Install and Provisioning the Central Cloud
==========================================

Installing the Central Cloud is similar to installing a standalone |prod|
system.

.. rubric:: |context|

The Central Cloud supports either

-  an |AIO|-Duplex deployment configuration

-  a Standard with Dedicated Storage Nodes deployment Standard with Controller
   Storage and one or more workers deployment configuration, or

-  a Standard with Dedicated Storage Nodes deployment configuration.


.. rubric:: |proc|

Complete the |prod| procedure for your deployment scenario with the
modifications noted above and below.

.. xbooklink For detailed |prod| deployment procedures, see :ref:`|inst-doc|
    <platform-installation-overview>`.

You will also need to make the following modification:

-  when creating the user configuration overrides for the Ansible bootstrap
   playbook in /home/sysadmin/localhost.yml.

   Add the parameters shown in bold below to your /home/sysadmin/localhost.yml
   Ansible bootstrap override file to indicate that this cloud will play the
   role of the Central Cloud / System Controller

-  restrict the range of addresses for the management network (using
   management_start_address and management_end_address, as shown below)  to
   exclude the IP addresses reserved for gateway routers that provide routing
   to the subclouds' management subnets.

-  Also, include the container images shown in bold below in
   additional\_local\_registry\_images, required for support of subcloud
   installs with the Redfish Platform Management Service, and subcloud installs
   using a Ceph storage backend...
