Step 8: Create a Custom DNS Name (Optional)

Changing the DNS Name for ease of use

After you create a Load Balancer Listener you can modify the DNS Name for ease of use and reference by your applications. It isn't necessary to run your application or complete this tutorial.

To skip this step, proceed to test your application and complete this tutorial.

Once the Load Balancer is created, DuploCloud programs an autogenerated DNS Name registered to demo-service in the Route 53 domain. Before you create production deployments, you must create the Route 53 Hosted Zone domain (if DuploCloud has not already created one for you). For this tutorial, it is not necessary to create a domain.

Estimated time to complete Step 8: 5 minutes.

Prerequisites

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

• An Infrastructure and Plan exist, both named NONPROD.

• The NONPROD infrastructure has EKS Enabled.

• A Tenant named dev01 has been created.

• A Host named host01 has been created.

• A Service named demo-service has been created.

• An HTTPS ALB Load Balancer has been created.

Creating a Custom DNS Name

1. In the Tenant list box, select the dev01 Tenant.

2. Navigate to Kubernetes -> Services. The Services page displays.

3. From the Name column, select demo-service.

4. Click the Load Balancers tab. The ALB Load Balancer configuration is displayed.

5. In the DNS Name card, click Edit. The prefix in the DNS Name is editable.

6. Edit the DNS Name and select a meaningful DNS Name prefix.

7. Click Save. A success message briefly displays at the top center of the DuploCloud Portal.

An entry for your new DNS name is now registered with demo-service.

Checking Your Work

1. Navigate to Kubernetes -> Services.

2. From the Name column, select demo-service.

3. Select the Load Balancers tab and verify that the DNS Name card displays your modified DNS Name.
