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

Question

Pulumi · Accepted Answer

To deploy the Tracee Helm chart on Azure Kubernetes Service (AKS), you need to perform the following high-level steps:

1. Create an AKS cluster if you don't already have one.
2. Configure Pulumi to use the Kubernetes provider to interact with the AKS cluster.
3. Deploy the Tracee Helm chart to the AKS cluster using Pulumi's Helm support.

Below, you'll find a detailed TypeScript program that performs these steps with Pulumi. The program does the following:

- Sets up an AKS cluster using `@pulumi/azure-native` package.
- Gets kubeconfig from the created AKS instance.
- Installs the Tracee Helm chart on the AKS cluster using `@pulumi/kubernetes` package.

Before you begin:

Ensure that you have Azure CLI and Pulumi CLI installed and configured with appropriate access permissions.

Here is a TypeScript program that accomplishes these steps:

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

// Step 1: Create an AKS cluster
const resourceGroupName = new azure_native.resources.ResourceGroup("rg", {
    resourceGroupName: "traceeAKSResourceGroup",
    location: "East US",
});

const k8sCluster = new azure_native.containerservice.ManagedCluster("aksCluster", {
    resourceGroupName: resourceGroupName.name,
    location: resourceGroupName.location,
    agentPoolProfiles: [{
        count: 2,
        mode: "System",
        vmSize: "Standard_DS2_v2",
        name: "agentpool"
    }],
    dnsPrefix: "traceeaks",
});

// Export the KubeConfig
const creds = pulumi.all([resourceGroupName.name, k8sCluster.name]).apply(([rgName, clusterName]) => 
    azure_native.containerservice.listManagedClusterUserCredentials({
        resourceGroupName: rgName,
        resourceName: clusterName,
}));

const kubeconfig = creds.kubeconfigs[0].value.apply(v => Buffer.from(v, 'base64').toString());

// Step 2: Create a Kubernetes provider pointing to the AKS cluster
const k8sProvider = new k8s.Provider("aksK8s", {
    kubeconfig: kubeconfig,
});

// Step 3: Deploy the Tracee Helm chart using the Kubernetes provider
const traceeChart = new k8s.helm.v3.Chart("tracee", {
    chart: "tracee",
    version: "0.1.0", // Specify the version of Tracee you wish to deploy
    fetchOpts: {
        repo: "https://aquasecurity.github.io/helm-charts/", // Helm chart repository for Tracee
    },
}, { provider: k8sProvider });

// Export the Kubernetes cluster name and kubeconfig
export const aksClusterName = k8sCluster.name;
export const kubeconfigAsString = kubeconfig;
```

### Explanation:

- We create an Azure Resource Group `traceeAKSResourceGroup` to help manage all our Azure resources in one place.
- We then create an AKS cluster `aksCluster` with a system node pool with two virtual machine instances.
- We retrieve the KubeConfig credentials from Azure, which will allow us to interact with the Kubernetes cluster.
- Using the KubeConfig credentials, we set up a Pulumi Kubernetes provider to handle resources in the AKS cluster.
- Finally, we deploy the Tracee Helm chart to the AKS cluster. The repository URL `https://aquasecurity.github.io/helm-charts/` is where the Helm chart for Tracee is hosted.

The `kubeconfig` is exported, which is useful to use `kubectl` from the local machine to interact with your Kubernetes cluster.

Run the Pulumi program using the command `pulumi up`. It prompts for confirmation before proceeding to create the resources in Azure.

Remember that Azure and Kubernetes resources will incur costs, and you should delete the resources with `pulumi destroy` when you're done to avoid unnecessary charges.
