Chapter 4. Deploy the Configured Back End
The Director installation uses a non-root user to execute commands, which includes orchestrating the deployment of the Block Storage back end. In Creating a Director Installation User, a user named stack is created for this purpose. This user is configured with elevated privileges.
To deploy the lone back end configured in Chapter 3, Define a Single Back End, first log in as the stack user to the Undercloud. Then, deploy the back end (defined in the edited ~/templates/cinder-dellps-config.yaml) by running the following:
$ openstack overcloud deploy --templates -e ~/templates/cinder-dellps-config.yaml
If you passed any extra environment files when you created the overcloud, pass them again here using the -e option to avoid making undesired changes to the overcloud. For more information, see Modifying the overcloud environment in the Director Installation and Usage guide.
