Deploy the kloudlite-autoscalers helm chart on Google Kubernetes Engine (GKE)
TypeScriptTo deploy a Helm chart to a Google Kubernetes Engine (GKE) cluster using Pulumi, you'll need to follow these steps:
- Set up a GKE cluster.
- Install the Helm chart on the GKE cluster.
To get started, make sure you have Pulumi CLI installed and you're authenticated with Google Cloud.
Setting up a GKE Cluster
First, you'll need to create a GKE cluster where your Helm chart will be deployed. This involves defining a
gcp.container.Cluster
resource, which represents a GKE cluster.Installing the Helm Chart
Once the cluster is available, you'll deploy the Helm chart using the
kubernetes.helm.v3.Chart
resource. This Pulumi resource allows you to install Helm charts in a Kubernetes cluster.Below, there's a Pulumi program written in TypeScript that sets up a GKE cluster and installs a Helm chart on it. The name of the Helm chart,
kloudlite-autoscalers
, suggests that it includes some autoscaling capabilities.import * as pulumi from '@pulumi/pulumi'; import * as gcp from '@pulumi/gcp'; import * as k8s from '@pulumi/kubernetes'; // Configuration for the GKE cluster const name = "kloudlite-cluster"; const machineType = "n1-standard-1"; const initialNodeCount = 2; const location = "us-central1-c"; // Change according to your preferred GCP region // Create a GKE cluster const cluster = new gcp.container.Cluster(name, { initialNodeCount: initialNodeCount, nodeVersion: "latest", minMasterVersion: "latest", location: location, nodeConfig: { machineType: machineType, oauthScopes: [ "https://www.googleapis.com/auth/compute", "https://www.googleapis.com/auth/devstorage.read_only", "https://www.googleapis.com/auth/logging.write", "https://www.googleapis.com/auth/monitoring" ], }, }); // Export the Cluster name export const clusterName = cluster.name; // Kubernetes provider to connect to the GKE cluster const k8sProvider = new k8s.Provider(name, { kubeconfig: cluster.kubeConfigRaw, }); // Deploy the kloudlite-autoscalers Helm chart to the GKE cluster const helmChart = new k8s.helm.v3.Chart("kloudlite-autoscalers-chart", { // Replace these parameters with the ones that are applicable for your Helm chart repo: "<HELM_CHART_REPOSITORY>", chart: "kloudlite-autoscalers", version: "<HELM_CHART_VERSION>", namespace: "default", // Specify the namespace if it's different than default }, { provider: k8sProvider }); // Export the Helm chart status export const helmChartStatus = helmChart.status;
Replace
<HELM_CHART_REPOSITORY>
and<HELM_CHART_VERSION>
with the correct repository URL and chart version for thekloudlite-autoscalers
Helm chart. If you have downloaded the Helm chart locally, you can specify the local directory path with apath
property instead ofrepo
,chart
, andversion
.This program does the following:
- Defines a new GKE cluster with the specified name, machine type, and node count.
- Exports the cluster name.
- Creates a Kubernetes provider that uses the kubeconfig from the newly created GKE cluster.
- Deploys the
kloudlite-autoscalers
Helm chart to the GKE cluster using the Kubernetes provider.
To run this program, save it to a file, say
index.ts
, and then runpulumi up
from the command line in the same directory.If you're new to Pulumi and TypeScript, here are some resources that you may find useful:
The Pulumi Registry Page for GKE clusters has more details on the properties that can be set for a GKE cluster. Similarly, details for the Helm chart resource can be found on the Pulumi Registry Page for Kubernetes Helm charts.
