Deploy the aliyun-exporter helm chart on AWS EKS
TypeScriptDeploying the
aliyun-exporter
Helm chart on an AWS EKS (Elastic Kubernetes Service) cluster involves several steps: setting up an EKS cluster, installing the Helm CLI, and deploying the chart. Pulumi is a modern infrastructure as code platform that can greatly simplify this process by codifying all the required steps in TypeScript.Below, I present a Pulumi program that creates an EKS cluster on AWS and then deploys the
aliyun-exporter
helm chart into that cluster.Setting Up AWS EKS Cluster
First, you need to create an EKS cluster. An EKS cluster provides the Kubernetes control plane. Pulumi provides a high-level library to create and manage EKS clusters easily with the
eks
package.Deploying the Helm Chart
After the cluster is up and running, you will deploy the
aliyun-exporter
Helm chart to the cluster. Pulumi'skubernetes
package can install Helm charts directly onto your EKS cluster.Program Explanation
-
EKS Cluster Creation: The
eks.Cluster
resource is used to create an EKS cluster. The specifics, such as the instance type for worker nodes, name of the cluster, and desired capacity, are configurable. Here, we keep default values for simplicity. -
Helm Chart Deployment: After the EKS cluster is provisioned, the
kubernetes.helm.v3.Chart
resource is used to install thealiyun-exporter
Helm chart from its repository. You may provide any required configuration through thevalues
argument.
Pulumi Program in TypeScript
import * as eks from "@pulumi/eks"; import * as aws from "@pulumi/aws"; import * as k8s from "@pulumi/kubernetes"; // Create an EKS cluster. const cluster = new eks.Cluster("my-cluster", {}); // Export the cluster's kubeconfig. export const kubeconfig = cluster.kubeconfig; // Install the aliyun-exporter Helm chart into the cluster. const aliyunExporterChart = new k8s.helm.v3.Chart("aliyun-exporter", { chart: "aliyun-exporter", version: "0.3.1", // Specify the version you'd like to deploy fetchOpts: { repo: "https://charts.kubeops.gardener.cn/", // Helm repository that contains the chart. }, }, { provider: new k8s.Provider("k8s-provider", { kubeconfig: cluster.kubeconfig }) }); // Reference: eks.Cluster - https://www.pulumi.com/registry/packages/eks/api-docs/cluster/ // Reference: kubernetes.helm.v3.Chart - https://www.pulumi.com/registry/packages/kubernetes/api-docs/helm.sh/v3/chart/
Next Steps
- Set up Pulumi: Install the Pulumi CLI and set up your AWS credentials.
- Create a Pulumi Project: Create a new Pulumi project and copy the code into
index.ts
. - Deploy: Run
pulumi up
to deploy your EKS cluster and the Helm chart. - Use Your Cluster: Once the deployment is complete, use the exported
kubeconfig
to interact with your Cluster usingkubectl
.
Keep in mind that you need to have Helm installed locally and configured with your Kubernetes cluster to deploy Helm charts, but Pulumi abstracts this by directly interfacing with the Helm CLI.
This program assumes that the
aliyun-exporter
Helm chart is compatible with your version of Kubernetes on EKS and is available in the specified Helm repository. If the chart has additional dependencies or configurations, you may need to modify thevalues
parameter accordingly.-
