Deploy the sysdig helm chart on Oracle Kubernetes Engine (OKE)

Question

Pulumi · Accepted Answer

To deploy the Sysdig Helm chart on Oracle Kubernetes Engine (OKE), you need to follow these steps:

1. Set up your environment to use Pulumi with Oracle Cloud Infrastructure (OCI).
2. Configure the Kubernetes provider to interact with your OKE cluster.
3. Use the Helm Chart resource from the Pulumi Kubernetes provider to deploy Sysdig.

Below is a program written in TypeScript that demonstrates how to perform these steps using Pulumi.

First, make sure you have the following prerequisites in place:
- Installed Pulumi CLI and set up the Pulumi project.
- Installed and configured OCI CLI with the necessary permissions and credentials to create resources in your compartment and manage OKE.
- An existing OKE cluster where you will deploy the Sysdig Helm chart.

Next, install the Pulumi Kubernetes provider package by running the following command in your terminal:

```bash
npm install @pulumi/kubernetes
```

Now, you can write the Pulumi program to deploy the Sysdig Helm chart. Here's how:

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

// Replace the placeholder values with the details of your Oracle Kubernetes Engine context.
const okeClusterContext = "your-oke-cluster-context-name"; // You can get this from your Kubernetes config file (usually ~/.kube/config)

// Create a Kubernetes provider instance that uses your OKE cluster's context.
const provider = new k8s.Provider("oke-k8s", {
    kubeconfig: pulumi.output({ isSecret: true, value: process.env.KUBECONFIG }).apply(kc => kc!),
    context: okeClusterContext,
});

// Define the Sysdig Helm chart resource. Make sure to replace `sysdig-chart-version` with the desired chart version.
const sysdigChart = new k8s.helm.v3.Chart("sysdig", {
    chart: "sysdig",
    version: "sysdig-chart-version",
    fetchOpts: {
        repo: "https://charts.sysdig.com/",
    },
    // Include any custom values you wish to override here.
    values: {
        sysdig: {
            /* your configuration values here */
        },
    },
}, { provider });

// Export the chart's status URL, which can be used to access your Sysdig dashboard once it's ready.
export const sysdigStatusUrl = pulumi.interpolate`https://app.sysdigcloud.com/#/scanning/anchors`;

```

This Pulumi program does the following:
- Imports the required Pulumi modules.
- Creates a Kubernetes provider which is configured to use your OKE cluster context. This enables Pulumi to manage resources in your OKE cluster.
- Defines a Helm chart resource for the Sysdig Helm chart, specifying the chart name, version, and the chart repository URL. It also applies any custom values to configure Sysdig that you include in the `values` property. You'll need to replace `sysdig-chart-version` with the actual version of the Sysdig Helm chart you want to deploy.
- Exports a Sysdig status URL, which you can visit in your web browser to access the Sysdig dashboard once it's ready.

Please ensure you replace the placeholder values with actual values from your setup. Additionally, you'll need to run `pulumi up` to deploy the resources defined in this program. This will prompt Pulumi to perform the necessary actions to provision the Helm chart on your OKE cluster.

Ensure to review [Sysdig's official Helm chart documentation](https://github.com/sysdiglabs/charts) for more details on the available configuration options and best practices for deploying the chart.
