Deploy the snyk-exporter helm chart on Kubernetes

Question

Pulumi · Accepted Answer

To deploy the `snyk-exporter` helm chart on a Kubernetes cluster using Pulumi, we'll use the `Chart` resource from the `@pulumi/kubernetes` package. This resource allows us to deploy Helm charts in a similar manner as we would using the `helm` CLI.

First, we have to define our stack using TypeScript, Pulumi’s programming model, and its libraries. We'll start by importing the necessary Pulumi libraries.

Then, we'll create a new instance of `Chart`, specifying the name of the chart, any custom values we want to provide, and the namespace in which to deploy the chart. Since the `snyk-exporter` helm chart might not be part of the default Helm chart repository, we may need to specify the Helm chart's repository URL.

Here's what the Pulumi program might look like in TypeScript:

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

// Define the namespace where the helm chart will be installed
const namespace = new k8s.core.v1.Namespace("snyk-exporter-ns", {
    metadata: { name: "snyk-exporter" },
});

// Deploy the snyk-exporter helm chart in the created namespace
const snykExporterChart = new k8s.helm.v3.Chart("snyk-exporter", {
    chart: "snyk-exporter",
    version: "1.0.0", // Replace with the actual chart version you wish to deploy
    namespace: namespace.metadata.name,
    // Replace with the actual repository URL that hosts the snyk-exporter helm chart
    fetchOpts: {
        repo: "https://charts.snyk.io",
    },
    // Set any custom values you need for the snyk-exporter chart; see the chart's documentation for available options
    values: {
        /* e.g., replicaCount: 2 */
    },
});

// Export the namespace and URL to access the snyk-exporter service
export const snykExporterNamespace = namespace.metadata.name;
export const snykExporterServiceUrl = pulumi.interpolate`http://snyk-exporter.${namespace.metadata.name}.svc.cluster.local:80`;

```

This program assumes that you have a Kubernetes cluster already set up and configured to work with Pulumi. The program creates a namespace called `snyk-exporter` into which it installs the `snyk-exporter` helm chart. The `fetchOpts` argument is used to provide the repository URL of the helm chart, and the `values` field is where you can pass any custom configurations for the chart. The version specified should match the version of the chart you wish to deploy. Adjust it according to the chart's available versions.

Please ensure the chart name, version, and repository values are correct, as they are placeholders for the purpose of this example. Check the official documentation or repository of the `snyk-exporter` helm chart for the exact details.

Remember, before running this program, you should have completed these steps:

1. Have Pulumi installed and set up.
2. Have access to a Kubernetes cluster and the `kubeconfig` file in place.
3. Optionally, if integrating with a CI/CD system, you would have Pulumi access tokens and other environment configurations set up.

To run this Pulumi program:

1. Save this code into a file named `index.ts`.
2. Run `pulumi up` from the command line in the directory containing your `index.ts`. This will start the deployment process.

The `pulumi up` command will show you a preview of the resources that will be created and prompt you to confirm the deployment. Once confirmed, it will deploy the helm chart to your Kubernetes cluster. After the deployment is completed, Pulumi will output any exported variables, such as the namespace and information to access the deployed snyk-exporter if you've configured it to export this information.

For further customization and configuration of the chart, always refer to the chart-specific documentation or values.yaml file.
