title: "Expose Kubecost with AWS Load Balancer Controller"
chapter: false

### Overview

In this module you will learn how to expose Kubecost for external access using the AWS Application Balancer (ALB). The AWS ALB manages AWS Elastic Load Balancers for a Kubernetes cluster. The controller provisions the following resources:

- An AWS Application Load Balancer (ALB) when you create a Kubernetes Ingress.

- An AWS Network Load Balancer (NLB) when you create a Kubernetes service of type LoadBalancer.

In this module, the Kubecost is exposed via a Kubernetes ingress and an AWS Application Load Balancer.

### Instructions

On the same Amazon EKS cluster on which you installed Kubecost, run the following command (copy & paste the entire code block) to create an Ingress object:

```bash
cat <<'EOF' |
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: kubecost-alb-ingress
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/target-type: ip
    alb.ingress.kubernetes.io/scheme: internet-facing
spec:
  rules:
    - http:
        paths:
        - path: /
          pathType: Prefix
          backend:
            service:
              name: kubecost-cost-analyzer
              port:
                number: 9090
EOF
(export NAMESPACE=kubecost && kubectl apply -n $NAMESPACE -f -)
```

After a few seconds, an AWS ALB is created. You can run the following command to get the DNS name for accessing the Kubecost user interface (UI):

```bash
export ENDPOINT=$(kubectl get ingress kubecost-alb-ingress -n kubecost --output jsonpath='{.status.loadBalancer.ingress[0].hostname}')
echo "Kubecost UI DNS name: ${ENDPOINT}"
```

Example result:

```bash
Kubecost UI DNS name: k8s-kubecost-kubecost-xxxxxxxxxx-xxxxxxxxxx.us-west-2.elb.amazonaws.com
```

In your web browser, navigate to ${ENDPOINT} to access the dashboard.

> Note: In some cases, you may need to wait for a few minutes before accessing the Kubecost UI to allow AWS to complete the provisioning process of the ALB.

You can learn more about Kubecost features in the next module.
