Deploy the internal-ingress helm chart on Linode Kubernetes Engine
TypeScriptTo deploy the
internal-ingress
Helm chart on Linode Kubernetes Engine (LKE), you'll need to use Pulumi with its Kubernetes provider. Helm charts are a way to define, install, and manage Kubernetes applications. Pulumi's Kubernetes provider allows you to deploy Helm charts in a declarative way using infrastructure as code.Below is a program written in TypeScript that outlines the steps needed to deploy a Helm chart on an LKE cluster. The steps included are:
- Setting up the Pulumi program and importing the necessary packages.
- Creating a reference to the LKE cluster where the Helm chart will be deployed.
- Deploying the Helm chart to the LKE cluster.
Before running this code, make sure you have set up your Linode Kubernetes Engine cluster and have the kubeconfig file necessary to interact with your cluster. This kubeconfig file must be correctly set up in your environment to allow Pulumi to interact with your cluster.
Here's the program to deploy the
internal-ingress
Helm chart:import * as pulumi from '@pulumi/pulumi'; import * as k8s from '@pulumi/kubernetes'; // Set up a Kubernetes provider by passing in the kubeconfig for the Linode Kubernetes Engine cluster. const provider = new k8s.Provider("lkeProvider", { kubeconfig: <your-kubeconfig-here>, // Replace with your kubeconfig content or path }); // Deploy the `internal-ingress` Helm chart to the LKE cluster const internalIngressChart = new k8s.helm.v3.Chart("internal-ingress", { chart: "internal-ingress", // If the chart is from a custom repository, you'll need to provide the `repo` property. // For example: // repo: "https://charts.example.com/", // Specify the namespace and any custom values for your chart. // namespace: <namespace-here>, // values: { <your-chart-values-here> }, }, { provider }); // Export the status of the Helm chart deployment export const helmChartStatus = internalIngressChart.status;
In this program:
- Replace
<your-kubeconfig-here>
with the content of your kubeconfig file or the path to the file. This is required for Pulumi to interact with your LKE cluster. - If your
internal-ingress
chart is from a custom Helm repository, specify therepo
URL. - You can specify the namespace where you want to deploy the chart using the
namespace
key. - Use the
values
key to override default chart values. This is where you configure custom values if needed for yourinternal-ingress
Helm chart.
Remember to handle your kubeconfig securely, as it provides access to your Kubernetes cluster.
To execute the Pulumi program:
- Install the required Pulumi packages using npm or yarn.
- Run the
pulumi up
command which will show a preview of the resources that will be deployed. Confirm the operation to proceed with the deployment. - After deployment, the status of the Helm chart will be exported, which can be viewed using
pulumi stack output helmChartStatus
.
This program assumes that you have the
internal-ingress
Helm chart available. If the chart needs to be customized, you'll have to modify thevalues
property based on the chart's configurable options.The reference to the
kubernetes.helm.v3.Chart
class in the Pulumi Registry is used in this code, which is a part of Pulumi's Kubernetes provider and is responsible for managing Helm chart releases.Ensure that you have installed the Pulumi CLI and have configured access to your Linode account where your Kubernetes Engine cluster is running.
