Learn how to modify your existing Vultr Load Balancer configuration to adapt to changing requirements.

Updating a Vultr Load Balancer enables you to modify various settings, including changing its label for better identification within your infrastructure. This process does not affect the functionality, traffic distribution, or configuration of the Load Balancer. By adjusting the label, you can easily manage multiple Load Balancers, ensuring clear tracking across your environment.

Follow this guide to update the label of a Vultr Load Balancer on your Vultr account using the Vultr Customer Portal, API, CLI, or Terraform.

        "label": "{updated_label}"
    }'
