Metal LB

Quick examples on configuring this operator. I’m assuming the operator is installed.

From the OCP Console select Operators ‣ OperatorHub. In the search box type “metallb”.
Click Install. Leave defaults and Click Install again.
After operator installation completes, click “View Operator”.
Click “Create instance” to create the Metal LB instance.
Accept the defaults and click “Create” at the bottom of the page.
