1. Deploy the web-dvwa helm chart on Digital Ocean Kubernetes Service


    To deploy the web-dvwa Helm chart on DigitalOcean's Kubernetes Service using Pulumi, you will need to:

    1. Set up a DigitalOcean Kubernetes Cluster: First, create a Kubernetes Cluster on DigitalOcean. To achieve this, you'll define the cluster configuration with the required node pool settings.

    2. Use Helm Chart resource for deployment: Once the cluster is set up, you'll use Pulumi's helm.sh/v3.Chart resource which allows you to deploy Helm charts within a Kubernetes cluster. For the web-dvwa chart, you may need to add the appropriate Helm repository or specify the chart location directly if it's a custom Helm chart.

    Here's a Pulumi TypeScript program that demonstrates how to accomplish this:

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster. const cluster = new digitalocean.KubernetesCluster("do-cluster", { // Define the region, version and node pool details according to your needs. region: "nyc1", version: "latest", // You can specify the exact version of Kubernetes. nodePool: { name: "default-pool", size: "s-1vcpu-2gb", // Choose the size that fits your workload. nodeCount: 2, }, }); // Step 2: Create a Kubernetes provider instance using the kubeconfig from the newly created cluster. const k8sProvider = new kubernetes.Provider("do-k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig, }); // Step 3: Deploy the web-dvwa Helm chart into the Kubernetes cluster. const webDvwaChart = new kubernetes.helm.v3.Chart("web-dvwa", { chart: "dvwa", // Assuming 'dvwa' is the chart name in the repository. // The repository details where the web-dvwa Helm chart is located. // If the chart is within a known Helm repository, you must add that repo to your Helm CLI using `helm repo add`. // If this is a custom chart, you may need to specify the `repo` or handle the source differently. fetchOpts: { repo: "https://charts.example.com/", // Replace with the correct chart repository. }, }, { provider: k8sProvider }); // Export the cluster's kubeconfig and the service endpoint of the web-dvwa if available. export const kubeconfig = cluster.kubeConfigs[0].rawConfig; export const webDvwaEndpoint = webDvwaChart.getResourceProperty( "v1/Service", "web-dvwa", "status", ).apply(status => status.loadBalancer.ingress[0]?.hostname || status.loadBalancer.ingress[0]?.ip);


    • DigitalOcean Kubernetes Cluster: The digitalocean.KubernetesCluster resource is used to allocate a managed Kubernetes cluster in DigitalOcean's environment. This includes setting up node pools that define the size and count of the Droplets (VMs) that will run your Kubernetes worker nodes.

    • Kubernetes Provider: The kubernetes.Provider resource creates an instance of a Kubernetes provider which is configured to manage resources in the created cluster, using the cluster's kubeconfig.

    • Helm Chart: The kubernetes.helm.v3.Chart resource is responsible for deploying a Helm chart into the Kubernetes cluster. It requires the chart name and repository details. You will need to replace the chart and repo fields with the correct values for the web-dvwa Helm chart.

    • Exports: Pulumi exports are used to provide outputs that can be accessed after the deployment is completed. In this case, the kubeconfig for accessing the cluster and the endpoint of the web-dvwa service are exported.

    Ensure you have the DigitalOcean provider configured with the required credentials and Pulumi CLI installed locally. After running this program with pulumi up, the web-dvwa Helm chart is expected to be deployed on your DigitalOcean Kubernetes cluster. You can use the exported kubeconfig to manage the cluster with kubectl and the webDvwaEndpoint to access the application once it's deployed. Please make sure to adjust the chart name and repository details as per the actual Helm chart you are intending to deploy.
