Deploy the route53-kubernetes helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy the `route53-kubernetes` Helm chart on Linode Kubernetes Engine (LKE) using Pulumi, you will need to follow these steps:

1. **Set up the Linode Kubernetes Engine**: First, you have to create a Kubernetes cluster using the Linode platform. Unfortunately, as of my knowledge cutoff in 2023, Pulumi does not have a dedicated Linode provider. You would need to create and manage the Kubernetes cluster directly from Linode. Once you have the cluster, make sure you have `kubectl` configured locally to communicate with your LKE cluster.

2. **Manage Kubernetes Resources with Pulumi**: With the Kubernetes cluster in place, you can manage Kubernetes resources, including the deployment of Helm charts, using Pulumi’s Kubernetes provider. The Kubernetes provider can manage your Kubernetes resources by communicating with the cluster's API server.

3. **Helm Chart for Route53**: The `route53-kubernetes` Helm chart will synchronize a Kubernetes cluster with an AWS Route 53 hosted zone, creating DNS records for your Kubernetes services and ingresses.

Below is a TypeScript program using Pulumi to deploy a Helm chart to a Kubernetes cluster. This assumes that you have the `route53-kubernetes` Helm chart available in a Helm repository and the necessary AWS credentials to manage Route 53 are accessible to the `route53-kubernetes` service within your Kubernetes cluster.

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

// Make sure to have your KUBECONFIG environment variable set to the config file
// that points to your Linode Kubernetes Engine cluster when running this Pulumi program.

// Create a Helm chart instance for route53-kubernetes.
const route53HelmChart = new k8s.helm.v3.Chart("route53-kubernetes", {
    chart: "route53-kubernetes",
    version: "1.0.0", // Replace with the actual version that you are intending to deploy.
    // Helm repository where `route53-kubernetes` is hosted,
    // for example: https://charts.example.com/
    repositoryOpts: {
        repo: "https://myhelmrepo.example.com/",
    },
    // Values for the Helm chart.
    // Make sure to configure the values in accordance with the route53-kubernetes documentation.
    values: {
        // Example values - these are placeholders and should be replaced with actual ones.
        aws: {
            accessKeyID: "YOUR_ACCESS_KEY_ID",
            secretAccessKey: "YOUR_SECRET_ACCESS_KEY",
            region: "us-east-1",
            zoneType: "public",
        },
        domainFilters: ["example.com"], // Replace with the domain you want to manage with Route 53.
        // Additional values required for the chart can be specified here.
    },
    // The namespace to deploy the Helm chart into. 
    namespace: "default",
});

// Export the name of the chart resource
export const chartName = route53HelmChart.id;
```

Remember to replace placeholder values with the actual values that are appropriate for your environment, including the version of the Helm chart, repository URL, AWS credentials, and domain configuration.

Make sure to apply the `route53-kubernetes` Helm chart according to your AWS Route 53 hosted zone configuration and security practices, including Kubernetes RBAC and AWS IAM roles where necessary.

To run this Pulumi program, execute `pulumi up` command in the same directory, which will apply changes to your Kubernetes cluster. Ensure that all necessary Pulumi setup has been done and you have selected the appropriate Pulumi stack.

Please note that this program assumes the `kubeconfig` file is correctly configured on your local machine. If you're not familiar with how to connect `kubectl` to your LKE cluster, please refer to [Linode's official documentation](https://www.linode.com/docs/kubernetes/).
