# Step 6: Create a Load Balancer

Creating a Load Balancer to configure network ports to access the application

Now that your DuploCloud Service is running, you have a mechanism to expose the containers and images in which your application resides. However, since your containers are inside a private network, you need a Load Balancer listening on the correct ports to access the application.

In this step, we add a Load Balancer Listener to complete the network configuration.

*Estimated time to complete Step 6: 10 minutes.*

## Prerequisites

Before creating a Load Balancer, verify that you completed the tasks in the previous tutorial steps. Using the DuploCloud Portal, confirm that:

* An [Infrastructure and Plan](/docs/automation-platform/overview/quick-start/step-1-infrastructure.md) exist, both named **NONPROD**.
* The **NONPROD** infrastructure has [EKS **Enabled**](/docs/automation-platform/overview/quick-start/step-1-infrastructure.md#check-your-work).
* A Tenant named [**dev01** has been created](/docs/automation-platform/overview/quick-start/step-2-tenant.md).
* A Host named [**host01** has been created](/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-3-create-host.md).
* A Service named [**demo-service** has been created](/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-5-create-app-via-k8s.md).

## Creating a Load Balancer

1. In the **Tenant** list box, select the **dev01** Tenant.
2. In the DuploCloud Portal, navigate to **Kubernetes** -> **Services**.
3. From the **NAME** column, select **demo-service**.
4. Click the **Load Balancers** tab.
5. Click the **Configure Load Balancer** link. The **Add Load Balancer Listener** pane displays.

6. From the **Type** list box, select **Application LB**.
7. In the **Container Port** field, enter **3000**. This is the configured port on which the application inside the Docker Container Image `duplocloud/nodejs-hello:latest` is running.
8. In the **External Port** field, enter **80**. This is the port through which users will access the web application.
9. From the **Visibility** list box, select **Public**.
10. From the **Application Mode** list box, select **Docker Mode**.
11. Type **/** (forward-slash) in the **Health Check** field to indicate that the cluster we want Kubernetes to perform Health Checks on is located at the `root` level.
12. In the **Backend Protocol** list box, select **HTTP**.
13. Click **Add**. The Load Balancer is created and initialized. Monitor the **LB Status** card on the **Services** page. The **LB Status** card displays **Ready** when the Load Balancer is ready for use.

## Checking your work

1. In the **Tenant** list box, select the **dev01** Tenant.
2. In the DuploCloud Portal, navigate to **Kubernetes** -> **Services**.
3. From the **NAME** column, select **demo-service**.
4. Verify that the **LB Status** card displays a status of **Ready**.
5. Note the **DNS** Name of the Load Balancer that you created.
6. In the **LB Listeners** area of the **Services** page, note the configuration details of the Load Balancer's **HTTP** protocol, which you specified, when you added it above.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.duplocloud.com/docs/automation-platform/overview/quick-start/quick-start-eks-services/step-6-create-a-load-balancer.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
