+# Kubecost with AWS Cloud Billing Integration
+
+This pattern demostrates how to install and configure Kubecost with AWS CUR report.
+The terraform code was created following the official Kubecost documentation for [aws cloud billing integration](https://docs.kubecost.com/install-and-configure/install/cloud-integration/aws-cloud-integrations).
+
+## Prerequisites
+
+You need a valid Kubecost token. To generate one, follow the instructions [here](https://www.kubecost.com/install#show-instructions).
+
+
+# Deploy
+```
+terraform init
+terraform apply -target="module.vpc" -auto-approve
+terraform apply -target="module.eks" -auto-approve
+terraform apply -auto-approve --var="kubecost_token=<your-kubecost-token>"
+```
+
+Once all of the resources have successfully been provisioned, the following command can be used to update the `kubeconfig` on your local machine and allow you to interact with your EKS Cluster using `kubectl`.
+
+```
+ aws eks --region <REGION> update-kubeconfig --name <CLUSTER_NAME>
+```
+
+This command will create a S3 bucket with prefix `kubecost-` and a Cost and Usage Report (CUR). Within 24h The CUR will generate a CloudFormation teamplate file called `crawler-cfn.yml` in the S3 bucket. Once that file is generated, navigate to:
+
+```
+cd run-me-in-24h/
+```
+To download and apply the CloudFormation template, run:
+```
+terraform init
+terraform apply --auto-approve
+```
+
+## Kubecost UI
+To access the Kubecost UI run:
+```
+echo http://$(kubectl -n kubecost get svc cost-analyzer-cost-analyzer -o jsonpath='{.status.loadBalancer.ingress[0].hostname}'):9090/
+```
+and navigate to the output URL.
+
+Navigate to Settings -> Diagnostics -> View Full Diagnostics
+
+Expected result:

+
+> [!NOTE] 
+> Spot Data Feed is included in Savings Plan, Reserved Instance, and Out-Of-Cluster.
+
+## Destroy
+First destroy the CloudFormation template:
+```
+cd run-me-in-24h/
+terraform destroy --auto-approve
+```
+
+```
+cd ..
+terraform destroy -target="module.eks_blueprints_addon" --var="kubecost_token=<your-kubecost-token>" -auto-approve
+terraform destroy -target="module.eks_blueprints_addons"
+terraform destroy -target="module.eks" -auto-approve
+terraform destroy -auto-approve
+```
