Deploy the thehive helm chart on AWS EKS

Question

Pulumi · Accepted Answer

To deploy the TheHive helm chart on AWS EKS (Elastic Kubernetes Service), we're going to follow these steps:

Create an EKS Cluster: We'll start by creating an EKS cluster where our Kubernetes workloads will run. We'll use the eks.Cluster resource to create this cluster.
Deploy TheHive Helm Chart: After having our EKS cluster ready, we'll deploy TheHive using a helm chart. To deploy applications using Helm charts in Pulumi, we use the kubernetes.helm.v3.Chart resource.

Now, let me walk you through the actual Pulumi program to achieve this deployment. Make sure you have AWS configured with the necessary access rights and Pulumi installed. This program assumes that you have an existing VPC and subnets you wish to use. If not, you'll need to create these as well or let Pulumi manage them for you.

The eks.Cluster resource is part of the @pulumi/eks package that provides a Pulumi component for creating an EKS cluster. The kubernetes.helm.v3.Chart is part of the @pulumi/kubernetes package, which provides resources for managing Kubernetes resources using Pulumi.

Here is a complete TypeScript program that will set up an EKS cluster and deploy TheHive to it:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";
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", {});

// Export the cluster's kubeconfig.
export const kubeconfig = cluster.kubeconfig.apply(JSON.stringify);

// Define the Helm chart for TheHive deployment.
const theHiveChart = new k8s.helm.v3.Chart("thehive", {
    chart: "thehive",
    version: "<ENTER_CHART_VERSION>", // Specify the chart version you want to deploy
    fetchOpts: {
        repo: "https://<ENTER_HELM_REPO_URL>", // Specify the Helm chart repository URL
    },
    // You may include additional configuration here as needed.
});

// Export the public endpoint for the TheHive deployment
export const theHiveEndpoint = cluster.endpoint;

Here's an explanation of what each part of this code does:

We import the required packages (pulumi, aws, eks, kubernetes).
We create an EKS cluster using eks.Cluster with a default configuration. This will set up the necessary VPC, subnets, and node groups required for an EKS cluster.
We export kubeconfig which is needed to interact with the cluster via kubectl or any Kubernetes client.
We create a Helm chart resource (k8s.helm.v3.Chart) to deploy TheHive. You'll need to replace <ENTER_CHART_VERSION> and <ENTER_HELM_REPO_URL> with the appropriate version number of the chart and the URL of the Helm repository that contains TheHive chart respectively.
Finally, we export the public endpoint of the EKS cluster, which can be used to access TheHive once it's deployed.

Remember to replace the placeholders with actual values. If you're not sure about the version number or the Helm repository URL for TheHive, you should look it up in the Helm chart's documentation or a Helm repository that hosts the chart.

To run this program, save it to a index.ts file, and use the following commands:

pulumi stack init dev                     # to create a new stack called 'dev'
pulumi config set aws:region us-west-2    # to set the AWS region, choose the one that suits you
pulumi up                                 # to preview and deploy the changes

This should give you a running EKS cluster with TheHive deployed, ready for you to configure and start using for your security incident response needs.
