1. Deploy the trivy-sbom helm chart on Azure Kubernetes Service (AKS)


    Deploying the trivy-sbom Helm chart on Azure Kubernetes Service involves several steps. The process consists of setting up an AKS cluster, integrating it with a container registry if required, and then using Helm to deploy the chart to the cluster.

    Below is an outline of the Pulumi program we're going to write in TypeScript:

    1. Creating the AKS Cluster: We'll define the desired AKS cluster configuration, such as node size, node count, and other relevant Kubernetes settings using the azure.containerservice.KubernetesCluster resource.

    2. Deploying trivy-sbom using Helm: Once we have our AKS cluster up and running, we'll deploy the trivy-sbom Helm chart using Pulumi's kubernetes.helm.v3.Chart resource, which facilitates deploying Helm charts into a Kubernetes cluster.

    Let's start by setting up our Pulumi program to create the AKS cluster.

    import * as pulumi from '@pulumi/pulumi'; import * as azure from '@pulumi/azure'; import * as k8s from '@pulumi/kubernetes'; // Step 1: Create an AKS cluster const resourceGroup = new azure.core.ResourceGroup('aksResourceGroup'); const aksCluster = new azure.containerservice.KubernetesCluster('aksCluster', { resourceGroupName: resourceGroup.name, location: resourceGroup.location, defaultNodePool: { name: 'default', nodeCount: 2, vmSize: 'Standard_D2_v2', }, dnsPrefix: `${pulumi.getStack()}-k8s`, identity: { type: 'SystemAssigned', }, }); // Export the kubeconfig export const kubeconfig = aksCluster.kubeConfigRaw;

    Now that we have defined an AKS cluster, we can use Pulumi's kubernetes provider to deploy the trivy-sbom Helm chart. We'll import this Helm chart using the kubernetes.helm.v3.Chart resource, as shown in the code snippet below.

    // Step 2: Deploy the "trivy-sbom" Helm chart to the AKS cluster // Create a k8s provider using the AKS kubeconfig. const k8sProvider = new k8s.Provider('k8sProvider', { kubeconfig: aksCluster.kubeConfigRaw, }); // Deploy "trivy-sbom" Helm chart const trivySbomChart = new k8s.helm.v3.Chart('trivy-sbom', { chart: 'trivy-sbom', version: '0.1.0', // specify the version of the chart if necessary namespace: 'security', // specify the namespace where the chart will be installed fetchOpts: { repo: 'https://aquasecurity.github.io/helm-charts/', // specify the Helm chart repository }, }, { provider: k8sProvider }); // Export the chart name export const chartName = trivySbomChart.name;

    In this Pulumi program:

    • We create a new resource group for our AKS cluster using azure.core.ResourceGroup.
    • We set up an AKS cluster with azure.containerservice.KubernetesCluster, specifying the node count and size, as well as other configurations like dnsPrefix. The system-assigned identity is used for the AKS cluster.
    • The cluster's kubeconfig is exported to enable us to interact with it using kubectl or to integrate with CI/CD systems.
    • We create a k8s.Provider which dictates the Kubernetes cluster that our Helm chart should be deployed to.
    • We deploy the trivy-sbom Helm chart to our AKS cluster with k8s.helm.v3.Chart, where its fetchOpts property points to the Helm chart's repository.

    You will see that we exported the kubeconfig and the chartName. Exporting these values can be beneficial. For example, kubeconfig allows access to the cluster with tools like kubectl, and chartName provides a reference to the deployed Helm chart that can be useful for monitoring or further automation tasks.

    Remember to replace trivy-sbom and 0.1.0 with the correct chart name and version you wish to deploy. Also, be sure to use the correct Helm chart repository URL (if trivy-sbom has a different source). In this program, we have assumed that trivy-sbom is available in the specified repository and provided a version and namespace to fit the context of the deployment.

    This program should provide a fully functional starting point for deploying the trivy-sbom Helm chart to AKS with Pulumi. Each line has comments to help you understand what's happening at each step. Run this program with Pulumi's usual workflow (pulumi up), and it will provision the infrastructure and deploy the Helm chart as described.
