/aws/setup/)
// - Install Node.js and NPM (https://nodejs.org/)
// - Create a new directory, run `pulumi new typescript`, and replace the contents of `index.ts` with this program
// - Run `npm install @pulumi/eks @pulumi/pulumi @pulumi/kubernetes`
// - Run `pulumi up` to deploy your infrastructure

// Replace "https://some-helm-chart-repo" with the actual repository URL where the Cryostat Helm chart can be found.
// Ensure you specify the correct Helm chart name and version along with any necessary values corresponding to the Cryostat Helm chart.
```

Please make sure to replace the placeholder values with the actual details. For example, the `chart` and `version` should point to the proper Cryostat Helm chart version you wish to deploy. Similarly, if the Cryostat chart requires specific configuration values, populate the `values` field accordingly within the `helm.v3.Chart` resource.

After crafting the program above, you can run it by following the commented instructions at the bottom of the code block. This will set up the infrastructure on AWS and deploy the required Helm chart onto the EKS cluster. Remember that deploying and managing Kubernetes resources can incur costs in your AWS account, so ensure you understand the pricing details and have configured the resources according to your budget and requirements.
