Description

Intersphinx mapping settings in docs/conf.py need to point to specific versions which correspond to the version of the lbaasv1 doc from which the clicks the link out to the other doc set.

For Kilo:

intersphinx_mapping = {'heat': (
     'http://f5-openstack-docs.readthedocs.io/en/1.0/', None),
     'docs': (
     'http://f5-openstack-docs.readthedocs.io/en/1.0/', None),
     #'lbaasv2': (
     #'http://f5-openstack-docs.readthedocs.io/en/1.0/', None), \\ commented out because there is no corresponding branch in lbaasv2
     }

For Liberty:

intersphinx_mapping = {'heat': (
     'http://f5-openstack-docs.readthedocs.io/en/liberty/', None),
     'docs': (
     'http://f5-openstack-docs.readthedocs.io/en/liberty/', None),
     'lbaasv2': (
     'http://f5-openstack-docs.readthedocs.io/en/liberty/', None),
     }

For Mitaka:

intersphinx_mapping = {'heat': (
     'http://f5-openstack-docs.readthedocs.io/en/mitaka/', None),
     'docs': (
     'http://f5-openstack-docs.readthedocs.io/en/mitaka/', None),
     'lbaasv2': (
     'http://f5-openstack-docs.readthedocs.io/en/mitaka/', None),
     }
