If you've ever dabbled with Infrastructure as Code, or it's something you've been interested in doing, we think you're going to like this one... đ„
Kubecost can now be deployed and configured on Amazon EKS using AWS Cloud Development Kit (CDK) as an EKS Blueprint!
What are Amazon EKS Blueprints?
EKS Blueprints are a way to abstract cloud infrastructure complexity away from software developers. Blueprints allow developers to deploy containerized workloads using tools and languages that they are already familiar with. With the help of EKS Blueprints, teams can consolidate tools and best practices into a single central platform that can then be used across their organization.
A Blueprint is typically composed of multiple AWS or open source products and services, including services for running containers, CI/CD pipelines, capturing logs/metrics, and security enforcement. Blueprints can help package these tools into a cohesive whole and make them available to development teams as a service.
How Kubecost helps
Given the sheer scale and complexity of Kubernetes environments, tracking cloud spend can quickly become problematic. For any organization running services on Kubernetes, having a way to continuously monitor and optimize costs is an important best practice to introduce and automate early on.
Kubecost automatically provides cost visibility, savings optimizations, and ongoing governance for EKS deployments, and presents a unified view of these costs along with those of all other Kubernetes infrastructure. With Kubecost, users reduce the operational burden of managing multiple cost views and manually tracking spend for each of their services.
The Kubecost EKS Blueprint AddOn allows teams to automatically provision and maintain Kubecost across multiple clusters, making it part of the internal development platform for the enterprise. The AddOn can be deployed and configured as part of your EKS Blueprint using AWS CDK (Cloud Development Kit), with just a few lines of TypeScript or JavaScript code!
About the Kubecost EKS Blueprint AddOn
You can use the EKS Blueprint Kubecost AddOn to:
Install Kubecost, along with its dependencies Prometheus, Grafana, and kube-state-metrics in the kubecost namespace from the official Kubecost Helm chart.
Configure a specific Kubecost version.
Set custom values for the values.yaml file.
All using CDK and TypeScript or JavaScript.
How to use the AddOn
Create a CDK project
To get started, youâll first need to install appropriate versions of AWS CLI, AWS CDK, and then bootstrap a CDK project. Follow the EKS Blueprint Quick Start documentation to go through those steps.
Once youâve bootstrapped the project, go ahead and install the eks-blueprints library, which will allow you to use all the EKS Blueprint magic.
$ npm install @aws-quickstart/eks-blueprints
Install Kubecost EKS Blueprints AddOn
Install the Kubecost library in your projectâs working directory:
$ npm install @kubecost/kubecost-eks-blueprints-addon
Write some TypeScript code đ©âđ»
You'll notice that running the bootstrap command created some files and folders within your working directory. We'll create a blueprint with the Kubecost AddOn, and then apply it to the cluster.
Note that id is the cluster id. You have two options: either use an existing cluster ID in that region, which will install Kubecost on an existing cluster. Alternatively, give it a new id, which will provision a brand new cluster under the associated AWS account in that region.
Replace the contents of bin/.ts (where your-main-file by default is the name of the root project directory) with the following:
import "source-map-support/register";
import * as cdk from "aws-cdk-lib";
import * as blueprints from "@aws-quickstart/eks-blueprints";
import { KubecostAddOn } from "@kubecost/kubecost-eks-blueprints-addon";
const app = new cdk.App();
const addOn = new KubecostAddOn();
const blueprint = blueprints.EksBlueprint.builder()
.addOns(addOn)
.build(app, "my-stack-name");
Deploy and apply the blueprint using the following command:
$ cdk deploy
Give it some time... and there we are! Once youâve deployed Kubecost this way, youâll be able to view the dashboards using kubectl port-forward command.
$ kubectl port-forward --namespace kubecost deployment/cost-analyzer 9090
Once the Blueprint is set up, it can be deployed in the same configuration across multiple regions and accounts, making sure that all of your clusters are uniform and consistently running Kubecost. The recommended approach for day-two operations is Git-driven pipelines.
Try it yourself!
