Deploy the thehive helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the TheHive Helm chart on Kubernetes using Pulumi, we will follow these steps:

1. Set up a Pulumi program in TypeScript.
2. Use the Kubernetes provider from Pulumi to interact with your Kubernetes cluster.
3. Use the Helm Chart resource to deploy TheHive Helm chart from the Pulumi Kubernetes provider.

Here is an outline of the details:

- We will use the `Chart` resource from the Pulumi Kubernetes provider which allows us to manage Helm charts as part of our Pulumi application. This resource can install, upgrade, and delete Helm charts from any source such as the public Helm repo, a private Helm repo, or a local chart.

- Helm charts are packages for Kubernetes resources. TheHive is a scalable, open-source, and free Security Incident Response Platform designed to make life easier for SOCs, CSIRTs, CERTs, and any information security practitioners.

- You must have a Kubernetes cluster running and `kubectl` configured to communicate with the cluster. Pulumi uses the same configuration as `kubectl`, so if it's already set up and working, Pulumi should work out of the box.

Let's construct the Pulumi program to deploy TheHive Helm chart to your Kubernetes cluster. We will assume that you have already set up a Kubernetes cluster and configured `kubectl`.

Here is an example TypeScript program that performs this deployment:

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

// Create an instance of the Kubernetes Chart class to deploy TheHive Helm chart.
const theHiveChart = new k8s.helm.v3.Chart("thehive", {
    // Specify the chart repository. If TheHive chart is in a custom repo, you need to set the `repo` property.
    chart: "thehive",
    // Optionally, you can specify the version of the chart you want to deploy.
    // version: "x.y.z", // Replace `x.y.z` with the desired chart version.
    // You may need to pass specific values to TheHive chart to configure it according to your needs.
    // values: {
    //     property1: "value1",
    //     property2: "value2",
    // },
    // Specify the Kubernetes namespace where you want to deploy TheHive.
    // If omitted, it defaults to the "default" namespace.
    // namespace: "thehive-namespace",
});

// Export the base URL where TheHive is accessible once it's deployed.
// This may vary depending on your Kubernetes service setup and Ingress configuration,
// and you need to replace 'thehive-service' and 'namespace' accordingly.
export const theHiveUrl = theHiveChart.getResourceProperty("v1/Service", "thehive-service", "status").apply(status => {
    const ingress = status.loadBalancer.ingress[0];
    return ingress.hostname || ingress.ip;
});
```

This code loads the Pulumi library for Kubernetes and creates a Helm chart resource for deploying TheHive. You can customize the `values` property with any required Helm values. Additionally, we are exporting the URL under which TheHive would be accessible. Replace `'thehive-service'` and `'namespace'` with the actual service name and namespace where TheHive will be deployed.

To run this program:

- Install the Pulumi CLI and set up your Pulumi project and stack if you haven't already.
- Ensure you have Node.js and npm installed to work with TypeScript.
- Place the code in a file with a `.ts` extension, for example, `index.ts`.
- Run `npm install` to install the necessary dependencies (such as `@pulumi/kubernetes`).
- Execute `pulumi up` to preview and deploy the changes.

Pulumi will communicate with your Kubernetes cluster to deploy TheHive Helm chart based on the configuration provided. After the deployment, it will output the base URL for accessing TheHive. Make sure to configure any Ingress controller or service type as needed to make TheHive accessible as desired.
