Trying to determine that version of Red Hat OpenStack director that is installed on an Undercloud Controller is not as straight forward as one would hope.
I have created the simple table below that you can use to determine your installed director version via the installed version of the openstack-tripleo-heat-templates rpm.
| Minimum RPM Version | Release Date | director Version |
| openstack-tripleo-heat-templates-0.8.6-123.el7ost | UNK | 7.3.1 |
| openstack-tripleo-heat-templates-0.8.6-94.el7ost.noarch.rpm | 2015-12-16 | 7.2 |
| openstack-tripleo-heat-templates-0.8.6-71.el7ost.noarch.rpm | 2015-10-05 | 7.1 |
| openstack-tripleo-heat-templates-0.8.6-45.el7ost.noarch.rpm | 2015-07-30 | 7.0 |
| openstack-tripleo-heat-templates-0.8.14-11.el7ost.noarch | 2016-04-20 | 8.0 |
| oopenstack-tripleo-heat-templates-2.0.0-41.el7ost.noarch | ?? | 9.0 |
| openstack-tripleo-heat-templates-5.2.0-15.el7ost.noarch | ?? | 10.0 |
| openstack-tripleo-heat-templates-6.0.0-10.el7ost.noarch | ?? | 11.0 |
Hopefully, in the near future, we will see an rpm similar to redhat-release-server (the rpm that create /etc/redhat-release) included in future OSP director updates. Until then, this table should be of some assistance.
