Deploy the thehive helm chart on Azure Kubernetes Service (AKS)

Question

Pulumi · Accepted Answer

To deploy the TheHive Helm chart on Azure Kubernetes Service (AKS), you'll first need to create an AKS cluster, then configure kubectl to communicate with the cluster, and finally deploy the Helm chart to the cluster. In Pulumi, we accomplish this in several steps using TypeScript:

Create an AKS Cluster: We use the ProvisionedCluster resource from the azure-native Pulumi package.
Configure Kubeconfig: We obtain the kubeconfig file from the created AKS cluster, which allows us to interact with our cluster through kubectl.
Deploy the Helm Chart: Using the Chart resource from Pulumi's @pulumi/kubernetes package, we deploy the TheHive Helm chart.

Below is a complete program that accomplishes these steps:

import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";
import * as k8s from "@pulumi/kubernetes";

// Create a resource group if you don't have one already
const resourceGroup = new azure_native.resources.ResourceGroup("myResourceGroup");

// Provision the AKS cluster
const cluster = new azure_native.containerservice.ManagedCluster("myAKSCluster", {
    resourceGroupName: resourceGroup.name,
    agentPoolProfiles: [{
        count: 1,
        vmSize: "Standard_DS2_v2",
        mode: "System",
    }],
    dnsPrefix: "mykube",
});

// Export the kubeconfig to access the AKS cluster
export const kubeconfig = cluster.kubeConfig;

// Kubernetes provider that uses our kubeconfig
const k8sProvider = new k8s.Provider("k8sProvider", {
    kubeconfig: cluster.kubeConfig.apply(kc => kc!)
}, { dependsOn: [cluster] }); // Depends on ensures that provider waits for cluster to be created

// Deploy TheHive Helm chart
const theHiveChart = new k8s.helm.v3.Chart("thehive", {
    chart: "thehive",
    version: "<CHART_VERSION>", // Specify the version of TheHive Helm chart you want to deploy
    fetchOpts:{
        repo: "<HELM_REPO_URL>", // Specify the URL of TheHive Helm chart repository
    }
}, { provider: k8sProvider });

// To access the name of the deployed chart
export const theHiveChartName = theHiveChart.name;

Let's break it down:

We create an instance of the Azure Resource Group to hold our AKS resources by using azure_native.resources.ResourceGroup.
We then define an AKS cluster with azure_native.containerservice.ManagedCluster. The properties we provide include the resource group name, the size of the VMs in the agent pool, and a DNS prefix. Modify these values according to your needs. You may also want to adjust the agent pool profile for the number and type of nodes you need for your workload.
After the cluster is provisioned, we export the Kubernetes configuration needed to manage the cluster with kubectl. The command cluster.kubeConfig.apply(kc => kc!) ensures that Pulumi fetches the kubeconfig dynamically upon cluster creation.
We create a Pulumi Kubernetes provider to interact with the AKS cluster. This provider is configured with the kubeconfig from the AKS cluster.
Finally, we define a Chart resource, which will install the TheHive Helm chart. Replace <CHART_VERSION> with the specific version of TheHive Helm chart you wish to deploy, and <HELM_REPO_URL> with the Helm repository URL where the TheHive chart can be downloaded.

You will need to create a stack using Pulumi to deploy this program properly. To do so, run pulumi stack init followed by pulumi up to initiate the deployment process.

Please ensure you've logged into Azure (az login) and set your default subscription if necessary before running the Pulumi commands.

Remember to replace placeholder values like <CHART_VERSION> and <HELM_REPO_URL> with actual values corresponding to TheHive Helm chart details.

When you run pulumi up, Pulumi provisions the resources in the correct order and outputs the name of the deployed Helm chart, indicating successful deployment. You can then use kubectl to interact with your AKS cluster and TheHive deployment.
