1. Deploy the opencve helm chart on Linode Kubernetes Engine


    To deploy the OpenCVE helm chart on Linode Kubernetes Engine (LKE) using Pulumi, you will need to perform the following steps:

    1. Set up Pulumi with Linode: Ensure you have an account on Linode and have created a personal access token. Set up your environment with the Linode CLI or by using environment variables to authenticate Pulumi with your Linode account.

    2. Create a Kubernetes cluster on LKE: This involves declaring a Kubernetes cluster resource using the Pulumi Linode provider. You need to specify the desired region, Kubernetes version, and the node type, among other configurations.

    3. Install the OpenCVE helm chart: With your Kubernetes cluster set up, you will then use Pulumi's Kubernetes provider to deploy the OpenCVE helm chart. You will specify the chart name, possibly the helm repository where the chart is hosted, and any configuration values that are specific to OpenCVE.

    Here's a Pulumi TypeScript program that shows how you would declare your Kubernetes cluster on LKE and then deploy the OpenCVE helm chart:

    import * as pulumi from "@pulumi/pulumi"; import * as linode from "@pulumi/linode"; import * as kubernetes from "@pulumi/kubernetes"; // Step 1: Instantiate a Linode Kubernetes Engine cluster where we will deploy OpenCVE. const cluster = new linode.LkeCluster("my-cluster", { region: "us-central", // Replace with your desired Linode region k8sVersion: "1.21", // Choose a version of Kubernetes supported by LKE tags: ["opencve"], pools: [{ type: "g6-standard-2", // Define the type of node to use count: 3, // Define the number of nodes }], }); // Step 2: Get the kubeconfig from the newly created LKE cluster. const kubeconfig = pulumi.unsecret(cluster.kubeconfig); // Step 3: Use Pulumi's Kubernetes provider to interact with the LKE cluster. const k8sProvider = new kubernetes.Provider("k8s", { kubeconfig: kubeconfig.apply(c => c.rawConfig), }); // Step 4: Define the values for the OpenCVE helm chart. const opencveChartValues = { // Specify OpenCVE-specific values here: // e.g., // service: { // type: "LoadBalancer", // }, // You can refer to the OpenCVE helm chart documentation for all available values. }; // Step 5: Deploy the OpenCVE helm chart on the LKE cluster using the defined chart values. const opencveChart = new kubernetes.helm.v3.Chart("opencve", { chart: "opencve", // The name of the chart version: "1.0.0", // Specify the chart version fetchOpts: { repo: "https://charts.opencve.io", // The URL of the helm repo }, values: opencveChartValues, }, { provider: k8sProvider }); // Export the resulting application's endpoint. // (Note: This assumes OpenCVE is a web application that gets an external IP assigned.) export const opencveEndpoint = opencveChart.getResourceProperty("v1/Service", "opencve", "status").apply(status => { return status.loadBalancer?.ingress[0].ip; });

    Make sure you have Pulumi installed and configured for use with your Linode account. To run this Pulumi program, save the code to a file with a .ts extension, for example, index.ts. You must also configure the Pulumi Linode plugin if you haven't already:

    pulumi plugin install resource linode <version>

    Replace <version> with the version of the Linode plugin compatible with your Pulumi CLI.

    Next, install the necessary NPM packages using:

    npm install @pulumi/pulumi @pulumi/linode @pulumi/kubernetes

    You can then run the program using the Pulumi CLI:

    pulumi up

    Follow the CLI prompts to provision the resources. The pulumi up command will show you a preview of the resources to be created. If you confirm the operation, Pulumi will provision a new Linode Kubernetes cluster and deploy the OpenCVE helm chart to it.

    When the deployment is complete, Pulumi will show you the outputs, which will include the opencveEndpoint. This endpoint will point to the external IP that the LoadBalancer has assigned to the OpenCVE service, giving you access to the deployed application.
