Deploy the newrelic-operator helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `newrelic-operator` Helm chart on a Kubernetes cluster (like one from Linode Kubernetes Engine), you would typically follow these steps:

1. Set up the necessary Pulumi stack and select the Kubernetes provider connected to your Linode cluster.
2. Use the `kubernetes.helm.v3.Chart` resource to deploy the `newrelic-operator` chart from the Helm repository.

Below I will provide a commented code block, which uses TypeScript to describe the deployment of the New Relic Operator using a Helm chart onto a Kubernetes cluster in Pulumi:

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

// Create a new instance of the Kubernetes Helm Chart class, which represents a Helm chart in a repo.
const newrelicOperator = new k8s.helm.v3.Chart("newrelic-operator", {
    // Define the repository and the chart we want to use
    repo: "newrelic",
    chart: "newrelic-operator",
    // The following version and values parts are placeholders.
    // You may need to change these depending on your specific requirements and the chart version compatibility.
    version: "1.2.3", // <--- Replace with the actual chart version you wish to deploy
    values: {
        // Provide any custom values required by the New Relic Operator Helm chart
        clusterName: "linode-cluster", // <--- Replace with the name of your Linode Kubernetes cluster
        licenseKey: "yourNewRelicLicenseKey", // <--- Replace with your New Relic license key
        // ... add other custom values as per the New Relic Operator Helm chart documentation
    },
    // Select the appropriate namespace where you want the operator to be deployed
    namespace: "new-relic", // <--- Replace with the target namespace (create it if it doesn't exist)
});

// Export any desired properties, like the Helm release status or resources.
export const releaseStatus = newrelicOperator.status;
```

This code block defines a single Pulumi resource, which will instruct Pulumi to install the specified version of the `newrelic-operator` Helm chart with the given values when applied to the Linode Kubernetes Engine cluster. Make sure you configure Pulumi to connect to the correct Kubernetes context corresponding to your Linode cluster. You will need to replace `version`, `clusterName`, `licenseKey`, and `namespace` with appropriate values for your environment.

Ensure you have your Kubernetes configuration set so that Pulumi can connect to your Linode Kubernetes Engine cluster. You can typically do this by obtaining your kubeconfig file from Linode and setting the `KUBECONFIG` environment variable.

Before running this program, you should have Pulumi installed and set up for TS/JS projects, and you should have initialized a Pulumi project with `pulumi new`.

To apply the Pulumi program:
1. Navigate to the folder containing your Pulumi program.
2. Run `pulumi up` in the command line.
3. Review the execution plan from Pulumi to ensure it matches your expectations.
4. Confirm the changes to start the deployment.

Once the deployment is successful, Pulumi will output the status of the Helm release as well as any other exported properties.
