Install and Provision the Central Cloud

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

The Central Cloud supports either:

• with 0 or more Worker Nodes deployment
• Standard with dedicated Storage Nodes and 1 or more Worker Nodes deployment, or
• Standard with external Netapp Storage backend and 0 or more Worker Nodes deployment

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

You will also need to make the following modifications:

• 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.
