Deploy the zinc helm chart on Linode Kubernetes Engine
TypeScriptTo accomplish the deployment of a Helm chart to a Kubernetes cluster on Linode, you'll take the following steps:
- Set up a Kubernetes cluster on Linode using the Linode Kubernetes Engine (LKE).
- Deploy the Zinc Helm chart to the Kubernetes cluster.
For the first step, we won't directly use Pulumi as Linode is not yet one of the cloud providers supported natively by Pulumi. However, you can use the Linode CLI or the Linode Cloud Manager to set up your Kubernetes cluster.
Once you have a Kubernetes cluster running on Linode, you can use Pulumi with the Pulumi Kubernetes provider to deploy your Helm chart to your cluster.
Let's first assume you have set up a Linode Kubernetes cluster and have the
kubeconfig
file that allows you to interact with your cluster.From here, we will use Pulumi to deploy the Zinc Helm chart. We'll begin by writing a Pulumi program in TypeScript to achieve this. Make sure you have the following prerequisites ready:
- Install Node.js and npm on your local machine (https://nodejs.org/).
- Install Pulumi CLI (https://www.pulumi.com/docs/get-started/install/).
- Have your
kubeconfig
file obtained from Linode. - Know the name of the Helm chart you want to deploy or have it hosted on a chart repository that Pulumi can access.
Here is your Pulumi TypeScript program to deploy the Zinc Helm chart to your LKE cluster:
import * as k8s from "@pulumi/kubernetes"; // Create an instance of the Kubernetes provider using the kubeconfig from Linode. const k8sProvider = new k8s.Provider("lkeK8sProvider", { kubeconfig: "<your kubeconfig string here>", }); // Provide the details of the Helm chart you wish to deploy. // In this example, we're assuming 'zinc' is the name of the chart, // and it's hosted on a reachable Helm repository. const zincHelmChart = new k8s.helm.v3.Chart("zinc", { chart: "zinc", version: "<version of the chart>", // specify the chart version if needed // Add the repository here if it's not a stable chart that's already known. // Uncomment and fill the line below if needed. // repositoryOpts: { repo: "http://<helm-chart-repository>" }, // Set the values for the Helm chart as per your requirements. values: { // ... key-value pairs matching the expected values of the Helm chart }, }, { provider: k8sProvider }); // Export the endpoint of the Zinc deployment if it includes any public services. export const zincEndpoint = zincHelmChart.getResourceProperty("v1/Service", "<zinc service name>", "status").apply(status => status.loadBalancer.ingress[0].ip);
Replace
<your kubeconfig string here>
with the actual content of your kubeconfig file, replace<version of the chart>
with the specific version of the chart you want to deploy, and provide the required Helm chart values inside thevalues
field. If the Zinc chart exposes a service and you want to obtain its endpoint, make sure to replace<zinc service name>
with the actual service name defined in your Zinc chart.To execute the Pulumi program, follow these steps:
- Initialize a new Pulumi project in a directory of your choice.
- Install the necessary dependencies using npm:
npm install @pulumi/kubernetes
- Place the TypeScript code into a file named
index.ts
. - Run
pulumi up
to preview and deploy the changes.
Pulumi will communicate with your Linode Kubernetes cluster and deploy the specified Helm chart to it. If the deployment includes any public services, the exported endpoint will be shown at the end of the deployment process.
Remember to regularly check the official Pulumi documentation and Linode's documentation to stay updated on their services and integration capabilities.
