1. Deploy the opencve helm chart on Digital Ocean Kubernetes Service

    TypeScript

    To deploy the OpenCVE helm chart on the DigitalOcean Kubernetes Service using Pulumi, you will need to perform a series of steps. First, you'll need to create a Kubernetes cluster on DigitalOcean. Once the cluster is ready, you'll use Pulumi's Kubernetes provider to deploy the OpenCVE helm chart to the cluster.

    The following is a program written in TypeScript that accomplishes this task. Make sure you have Pulumi installed and configured with the appropriate cloud provider credentials.

    I'll walk you through each step of the process:

    1. Define Your Kubernetes Cluster: Using digitalocean.KubernetesCluster, you create a new Kubernetes cluster in a specified region with the desired node size and count.

    2. Install Helm Chart: You leverage the Pulumi Kubernetes provider to deploy the Helm chart for OpenCVE by creating a Chart resource. You'll need to specify the chart name, and you may also specify version and values to customize the deployment according to your needs.

    3. Export the Kubernetes Config: Once the cluster is created, you can export the Kubernetes configuration file, which can be used with kubectl to interact with your Kubernetes cluster directly.

    Now let's see the Pulumi program that does all of this.

    import * as pulumi from "@pulumi/pulumi"; import * as digitalocean from "@pulumi/digitalocean"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Create a DigitalOcean Kubernetes cluster const cluster = new digitalocean.KubernetesCluster("opencve-cluster", { region: "nyc1", version: "latest", nodePool: { name: "opencve-pool", size: "s-1vcpu-2gb", // Adjust the size according to your requirements nodeCount: 1, // Adjust the node count as needed }, }); // Step 2: Deploy the OpenCVE helm chart using the kubernetes provider const opencveChart = new k8s.helm.v3.Chart("opencve", { chart: "opencve", version: "1.0.0", // Specify the chart version if needed //fetchOpts: { // Uncomment these lines if you have to specify a custom repository // repo: "<repository URL>", //}, namespace: "default", }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeConfigs[0].rawConfig }) }); // Step 3: Export the Kubernetes cluster's kubeconfig which can be used with 'kubectl' export const kubeconfig = cluster.kubeConfigs[0].rawConfig; // Run `pulumi up` to deploy the cluster and OpenCVE chart. // After deployment, run `pulumi stack output kubeconfig > kubeconfig.yaml` to save the kubeconfig to a file. // You can then use `kubectl --kubeconfig ./kubeconfig.yaml` to interact with your cluster.

    Let's break down the Pulumi program above:

    • We import the required Pulumi packages (@pulumi/pulumi, @pulumi/digitalocean, @pulumi/kubernetes) to work with DigitalOcean and Kubernetes resources.
    • We create a DigitalOcean Kubernetes cluster by specifying the region, version, and node pool configuration.
    • We deploy the OpenCVE helm chart to our Kubernetes cluster using Pulumi's Helm support. Note that we've commented out the repository URL configuration since OpenCVE helm chart's default repository can typically be used. If OpenCVE's Helm chart is hosted on a custom Helm repository, you need to provide the repository URL.
    • We export the kubeconfig of the Kubernetes cluster as a stack output. You can use this config file to interact with your cluster using kubectl.

    To execute this Pulumi program, save the code to a file (e.g., index.ts), run pulumi up, and follow the CLI prompts to deploy your infrastructure. After the deployment is successful, you'll get the kubeconfig output, which you can use to interact with your Kubernetes cluster and verify the OpenCVE deployment.

    Remember, you may need to adjust the node size, node count, Helm chart version, or namespace according to your specific requirements for the OpenCVE deployment.
