Deploy the aws-node-termination-handler-2 helm chart on Google Kubernetes Engine (GKE)
TypeScriptTo deploy the
aws-node-termination-handler-2
Helm chart on Google Kubernetes Engine (GKE), we will follow these steps:- Set up a GKE cluster: We'll need a Kubernetes cluster running on Google Cloud GKE to deploy our Helm chart.
- Install the Pulumi Helm provider: This provider allows us to work with Helm charts in Pulumi.
- Deploy the Helm chart: We will write a Pulumi program to deploy the
aws-node-termination-handler-2
chart to our GKE cluster.
Step 1: Set up a GKE cluster
Before deploying the Helm chart, you need a GKE cluster. This can be provisioned using Pulumi's GCP provider. You'll need to configure your Pulumi GCP settings with appropriate credentials to manage resources in your Google Cloud account.
Step 2: Install Pulumi Helm provider
The Pulumi Helm provider is a plugin that needs to be installed in your environment where Pulumi runs. It is typically installed automatically when you first run a Pulumi program that requires it, or you can manually install it with the
pulumi plugin install
command.Step 3: Deploy the Helm chart
In your Pulumi TypeScript program, you'll use the
Chart
resource from the Pulumi Kubernetes provider to deploy theaws-node-termination-handler-2
chart. This resource is an abstraction that models Helm chart deployment as a Pulumi resource.Here's a Pulumi program in TypeScript that carries out the above steps:
import * as pulumi from "@pulumi/pulumi"; import * as gcp from "@pulumi/gcp"; import * as k8s from "@pulumi/kubernetes"; // Step 1: Set up a GKE cluster const cluster = new gcp.container.Cluster("gke-cluster", { initialNodeCount: 2, minMasterVersion: "latest", // Specify the version of GKE cluster, or use 'latest' for the latest version nodeVersion: "latest", nodeConfig: { machineType: "n1-standard-1", // Adjust the machine type as needed }, }); // Export the Cluster name export const clusterName = cluster.name; // Export the Kubeconfig to access the GKE cluster export const kubeconfig = pulumi. all([cluster.name, cluster.endpoint, cluster.masterAuth]). apply(([name, endpoint, masterAuth]) => { const context = `${gcp.config.project}_${gcp.config.zone}_${name}`; return `apiVersion: v1 clusters: - cluster: certificate-authority-data: ${masterAuth.clusterCaCertificate} server: https://${endpoint} name: ${context} contexts: - context: cluster: ${context} user: ${context} name: ${context} current-context: ${context} kind: Config preferences: {} users: - name: ${context} user: auth-provider: config: cmd-args: config config-helper --format=json cmd-path: gcloud expiry-key: '{.credential.token_expiry}' token-key: '{.credential.access_token}' name: gcp `; }); // Step 3: Deploy the Helm chart const nodeTerminationHandler = new k8s.helm.v3.Chart("aws-node-termination-handler", { chart: "aws-node-termination-handler-2", version: "0.9.0", // Specify the chart version, change it to the available chart version if needed fetchOpts: { repo: "http://<helm-chart-repository-url>", // Replace with the repository URL that hosts the aws-node-termination-handler chart }, }, { provider: new k8s.Provider("gkeK8s", { kubeconfig }) }); // Export the status of the Helm chart deployment export const nodeTerminationHandlerStatus = nodeTerminationHandler.status;
This code does the following:
- Creates a GKE cluster with the specified number of nodes and machine type.
- Generates a kubeconfig file needed to interact with the GKE cluster.
- Sets up a Helm release for the
aws-node-termination-handler-2
chart on the GKE cluster using the Helm provider for Kubernetes.
Make sure to replace
<helm-chart-repository-url>
with the correct URL to where theaws-node-termination-handler-2
chart is hosted.Keep in mind that the exact configurations (like
machineType
,minMasterVersion
, chartversion
, andchart
name) may vary based on your specific requirements and the availability of GKE and Helm chart versions.To run this program:
- Ensure you have Pulumi installed and configured for TypeScript.
- Create a new directory for your project and initialize a new Pulumi project with
pulumi new typescript
. - Replace the contents of
index.ts
with the code provided above. - Run
pulumi up
to create the GKE cluster and deploy the Helm chart.
Remember that running this program on your cloud provider may incur charges. Always check the associated costs and manage resources accordingly.
