I frequently hear the following questions:
"Which OpenStack version is installed?" and "I am not able to determine the name of Openstack release running on my machine?"

So here is a quick way to find out:

  1. SSH to your openstack hosts.
  2. Run 
openstack --version

OpenStack Client Release Names:

  • Ocata 3.8.1
  • Newton 3.2.0
  • Mitaka 2.3.0
  • Liberty 1.7.3
  • Kilo 1.0.6
  • Juno 0.4.1
  • Icehouse 0.3.1

same way for other specific services  too, for example:

nova-manage --version
cinder-manage --version
glance-manage --version
