I would like to know if there is a way, for example a command, to find out which RHOSP version is installed.
I understand that the command "openstack --version" gives the version of the unified CLI client rather than the OpenStack version itself.
Moreover, I'm not looking for the version of each individual component (e.g. Nova, Neutron, etc.), rather I'm looking for the version of the OpenStack collectively, e.g. RHOSP 10, 13, etc. or Newton, Queens, etc.
on the Director, you can view it from thiis file
# cat /etc/rhosp-release
Red Hat OpenStack Platform release 13.0.5 (Queens)
which is managed by the rpm
# rpm -qf /etc/rhosp-release
