Deploy the opencve helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the OpenCVE Helm chart on an OpenShift cluster using Pulumi, you'll need to first ensure that you have an OpenShift cluster running and that you can connect to it with the `kubectl` or `oc` command-line tool. OpenShift is Kubernetes with additional enterprise features, and Helm charts are packages that help you deploy applications on Kubernetes.

Let's break down the steps you would need to follow to accomplish this using Pulumi and the `kubernetes` package:

1. Set up the Pulumi project and import necessary packages.
2. Define a Kubernetes provider that points to your OpenShift cluster.
3. Use Helm chart resource to deploy OpenCVE to the OpenShift cluster.

Here's a Pulumi program in TypeScript that demonstrates how you can deploy the OpenCVE Helm chart on an OpenShift cluster:

```typescript
import * as k8s from "@pulumi/kubernetes";

// Step 1: Set up the Kubernetes provider to connect to your OpenShift cluster.
// Make sure you have your OpenShift cluster's `kubeconfig` file correctly configured
// in your environment or provide the `kubeconfig` directly to the provider instance.
const provider = new k8s.Provider("openshift", {
  // Assuming you have KUBECONFIG environment variable set, or you can directly pass in the kubeconfig content.
  kubeconfig: process.env.KUBECONFIG,
});

// Step 2: Define the Helm Chart for OpenCVE.
// This example assumes the OpenCVE chart is available in a Helm repo and you know the chart name.
// If it's not in a public repository, add the `repo` property with the correct Helm repository URL.
const openCVEChart = new k8s.helm.v3.Chart("opencve", {
  chart: "opencve", // Replace with the correct Helm chart name if it's different.
  // Add any values you wish to override in the `values` property.
  values: {
    // ... your OpenCVE specific Helm values ...
  },
  // If required, specify the namespace where the chart should be installed.
  // If no namespace is provided, it will be installed in the 'default' namespace.
  namespace: "opencve-namespace",
}, { provider });

// Export any necessary resources, such as the URL to access the OpenCVE interface.
export const openCVEUrl = openCVEChart.getResourceProperty(
  "v1/Service", "opencve-namespace", "opencve", "status"
).apply(status => status.loadBalancer.ingress[0].hostname);
```

In this program, we start by creating a Pulumi provider that uses your existing OpenShift kubeconfig to establish communication with your OpenShift cluster. This provider is used for all Kubernetes resources defined in the program.

Next, we define the Helm chart for OpenCVE. We need to provide the chart name and optionally, any specific configuration needed to deploy OpenCVE in your OpenShift cluster via the `values` property. We also specify the `namespace` where the OpenCVE chart should be deployed.

Finally, we've added an export statement to output the URL to access OpenCVE once deployed, assuming it creates a service of type LoadBalancer or something similar that we can extract a hostname from.

To apply this Pulumi program, follow these steps:

1. Ensure you have Pulumi CLI installed and configured with access to your cloud provider.
2. Initialize a new Pulumi project or use an existing one.
3. Place the TypeScript code shared above in a file named `index.ts`.
4. Run `pulumi up` to preview and deploy the resources.

Make sure to adjust the `chart`, and `values` as needed for your specific case, and make sure you have permissions to deploy resources on the OpenShift cluster.
