For some time, devstack has been running with keystone accepting on both
it's legacy ports (:5000 and :35357), and on subpaths (:80/identity and
/identity_admin). I tried to change devstack to have keystone only
listening on subpaths but this is failing in tempest-lib -- see the errors
in https://review.openstack.org/#/c/193894/. At first I thought it would be
best to get tempest-lib doing version discovery but this turned into a lot
of code since version discovery requires quite a bit of parsing and
searching through dicts which always requires lots of error handling and
test code (see reviews ending at https://review.openstack.org/#/c/263452/).
(You might wonder why I didn't use the code that's already in
keystoneclient/keystoneauth for version discovery -- it's because tempest
doesn't use the client libs.)
Anyways I think the alternative that's going to be backwards compatible is
to have the user be able to pass in the identity endpoints for v2 and v3
and have tempest use those if provided. I haven't had time to propose this
My preference would be to have the keystone processes running separately
under uwsgi or gunicorn, then httpd proxies to that from /identity and
/identity_admin (and :5000 and :35357 for legacy). Hopefully this would be
over a unix socket talking uwsgi protocol or whatever the process and httpd
support. Note that devstack already has a TLS-proxy deployment option
that's similar. I've been hoping to have time to propose the keystone
devstack deployment use this but I'm easily distracted.
