To do this, we will install some further packages to our controller node that we created in Chapter 1, Keystone – OpenStack Identity Service; Chapter 2, Glance – OpenStack Image Service; and Chapter 3, Neutron - OpenStack Networking, currently running Keystone and Glance. The services are as follows:
