# Configure Cluster Ingress

{% hint style="warning" %}
Manually configuration of Cluster Ingress is not necessary if [External IP Allowlisting](https://docs.e6data.com/product-documentation/~/revisions/W5MExJCuvHiG1ioEcgOy/connectors-and-drivers/broken-reference) is done.
{% endhint %}

When connecting tools like Tableau or JDBC drivers to an e6data cluster, [Ingress](#what-is-ingress-in-kubernetes) must first be configured in a customer's Kubernetes cluster. Below are a few tutorials to securely configure ingress in different scenarios.

1. [Configuring ALB Ingress in Kubernetes](https://docs.e6data.com/product-documentation/~/revisions/W5MExJCuvHiG1ioEcgOy/connectors-and-drivers/configure-cluster-ingress/alb-ingress-in-kubernetes)
2. [Configuring GCE Ingress in Kubernetes](https://docs.e6data.com/product-documentation/~/revisions/W5MExJCuvHiG1ioEcgOy/connectors-and-drivers/configure-cluster-ingress/gce-ingress-in-kubernetes)

## What is Ingress in Kubernetes? <a href="#what-is-ingress-in-kubernetes" id="what-is-ingress-in-kubernetes"></a>

In Kubernetes, an Ingress is an API object that provides external access to [Services](#what-is-a-service-in-kubernetes) within a cluster. It acts as a layer 7 (HTTP/HTTPS) load balancer and allows you to define routing rules to direct incoming traffic to different services based on the URL path or domain.

## What is a Service in Kubernetes?

In Kubernetes, a Service is an abstraction that defines a logical set of pods and a policy by which to access them. It provides a consistent way to access and communicate with your application's pods, regardless of their dynamic nature (pods can be created, terminated, or scaled up/down).
