  • Visibility: Kubecost provides a centralized dashboard for monitoring your cloud usage. With real-time visibility into your infrastructure, you can identify cost anomalies and quickly take action.

How Kubecost works? 

Kubecost works by collecting resource usage data from your Kubernetes cluster and mapping that usage to costs. Kubecost uses a combination of metrics from Prometheus, Kubernetes API data, and cost data from your cloud provider to provide accurate cost allocation and optimization insights.

Let’s take a closer look at each of these components:

1. Cost Model

The Cost Model is the core of Kubecost, providing real-time visibility into the cost of your Kubernetes resources. The Cost Model is a data pipeline that collects resource usage data from Kubernetes and cloud providers and calculates the cost of each resource. It supports multiple cloud providers and integrates with Prometheus, the popular open-source monitoring solution, to collect usage data.

2. Cost Explorer

The Cost Explorer is the user interface for Kubecost, providing a graphical view of your cloud costs and usage. The Cost Explorer provides an overview of your cloud costs and allows you to drill down into specific resources to see usage and costs over time. You can also compare costs across different cloud providers and see how changes to your infrastructure impact costs.

3. Allocation Engine

The Allocation Engine is a feature of Kubecost that allows you to allocate costs to different teams or projects in your organization. The Allocation Engine automatically assigns costs to teams based on resource usage and allows you to customize allocation rules based on your organization’s needs. This feature makes it easy to track costs across teams and projects and ensures that each team is responsible for their own cloud costs.

4. Recommendations Engine

The Recommendations Engine is a feature of Kubecost that provides recommendations for cost optimization and resource allocation. The engine analyzes your cloud usage data and provides recommendations for optimizing resource allocation, reducing costs, and improving reliability. The Recommendations Engine helps you identify areas of your infrastructure that are over-provisioned or underutilized and provides actionable recommendations to help you optimize your resources.

5. Budget Alerts

Kubecost provides Budget Alerts, a feature that alerts you when you reach predefined budget thresholds. You can set up alerts to notify you when you’re approaching a budget limit, when you exceed a budget limit, or when usage spikes unexpectedly. Budget Alerts can be configured to send notifications via email or Slack, ensuring that you’re always aware of your cloud costs.

In addition to these components, Kubecost also includes several other features and integrations that make it a powerful cost management platform for Kubernetes. These features include a Grafana dashboard for advanced data visualization, integrations with AWS, GCP, and Azure, and support for multiple currencies and billing periods. Overall, Kubecost is a comprehensive solution for managing cloud costs and optimizing resource allocation in Kubernetes.

Getting started with Kubecost

To get started with Kubecost, follow these steps:

Install the Kubecost Helm chart

Kubecost can be installed using Helm, a package manager for Kubernetes. The Kubecost Helm chart includes all the components you need to get started with cost allocation and optimization.

Installing Kubecost using Helm charts is a simple process that can be completed in just a few steps. Here’s a step-by-step guide on how to install Kubecost using Helm charts:

1. Install Helm

Before you can install Kubecost using Helm, you need to have the Helm client installed on your machine. You can download and install the Helm client from the Helm website.

2. Add the Kubecost Helm repository

Next, you need to add the Kubecost Helm repository to Helm. You can do this by running the following command:

helm repo add kubecost https://kubecost.github.io/cost-analyzer/


This command adds the Kubecost Helm repository to your Helm configuration.

3. Install Kubecost using Helm

Once you’ve added the Kubecost Helm repository, you can install Kubecost using the following command:


helm install kubecost \
  --repo https://kubecost.github.io/cost-analyzer cost-analyzer \
  --namespace kubecost --create-namespace \
  --version 1.101.3 \
  --set kubecostModel.cloudCost.enabled=true \
  --set kubecostModel.etlCloudUsage=false


This command installs the Kubecost cost-analyzer chart in the kubecost namespace. The –create-namespace flag creates the kubecost namespace if it doesn’t already exist.

4. Verify the installation

After the installation is complete, you can verify that Kubecost is running by checking the status of the Kubecost pods:

kubectl get pods -n kubecost

This command should return a list of pods running in the kubecost namespace.

5. Access the Kubecost dashboard

Finally, you can access the Kubecost dashboard by forwarding the port for the Kubecost service to your local machine. You can do this using the following command:

kubectl port-forward service/kubecost-cost-analyzer 9090 -n kubecost

This command forwards port 9090 on your local machine to port 9090 on the Kubecost service. You can then access the Kubecost dashboard by navigating to http://localhost:9090 in your web browser.

And that’s it! You now have Kubecost installed and running in your Kubernetes cluster. You can use the Kubecost dashboard to monitor your cloud usage and optimize your infrastructure for cost savings.
