Making system configuration changes

In order to make configuration changes to your system, you must use the Admin panel from within Workflow Designer.

The panel provides users with a place to perform a variety of configuration tasks meant to help maintain and optimize their systems. In lieu of the Admin App previously featured in the HCI 2.x product, this panel and all of its associated settings are intended to help bridge the gap between system management and your Kubernetes environment.

To access these configuration options:

Open Workflow Designer.
On the left-hand side of the page, click the Admin panel.
