Deploy the bytesafe-ce helm chart on Linode Kubernetes Engine

Question

Pulumi · Accepted Answer

To deploy a Helm chart on a Linode Kubernetes Engine (LKE) cluster using Pulumi, you'll be using Pulumi's Kubernetes provider to create a Chart resource. The following program demonstrates how to accomplish this using TypeScript. Before we dive into the code, here's what you need to know:

Kubernetes Cluster: The program assumes that you've already set up an LKE cluster and configured kubectl to communicate with it.
Helm Chart: Helm charts are packages of pre-configured Kubernetes resources. In this case, we'll be deploying bytesafe-ce, assuming it's available in a public chart repository.
Pulumi Kubernetes Provider: This provider allows Pulumi to interact with Kubernetes, enabling the management of Kubernetes resources.

Here is a step-by-step Pulumi TypeScript program to deploy the bytesafe-ce Helm chart onto an LKE cluster:

import * as k8s from '@pulumi/kubernetes';

// Create a Kubernetes provider instance using the current context of kubectl which is configured for Linode Kubernetes Engine.
const provider = new k8s.Provider('lke-provider', { kubeconfig: '<your-kubeconfig-here>' });

// Deploy the bytesafe-ce helm chart using the kubernetes provider.
const chart = new k8s.helm.v3.Chart('bytesafe-ce', {
    chart: 'bytesafe-ce',
    // The repository where the helm chart is stored. Replace with the actual chart repo URL.
    fetchOpts: {
        repo: 'https://charts.bytesafe.dev/',
    },
    // Specify the namespace to deploy into, if needed. Default is 'default'.
    namespace: 'default', // Change this if the chart should be deployed in a different namespace.
    // Specify any custom values you want to pass to the helm chart.
    values: {
        // Custom values to configure bytesafe-ce. Replace with actual configuration values.
    },
}, { provider: provider });

// Export the base URL for the deployed bytesafe-ce instance
export const bytesafeBaseUrl = chart.getResourceProperty('v1/Service', 'bytesafe-ce', 'status').apply(status => {
    // Assuming the service type is LoadBalancer and it generates an external IP/hostname.
    // This might need to be adjusted depending on the actual service and ingress configuration of bytesafe-ce.
    return status.loadBalancer.ingress[0].hostname || status.loadBalancer.ingress[0].ip;
});

In this program:

Replace '<your-kubeconfig-here>' with the actual kubeconfig obtained from your Linode dashboard or through your Linode Kubernetes Engine setup.
Replace the repo property with the specific repository URL where the bytesafe-ce chart is hosted if it's different from the one provided.

This program creates a new Helm chart resource defined by the bytesafe-ce chart in the specified repository and installs it in the LKE cluster. It's assuming that the Helm chart exposes a service of type LoadBalancer, which it uses to export the base URL of the bytesafe-ce service.

Please replace the kubeconfig with the path to your kubeconfig file or the kubeconfig content itself to establish the connection to your Linode Kubernetes cluster.

After you've updated the kubeconfig and any values specific to the bytesafe-ce chart, you can run this Pulumi program with the usual Pulumi workflow commands:

pulumi up to preview and deploy changes.
Review the preview and select yes to perform the actual deployment.
After the deployment finishes, the output will show the base URL for the deployed bytesafe-ce instance if everything was set up correctly.

Remember to have Pulumi CLI installed and logged in to your Pulumi account where the Pulumi configuration files (Pulumi.yaml and Pulumi.<stack>.yaml) are located in the same folder as the TypeScript file.

Keep in mind that the actual deployment process and resources created, such as the service and ingress paths, may vary based on the specific configurations of the helm chart you are deploying. Adjust the Pulumi program as necessary to match the configuration needs of the bytesafe-ce chart and your LKE setup.
