Metal LB
========

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

#. From the OCP Console select :menuselection:`Operators --> OperatorHub`. In
   the search box type "metallb".

   .. image:: ./images/metallb-operatorhub.png

#. Click Install. Leave defaults and Click Install again.

   .. image:: ./images/metallb-install.png

   .. image:: ./images/metallb-install2.png

#. After operator installation completes, click "View Operator".

#. Click "Create instance" to create the Metal LB instance.

   .. image:: ./images/metallb-instance.png

#. Accept the defaults and click “Create” at the bottom of the page.

.. tip:: To expose the VIP with a service see:
   `Quick App Deployment <./openshift-day2.html#quick-app-deployment-route>`_

   There you'll find how to deploy a generic httpd service and expose a
   LoadBalancer Service.

.. important:: You need a LoadBalancer Service for this to work.
